Description

The present invention relates to a powder-containing cosmetic that can stably incorporate powder, and a method for producing the powder-containing cosmetic.

Powder-containing cosmetics that contain powder in the cosmetic composition are known. When powder-containing cosmetics are applied to the skin, the powder adheres to the skin, forming a cosmetic film and enabling the powder to exert its cosmetic effects. For this reason, it is extremely important for powder-containing cosmetics that the powder adheres to the skin (excellent adhesion). Talc, titanium oxide, and zinc oxide, in particular, are widely used as powders in powder-containing cosmetics, as they enhance adhesion to the skin. However, when these powders are used, although their improved adhesion to the skin can sometimes lead to problems such as the powder being prone to agglomeration, making it difficult to achieve a uniform dispersion of the powder.

Furthermore, solid powder cosmetics, in which powder-containing cosmetics are formed into a solid form, are known as one type of powder-containing cosmetic. Solid powder cosmetics can generally be formed by dry forming, in which a powder composition is filled into a container such as a metal dish and then pressurized, or by wet forming, in which a cosmetic base containing powder and oil is added with a volatile component to form a slurry, which is then filled into a container such as a metal dish, and the solvent is removed and formed. Of these, solid powder cosmetics obtained by wet forming have a smooth feel when used because the powder is packed more densely when the solvent is removed from the slurry. However, if the powder remains aggregated, problems such as the formation of aggregates (also known as black lumps) that are noticeable as foreign matter on the surface, a deterioration in feel when used (a squeaky feeling due to the powder), a difference between the appearance color of the cosmetic and the applied color, and uneven color in the cosmetic film can occur. In particular, when powders such as talc, titanium oxide, and zinc oxide are blended, and surfactants and oils are also added to enhance adhesion, aggregation becomes more likely, and it is not easy to simultaneously improve adhesion to the skin while suppressing powder aggregation.

As a result, various dispersion technologies have been developed to stably disperse powders, including the use of surface treatment agents, the addition of surfactants or water-soluble polymers, and the addition of clay minerals. For example, Patent Documents 1 and 2 disclose a technique for dispersing powders by adding behendimonium ethyl stearyl phosphate.

Contains:
In this specification, (A) to (D) and (E) are symbolic symbols of the components, and hereinafter may be referred to as component (A), etc.

Component (A)
Component (A) is a gemini surfactant. A gemini surfactant is a surfactant having a structure in which two molecules of a one-hydrophobic-chain, one-hydrophilic-group surfactant are covalently bonded via a spacer. That is, a gemini surfactant has a structure of (surfactant portion)-(spacer portion)-(surfactant portion). Gemini surfactants are often known to have a higher interfacial tension reducing ability (or a low CMC) than the interfacial tension reducing ability of the surfactant portion in a single molecule, thereby achieving high interfacial activity. Gemini surfactants facilitate the adhesion of powder to the skin, allowing for the production of powder-containing cosmetics with long-lasting makeup. Furthermore, gemini surfactants enable powder-containing ingredients to be effectively molded into a solid form, resulting in powder-containing cosmetics with excellent impact resistance. For details about gemini surfactants, see, for example, "Gemini Surfactants: Their Chemical Structure and Interfacial Properties," Oleoscience, 2011, Vol. 11, No. 9, pp. 313-318. Examples of gemini surfactants include, but are not limited to, the following components (A1) to (A3).

Component (A) is at least one of the following components (A1) to (A3):
(A1) behendimonium ethyl stearyl phosphate;
(A2) a compound represented by formula (1); and
(A3) a compound represented by formula (I) or a salt thereof,
It is preferably selected from the group consisting of:
Components (A1) to (A3) will be described below.

Component (A1)
Component (A1), behendimonium ethyl stearyl phosphate, is a compound having a group (-N ⁺ (CH ₃ ) ₂ (CH ₂ ) ₂ -O-PO ₃ ^- -) in the molecule similar to that of phosphocholine (hereinafter referred to as a "phosphorylcholine-like group"), and specifically, is a compound having the following structure:
C ₂₂ H ₄₅ -N ⁺ (CH ₃ ) ₂ -(CH ₂ ) ₂ -O-PO ₃ ^- -C ₁₈ H ₃₇

As shown in the structure above, behendimonium ethyl stearyl phosphate consists of a surfactant moiety in which a hydrophobic behenyl group is bonded to a quaternary ammonium salt (corresponding to a first one-hydrophobic-chain one-hydrophilic-group surfactant) and a surfactant moiety in which a hydrophobic stearyl group is bonded to a phosphate group (corresponding to a second one-hydrophobic-chain one-hydrophilic-group surfactant), covalently bonded via a spacer alkylene chain. Therefore, behendimonium ethyl stearyl phosphate is a gemini surfactant. Furthermore, because behendimonium ethyl stearyl phosphate contains both cationic and anionic moieties, it is classified as an amphoteric surfactant. Because of its structure, behendimonium ethyl stearyl phosphate has a very high affinity for skin. However, its relatively small molecular weight facilitates interaction with powders, allowing it to easily bond to the powder surface, preventing powder aggregation and facilitating good powder dispersion in the composition. Furthermore, by improving powder dispersibility, it is believed to help powders adhere evenly to the skin. Therefore, when component (A1) is incorporated into a powder-containing cosmetic, the powder adheres easily to the skin (facilitating the formation of a cosmetic film), and effects such as a lack of powdery feeling and a lack of powdery texture (uniformity of the cosmetic film) are easily achieved. Furthermore, behendimonium ethyl stearyl phosphate has a good balance of lipophilicity and hydrophilicity, and is excellent in water and oil repellency, so it can also impart effects such as improved makeup wear. Commercially available behendimonium ethyl stearyl phosphate can be used.

Ingredients (A2)
Component (A2) is a compound represented by formula (1):
[In the formula, R ¹ is an unsaturated or saturated hydrocarbon group having 12 to 22 carbon atoms, R ⁴ is an unsaturated or saturated hydrocarbon group having 12 to 22 carbon atoms, and at least one of R ¹ and R ⁴ is an unsaturated hydrocarbon group having 12 to 22 carbon atoms; and R ² and R ³ may be the same or different and each independently represent an alkyl group having 1 to 6 carbon atoms or a hydroxyalkyl group having 1 to 6 carbon atoms.]
(hereinafter referred to as "PC compound" in this specification).

Component (A2) is a compound (PC compound) containing a phosphorylcholine-like group, as shown in the structure above. As shown in the structure above, the PC compound has a surfactant moiety in which the hydrophobic group ^R1 is bonded to a quaternary ammonium salt (corresponding to a first one-hydrophobic chain one-hydrophilic group surfactant) and a surfactant moiety in which the hydrophobic group ^R4 is bonded to a phosphate group (corresponding to a second one-hydrophobic chain one-hydrophilic group surfactant), covalently bonded via a spacer alkylene chain. Therefore, the PC compound is a gemini surfactant.

