Description

[Technical field]

[0001] The present invention relates to a water-in-oil emulsion composition containing a powder. [Background technology]

[0002] Cosmetics are known as compositions containing powder. When a cosmetic containing powder is applied to the skin, the powder adheres to the skin, forming a cosmetic film, and the cosmetic effect of the powder can be expressed. Therefore, in cosmetics containing powder, it is very important that the powder adheres to the skin (excellent adhesion). In order to improve adhesion to the skin, various technologies have been developed so far. For example, Patent Document 1 discloses that the adhesion to the skin is improved by performing a surface treatment with silicone gel on the powder to be blended. In addition, Patent Document 2 discloses that the adhesion to the skin is improved by performing a surface treatment with mannosylerythritol lipid on the powder.

[0003] On the other hand, a composition containing a powder has a problem that the powder aggregates in various powder dispersion systems (including emulsion systems) such as in water-based liquids, oil-based liquids, and powder systems, and it is not easy to make the powder uniformly dispersed. In particular, talc, titanium oxide, and zinc oxide are widely used ingredients because they enhance the adhesion effect to the skin, but as the adhesion to the skin improves, the powder's aggregation property may become a problem. If the powder remains aggregated, problems such as a deterioration in the feeling of use (a squeaky feeling due to the powder), a phenomenon in which the appearance color of the cosmetic differs from the applied color, and a phenomenon in which color unevenness occurs in the cosmetic film are caused. Therefore, various dispersion techniques have been developed as a method for stably dispersing the powder, such as the investigation of surface treatment agents, the blending of surfactants or water-soluble polymers, and the addition of clay minerals. For example, Patent Document 3 proposes an oil-in-water emulsion cosmetic in which a specific polymer is combined with a hydrophilically treated powder. In addition, Patent Document 4 proposes an oil-in-water emulsion cosmetic in which a specific polymer is combined with a hydrophobic powder. Moreover, Patent Document 5 proposes a cosmetic preparation using a dispersion technique that combines a fluorine-treated powder and a silicone surfactant.

[0004] However, it is not easy to improve the dispersibility of the powder while ensuring adhesion to the skin and improving the feeling of use. This is because the powder may be more likely to aggregate if the powder adhesion to the skin is improved. Therefore, it is very difficult to develop a composition containing a powder that has both good dispersibility and good adhesion, but it is desirable. [Prior art documents] [Patent documents]

[0008] According to the present invention, it is possible to provide a water-in-oil emulsion composition in which the dispersibility of the powder is good and the adhesion of the powder to the skin is good. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The water-in-oil emulsion composition of the present invention comprises the following components (A) to (E): (A) Mannosylerythritol lipid; (B) Water-containing oil; (C) Powder; (D) silicone surfactants; and (E) purified water, (hereinafter, also referred to as the present emulsion composition or the present composition). The present emulsion composition contains a powder, and can also be called a powder-containing water-in-oil emulsion composition, a powder-containing emulsion composition, or a powder-containing composition.

[0010] Component (A) Component (A) is mannosylerythritol lipid. Mannosylerythritol lipid is a compound having fatty acid and acetyl group as hydrophobic group and sugar alcohol erythritol and mannose as hydrophilic group, and is a kind of biosurfactant. Biosurfactant is a surfactant that can be produced from vegetable oils and fats by microorganisms, and can have beneficial functions such as low toxicity, high biodegradability, and wide range of biological activity in addition to emulsifying ability, dispersing ability, solubilizing ability, etc. Mannosylerythritol lipid is a compound that can be produced by treating vegetable oil such as olive oil and soybean oil with yeast. Examples of yeast include yeast of the genus Pseudozyma (e.g., Pseudozyma antarctica), but are not limited thereto. Mannosylerythritol lipids with different structures and characteristics can be produced depending on the vegetable oil as raw material, the yeast used, the production method, etc., but in the present invention, there is no particular limitation, and any mannosylerythritol lipid that can be used as a cosmetic raw material can be used. Details of the structure, characteristics, production method, etc. of mannosylerythritol lipid are described in, for example, "Research on the expansion of the structure and function of yeast-derived functional glycolipids (biosurfactants)" by Fukuoka Tokuma in Cosmetology Research Report, vol. 19, 2011, pp. 58-62, and "Production and development of applications of biosurfactants by the genus Pseudozyma" by Morita Tomotake in the Journal of Biotechnology, Vol. 94, No. 5, pp. 252-254.

