JP7779662B2 - Solid powder cosmetics - Google Patents

Description

The present invention relates to a solid powder cosmetic.

Powder cosmetics, which are cosmetics blended with powder, are widely used as makeup cosmetics such as foundation, face powder, blush, eye shadow, and eyebrow makeup. Among these, many solid powder cosmetics, which are molded into a solid form for portability and texture, are on the market.

Methods for molding solid powder cosmetics include dry molding, in which a powdered composition is filled into a container such as a metal dish and then pressurized, and wet molding, in which a solvent such as a volatile compound is added to a cosmetic base containing powder and oil to form a slurry, which is then filled into a container such as a metal dish and the solvent is then removed and molded. Solid powder cosmetics obtained using wet molding have a smooth feel when used because the powder is arranged in an orderly manner to achieve a higher density when the solvent is removed from the slurried cosmetic base. However, when the solvent used in wet molding is removed, cracks can occur on the surface, or gaps can form between the container and the powder cosmetic due to shrinkage, resulting in poor impact resistance.

Various means have been proposed to improve this impact resistance. Patent Document 1 discloses a solid powder cosmetic obtained by wet molding a cosmetic base containing fluorine-treated talc, hydrophobically treated silica, hydrophobically treated fine particle titanium dioxide, and a water-holding oil agent.

Japanese Patent Application Laid-Open No. 2018-177640

Various studies have been conducted to date on improving the impact resistance of solid powder cosmetics obtained by wet molding as described above. However, attempts to improve impact resistance usually result in the cosmetics becoming harder, which makes it difficult for the cosmetics to be removed when the user tries to take the solid powder cosmetics with their fingers or an applicator (poor cosmetic transfer), making it difficult to adhere an appropriate amount of cosmetics to the fingers or applicator.

Furthermore, after applying solid powder cosmetics to the skin, the powder adheres to the skin, forming a cosmetic film and achieving the cosmetic effects of the powder. Therefore, for solid powder cosmetics, adhesion of the cosmetic to the skin (excellent adhesion) is extremely important for achieving the cosmetic effects. Furthermore, the ability to maintain the cosmetic film formed by the adhered cosmetic for an extended period of time is a fundamental performance feature, and users are constantly seeking improvements in this performance.

However, solid powder cosmetics obtained by wet molding have not been satisfactory in terms of achieving both improved impact resistance and a good feel when used (particularly the texture of the solid powder cosmetics, the adhesion of the solid powder cosmetics, and the durability of the cosmetic effect).

The object of the present invention is therefore to provide a solid powder cosmetic that has good transferability to an applicator, strong adhesion to the skin, long-lasting cosmetic effects, and excellent impact resistance.

The present invention relates to a composition comprising the following components (A) to (E):
(A) Fluorine-modified silicone oil (B) Silicone wax (C) Silicone oil (excluding components (A) and (B))
(D) A solid powder cosmetic is obtained by removing the solvent from a mixture of a cosmetic base containing a compound (E) powder having a hydrophilic group and a lipophilic group in one molecule, and the lipophilic group being of a double-chain type.

The solid powder cosmetic of the present invention exhibits good adhesion to applicators, strong adhesion to the skin, long-lasting cosmetic effects, and excellent impact resistance.

Embodiments of the present invention are described below. However, the present invention is not limited to the following embodiments. In this specification, the range "X to Y" includes X and Y and means "X or more and Y or less." Unless otherwise specified, operations and measurements of physical properties are performed at room temperature (20-25°C) and a relative humidity of 45-55% RH.

The first embodiment of the present invention is a composition comprising the following components (A) to (E):
(A) Fluorine-modified silicone oil (B) Silicone wax (C) Silicone oil (excluding components (A) and (B))
The solid powder cosmetic is obtained by removing the solvent from a mixture of a cosmetic base containing a powder of a compound (D) having a hydrophilic group and a lipophilic group in one molecule, the lipophilic group being of a double-chain structure (E). The solid powder cosmetic of the first embodiment exhibits good adhesion to an applicator, high adhesion of the cosmetic to the skin, long-lasting cosmetic effects, and excellent impact resistance (suppression of cracking and shrinkage after solvent removal).