In formula (1), ^R1 is an unsaturated or saturated hydrocarbon group having 12 to 22 carbon atoms, i.e., ^R1 is an unsaturated hydrocarbon group having 12 to 22 carbon atoms, or a saturated hydrocarbon group having 12 to 22 carbon atoms. Furthermore, ^R4 is an unsaturated or saturated hydrocarbon group having 12 to 22 carbon atoms, i.e., ^R4 is an unsaturated hydrocarbon group having 12 to 22 carbon atoms, or a saturated hydrocarbon group having 12 to 22 carbon atoms. However, at least one of ^R1 and ^R4 is an unsaturated hydrocarbon group having 12 to 22 carbon atoms. In other words, both ^R1 and ^R4 are unsaturated hydrocarbon groups having 12 to 22 carbon atoms, or ^R1 is an unsaturated hydrocarbon group having 12 to 22 carbon atoms and ^R4 is a saturated hydrocarbon group having 12 to 22 carbon atoms, or ^R1 is a saturated hydrocarbon group having 12 to 22 carbon atoms and ^R4 is an unsaturated hydrocarbon group having 12 to 22 carbon atoms. There is no case where both R ¹ and R ⁴ are saturated hydrocarbon groups having 12 to 22 carbon atoms.

In one embodiment, one of ^R1 and ^R4 is an unsaturated hydrocarbon group having 12 to 22 carbon atoms, and the other is a saturated hydrocarbon group having 12 to 22 carbon atoms. In this case, the dispersibility of the powder can be further improved. That is, it is preferable that ^R1 is an unsaturated hydrocarbon group having 12 to 22 carbon atoms, and ^R4 is a saturated hydrocarbon group having 12 to 22 carbon atoms, or that ^R1 is a saturated hydrocarbon group having 12 to 22 carbon atoms, and ^R4 is an unsaturated hydrocarbon group having 12 to 22 carbon atoms. Furthermore, it is more preferable that ^R1 is an unsaturated hydrocarbon group having 12 to 22 carbon atoms, and ^R4 is a saturated hydrocarbon group having 12 to 22 carbon atoms. In this case, the dispersibility of the powder is further improved. It is also preferable that one of ^R1 and ^R4 is an unsaturated hydrocarbon group having 18 carbon atoms, and the other of ^R1 and ^R4 is a saturated hydrocarbon group having 22 carbon atoms. The saturated hydrocarbon group may be, for example, what is called an alkyl group. The unsaturated hydrocarbon group may be, for example, what is called an alkenyl group or an alkynyl group.

In ^R1 and ^R4 (the following descriptions of ^R1 and ^R4 apply independently unless otherwise specified), the unsaturated or saturated hydrocarbon group having 12 to 22 carbon atoms may be linear, branched, or cyclic. The unsaturated or saturated hydrocarbon group of ^R1 and ^R4 is preferably a linear or branched hydrocarbon group, more preferably a linear hydrocarbon group. In particular, it is preferable that both ^R1 and ^R4 are linear or branched hydrocarbon groups, and it is even more preferable that both are linear hydrocarbon groups. The unsaturated or saturated hydrocarbon group having 12 to 22 carbon atoms may be a hydrocarbon group (e.g., an aliphatic alkyl group or alkenyl group) having a structure obtained by removing a hydroxy group (OH) from a monohydric aliphatic alcohol. The saturated hydrocarbon group of ^R1 and ^R4 preferably has 16 to 22 carbon atoms, and even more preferably has 18 to 22 carbon atoms.

The saturated hydrocarbon group having 12 to 22 carbon atoms for ^R1 and ^R4 is not limited thereto, but examples of linear groups include lauryl (12 carbon atoms; also called dodecyl group), myristyl (14 carbon atoms; also called tetradecyl group), cetyl (16 carbon atoms; also called hexadecyl group), stearyl (18 carbon atoms; also called octadecyl group), and behenyl (22 carbon atoms; also called docosyl group), and examples of branched groups include isostearyl (18 carbon atoms; also called 16-methylheptadecyl group). Of these, stearyl and behenyl groups are preferred, with behenyl being more preferred.

In the unsaturated hydrocarbon groups having 12 to 22 carbon atoms in ^R1 and ^R4 , the unsaturation may be either a carbon-carbon double bond unsaturation or a carbon-carbon triple bond unsaturation, but is preferably a carbon-carbon double bond unsaturation. Unsaturated hydrocarbon groups having a carbon-carbon double bond are also called alkenyl groups. The number of unsaturations is preferably 1 to 3, more preferably 1 or 2, and even more preferably 1. When the number of unsaturations is two or more, it is preferable that all of them are carbon-carbon double bond unsaturations. The number of carbon atoms in the unsaturated hydrocarbon groups in ^R1 and ^R4 is preferably 16 to 22.

In formula (1), it is more preferable that at least one of ^R1 and ^R4 is an unsaturated hydrocarbon group having 18 carbon atoms. In this case, the dispersibility of the powder can be further improved. Furthermore, it is even more preferable that at least one of ^R1 and ^R4 is an unsaturated hydrocarbon group having 18 carbon atoms and having 1 to 3 carbon-carbon double bonds. This can further improve the dispersibility of the powder. The number of carbon-carbon double bonds is more preferably 1 or 2, and even more preferably 1. Examples of unsaturated hydrocarbon groups having 18 carbon atoms include an oleyl group, an elaidyl group, a linoleyl group (polyunsaturated), and a linoleyl group (polyunsaturated), and of these, an oleyl group is more preferable. The oleyl group is also called a cis-9-octadecenyl group.

In one preferred embodiment, one of ^R1 and ^R4 is an oleyl group, and the other is a group selected from the group consisting of an oleyl group, a behenyl group, and a stearyl group.

Specific combinations of ^R1 and ^R4 , when expressed as ( ^R1 , ^R4 ), include, but are not limited to, combinations such as (oleyl group, behenyl group), (behenyl group, oleyl group), (oleyl group, stearyl group), (stearyl group, oleyl group), (oleyl group, oleyl group), etc. Of these, the combinations (oleyl group, behenyl group) and (behenyl group, oleyl group) are more preferred.

In formula (1), ^R2 and ^R3 (the following explanations of ^R2 and ^R3 apply independently unless otherwise specified) are each independently selected from the group consisting of alkyl groups having 1 to 6 carbon atoms and hydroxyalkyl groups having 1 to 6 carbon atoms. Here, the alkyl moiety in the alkyl or hydroxyalkyl may be linear or branched. Preferably, the alkyl moiety is linear. ^R2 and ^R3 may be the same or different, but from the viewpoint of producing a PC compound, it is more preferable that they are the same.

In ^R2 and ^R3 , examples of the alkyl group having 1 to 6 carbon atoms include, for example, linear methyl, ethyl, propyl, butyl, pentyl, and hexyl groups, and branched alkyl groups include isopropyl and isobutyl groups. Preferred examples of the alkyl group having 1 to 6 carbon atoms include a methyl group ( _-CH3 ), an ethyl group ( _{-CH2CH3 )} , _and a propyl group ( _-CH2CH2CH3 ), _with a methyl group ( _-CH3 ) being more preferred.