[0011] Mannosylerythritol lipid has a hydrophobic group of fatty acid and acetyl group, and a hydrophilic group of sugar alcohol, so it is believed that it interacts with powder and easily binds to the powder surface, and modifies the surface of the powder, thereby improving the adhesion of the powder to the skin. In particular, mannosylerythritol lipid contains many hydroxyl groups (OH), which strengthens the binding action with powder and can further improve the adhesion of powder to the skin. Furthermore, mannosylerythritol lipid has excellent affinity (compatibility) with the living body, and when it is blended into a water-in-oil emulsion composition containing powder, it is easy to obtain effects such as the powder easily adheres to the skin (easy to form a cosmetic film), long-lasting makeup, and smooth feel (spreadability).

[0012] The content of component (A) in the present composition is not limited to this, but from the viewpoints of powder dispersibility and adhesion to the skin, it is, for example, preferably 0.0001 to 10 mass%, more preferably 0.0005 to 5 mass%, and even more preferably 0.001 to 3 mass%, relative to the total amount of the present composition (100 mass%).

[0013] Ingredient (B) Component (B) is a water-holding oil. In this specification, the water-holding oil means an oil that can hold water equal to or more than its own weight, that is, an oil having a water-holding capacity of 100% or more. The water-holding oil can exhibit water-holding capacity due to the presence of a hydrophilic portion in the molecule. By using a water-holding oil, the hydrophilic portion of the water-holding oil interacts with the hydrophilic group of component (A), thereby increasing the dispersibility of component (A), allowing component (A) to be uniformly dispersed in the system, and the dispersibility and adhesiveness of the powder due to component (A) can be further improved. In addition, the binding force of component (A) to the powder can be improved, and the dispersibility and adhesiveness of the powder due to component (A) can be further improved. Here, as described above, generally, when a specific component is added to a powder to increase the adhesiveness of the powder to the skin, the cohesiveness of the powder itself may also increase, and in that case, it may be difficult to obtain a uniform dispersion. However, by combining component (A) and component (B), it is possible to improve the adhesion to the skin while suppressing the aggregation of the powder in the preparation, and it is possible to improve both the adhesion of the powder and the adhesion to the skin. Furthermore, the combination of component (A) and component (B) can increase the affinity to the skin and also improve the cosmetic durability and usability.

[0014] The water holding capacity of a water-holding oil agent can be confirmed by the following water holding capacity test. That is, at room temperature (e.g. 20°C), purified water is added dropwise little by little to 10 g of oil agent while stirring and kneading with a stirring rod or the like, and the end point is reached when the water can no longer be kneaded in. The weight of the mixture (water-containing oil agent) at the end point is measured and the water holding capacity is calculated using the following formula. An oil agent with a water holding capacity of 100% or more calculated by this formula is considered to be a water-holding oil agent. Water holding capacity (%) = [weight of added water (g)] / [weight of oil at the start (10g)] x 100

[0015] The water-holding oil agent of component (B) is preferably one or more water-holding oil agents selected from the group consisting of polyhydric alcohol hydroxy fatty acid esters and phytosterol derivatives. In this case, the dispersibility of component (A) can be improved, and the binding force of component (A) to the powder can be efficiently improved, thereby further improving the dispersibility and adhesion of the powder. Examples of the polyhydric alcohol hydroxy fatty acid ester include dipentaerythrityl hexa(hydroxystearic acid / stearic acid / rosin acid) and dipentaerythrityl tripolyhydroxystearate. Examples of phytosterol derivatives include dimer dilinoleic acid (phytosteryl / isostearyl / cetyl / stearyl / behenyl), dimer dilinoleic acid di(isostearyl / phytosteryl), dilauroyl glutamic acid di(phytosteryl / octyldodecyl), dilauroyl glutamic acid di(octyldodecyl / phytosteryl / behenyl), macadamiate phytosteryl, isostearate phytosteryl, and hydroxystearate phytosteryl. Examples of water-holding oil agents other than those mentioned above include liquid lanolin and (isostearic acid / behenic acid)(glyceryl / polyglyceryl-6) esters. From the viewpoint of powder dispersibility and adhesion, polyhydric alcohol hydroxy fatty acid esters are more preferable as component (B). It is particularly preferable that component (B) is hexa(hydroxystearic acid / stearic acid / rosin acid) dipentaerythrityl. In that case, the dispersibility and adhesion of the powder can be further improved. As the component (B), one of the above-mentioned compounds may be used alone, or two or more of them may be used in combination.