The detailed mechanism by which the cosmetic composition of this embodiment achieves the above-mentioned effects is unknown, but is thought to be as follows. Note that the following mechanism does not in any way limit the technical scope of the present invention.

In the wet molding method, a slurry-like composition is used, the viscosity of which is reduced using a solvent when the composition is filled into a container. The solvent is ultimately removed by absorption into an absorbent pad or drying. The inventors noted that if the solvent is difficult to remove from the slurry-like composition, it can lead to shrinkage and cracking of the final solid powder cosmetic. The use of oils (A) to (C) and component (D) reduces the compatibility between the solvent and the composition, improving solvent removal and thus improving the impact resistance of the final solid powder cosmetic. In particular, component (A) is fluorine-modified to be water- and oil-repellent, which reduces its compatibility with hydrocarbon oils and water, which are commonly used as solvents, and significantly improves solvent removal. However, for component (A) to exert its effects, it is important to combine it with silicone oil (see Comparative Example 6 below). This is thought to be because the silicone oil of component (C) is necessary for component (A) to be uniformly dispersed within the formulation. Furthermore, because solvent removal is good, impact resistance is improved, and there is no particular need to increase the hardness of the formulation, such as by increasing the pressing pressure during production. Therefore, it is thought that the resulting solid powder cosmetic will not harden and that the cosmetic will have good toning. With regard to the toning of the cosmetic, components (B) and (D) also play important roles, and the incorporation of components (B) and (D) improves the toning of the cosmetic. This is because components (B) and (D) can improve the binding between powder particles, ensuring strength without the need for high pressing pressure during production, and it is thought that the resulting solid powder cosmetic will not harden and that the cosmetic will have good toning.

Furthermore, by using component (B), which is highly compatible with components (A) and (C), the wax is dispersed evenly around the powder, which is thought to improve the durability of the cosmetic effect. Furthermore, component (D) not only has high adhesion to the powder as mentioned above, but also has good compatibility with the oils in components (A) to (C) and has high adhesion to the skin, so it is thought to play an important role in forming and maintaining a uniform cosmetic film.

In this specification, the term "solid powder cosmetic" refers to a solid cosmetic whose main ingredient is powder. Here, "main ingredient" refers to a cosmetic containing 50% or more by mass of powder. In this embodiment, the powder content is preferably greater than 60% by mass, more preferably 70% or more by mass, and even more preferably 80% or more by mass. The upper limit for the powder content is 100% by mass, but taking into account other ingredients blended into the cosmetic, it is typically 99.9% by mass or less, and may be 99.5% by mass or less, or even 99% by mass or less.

Component (D) is a compound having a hydrophilic group and a lipophilic group in one molecule, and the lipophilic group is a two-chain type. By having the hydrophilic group and the lipophilic group, it is possible to interact with the powder regardless of whether or not the surface treatment of component (E) is performed, and it is thought that the bonding strength between the powders is improved. In addition, since the lipophilic group is a two-chain type, it is possible to further increase the bonding strength between the powders compared to a single-chain type, and at the same time, it is thought that the lipophilic chain is oriented in a certain direction, thereby improving the function.

Examples of component (D) include phospholipids, N-acylamino acids or salts thereof, and behendimonium ethyl stearyl phosphate, double-chain biscarboxylate-type amphiphilic compounds (commercially available products include, for example, Gemisurf α142 (a dicarboxylic acid having two lauryl groups), manufactured by Chukyo Yushi Co., Ltd.), and bispyridimonium quaternary ammonium salt-type amphiphilic compounds (commercially available products include, for example, Hygenia S-100 (3,3'-(butane-1,4-dioxydimethylene)-N,N-didecyldipyridinium dibromide), manufactured by Tama Chemical Industry Co., Ltd.).

Among these, from the standpoint of improving impact resistance and prolonging the duration of cosmetic effects, it is preferable that component (D) be at least one selected from the group consisting of phospholipids, N-acylamino acids or salts thereof, and behendimonium ethyl stearyl phosphate.

Phospholipids can generally be classified into two types: glycerophospholipids with a glycerin backbone and sphingophospholipids with a sphingosine backbone. Phospholipids as component (D) include glycerophospholipids and sphingophospholipids.