In ^R2 and ^R3 , the hydroxyalkyl group having 1 to 6 carbon atoms is an alkyl group substituted with one or more hydroxy groups, and a hydroxyalkyl group having a terminal hydroxy group (1 to 3, preferably 1 to 2, more preferably 1) is preferred. Examples of the hydroxyalkyl group having 1 to 6 carbon atoms include a hydroxymethyl group, a hydroxyethyl group, and a hydroxypropyl group. As the hydroxyalkyl group having 1 to 6 carbon atoms, a hydroxyethyl group ( _-CH2CH2OH ) having one terminal _hydroxy group is more preferred.

It is preferable that ^R2 and ^R3 are each independently a methyl group or a hydroxyethyl group. In this case, the dispersibility of the powder can be further improved. Furthermore, it is more preferable that both ^R2 and ^R3 are methyl groups or both are _hydroxyethyl groups (particularly _-CH2CH2OH ).

In a preferred embodiment of the compound of formula (1), at least one of ^R1 and ^R4 is an unsaturated hydrocarbon group having 18 carbon atoms, and ^R2 and ^R3 are each independently a methyl group or a _hydroxyethyl group (particularly _-CH2CH2OH ). In this case, the dispersibility of the powder can be further improved.

Specific combinations of R ¹ , R ² , R ³ and R ⁴ are not limited to these, but when expressed as (R ¹ , R ² , R ³ , R ⁴ ), examples of combinations include (oleyl group, methyl group, methyl group, behenyl group), (behenyl group, methyl group, methyl group, oleyl group), (oleyl group, hydroxyethyl group, hydroxyethyl group, behenyl group), and (behenyl group, hydroxyethyl group, hydroxyethyl group, oleyl group).

A method for producing a PC compound will now be described. The PC compound represented by formula (1) is obtained by reacting an alcohol represented by formula (2) with 2-chloro-2-oxo-1,3,2-dioxaphospholane (hereinafter abbreviated as COP) in the presence of an organic base to produce an intermediate, and then ring-opening the intermediate with a tertiary amine represented by formula (3). The resulting PC compound can be purified by common purification methods such as reprecipitation and recrystallization.
R ¹ , R ² , R ³ and R ⁴ in formula (2) and formula (3) have the same meanings as those in formula (1).

The PC compound represented by formula (1) is a compound that contains within its molecule a group (hereinafter referred to as a "phosphorylcholine-like group") with a structure similar to that of phosphorylcholine (-N ⁺ (CH ₃ ) ₂ (CH ₂ ) ₂ -O-PO ₃ ^- -). The phosphorylcholine-like group is a polar group that functions as a hydrophilic group. In addition, unsaturated or saturated hydrocarbon groups are bonded to both sides of the phosphorylcholine-like group, and these hydrocarbon groups function as hydrophobic groups. Therefore, PC compounds can also have surfactant properties. Due to this structure and properties, PC compounds have extremely high affinity for the skin, while their relatively small molecular weight makes them more likely to interact with powder and bond to the powder surface, making the powder less likely to aggregate and allowing the powder to be well dispersed in the composition. It is also thought that improving the dispersibility of the powder helps the powder to adhere evenly to the skin. Therefore, when component (A2) is incorporated into a powder-containing cosmetic, the powder adheres easily to the skin (facilitating the formation of a cosmetic film), and effects such as a lack of powdery feeling and a lack of powdery texture (uniformity of the cosmetic film) are easily achieved. Furthermore, the presence of an unsaturated bond in the hydrophobic portion of the molecule of the compound of formula (1) increases the solubility of component (C) in oils, making it easier for component (B) to bond uniformly, thereby further improving the dispersibility of the powder and improving adhesion and cosmetic longevity. Furthermore, PC compounds have a good balance of lipophilicity and hydrophilicity and are excellent in water and oil repellency, so they can impart effects such as improved cosmetic longevity.

Component (A2) may consist of a single compound of formula (1), or may contain multiple compounds of formula (1) with different structures (a mixture).

Note that component (A1), behendimonium ethyl stearyl phosphate, is a compound in which ^R1 is a behenyl group, ^R2 and ^R3 are both methyl groups, and ^R4 is a stearyl group in the above formula (1), but since both ^R1 and ^R4 are saturated hydrocarbon groups, it is not included in component (A2).

Ingredients (A3)
Component (A3) is a compound represented by formula (I): X-Y-X (I)
[In the formula, each X is independently an N-acylamino acid residue having an acyl group having 10 to 20 carbon atoms and consisting of a saturated or unsaturated chain hydrocarbon group and a carbonyl group, and an amino acid bonded to the acyl group via an amino group; and Y is a spacer connecting the two Xs.]
or a salt thereof (hereinafter, the compound, including the salt, may be referred to as an N-acyl amino acid derivative compound).

Component (A3) is a gemini surfactant in which X is the surfactant moiety and Y is a spacer. Within the N-acylamino acid residue, the saturated or unsaturated chain hydrocarbon group is the hydrophobic moiety, and the amino acid is the hydrophilic moiety. N-acylamino acid derivative compounds contain a moiety derived from an amino acid, and because amino acids have high affinity for the body, they adhere easily to the skin, allowing for the production of powder-containing cosmetics with long-lasting cosmetic wear. In addition, the chain hydrocarbon group in the surfactant moiety allows for good dispersion of powder.

In component (A3), there are two Xs, which are surfactant moieties. The two Xs may be the same or different, but are preferably the same. X is composed of a residue of an N-acylamino acid. An N-acylamino acid is a compound in which a hydrocarbon group is bonded to the amino group of an amino acid via a carbonyl group. This bond can be formed by an amide bond between the acyl group and the amino group of the amino acid. In an N-acylamino acid derivative compound, the N-acylamino acid is composed of an acyl group having 10 to 20 carbon atoms, consisting of a saturated or unsaturated chain hydrocarbon group and a carbonyl group, and an amino acid bonded to the acyl group via an amino group. The acyl group has 10 to 20 carbon atoms, and therefore the number of carbon atoms in the hydrocarbon group in the acyl group is 9 to 19, minus one carbon atom for the carbonyl. Therefore, N-acylamino acids can also be said to be acyl groups consisting of a saturated or unsaturated chain hydrocarbon group having 9 to 19 carbon atoms and a carbonyl group (where the total carbon number of the acyl group is 10 to 20).

The saturated or unsaturated chain hydrocarbon group represented by X in formula (I) may be either linear or branched, but is preferably linear. The saturated or unsaturated hydrocarbon group may be a hydrocarbon group (e.g., an aliphatic alkyl group or alkenyl group) having a structure in which a hydroxyl group (OH) has been removed from a monovalent aliphatic alcohol. The hydrocarbon group preferably has 11 to 17 carbon atoms, more preferably 11 to 15. The number of carbon atoms in the hydrocarbon group does not include the carbon (one) of the carbonyl group. The saturated or unsaturated chain hydrocarbon group is preferably a saturated hydrocarbon group. On the other hand, in the case of unsaturated hydrocarbons, the unsaturation may be either a carbon-carbon double bond unsaturation or a carbon-carbon triple bond unsaturation, but is preferably a carbon-carbon double bond unsaturation. An unsaturated hydrocarbon group having a carbon-carbon double bond is also referred to as an alkenyl group. The number of unsaturations is preferably 1 to 3, more preferably 1 or 2, and even more preferably 1. If there are two or more unsaturations, it is preferable that all of them are carbon-carbon double bond unsaturations.