[0016] The content of component (B) in the present composition (the total amount when multiple components are present) is not limited to this, but from the viewpoints of powder dispersibility and adhesion to the skin, it is, for example, preferably 0.001 to 20 mass%, more preferably 0.005 to 15 mass%, and even more preferably 0.01 to 10 mass%, relative to the total amount of the present composition (100 mass%).

[0017] Here, the ratio of component (A) to component (B) ((A) / (B)) is preferably 0.0001 to 5 by mass. When the ratio of the content of component (A) to the content of component (B) is within this range, the dispersibility of component (A) can be increased by component (B), and the binding property of component (A) to the powder can be efficiently improved, and the dispersibility and adhesiveness of the powder can be further improved. From the viewpoint of further obtaining the above effects and from the viewpoint of the feeling of use, this ratio ((A) / (B)) is more preferably 0.0005 to 3, and even more preferably 0.001 to 1. This ratio ((A) / (B)) may further be 0.01 to 0.8.

[0018] Ingredients (C) Component (C) is a powder. By blending the powder, effects such as ultraviolet scattering effect, makeup effect, and improved usability can be imparted. The powder of component (C) can be appropriately selected from powders that can be used as cosmetic raw materials. Here, the powder is a component that is blended into the composition as a powder. That is, the powder of component (C) is a component that exists as a powder (solid) in the composition and exhibits the function of a powder, and those that dissolve in a solvent or do not maintain a powder state are not included in the powder of component (C). And, it is preferable that the powder maintains the powder state even under heating conditions during the production of the composition. For example, substances that dissolve in water or a solvent and substances that melt when heated to 70°C or higher are not suitable as powders.

[0019] The powder is not particularly limited by its shape such as spherical, plate-like, spindle-like, needle-like, etc., particle size such as mist-like, fine particles, pigment-grade, etc., particle structure such as porous, non-porous, etc. The powder of component (C) can be appropriately used from fine particles to relatively large particles, and is not limited thereto, but for example, particles having an average particle size of 10 nm or more and 50 μm or less can be used. In this specification, the average particle size of the powder is the volume average particle size measured using a laser diffraction type particle size distribution meter. Examples of the powder include inorganic powders, glittering powders, organic powders, colored pigments, composite powders, etc.

[0022] 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-acyllysine, nylon, polymethylsilsesquioxane, crosslinked organopolysiloxane polymers, polystyrene, polyurethane, polyethylene, polypropylene, polyethylene terephthalate, polymethacrylic acid esters such as polymethyl methacrylate, and crosslinked polymethacrylic acid esters such as methyl methacrylate crosspolymers; complexes of polymethyl methacrylate and polyisoprene, polyacrylic acid esters, acrylonitrile-methacrylic acid copolymer powders, polytetrafluoroethylene, and (HDI / PPG / polycaprolactone) crosspolymers.

[0024] Component (C) is preferably 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, and a water-in-oil emulsion composition having good powder adhesion can be obtained. In addition, talc, titanium oxide, and zinc oxide are powders having coagulation properties, but the combination of component (A) and component (B) effectively suppresses coagulation. In addition, these powders can enhance the functions of the emulsion composition containing the powder, such as ultraviolet scattering effect, makeup effect, and improved usability. Hereinafter, talc, titanium oxide, and zinc oxide are also referred to as component (C1).

[0025] The talc that can be used is not particularly limited in terms of shape (e.g., spherical, plate-like, needle-like, irregular, etc.) or particle structure (e.g., porous, non-porous, etc.) so long as it is a talc that is commonly used in cosmetics. For example, talc having an average particle diameter of 2 to 30 μm can be used.

[0026] Titanium oxide may be used without any particular limitations on its shape, such as spherical, plate-like, needle-like, or irregular shape, or on its particle structure, such as porous or nonporous, as long as it is titanium oxide that is normally used in cosmetics. Titanium oxide may be of the rutile type or anatase type. Titanium oxide having an average particle diameter of, for example, 10 to 1,000 nm may be used.

[0027] The zinc oxide that can be used is not particularly limited as long as it is zinc oxide that is normally used in cosmetics, and may be of any shape such as spherical, plate-like, needle-like, or irregular shape, or of a particle structure such as porous or nonporous. For example, zinc oxide having an average particle diameter of 10 to 5,000 nm can be used.

[0028] The powder of component (C) (particularly inorganic powder such as talc, titanium oxide, and zinc oxide) may be a powder whose surface has been treated with a surface treatment agent (surface-treated powder). The surface treatment can further suppress the aggregation of the powder. The surface treatment can also increase the adhesion of the powder. Furthermore, the surface treatment can also increase the functionality (usage sensation, etc.) of the powder. Examples of the surface treatment 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.

