Description

The present invention relates to a water-in-oil emulsion cosmetic containing an ultraviolet absorber and a metal oxide. The present invention also relates to a method for producing a water-in-oil emulsion cosmetic containing an ultraviolet absorber and a metal oxide.

Water-in-oil (W/O) emulsion cosmetics are known as one type of emulsion used in cosmetics. For water-in-oil emulsion cosmetics, the stability of the formulation over time (e.g., emulsion stability and aggregation inhibition) and the feel upon application (e.g., smoothness, non-stickiness, adhesion to skin, etc.) are important, but when UV absorbers and metal oxides are combined, it is not easy to satisfy all of these requirements. For example, the technologies described in Patent Documents 1 and 2 below are known as examples of water-in-oil emulsion cosmetics.

Patent Document 1 discloses a water-in-oil emulsion cosmetic that combines a hydrophobically treated metal oxide with polyhydroxystearic acid, a volatile hydrocarbon oil, and the like. However, when an ultraviolet absorber is added to the cosmetic of Patent Document 1, the smooth feel during use is likely to be impaired and emulsion stability may be reduced. Furthermore, Patent Document 2 discloses a water-in-oil sunscreen cosmetic that combines a specific solid ultraviolet absorber with a specific polar oil, a volatile hydrocarbon oil, and the like. However, when a metal oxide is added to the cosmetic of Patent Document 2, the dispersibility of the metal oxide is likely to be poor, and the smooth feel during use is likely to be impaired due to powdery texture.

(F) a metal oxide,
The present emulsion cosmetic is a cosmetic composition.
In this specification, (A) to (F) are symbolic symbols of the components, and hereinafter may be referred to as component (A), etc.

Component (A)
Component (A) is one or more substances selected from the group consisting of hydrogenated polyisobutenes with an average molecular weight of 200 or less and linear saturated hydrocarbons with 6 to 13 carbon atoms. These are volatile oils (particularly hydrocarbons). The incorporation of a volatile oil can impart a smooth, less sticky feel to the emulsion cosmetic. Furthermore, the incorporation of component (A) can improve the emulsion stability and dispersibility (aggregation inhibition) of metal oxides in the emulsion cosmetic.

Component (A), hydrogenated polyisobutene, is known as a compound obtained by polymerizing isobutene and then hydrogenating it. The hydrogenated polyisobutene contained in this emulsion cosmetic has an average molecular weight of 200 or less. Such hydrogenated polyisobutene is volatile, imparting a good feel to the cosmetic and contributing to improved emulsion stability and metal oxide dispersibility in the cosmetic. Preferably, hydrogenated polyisobutene has an average molecular weight of 100 or more. In other words, the average molecular weight of hydrogenated polyisobutene is more preferably 100 to 200. Here, the average molecular weight of hydrogenated polyisobutene refers to the number average molecular weight. The number average molecular weight (polystyrene equivalent) can be measured using GPC (gel permeation chromatography).

Specifically, the linear saturated hydrocarbon having 6 to 13 carbon atoms refers to hexane, heptane, octane, nonane, decane, undecane, dodecane, and tridecane. The linear saturated hydrocarbon having 6 to 13 carbon atoms of component (A) may be one substance selected from hexane, heptane, octane, nonane, decane, undecane, dodecane, and tridecane, or may be two or more (e.g., two, three, four, or five) substances. Preferably, the linear saturated hydrocarbon having 6 to 13 carbon atoms of component (A) is one or both of undecane and tridecane. In this case, the smooth feel of use of the present emulsion cosmetic can be effectively improved. When undecane and tridecane are contained (hereinafter, a mixture of undecane and tridecane will be referred to as "undecane-tridecane"), the mixing ratio thereof may be, for example, 1:1 to 9:1 by mass, but is not limited thereto.
Thus, in one embodiment, component (A) is preferably one or more substances selected from the group consisting of hydrogenated polyisobutene, undecane, and tridecane, each having an average molecular weight of not more than 200. This improves emulsion stability and the dispersibility (aggregation inhibition) of the metal oxide, and also makes it easier to impart a smooth, less sticky feel to the present emulsion cosmetic.