A saturated or unsaturated chain hydrocarbon group (R) bonds with a carbonyl group (C═O) to form an acyl group (R—C(═O)—). This acyl group forms an amide bond (—C(═O)—N—) with the amino group (—NH ₂ or —NH—) of the amino acid moiety in the N-acylamino acid to form an N-acylamino acid. An acyl group having such a hydrocarbon group bonded thereto is sometimes referred to as an alkyloyl group. The number of carbon atoms in the acyl group may be 10 to 20, more preferably 12 to 18, and even more preferably 12 to 16. Here, the number of carbon atoms in the acyl group includes the carbon atom in the carbonyl group, i.e., the total number of carbon atoms in the hydrocarbon group and the carbonyl group. The number of carbon atoms in the acyl group is more preferably 12. In other words, the acyl group is preferably a lauroyl group (an acyl group having 12 carbon atoms and a saturated alkyl group; an undecylcarbonyl group).

Amino acids that are constituent elements of the N-acyl amino acid in X of formula (I) include, but are not limited to, lysine, glutamic acid, arginine, aspartic acid, glutamine, proline, and serine.

In formula (I), the N-acyl amino acid exists as an N-acyl amino acid residue, with one of its functional groups (e.g., a carboxy group, an amino group, etc.) bound to the spacer Y.

The spacer Y has a chemical structure that links the two Xs (surfactant moieties). Y preferably has at least two functional groups that bond to X. The bond between X and Y in formula (I) is a covalent bond, preferably an amide bond. Y can be composed of an organic compound. Examples of compounds that constitute Y include compounds having two or more carboxylic acids and compounds having two or more amino groups. Y may also be composed of an amino acid. Examples of compounds that constitute Y include compounds having two carboxylic acids such as sebacic acid, succinic acid, adipic acid, phthalic acid, aspartic acid, and glutamic acid, and examples of compounds having two amino groups such as lysine, arginine, and histidine. Examples of amino acids that constitute Y include lysine, glutamic acid, and aspartic acid.

The N-acyl amino acid derivative compound of component (A3) is preferably a compound in which the acyl group in the N-acyl amino acid of the surfactant moiety is selected from the group consisting of lauroyl, myristoyl, palmitoyl, and stearoyl groups, the amino acid is selected from the group consisting of lysine, glutamic acid, arginine, aspartic acid, glutamine, proline, and serine, and the spacer is selected from the group consisting of sebacic acid, lysine, succinic acid, adipic acid, phthalic acid, aspartic acid, glutamic acid, arginine, and histidine.

The N-acylamino acid derivative compound may be in the form of a salt. The salt is preferably a cosmetically acceptable salt. The salt may also be a pharmaceutically acceptable salt. The salt is preferably a salt formed from a carboxylic acid and an alkali metal. Examples include sodium salts and potassium salts.

Specific preferred examples of component (A3) include sebacoyl bislauramide lysine and its salts (e.g., sodium salt, potassium salt), dilauroyl glutamic acid lysine and its salts (e.g., sodium salt, potassium salt). These are commercially available or can be prepared by known methods.

In particular, sebacoyl bislauramide lysine disodium is a compound derived from lauric acid, L-lysine, and sebacic acid, and has the following structure (lysine is also called lysine):

Furthermore, dilauroyl glutamic acid lysine and dilauroyl glutamic acid lysine sodium are compounds derived from lauric acid, glutamic acid, and lysine, and have the following structure:

Component (A3) may be a single compound or a mixture of multiple compounds.

Component (A) may be one, two, or all three of the above-mentioned components (A1), (A2), and (A3). It is preferable that at least one of the components (A) is (A1) behendimonium ethyl stearyl phosphate or (A2) a compound represented by formula (1). This allows for the production of a powder-containing cosmetic with higher adhesiveness.

The content of component (A) in the composition (the total amount when multiple components are present) is not limited to the above, but from the viewpoint of powder dispersibility and achieving a good feel when used, it can be, for example, 0.0001 to 10% by mass, and preferably 0.001 to 7% by mass, relative to the total amount of the composition (100% by mass). Furthermore, the content of component (A) is preferably 0.005 to 5% by mass, more preferably 0.01 to 3% by mass, and even more preferably 0.05 to 2% by mass, relative to the total amount of the composition. In this case, a composition with high powder dispersibility can be obtained.

Ingredient (B)
Component (B) is one or more powders selected from the group consisting of talc, titanium oxide, and zinc oxide. Talc, titanium oxide, and zinc oxide have excellent adhesion to the skin, making it possible to obtain powder-containing cosmetics with good adhesion. Furthermore, these powders can enhance the functions of the powder-containing cosmetics, such as makeup effects, UV scattering effects, and improved usability.

Talc that is commonly used in cosmetics can be used without particular limitations, such as its shape (e.g., spherical, plate-like, needle-like, or irregular), or its particle structure (e.g., porous or non-porous). For example, talc with an average particle diameter of 2 to 30 μm can be used. In this specification, the average particle diameter of the powder is the volume average particle diameter measured using a laser diffraction particle size distribution analyzer.

Titanium oxide can be any titanium oxide commonly used in cosmetics, and is not particularly limited in shape (e.g., spherical, plate-like, needle-like, irregular, etc.) or particle structure (e.g., porous, non-porous, etc.). Furthermore, titanium oxide may be of either rutile or anatase type. Titanium oxide with an average particle diameter of, for example, 10 to 1,000 nm can be used.

As long as the zinc oxide is zinc oxide that is commonly used in cosmetics, it can be used without any particular limitations on its shape (e.g., spherical, plate-like, needle-like, irregular, etc.) or particle structure (e.g., porous, non-porous, etc.). For example, zinc oxide with an average particle diameter of 10 to 5,000 nm can be used.

The talc, titanium oxide, and zinc oxide powders may each be powders whose surfaces have been treated with a surface treatment agent (surface-treated powders). Surface treatment can further inhibit powder aggregation. Surface treatment can also increase the powder's adhesiveness. Furthermore, surface treatment can improve the functionality (usage feel, etc.) of the powder. Examples of surface treatments include fluorine compound treatment, silica treatment, alumina treatment, aluminum hydroxide treatment, silicone treatment (methicone treatment, hydrogen dimethicone treatment, etc.), silicone resin treatment, pendant treatment, silane coupling agent treatment, titanium coupling agent treatment, silane treatment, oil treatment, surfactant treatment, lecithin treatment, N-acylated lysine treatment, polyacrylic acid treatment, metal soap treatment, acrylic resin treatment, and metal oxide treatment. These surface treatments may be used alone or in combination of two or more.

Additionally, talc, titanium oxide, and zinc oxide powders may be treated with the above-mentioned component (A). In this case, the adhesion of the powder may be further improved. An example of a powder treated with component (A) is titanium oxide treated with sodium dilauroyl glutamate lysine.

The amount of surface treatment agent used is preferably 0.1 to 30% by mass, more preferably 0.5 to 20% by mass, and even more preferably 1 to 10% by mass, relative to the untreated powder.