[0029] Also, as the powder, a powder treated with the above-mentioned component (A) (i.e., mannosylerythritol lipid) can be used. In that case, the dispersibility and adhesion of the powder can be further improved. Component (C) (powder) treated with component (A) is represented as component (CA). Also, component (C1) (talc, titanium oxide and zinc oxide) treated with component (A) is represented as component (C1A). Examples of powders treated with component (A) include titanium oxide treated with mannosylerythritol lipid, zinc oxide treated with mannosylerythritol lipid, talc treated with mannosylerythritol lipid, mica treated with mannosylerythritol lipid, and titanium mica treated with mannosylerythritol lipid. When a powder treated with component (A) is used, component (A) may be further blended in addition to the powder (i.e., component (CA)), or component (A) in the powder alone may function as component (A) of the present composition without blending component (A) separately.

[0030] The amount of the surface treatment agent is preferably 0.1 to 30 mass% of the untreated powder, more preferably 0.5 to 20 mass%, and even more preferably 1 to 10 mass%. The amount (%) of the surface treatment is the amount when the entire powder including the surface treatment agent is taken as 100% (i.e., the amount of the treatment agent).

[0031] The surface treatment can be carried out by a conventional method. For example, a surface treatment agent and powder particles to be treated are added to a solvent, and the mixture is stirred in a ball mill or the like, dried as necessary, washed with water, and filtered repeatedly to remove impurities, and then dried and pulverized to obtain the desired surface-treated powder. In addition, several types of compounds can be surface-treated simultaneously with a surface treatment agent, or one of the compounds can be surface-treated in advance, and then another compound can be surface-treated.

[0032] The powder of component (C) may be used alone or in combination of two or more. When two or more types of powders are blended, a water-in-oil emulsion composition having the characteristics of each powder can be obtained. For example, the UV protection effect, makeup effect, and usability can be improved. Furthermore, talc, titanium oxide, and zinc oxide, which are component (C1), may be used in multiple amounts.

[0033] In the present composition, the content of component (C) (the total amount when there are multiple components) is preferably 0.1 to 60 mass% with respect to the total amount of the present composition (100 mass%). When the content of component (C) is 0.1 mass% or more, the above-mentioned effect of the powder can be further enhanced. When the content of component (C) is 60 mass% or less, a composition in which the powder is stably blended can be easily obtained. The content of component (C) is more preferably 0.5 to 50 mass%, and even more preferably 1 to 40 mass%. Here, in the case of surface-treated powder, each content is the amount including the surface-treated component, and similarly, in the case of coated powder, each content is the amount including the coating component. However, in the case of powder treated with component (A) (i.e., components (CA) and (C1A)), the amount of the component (C) is calculated as the amount of the treated component (A) from the total amount of the powder, and the treated component (A) is calculated as the amount of the component (A). That is, the treated component (A) used in the powder treatment is not included in the content of component (C), but is included in the content of component (A). In this way, the total amount of component (A) in the composition is calculated. Therefore, in the ratio of components (A) and (B) described above, when component (C) 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 this ratio ((A) / (B)) is calculated. In addition, when component (C1) treated with component (A) is used, the content of component (C1) is calculated excluding component (A).

[0034] Here, the ratio of component (C) to the total of components (A) and (B) ((C) / ((A)+(B))) is preferably 0.1 to 5,000 by mass. When the ratio of the content of component (C) to the total content of components (A) and (B) is within this range, the improvement in the dispersibility and adhesion of the powder by components (A) and (B) can be obtained more efficiently, and a composition having a good usability can be obtained. From the viewpoint of obtaining the above-mentioned effects more effectively and from the viewpoint of the usability, the ratio ((C) / ((A)+(B))) is more preferably 0.5 to 2,000, and even more preferably 1 to 1,000. As described above, when component (C) that has been treated with component (A) is used, the amount of treated component (A) in the raw material (ingredients) is added to the amount of component (A), and the amount of component (C) is the amount remaining after subtracting treated component (A) from the total amount of powder, and the ratio ((C) / ((A)+(B))) is calculated.

[0035] The content of component (C1), i.e., talc, titanium oxide, and zinc oxide (the total amount when more than one is present) is preferably 0.1 to 60 mass% based on the total amount of the composition (100 mass%). By having the content of component (C1) within this range, it is possible to obtain a composition that has good dispersibility, excellent adhesion, and a good feel when used. The content of component (C1) is more preferably 1 to 50 mass%.