The content of component (A) in the present emulsion cosmetic (the total amount if multiple components are present) is not limited to the above, but from the perspective of obtaining a good feel when used and emulsion stability, it can be 0.5 to 30% by mass, and preferably 1 to 25% by mass, relative to the total amount of the present emulsion cosmetic (100% by mass). Furthermore, the content of component (A) is preferably 1 to 20% by mass, more preferably 2 to 15% by mass, and even more preferably 4 to 10% by mass, relative to the total amount of the present emulsion cosmetic. In this case, it is possible to impart a non-sticky, smooth feel when used, resulting in a cosmetic that is pleasant to use.

Ingredient (B)
Component (B) is a volatile silicone oil. By including component (B), the deterioration in usability that can result from the incorporation of UV absorbers or metal oxides can be suppressed, thereby imparting a smoother feel to the present emulsion cosmetic. Examples of volatile silicone oils include, but are not limited to, dimethylpolysiloxane, methyltrimethicone, and decamethylcyclopentasiloxane. These may be used alone or in combination of two or more substances. As used herein, "volatile" refers to the property of volatilizing at temperatures typically encountered when using cosmetics (e.g., 10 to 30°C), meaning the property of volatilizing at room temperature (specifically, 25°C). Specifically, this refers to silicone oils with a boiling point of 250°C or less at 1 atmosphere. The boiling point of volatile silicone oils is preferably 150°C or higher. Polymerized compounds among the components listed above can become volatile by adjusting the degree of polymerization, for example. For example, dimethylpolysiloxane is preferred because it has volatility when its viscosity (particularly kinematic viscosity) at 25°C is 1 to 2 mm ² /sec. The viscosity in this case conforms to the viscosity measurement method stipulated in Method 1 of the "Standards for Quasi-drug Ingredients 2006 (Quasi-drug Standards)." However, the value is measured at 25°C using a modified Ostwald-type capillary viscometer.

The content of component (B) in the present emulsion cosmetic is not limited to this, but from the perspective of achieving a good feel when used, it can be 0.5 to 30% by mass, preferably 1 to 25% by mass, and more preferably 3 to 15% by mass, relative to the total amount of the present emulsion cosmetic (100% by mass).

The total content of components (A) and (B) in the present emulsion cosmetic is preferably 2 to 30% by mass, based on the total amount of the present emulsion cosmetic (100% by mass). Components (A) and (B) are volatile oils, and having the total content of these components within this range contributes to a smoother feel when used. The total content of components (A) and (B) is preferably 3 to 25% by mass, and more preferably 5 to 20% by mass. The mass ratio of components (A) to (B) is preferably 1:30 to 25:1, and more preferably 1:25 to 20:1.

Ingredient (C)
Component (C) is a silicone surfactant, and the inclusion of component (C) improves the emulsion stability of the present emulsified cosmetic. In particular, when a silicone oil is blended as in component (B), the inclusion of a silicone surfactant significantly improves emulsion stability. The silicone surfactant is a copolymer having at least an organopolysiloxane group and a hydrophilic group. Examples of silicone surfactants include, but are not limited to, polyether-modified silicones having polyether chains as hydrophilic groups and polyglycerin-modified silicones having polyglycerin chains as hydrophilic groups. The silicone surfactant may be a graft copolymer having an organopolysiloxane group as the main chain and hydrophilic groups on the side chains, or a linear block copolymer or crosslinked polymer in which organopolysiloxane groups and hydrophilic groups are alternately bonded.

Examples of the polyoxyalkylene/alkyl co-modified organopolysiloxane (C4) above include, but are not limited to, cetyl PEG/PPG-10/1 dimethicone.

Component (C) is preferably one or more substances selected from the group consisting of lauryl PEG-9 polydimethylsiloxyethyl dimethicone, PEG-9 polydimethylsiloxyethyl dimethicone, PEG-10 dimethicone, and cetyl PEG/PPG-10/1 dimethicone. In this case, the emulsion stability of the present emulsion cosmetic is further improved.