Conventional surface treatment methods can be used. For example, a surface treatment agent and powder particles to be treated are added to a solvent, stirred using a ball mill or the like, and then dried, washed with water, and filtered repeatedly as needed to remove impurities, followed by drying and pulverization to obtain the desired surface-treated powder. It is also possible to simultaneously treat the surface with several types of surface treatment agent compounds, or to first treat the surface with one compound and then with another compound.

Talc, titanium oxide, and zinc oxide powders may each be coated powders, with one of them acting as the base material (main body) and the other materials coated on that base material. Coating can further suppress the aggregation of the powder. Coating can also increase the adhesiveness of the powder. Furthermore, coating can also improve the functionality of the powder (e.g., usability).

Component (B) talc, titanium oxide, and zinc oxide may be used alone or in combination of two or more. When two or more types of powder are blended, a powder-containing cosmetic composition can be obtained that combines the characteristics of each powder. For example, it can improve makeup effects, UV protection, and usability.

Component (B) is preferably composed of talc and one or more selected from the group consisting of titanium oxide and zinc oxide. That is, it is preferable that the powder of component (B) always contains talc, and component (B) is preferably composed of two types of materials, talc and titanium oxide, two types of materials, talc and zinc oxide, or three types of materials, talc, titanium oxide, and zinc oxide. In this case, it is even easier to obtain a powder-containing cosmetic product with high adhesiveness. Furthermore, from the perspective of improving adhesiveness, it is more preferable that component (B) always contains talc and titanium oxide, and it is even more preferable that component (B) is composed of two types of materials, talc and titanium oxide, or three types of materials, talc, titanium oxide, and zinc oxide.

In this powder-containing cosmetic, the content of component (B) (or the total amount if multiple components are present) is preferably 0.1 to 99% by mass relative to the total amount (100% by mass) of the powder-containing cosmetic. A component (B) content of 0.1% by mass or greater can further enhance the above-mentioned effects of the powder. Furthermore, a component (B) content of 99% by mass or less can easily produce a composition in which the powder is stably formulated. The component (B) content is more preferably 0.5 to 95% by mass, and even more preferably 1 to 90% by mass. In the case of surface-treated powders (talc, titanium oxide, and zinc oxide), the respective contents include the surface-treated components. Similarly, in the case of coated powders (talc, titanium oxide, and zinc oxide), the respective contents include the coating components. However, in the case of powders (talc, titanium oxide, and zinc oxide) treated with component (A), the amount of component (B) is calculated as the amount of the total powder excluding the treated component (A), and the treated component (A) is calculated as the amount of component (A). In other words, the treated component (A) used in powder treatment is not included in the content of component (B), but is included in the content of component (A). The total amount of component (A) in the powder-containing cosmetic is calculated in this way.

Furthermore, with regard to the content of component (B), if talc is included, the content of talc is preferably 1 to 60% by mass, more preferably 2 to 50% by mass, and even more preferably 5 to 40% by mass, relative to the total amount (100% by mass) of the powder-containing cosmetic. Furthermore, if titanium oxide is included, the content of titanium oxide is preferably 1 to 50% by mass, more preferably 2 to 40% by mass, and even more preferably 5 to 30% by mass, relative to the total amount (100% by mass) of the powder-containing cosmetic. Furthermore, if zinc oxide is included, the content of zinc oxide is preferably 1 to 50% by mass, more preferably 2 to 40% by mass, and even more preferably 5 to 30% by mass, relative to the total amount (100% by mass) of the powder-containing cosmetic.

Furthermore, when component (B) contains talc and titanium oxide, the ratio of talc to titanium oxide (talc:titanium oxide) is preferably 1:0.01-100 by mass, more preferably 1:0.05-50, and even more preferably 1:0.1-10. Furthermore, when component (B) contains talc and zinc oxide, the ratio of talc to zinc oxide (talc:zinc oxide) is preferably 1:0.01-100 by mass, more preferably 1:0.05-50, and even more preferably 1:0.1-10.

Here, the ratio of component (A) to component (B) ((A)/(B)) is preferably 0.001 to 0.5 by mass. When the ratio of the content of component (A) to the content of component (B) is within this range, component (A) can bond well to the surface of the powder of component (B), further improving the dispersibility of the powder. From the perspective of obtaining the full effect of the powder and from the perspective of usability, this ratio ((A)/(B)) is preferably 0.001 to 0.3, and more preferably 0.002 to 0.2. As mentioned above, when component (B) treated with component (A) is used, the amount of treated component (A) in the raw material (material) is added to the amount of component (A), and the amount remaining excluding treated component (A) is added to the amount of component (B), and this ratio ((A)/(B)) is calculated.

Ingredient (C)
Component (C) is an oil. The oil is not particularly limited as long as it is an oil commonly used in cosmetics, and various oils, such as liquid, paste, semi-solid, and solid oils, can be used. The oil can improve the adhesion of the powder and the cosmetic durability. It can also improve impact resistance.

Examples of the oil agent of component (C) include natural or synthetic ester oils, hydrocarbon oils, silicone oils, higher alcohols, and fatty acids. One type of oil agent may be used, or two or more types may be used in combination. Preferably, two or more types of oil agents are used.

It is preferable that at least one of the components (C) is an oil agent that is solid or pasty at 25°C. This further improves the powder's adhesion, cosmetic durability, and impact resistance.

Oils that are solid or pasty at 25°C include oils that are solid at 25°C (hereinafter referred to as "oil (C1)") and oils that are pasty at 25°C (hereinafter referred to as "oil (C2)"). In oil (C2), "paste" refers to an amorphous state that is different from a liquid but also different from a solid, i.e., a state intermediate between a solid and a liquid (e.g., a paste, wax, or semi-solid state). For example, a paste state refers to a state in which the viscosity is higher than the upper limit of measurability when measured with a Brookfield viscometer, but it may also be amorphous or fluid. Oils that are pasty at 25°C (C2) can be distinguished from oils that are liquid at 25°C (hereinafter referred to as "oil (C3)") by whether their viscosity can be measured. As the viscosity of a liquid oil increases, it approaches a paste state. In this specification, if the viscosity can be measured, it is considered liquid, and if the viscosity exceeds the measurement limit, it is considered paste. For example, the upper limit of viscosity measurable with a Brookfield viscometer varies depending on the measuring instrument and its manufacturer, but is, for example, 2,000,000 mPa·s. Preferably, oil (C2) has a melting point of 30°C or higher but lower than 61°C. Paste-like is synonymous with semi-solid. Solid means a solid state that lacks fluidity and can be molded into a desired shape. This powder-containing cosmetic may contain an oil (C1) that is solid at 25°C, an oil (C2) that is paste-like at 25°C, or both. Of course, this powder-containing cosmetic may also contain an oil that is liquid at 25°C, and the liquid oil may be used alone or in combination with an oil that is solid or paste-like at 25°C.

Examples of oils (C1) that are solid at 25°C include, but are not limited to, glyceryl stearate, candelilla wax, beeswax, carnauba wax, behenyl alcohol, cetostearyl alcohol, batyl alcohol, stearic acid, palmitic acid, hydrogenated palm oil, diethylaminohydroxybenzoylhexyl benzoate, bisethylhexyloxyphenol methoxyphenyl triazine, and methylenebisbenzotriazolyltetramethylbutylphenol. These may be used alone or in combination of two or more.