[0036] Here, the ratio ((C1) / ((A)+(B))) of component (C1) to the total of components (A) and (B) is also preferably 0.1 to 5,000 by mass ratio. When the ratio of the content of component (C1) to the total content of components (A) and (B) is within this range, the improvement in the dispersibility and adhesion of the powder by components (A) and (B) can be obtained more efficiently, and a composition with good usability can be obtained. From the viewpoint of obtaining the above-mentioned effects and from the viewpoint of usability, this ratio ((C1) / ((A)+(B))) is more preferably 0.5 to 2,000, and even more preferably 1 to 1,000. The calculation when component (C1) treated with component (A) is used is the same as above.

[0037] Ingredients (D) Component (D) is a silicone surfactant. In this composition, by using a silicone surfactant as a surfactant for emulsification, the dispersibility and adhesion of the powder can be further improved, and the formulation stability can also be improved. Although not limited to the following theory, it is speculated that the silicone surfactant can help disperse component (A) in the system in the same way as component (B) by the hydrophilic site (hydrophilic group) of the silicone surfactant, and can further improve the dispersibility and adhesion of the powder. In addition, the hydrophilic site (hydrophilic group) of the silicone surfactant is likely to interact with the hydrophilic site of the water-holding oil agent of component (B), and does not hinder the dispersibility of component (A) by component (B) and the improvement of the dispersibility and adhesion of the powder by component (A), but can actually improve them. In addition, the silicone surfactant is compatible with oil agents including component (B), so that the stability of the formulation can be improved. The silicone surfactant preferably has a PEG or polyglyceryl site as the hydrophilic site, and a silicone and / or alkyl site as the hydrophobic site.

[0038] Component (D) is more preferably an alkyl-modified silicone surfactant. In that case, as described above, like component (B), it can help component (A) disperse in the system, further improving the dispersibility and adhesion of powder, and the alkyl moiety enhances the interaction with component (B), further improving the dispersibility of component (A) by component (B), and the dispersibility of powder and formulation stability. In this specification, the alkyl-modified silicone surfactant is referred to as component (D1).

[0039] Examples of alkyl-modified silicone surfactants include, but are not limited to, lauryl PEG-9 polydimethylsiloxyethyl dimethicone, lauryl polyglyceryl-3 polydimethylsiloxyethyl dimethicone, cetyl PEG / PPG-10 / 1 dimethicone, (PEG-15 / lauryl dimethicone) crosspolymer, (dimethicone / (PEG-10 / 15)) crosspolymer, (acrylates / ethylhexyl acrylate / dimethicone methacrylate) copolymer, and the like.

[0040] Examples of silicone surfactants other than those mentioned above include PEG-9 polydimethylsiloxyethyl dimethicone, PEG-10 dimethicone, PEG-9 dimethicone, PEG-3 dimethicone, PEG-9 methyl ether dimethicone, PEG-11 methyl ether dimethicone, PEG-32 methyl ether dimethicone, PEG / PPG-20 / 22 butyl ether dimethicone, etc. Component (D) may be used alone or in combination of two or more kinds.

[0041] The content of component (D) in the present composition (the total amount when multiple components are present) is not limited to this, but from the viewpoint of improving the dispersibility of component (A) by component (B) and the dispersibility and adhesion of the powder, it is, for example, preferably 0.001 to 20 mass%, more preferably 0.01 to 10 mass%, and even more preferably 0.1 to 8 mass%, relative to the total amount (100 mass%) of the present composition.

[0042] Here, the ratio (((A)+(B)) / (D)) of the total of components (A) and (B) to component (D) is preferably 0.001 to 20 by mass ratio. When the ratio of the total content of components (A) and (B) to the content of component (D) is within this range, the improvement in the dispersibility and adhesion of the powder due to the combination of components (A), (B) and (D) can be obtained more efficiently, and a composition with a good usability can be obtained. From the viewpoint of obtaining the above-mentioned effects more effectively and from the viewpoint of the usability, the ratio (((A)+(B)) / (D)) is more preferably 0.005 to 15, and even more preferably 0.01 to 10.