The content of component (C) (or the total amount if multiple components are present) is not limited to this, but from the perspective of improving emulsion stability, it can be 0.1 to 5% by mass, preferably 0.2 to 4.5% by mass, and more preferably 0.4 to 4% by mass, relative to the total amount of the emulsion cosmetic (100% by mass).

Ingredient (D)
Component (D) is one or more substances selected from the group consisting of glycerin fatty acid esters, sorbitan fatty acid esters, and phospholipids. Component (D) may be one substance selected from the group consisting of glycerin fatty acid esters, sorbitan fatty acid esters, and phospholipids, or a combination of glycerin fatty acid esters and sorbitan fatty acid esters, a combination of sorbitan fatty acid esters and phospholipids, or a combination of glycerin fatty acid esters and phospholipids. It may also contain all of glycerin fatty acid esters, sorbitan fatty acid esters, and phospholipids. The inclusion of one or more substances selected from glycerin fatty acid esters, sorbitan fatty acid esters, and phospholipids can improve emulsion stability and dispersibility (aggregation inhibition) of metal oxides. Furthermore, when component (D) is blended with component (F) and a powder, it improves the dispersibility of component (F) and the powder, allowing the powders to adhere uniformly to the skin, thereby enhancing the skin adhesion of the emulsion cosmetic.

Egg yolk-derived phospholipids, soybean-derived phospholipids, and the like can be used as phospholipids. Phospholipids are not limited to these, but examples include lecithin, hydrogenated lecithin, and hydrogenated soybean phospholipids. Phospholipids may contain phosphatidylcholine.

It is preferable that at least one of the components (D) is a sorbitan fatty acid ester. In this case, emulsion stability can be effectively improved.

The content of component (D) (or the total amount if multiple components are present) is not limited to this, but from the perspective of improving emulsion stability, it can be 0.1 to 4.5% by mass, preferably 0.2 to 2% by mass, and more preferably 0.4 to 2% by mass, relative to the total amount of the emulsion cosmetic (100% by mass).

Here, the mass ratio ((C)/(D)) of the contents of component (C) and component (D) is preferably 0.2 to 20. By including the specific amount of component (D) in combination with component (C), it is possible to suppress the decrease in emulsion stability caused by the incorporation of an ultraviolet absorber and the decrease in dispersibility when a metal oxide is incorporated, thereby obtaining an emulsion cosmetic with excellent stability (emulsion stability and aggregation inhibition). From the perspective of enhancing this effect, this mass ratio ((C)/(D)) is more preferably 0.5 to 15.

Component (E)
The present emulsion cosmetic contains an ultraviolet absorber as component (E). In the present invention, by blending component (E) in combination with the above-mentioned components (A) to (D), it is possible to obtain an emulsion cosmetic that is less susceptible to a decrease in stability due to the blending of component (E), has excellent usability, such as smoothness, and has a high ultraviolet protection effect. Therefore, the present emulsion cosmetic is suitable for cosmetics that protect the skin from ultraviolet (UV) rays (e.g., sunscreens, etc.). A solid ultraviolet absorber is preferred as the ultraviolet absorber. A solid ultraviolet absorber can achieve a high ultraviolet absorption effect. Here, "solid" means that the ultraviolet absorber is solid at normal temperatures (e.g., 10 to 30°C) when the cosmetic is used, and is solid under conditions such as room temperature (specifically, 25°C). In the formulation of the present emulsion cosmetic, the ultraviolet absorber may be present in a state dissolved in an oily component, in a state dissolved in an aqueous component, or may remain solid, such as in particulate form. Examples of the ultraviolet absorber include organic ultraviolet absorbers, but are not limited to these. Examples include ethylhexyl methoxycinnamate, bisethylhexyloxyphenol methoxyphenyl triazine, diethylaminohydroxybenzoyl hexyl benzoate, polysilicone-15, methylenebisbenzotriazolyltetramethylbutylphenol, octocrylene, dimethicone diethylbenzalmalonate, t-butylmethoxydibenzoylmethane, ethylhexyl triazone, oxybenzone-3, phenylbenzimidazole sulfonic acid, homosalate, and ethylhexyl salicylate.