Examples of oils (C2) that are paste-like at 25°C include, but are not limited to, di(octyldodecyl/phytosteryl/behenyl) lauroyl glutamate, di(cholesteryl/behenyl/octyldodecyl) lauroyl glutamate, phytosteryl/isostearyl/cetyl/stearyl/behenyl dimer dilinoleate, phytosteryl isostearate, phytosteryl oleate, dipentaerythrityl hexa(hydroxystearate/hexastearic acid/hexarosinate), petrolatum, hydrogenated castor oil stearate, cholesteryl hydroxystearate, polyhydroxystearic acid, shea butter, hydrogenated coconut oil, hydrogenated polyisobutene (paste-like at 25°C), and rice bran oil fatty acid phytosteryl. These may be used alone or in combination of two or more.

Examples of oils (C3) that are liquid at 25°C include, but are not limited to, liquid paraffin (also known as mineral oil), light liquid isoparaffin, PG dicaprate, cetyl 2-ethylhexanoate, glyceryl tri-2-ethylhexanoate, isotridecyl isononanoate, isononyl isononanoate, ethyl oleate, di-2-ethylhexyl succinate, ethylhexyl methoxycinnamate, isopropyl myristate, isopropyl palmitate, squalane, octyldodecanol, caprylic/capric triglyceride, trimethylolpropane triisostearate, pentaerythritol tetraisostearate, isohexadecane, isododecane, undecane, tridecane, jojoba oil, macadamia Examples of suitable ingredients include tallow oil, meadowfoam oil, olive oil, isostearic acid, dimethicone, methylphenylpolysiloxane, diphenylsiloxyphenyl trimethicone, tritridecyl trimellitate, ascorbyl tetrahexyldecanoate, pentaerythristyl tetraethylhexanoate, polyglyceryl-2 diisostearate, sorbitan sesquiisostearate, propylene glycol dicaprate, tocopherol, diisostearyl malate, highly polymerized dimethylpolysiloxane (1 million CS), polyglyceryl monoisostearate, dipentaerythrityl tri-polyhydroxystearate, hydrogenated polyisobutene, polysilicone-15, and di(phytosteryl/octyldodecyl) lauroyl glutamate. These may be used alone or in combination of two or more.

When multiple oils are included, the content of component (C) refers to the total amount. As mentioned above, the content of component (C) (or the total amount when multiple oils are included) is preferably 1% by mass or more relative to the total amount of the powder-containing cosmetic (100% by mass). This improves the powder's adhesion, cosmetic durability, and impact resistance. The content of component (C) is preferably 3% by mass or more, and more preferably 5% by mass or more. The upper limit of the content of component (C) is not particularly limited, but may be, for example, 50% by mass or less, preferably 40% by mass or less, and more preferably 30% by mass or less, so that the powder's functions can be fully exerted. From the above perspectives, the content of component (C) is preferably 1 to 50% by mass, more preferably 3 to 40% by mass, and even more preferably 5 to 30% by mass, relative to the total amount of the powder-containing cosmetic.

Furthermore, when the powder-containing cosmetic contains an oil agent that is solid or pasty at 25°C, the content of the solid or pasty oil agents at 25°C (the total amount if there are multiple solid or pasty oil agents) is preferably 0.001 to 20% by mass, more preferably 0.1 to 10% by mass, even more preferably 0.3 to 5% by mass, and even more preferably 0.5 to 5% by mass, relative to the total amount of the powder-containing cosmetic.

Ingredient (D)
Component (D) is a polysaccharide. The polysaccharide is not particularly limited as long as it is a polysaccharide commonly used in cosmetics, and various natural or synthetic polysaccharides can be used. In the present powder-containing cosmetic, the incorporation of polysaccharides significantly suppresses powder aggregation. Furthermore, polysaccharides can also improve impact resistance. As described above, in conventional powder-containing cosmetics, powders with good adhesion (particularly talc, titanium oxide, and zinc oxide) have been incorporated. Furthermore, the incorporation of surfactants and oils to enhance adhesion has made aggregation more likely to occur. Therefore, it has been extremely difficult to achieve both improved adhesion to the skin and suppression of powder aggregation. However, the present invention has discovered that the incorporation of polysaccharides makes it possible to obtain powder-containing cosmetics that have excellent adhesion to the skin, excellent powder dispersibility (agglomeration suppression), long-lasting makeup, and a smooth feel when used.

Polysaccharides are typically polymers formed by the polymerization of sugar molecules. Natural polysaccharides are preferred because they are readily available. Natural polysaccharides are derived from plants (seeds, sap, fruits, etc.), seaweed, and microorganisms, and any of these may be used. Polysaccharides may also be natural polysaccharides that have been treated (e.g., hydrogenated, alkylated, such as methylated). Polysaccharides that are commercially available as cosmetic ingredients can be used, and these may be in solid or liquid form at 25°C. It is particularly preferred that the polysaccharide be in a solid state, especially in powder form.

Component (D) is preferably a polysaccharide that is powdery at 25°C. When the polysaccharide component (D) is powder, it can further inhibit powder aggregation. The mechanism by which powder aggregation is inhibited is thought to be that the polysaccharide, which is a polymer (high molecular weight), interacts with the surface of the powder, creating steric hindrance and inhibiting aggregation, or that another powder is inserted between the powders to inhibit powder aggregation, but this mechanism is not limited to these. Note that "powdered" refers to the form of the polysaccharide component (D) prior to the production stage of the powder-containing cosmetic; it does not have to be in powder form in the powder-containing cosmetic after production.

Polysaccharides include gums and celluloses, such as xanthan gum, carrageenan, gellan gum, hydroxypropyl methylcellulose, methylcellulose, sodium hyaluronate, sodium acetyl hyaluronate, glycosyl trehalose/hydrolyzed starch mixed solution, agar, tamarind seed gum, locust bean gum, gum arabic, and guar gum. These may be used alone or in combination of two or more. Among the polysaccharides listed above, those that are powdery at 25°C are preferred, as this further suppresses powder aggregation. In this specification, a polysaccharide (e.g., xanthan gum) swollen with water or the like (raw material) is classified as a powdered polysaccharide if the pure content before swelling is a solid powder. Furthermore, in this specification, polysaccharides produced in a liquid state are classified as liquid polysaccharides, such as a glycosyltrehalose/hydrogenated starch hydrolysate mixed aqueous solution, which is obtained by enzymatically reacting and hydrogenating corn starch. However, because the raw material for the polysaccharide is obtained in liquid form (without going through a solid state), it is classified as a liquid polysaccharide.

It is preferable that at least one of the components (D) is selected from the group consisting of xanthan gum, carrageenan, gellan gum, and hydroxypropyl methylcellulose. This makes it possible to more effectively suppress powder aggregation.