N-acylamino acids are amino acids in which at least one of the amino groups is acylated with an acyl group. In this specification, N-acylamino acids or salts thereof may also be referred to as N-acylamino acids (salts).

The acyl group is preferably a saturated or unsaturated, linear, branched, or cyclic acyl group having 6 to 30 carbon atoms, more preferably a saturated or unsaturated, linear or branched acyl group having 8 to 20 carbon atoms, and even more preferably a saturated linear acyl group having 12 to 18 carbon atoms.

Examples of acyl groups include lauroyl, myristoyl, palmitoyl, stearoyl, isostearoyl, and oleoyl groups.

Salts include salts with sodium, potassium, magnesium, calcium, aluminum, zinc, monoethanolamine, diethanolamine, triethanolamine, etc., with sodium, magnesium, calcium, and triethanolamine being preferred, sodium and magnesium being more preferred, and sodium being even more preferred.

N-acylamino acids (salts) that can be used as component (D) are not particularly limited, but specific examples include lysine dilauroyl glutamate and sodium dilauroyl glutamate lysine.

Behendimonium ethyl stearyl phosphate is a compound having the following structure:

Behendimonium ethyl stearyl phosphate is a phospholipid-like compound in which a nitrogen-containing alcohol is added to a phosphate ester. Because of this structure, it has extremely high affinity for the skin, while its relatively small molecular weight allows it to interact with powder and easily bond to the powder surface, which is thought to help the powder adhere evenly to the skin. Therefore, by incorporating behendimonium ethyl stearyl phosphate into solid powder cosmetics, the powder adheres more easily to the skin (it is easier to form a cosmetic film). Furthermore, behendimonium ethyl stearyl phosphate has a good balance of lipophilicity and hydrophilicity, and is excellent in water and oil repellency, which can provide benefits such as improved makeup staying power.

Component (D) may be used alone or in combination of two or more types.

Taking into consideration adhesion to the skin, the content of component (D) in the solid powder cosmetic is preferably 0.05% by mass or more, more preferably 0.1% by mass or more, and even more preferably 0.3% by mass or more. Furthermore, taking into consideration impact resistance, the content of component (D) is preferably 5% by mass or less, more preferably 3% by mass or less, and particularly preferably 2.5% by mass or less. A preferred embodiment of the present invention is a content of 0.05 to 5% by mass in the solid powder cosmetic.

Component (D) may also be used as a surface treatment agent for component (E) powder. In this case, the content of component (D) does not count as the content of component (E).

Component (D) can be surface-treated onto component (E) using conventional methods. For example, component (D) and the powder to be treated are added to a solvent (e.g., an alcohol such as isopropyl alcohol (IPA) or isoparaffin (e.g., IP Solvent (Idemitsu Kosan)) and stirred in a ball mill or the like. The resulting mixture is then dried, washed with water, and filtered as needed to remove impurities, followed by drying and pulverization to obtain the desired surface-treated powder. Component (D) and another surface-treating compound may also be used for surface treatment simultaneously.

(Other ingredients)
In addition to the above components, oils other than components (A) to (C), alcohols, preservatives, antioxidants, cosmetic ingredients, antibacterial agents, fragrances, chelating agents (such as EDTA), UV absorbers, film-forming agents, fragrances, and the like, which are commonly used in cosmetics, may also be appropriately contained within a range that does not impair the effects of the present invention. In consideration of the effects of the present invention, it is preferable that the amount of oils other than components (A) to (C) be as small as possible, and specifically, the amount of oils other than components (A) to (C) relative to the total amount of oils is preferably 30% by mass or less, more preferably 25% by mass or less, and even more preferably 20% by mass or less.

Furthermore, in the solid powder cosmetic of the present application, the water content is preferably 3% by mass or less, more preferably 1% by mass or less, and preferably substantially free of water. Here, "substantially free of water" means that the presence of impurities is acceptable, and refers to, for example, 0.1% by mass or less.

The solid powder cosmetic of this embodiment is obtained by removing the solvent from a mixture of a cosmetic base containing components (A) to (E) and a solvent.