Component (E) is preferably one or more selected from the group consisting of ethylhexyl methoxycinnamate, bisethylhexyloxyphenol methoxyphenyl triazine, diethylaminohydroxybenzoyl hexyl benzoate, and polysilicone-15. In this case, it is possible to obtain an excellent UV absorption effect and a more stable formulation.

The content of component (E) (or the total amount if multiple components are present) is not limited to this, but from the perspective of obtaining UV absorption effects, it can be 1 to 20% by mass, preferably 2 to 10% by mass, and more preferably 5 to 10% by mass, relative to the total amount of the emulsion cosmetic (100% by mass).

Component (F)
Component (F) is a metal oxide. The metal oxide may be in powder form, but is typically blended in the present emulsion cosmetic in the form of metal oxide particles. The metal oxide may function as an ultraviolet light scattering agent. In this case, the ultraviolet light scattering effect can be exerted, thereby further providing the effect of protecting the skin from ultraviolet light. The metal oxide may also be a pigment. For example, the metal oxide can be used as a pigment that imparts a color such as white. Alternatively, it can be used, for example, as an extender pigment. In the present emulsion cosmetic, the metal oxide is preferably present in a dispersed state, and blending the above components (A) to (D) in combination can increase the dispersibility of the metal oxide and suppress aggregation.

Examples of metal oxides include, but are not limited to, titanium oxide, zinc oxide, cerium oxide, zirconium oxide, iron oxide, aluminum oxide, magnesium oxide, chromium oxide, and red iron oxide. The metal oxide may be surface-treated with a surface treatment agent, such as a silicone compound, an organic compound, an inorganic salt, or a fluorine compound. When a surface-treated metal oxide is used, the total mass, including the surface treatment agent, is considered to be the mass of the metal oxide in component (F). Preferably, the metal oxide in component (F) is one or two selected from the group consisting of titanium oxide and zinc oxide. These metal oxides can enhance UV scattering and/or pigment properties. Furthermore, these metal oxides can produce cosmetics with good dispersibility. When a particulate metal oxide is used, the average particle size of the metal oxide is not limited, but is preferably in the range of 10 to 10,000 nm.

Metal oxides may also be included as coating components for particles such as inorganic particles, and in the present emulsion cosmetic, such metal oxides are also included in component (F). Examples of such metal oxide-coated particles include metal oxide-coated mica and metal oxide-coated borosilicate (Ca/Al), and specific examples include iron oxide-coated mica, titanium oxide-coated mica, and titanium oxide/tin oxide-coated borosilicate (Ca/Al).

The content of component (F) (or the total amount if multiple components are present) is not limited to the above, but from the perspective of exhibiting the functions of the metal oxide (e.g., UV scattering properties, pigment properties), it can be 1 to 30% by mass, preferably 3 to 25% by mass, and more preferably 5 to 20% by mass, relative to the total amount of the emulsion cosmetic (100% by mass). In one embodiment, the content of component (F) is preferably 5% by mass or more relative to the total amount of the emulsion cosmetic. In this case, the functions of the metal oxide (e.g., UV scattering properties, pigment properties) can be more effectively exhibited. In particular, the content of the metal oxide is preferably 5 to 20% by mass. In the present invention, by combining component (F) with the above components (A) to (D), it is possible to obtain an emulsion cosmetic that has good emulsion stability, inhibits aggregation, and is excellent in usability, such as smoothness, even when the amount of component (F) is relatively high (e.g., 5% by mass or more).

Other components: Water The present emulsion cosmetic may contain water as another component other than those mentioned above. In a water-in-oil emulsion cosmetic, the emulsion form is water-in-oil (W/O), with the oil phase being the external phase and the aqueous phase being the internal phase. The aqueous phase may contain water-soluble substances and hydrophilic substances. The water is not limited to these, but purified water is preferably used.

The water content in this water-in-oil emulsion cosmetic is not limited to, but can be 1 to 90% by mass, preferably 10 to 80% by mass, more preferably 20 to 70% by mass, and even more preferably 30 to 60% by mass. Furthermore, depending on the formulation, the water content may be 50% by mass or less.