In this powder-containing cosmetic, the content of component (D) (or the total amount if multiple components are present) is preferably 0.0001 to 10% by mass relative to the total amount (100% by mass) of the powder-containing cosmetic. Having the content of component (D) within this range further enhances the effects of the polysaccharide. The content of component (D) is more preferably 0.005 to 0.5% by mass, and even more preferably 0.001 to 1% by mass. For polysaccharides (e.g., xanthan gum) swollen with water or the like (raw material), the polysaccharide content is the pure content (solid content). For polysaccharides produced in a liquid state (e.g., a mixed aqueous solution of glycosyl trehalose and hydrogenated starch hydrolysate), the polysaccharide content is the total amount. Furthermore, polysaccharides produced in a liquid state may become solid when dried, and the solid content (the percentage ratio of the mass of the solid after drying to the mass of the liquid state before drying) may be, for example, 10 to 80% by mass.

Here, the ratio of component (A) to component (D) ((A)/(D)) is preferably 1 to 1000 by mass. When the ratio of the content of component (A) to the content of component (D) is within this range, powder aggregation can be more effectively suppressed, further improving the dispersibility of the powder. From the viewpoint of suppressing powder aggregation, the ratio of component (A) to component (D) ((A)/(D)) is preferably 3 to 700 by mass, and more preferably 5 to 500.

Component (E)
The powder-containing cosmetic preferably further contains, as component (E), a monohydric or dihydric alcohol that is liquid at 25°C. Component (E) is a monohydric alcohol that is liquid at 25°C or a dihydric alcohol that is liquid at 25°C. By incorporating a monohydric or dihydric alcohol that is liquid at 25°C, components (A) to (D) can be stably incorporated, powder aggregation can be further suppressed, and powder adhesion can be further improved. The liquid monohydric or dihydric alcohol is preferably water-soluble. In this specification, the water-solubility of the alcohol may be, for example, that which dissolves in water at a concentration of 1% by mass, preferably 5%, 10%, 30%, or 50% (all by mass), and more preferably that which is miscible with water in any ratio. The monohydric or dihydric alcohol may be an alcohol having a carbon number of preferably 1 to 12, more preferably 1 to 8, and even more preferably 2 to 6.

Examples of monohydric alcohols that are liquid at 25°C include, but are not limited to, ethanol, methanol, propanol, isopropanol, and phenoxyethanol. Ethanol is a more preferred monohydric alcohol. Examples of liquid dihydric alcohols include, but are not limited to, 1,3-butylene glycol, dipropylene glycol, tripropylene glycol, and ethylhexylglycerin. Component (E) is preferably one or more selected from the group consisting of 1,3-butylene glycol, dipropylene glycol, and ethanol. Liquid monohydric or dihydric alcohols may be used alone or in combination of two or more.

The content of component (E) (the total amount if multiple components are present) is not limited to the above, but from the perspective of achieving both powder adhesion and dispersibility, it is preferably 0.1 to 20% by mass, more preferably 0.5 to 10% by mass, and even more preferably 1 to 5% by mass, relative to the total amount of the powder-containing cosmetic (100% by mass).

Powder (powder other than component (B))
The present powder-containing cosmetic may contain powders other than component (B). The incorporation of powders can further impart effects such as makeup effects, UV scattering effects, and improved usability.

The powder is not particularly limited in terms of shape (e.g., spherical, plate-like, spindle-like, needle-like, etc.), particle size (e.g., mist-like, fine particles, pigment-grade, etc.), particle structure (e.g., porous, non-porous, etc.), etc. Examples of powders include inorganic powders, glitter powders, organic powders, colored pigments, and composite powders.

Inorganic powders may include, but are not limited to, metal oxide powders, metal carbonate powders, metal silicate powders, etc. Specific examples of inorganic powders include aluminum oxide, cerium oxide, magnesium oxide, zirconium oxide, iron oxide, mica, synthetic mica, sericite, synthetic sericite, carbon black, magnesium carbonate, calcium carbonate, chromium oxide, chromium hydroxide, aluminum silicate, magnesium silicate, magnesium aluminum silicate, (fluoride/hydroxide/oxide)/(Mg/K silicon) (calcined talc-potassium silicofluoride), kaolin, silicon carbide, barium sulfate, boron nitride, silica, glass powder, and borosilicate.

Glittering powders may include, but are not limited to, chemically treated mica. Specific examples of luminous powders include bismuth oxychloride, titanium mica (titanium oxide-coated mica), iron oxide-treated mica, iron oxide-treated titanium mica, organic pigment-treated titanium mica, silicon dioxide/titanium oxide-coated mica, titanium oxide-coated glass powder, iron oxide/titanium oxide-coated glass powder, and aluminum powder. In this specification, powders other than component (B) that have been treated with component (B), such as titanium oxide-treated powder, are not included in component (B) because the main body of the powder is not component (B).

Examples of organic powders include metal soap powders such as zinc laurate, zinc myristate, zinc stearate, magnesium laurate, magnesium myristate, magnesium stearate, and aluminum stearate; N-acyl lysine, nylon, polymethylsilsesquioxane, crosslinked organopolysiloxane polymers, polystyrene, polyurethane, polyethylene, polypropylene, polyethylene terephthalate, polymethacrylates such as polymethyl methacrylate, and crosslinked polymethacrylates such as methyl methacrylate crosspolymers; complexes of polymethyl methacrylate and polyisoprene; polyacrylic esters; acrylonitrile-methacrylic acid copolymer powders; polytetrafluoroethylene; and (HDI/PPG/polycaprolactone) crosspolymers. Examples of crosslinked organopolysiloxane polymers include partially crosslinked methylpolysiloxanes such as (dimethicone/vinyldimethicone) crosspolymer, partially crosslinked methylphenylpolysiloxanes such as (dimethicone/phenyldimethicone) crosspolymer, partially crosslinked polyether-modified silicones such as dimethicone copolyol crosspolymer, partially crosslinked alkyl-modified silicones, and partially crosslinked alkyl-polyether-modified silicones such as (lauryldimethicone-PEG) crosspolymer. Examples of these crosslinked organopolysiloxane polymers, by INCI name, include (dimethicone/vinyldimethicone) crosspolymer, (dimethicone/phenylvinyldimethicone) crosspolymer, (dimethicone/vinyldiphenyldimethicone/methicone) crosspolymer, (dimethicone/lauryldimethicone) crosspolymer, (diphenyldimethicone/vinyldiphenyldimethicone/silsesquioxane) crosspolymer, and (vinyldimethicone/methicone silsesquioxane) crosspolymer.

Other Components In addition to the above components, the present powder-containing cosmetic may contain appropriate components commonly used in powder cosmetics, such as surfactants, water, preservatives, antioxidants, cosmetic ingredients, antibacterial agents, chelating agents (such as EDTA), etc., within a range that does not impair the effects of the present invention.

Solid Powder Cosmetics Powder-containing cosmetics are preferably solid cosmetics. Solid cosmetics containing powder are referred to as solid powder cosmetics. In this specification, solid powder cosmetics refer to cosmetics that contain powder and have been molded into a solid form. Therefore, fluid liquid cosmetics are not included in solid powder cosmetics. However, moist semi-solid cosmetics (e.g., semi-paste, wax-like) are also included in solid powder cosmetics as long as they have the same moldability as solid state cosmetics. Solid powder cosmetics may be in a unified solid form. It is important that solid powder cosmetics are impact resistant and resistant to cracks, chips, and cracks. However, the use of the above-mentioned ingredients in solid powder cosmetics makes them highly impact resistant and prevents cracks, chips, and cracks. Powder-containing cosmetics may of course be in forms other than solid powder cosmetics (e.g., oil-in-water emulsions, water-in-oil emulsions, powder dispersion suspensions, powder dispersion pastes, powder cosmetics, etc.).