The cosmetic base is prepared by stirring and mixing the above ingredients using equipment typically used to produce powder cosmetics. More specifically, the cosmetic base is prepared by first mixing oily ingredients containing components (A) to (C), or optionally component (D), and dissolving them by heating, if necessary. Meanwhile, a powder containing component (E) and, optionally, a powder surface-treated with component (D) are mixed uniformly. The oily ingredients are added to this mixture, dispersed uniformly, and then pulverized to prepare the cosmetic base.

Next, a mixture of the cosmetic base and solvent is prepared. This mixture is usually in a slurry state. Hereinafter, the mixture of the cosmetic base containing components (A) to (E) and the solvent will also be referred to simply as the "mixture."

The solvent used can be either non-volatile or volatile, but a solvent with a boiling point of 260°C or less at normal pressure is preferred. Specific examples of solvents include aqueous solvents such as low-boiling alcohols such as water, ethyl alcohol, propyl alcohol, isopropyl alcohol, and butyl alcohol, and mixed solvents of water and low-boiling alcohols; and oil-based solvents such as (low-boiling) hydrocarbon oils such as isododecane, isohexadecane, and light liquid isoparaffin. These can be used alone or in combination as a mixture of two or more.

The solvent is preferably a hydrocarbon oil or an aqueous solvent, as this makes it easier to achieve the effects of the present invention, and more preferably a low-boiling hydrocarbon oil such as isododecane, isohexadecane, or light liquid isoparaffin (hydrogenated polyisobutene).

The amount of solvent to be mixed can be selected arbitrarily to provide fluidity for filling the pre-molded mixture into a container or tray, but it is preferable to use 10 to 200 parts by weight of solvent per 100 parts by weight of cosmetic base. This range ensures good solvent removal.

In addition, in this specification, fluidity refers to a state in which, when 30 g of a mixture of a cosmetic base whose main ingredient is powder and a solvent is placed in a container ("Pill Bottle PS-6K" manufactured by Daiichi Glass Co., Ltd.) with an inner diameter of 2.47 cm, a body diameter of 4.05 cm, and an overall height of 7.4 cm, the container is stopped up with the attached lid, and the container is tilted 90 degrees in an environment of 25°C and 1 atmosphere and left to stand for 1 minute, and some of the mixture adheres to the inside of the lid.

The mixture obtained above is then filled into a container. Examples of containers include metal dishes, resin dishes, etc. After filling, it is preferable to perform compression molding.

Next, the solvent is removed. While there are no particular limitations on the method of removal, it is preferable to remove the solvent by placing one or more layers of paper, cloth, or the like in contact with the powder cosmetic filled in the container during and/or after compression molding, and allowing the solvent to be absorbed. Moderate pressure may be applied when absorbing the solvent. Furthermore, when filling a container or inner tray with a mixture of cosmetic base and solvent, it is preferable to lightly press the mixture using a pad or the like to smooth the surface. During this pressing, a porous press head or absorbent may also be used to absorb the volatile solvent. Furthermore, the solvent can also be removed by drying. The conditions for this are appropriately set depending on the boiling point and specific heat of the solvent; for example, in the case of light liquid isoparaffin, drying is performed at 50-80°C for approximately 5-20 hours.

The solid powder cosmetic of this embodiment can be used in makeup cosmetics such as foundation, face powder, face powder, concealer, eye color (eye shadow), eyeliner, eyebrow pencil, mascara, blush, lipstick, sunscreen cosmetics, and makeup base; skin care cosmetics such as body powder; and more. Preferably, the cosmetic is a makeup cosmetic such as foundation, face powder, face powder, eye color, makeup base, sunscreen cosmetics, or blush, which is expected to further exhibit the effects of the present application, and more preferably a foundation, face powder, or face powder, which has a large application area. Furthermore, the cosmetic can be used by applying it with the hands or fingers, or by impregnating a puff, sponge, or the like with the cosmetic.

The amount of each ingredient in the cosmetic base will be the same as the amount of each ingredient in the resulting solid powder cosmetic.

The effects of the present invention will be explained using the following examples and comparative examples. In the examples, the terms "parts" and "%" may be used, but unless otherwise specified, they represent "parts by mass" or "% by mass." Furthermore, unless otherwise specified, all operations are performed at room temperature (25°C).