The present emulsion cosmetic may contain various components that can be blended as water-in-oil emulsion cosmetics.

The present emulsion cosmetic may be a skin cosmetic or a hair cosmetic. It is particularly preferable that the present emulsion cosmetic is a skin cosmetic (a water-in-oil emulsion cosmetic for the skin). Furthermore, the present emulsion cosmetic can be used for a wide range of applications, including skin care products and makeup products. The present emulsion cosmetic can provide a smooth feel during use (application), is not sticky after application, and has excellent adhesion to the skin.

Skin cosmetics are not particularly limited as long as they are in the form of a water-in-oil emulsion, and can be used as cosmetics for a variety of purposes. Examples include emulsions, creams, serums, sunscreens, hand creams, eye creams, body creams, makeup cosmetics, concealers, blushers, makeup bases, and foundations (e.g., liquid foundations and solid foundations). Methods of using skin cosmetics include applying them to hands or fingers, using cotton, impregnating nonwoven fabric, and spraying or misting them.

Hair cosmetics are not particularly limited as long as they are in the form of a water-in-oil emulsion, and can be used as cosmetics for a variety of purposes. Examples include cosmetics such as hair cream, hair wax, hair rinse, hair mask, hair treatment, and sunscreen for hair. Methods of using hair cosmetics include applying them to the hands or fingers, or spraying them on as a mist or spray.

The present emulsion cosmetic can be produced by mixing the above-mentioned components. For example, a method can be used in which a preheated and mixed aqueous component and a preheated and mixed oily component are mixed and emulsified, and then cooled. Of course, the method for producing the present emulsion cosmetic is not limited to this.

This specification discloses a method for producing a water-in-oil emulsion cosmetic, which includes mixing components (A) to (F). As described above, by blending components (E) and (F) in combination with components (A) to (D), the emulsion is stabilized, allowing for the production of a stable cosmetic in which components (E) and (F) are well dissolved or dispersed. An appropriate emulsifier or kneader (e.g., a triple-roller mixer, homomixer, etc.) can be used in the production.

The water-in-oil emulsion cosmetic of the present invention will be explained below using examples, but the present invention is not limited to these examples.

Usability (smooth application, non-sticky finish, adhesion to skin)
A usability test was conducted by a panel of 20 experts on each sample (the cosmetics of Examples 1 to 24 and Comparative Examples 1 to 8). The cosmetics were applied to the forearm, and the feel upon application was evaluated by sensory evaluation in three categories (smooth feel upon application, non-stickiness upon application, and adhesion to the skin) based on the results of a questionnaire, using the following criteria:
◎: 15 or more out of 20 people answered that it was good. 〇: 10 to 14 out of 20 people answered that it was good. △: 5 to 9 out of 20 people answered that it was good. ×: 4 or less out of 20 people answered that it was good.

Formulation stability (pigment dispersibility, emulsion stability)
Each sample (the cosmetic compositions of Examples 1 to 24 and Comparative Examples 1 to 8) was filled into a glass bottle, sealed, and stored in a thermostatic chamber at 40°C for one month. The stored products were visually observed for any changes in appearance, with the state immediately after production being used as the standard, and judged according to the following criteria. Note that metal oxides in the above examples mainly refer to pigments.
Pigment dispersibility (whether or not pigment aggregation occurs)
◎: No aggregation ○: Slight aggregation, but disappears when mixed △: Slight aggregation, but does not disappear when mixed ×: Significant aggregation Emulsion stability (presence or absence of separation of the internal aqueous phase)
◎: No separation ○: Slight separation, but disappears when mixed △: Slight separation, but does not disappear when mixed ×: Significant separation

Results Examples 1 to 24, which contain components (A) to (F), were rated ◯ or ⊚ in all evaluation items (smooth feel in use, non-stickiness after application, adhesion to skin, pigment dispersibility, and emulsion stability), demonstrating good formulation stability and feel in use. On the other hand, Comparative Examples 1 to 3, 5, and 6 had poor formulation stability, Comparative Example 4 was sticky after application, and Comparative Examples 6 to 8 had poor adhesion to skin.