The present powder-containing cosmetic may be a skin cosmetic or a hair cosmetic. It is particularly preferable that the present powder-containing cosmetic is a skin cosmetic (a powder-containing cosmetic for the skin). Furthermore, the present powder-containing cosmetic can be used in any cosmetic product containing powder for any purpose, including skin care products and makeup products.

Skin cosmetics are not particularly limited, and can be used as powder-containing cosmetics (especially solid powder cosmetics) for a variety of purposes. Examples include makeup cosmetics, foundations (e.g., solid foundations, oil-based solid foundations), blushers, eye shadows, eye colors, concealers, powders, lipsticks, makeup bases, sunscreens, skin care cosmetics, emulsions (e.g., solid emulsions), and creams (e.g., solid creams). Methods of using skin cosmetics include applying them to the hands or fingers, using cotton, and directly applying solid cosmetics.

Production of Powder-Containing Cosmetic The above-mentioned powder-containing cosmetic can be produced by mixing the above-mentioned components. For example, the powder-containing cosmetic can be obtained by mixing components (A) to (D), component (E), and other components including other powders, and molding the mixture in a molding machine. The molded solid powder-containing cosmetic becomes a solid powder cosmetic.

This powder-containing cosmetic can preferably be produced by a method including the steps of preparing a mixture slurry by mixing components (A) to (D) and an aqueous solvent, molding the mixture slurry, and removing the aqueous solvent from the mixture slurry. This allows for the production of a powder-containing cosmetic in which the powder is well dispersed and is less likely to aggregate. It also allows for the production of a powder-containing cosmetic (solid powder cosmetic) with high impact resistance. If component (E) and other components are used, these components can also be mixed when components (A) to (D) are mixed.

To prepare the mixture slurry, first, the raw ingredients of the powder-containing cosmetic (components (A) to (D) and other ingredients including component (E) and other powders) and an aqueous solvent are mixed to prepare a mixture slurry. Preferably, the raw ingredients of the powder-containing cosmetic are mixed, the mixture is pulverized, and then the aqueous solvent is added to the pulverized powder mixture. This further improves the dispersibility of the powder. The raw ingredients of the powder-containing cosmetic are dispersed in the aqueous solvent, forming a mixture in the form of a slurry. Component (C) is preferably heated and mixed. This allows component (C) to be more dispersed and mixed, thereby improving the dispersibility and adhesion of the powder due to component (C).

From the perspective of removal after molding, the aqueous solvent is preferably a volatile solvent (water or organic solvent). Water is particularly preferred as an aqueous solvent. Water may be purified water. Other aqueous solvents include, but are not limited to, alcohols and ketones. Specific examples include methanol, ethanol, propanol, and acetone. A single aqueous solvent may be used, or two or more may be used in combination. For example, a mixed solvent of water and ethanol may be used as the aqueous solvent. The amount of aqueous solvent is preferably a mass ratio (aqueous solvent:raw material components) of 0.3 to 10:1, more preferably 0.3 to 5:1, and even more preferably 0.5 to 3:1, relative to the total amount of raw material components of the powder-containing cosmetic. This further improves the dispersibility of the powder.

The mixture slurry may or may not be heated and mixed. The mixture slurry may also be heated to room temperature or higher by mixing with a mixer. This disperses the powder-containing ingredients, allowing for the production of a powder-containing cosmetic product with good dispersibility. The temperature during mixing may be, for example, 20 to 70°C, or even 20 to 40°C.

Next, the mixture slurry is molded. The mixture slurry can be molded using an appropriate molding machine capable of molding powder-containing cosmetics. Alternatively, the mixture slurry may be filled into a cosmetic container and molded. Because the mixture slurry has fluidity, it can be easily filled into a container. The mixture slurry may also be filled in a heated state.

Then, after molding the mixture slurry, the aqueous solvent is removed. If the aqueous solvent is volatile, it can be easily removed by heating. The heating temperature is preferably 30 to 90°C, and more preferably 30 to 60°C. After the aqueous solvent has been removed by heating, the molded product can be cooled to obtain the final powder-containing cosmetic product (solid powder cosmetic product). If the mixture is filled into a container and molded, a solid powder cosmetic product filled into the container can be obtained.

Powder-containing cosmetics obtained by the above manufacturing method have better powder dispersibility and are less likely to aggregate than powder-containing cosmetics produced by mixing the same raw ingredients without using an aqueous solvent. They may also have improved impact resistance when solidified. It is difficult, impossible, or even impractical to explain these differences solely in terms of the composition of the ingredients. Therefore, this specification discloses an invention for a powder-containing cosmetic obtained by mixing components (A) to (D) and an aqueous solvent to prepare a mixture slurry, molding the mixture slurry, and then removing the aqueous solvent.

The powder-containing cosmetic preparation according to the present invention will be explained below using examples, but the present invention is not limited to these examples.

Synthesis of PC Compound and NMR Measurement The PC compound of component (A2) was synthesized according to the following synthesis example. The obtained PC compound was dissolved in deuterated chloroform containing tetramethylsilane (TMS) as an internal standard, and then the compound was analyzed using JNM-AL600 (manufactured by JEOL Ltd.).

Synthesis Example 1 (Synthesis of PC Compound 1)
A combination of (R ¹ , R ² , R ³ , R ⁴ ) = (oleyl group, hydroxyethyl group, hydroxyethyl group, behenyl group) 65.3 g (0.2 mol) of behenyl alcohol as the raw material alcohol, 20.2 g (0.2 mol) of triethylamine, and 280 g of tetrahydrofuran were added to a 1 L round flask equipped with a thermometer, a dropping funnel, and a stirrer, and the mixture was cooled to 4°C and stirred and mixed. Next, a mixed solution of 28.5 g (0.2 mol) of 2-chloro-2-oxo-1,3,2-dioxaphosphorane and 60 g of tetrahydrofuran was added dropwise to the cooled mixed solution using the dropping funnel. The dropwise addition was carried out gradually over 2 hours while stirring the cooled mixed solution and ensuring that the reaction temperature did not exceed 10°C. After the dropwise addition was completed, stirring was continued for another 1 hour. Subsequently, triethylamine hydrochloride, which precipitated as a by-product, was filtered off. The entire amount of the obtained filtrate was placed in a 2 L round-bottom flask equipped with a stirrer, and 142 g (0.4 mol) of N,N-diethanololeylamine as a tertiary amine and 380 g of acetonitrile were added, followed by stirring at 70°C for 12 hours. The reaction solution was then cooled to obtain a precipitate, which was filtered off and dried under reduced pressure at 70°C to obtain crude crystals. The obtained crude crystals were recrystallized from a mixed solvent of tetrahydrofuran and acetonitrile to obtain 15.7 g of white crystals (yield 10%).