[0043] The ratio (((A)+(B)) / (D1)) of the total of components (A) and (B) to component (D1) is also preferably 0.001 to 20 by mass. When the ratio of the total content of components (A) and (B) to the content of component (D1) is within this range, the improvement in the dispersibility and adhesion of the powder due to the combination of components (A), (B) and (D1) can be obtained more efficiently, and a composition with a good usability can be obtained. From the viewpoint of obtaining the above-mentioned effects and from the viewpoint of usability, the ratio (((A)+(B)) / (D1)) is more preferably 0.005 to 15, and even more preferably 0.01 to 10.

[0044] Ingredient (E) Component (E) is water. By incorporating water, the aqueous phase of the emulsion composition can be formed. This composition is a water-in-oil (W / O) emulsion composition, and water exists as an internal phase. The presence of water makes it easy to incorporate water-soluble components into the composition. The water of component (E) is preferably purified water.

[0045] The content of component (E) in the present composition is not limited to this, but from the viewpoint of increasing emulsion stability and improving the feel when used, it is, for example, preferably 1 to 70 mass%, more preferably 5 to 60 mass%, and even more preferably 10 to 50 mass%, relative to the total amount (100 mass%) of the present composition.

[0046] Component (F) The present composition preferably contains an ultraviolet absorber as component (F). By containing an ultraviolet absorber, a composition that can be used as a cosmetic for ultraviolet protection can be obtained. In addition, when the powder of component (C) has an ultraviolet scattering function, by blending the ultraviolet absorber of component (F), it is possible to simultaneously scatter and absorb ultraviolet rays, thereby obtaining a composition with higher functionality.

[0047] The ultraviolet absorber of component (F) may be a liquid ultraviolet absorber or a solid ultraviolet absorber, and may be only a liquid ultraviolet absorber, only a solid ultraviolet absorber, or both a liquid ultraviolet absorber and a solid ultraviolet absorber. The ultraviolet absorber of component (F) preferably contains a liquid ultraviolet absorber. This makes it possible to obtain a composition with excellent formulation stability. In addition, it is also preferable that the ultraviolet absorber of component (F) is two or more types including at least one of a liquid ultraviolet absorber and a solid ultraviolet absorber. By containing both a liquid ultraviolet absorber and a solid ultraviolet absorber, a higher ultraviolet absorbing ability can be obtained. Here, the liquid or solid of the ultraviolet absorber refers to the state of the ultraviolet absorber alone at room temperature (e.g., 20°C). The solid and liquid ultraviolet absorbers may be dispersed or dissolved in the composition and may not be in a solid or liquid state. In this specification, the solid ultraviolet absorber is referred to as component (F1).

[0048] Examples of liquid ultraviolet absorbents include cinnamic acid derivatives and polysilicones, and more specifically, for example, ethylhexyl paramethoxycinnamate, ethylhexyl methoxycinnamate, polysilicone-15, etc. As a liquid ultraviolet absorbent, ethylhexyl methoxycinnamate is particularly preferred, since it has high polarity and can improve solubility and stability. Examples of solid ultraviolet absorbents include diethylamino hydroxybenzoyl hexyl benzoate, bisethylhexyloxyphenol methoxyphenyl triazine, ethylhexyl triazone, methylene bisbenzotriazolyl tetramethylbutylphenol, etc.

[0049] The content of component (F) in the composition (the total amount when multiple components are present) is not limited to this, but from the viewpoint of enhancing the ultraviolet absorbing ability of the composition, it is, for example, preferably 0.1 to 20 mass%, more preferably 0.1 to 15 mass%, and even more preferably 0.5 to 10 mass%, relative to the total amount (100 mass%) of the composition.

[0050] The ratio ((F1) / (F)) of component (F1) (solid ultraviolet absorber) to component (F) (total ultraviolet absorber) is preferably 0.001 to 0.9 by mass. When the ratio of the content of component (F1) to the content of component (F) is within this range, a composition with high ultraviolet absorbing ability can be obtained. From the viewpoint of further achieving the above-mentioned effects, this ratio ((F1) / (F)) is more preferably 0.005 to 0.7, and even more preferably 0.01 to 0.5.

[0051] Ingredients (G) Component (G) is a silicone oil. The present composition preferably contains silicone oil as component (G). The present composition may contain an oil other than the water-holding oil of component (B) as a constituent of the emulsion composition, but preferably contains silicone oil (component (G)). Silicone oil has good affinity with silicone surfactants and can form an oil phase together with the water-holding oil, so that the dispersibility of powder can be further improved. Silicone oil is also suitable for the external phase of a water-in-oil (W / O) emulsion composition, and a stable emulsion composition can be obtained. Silicone oil can also impart a smooth feel to the composition by suppressing stickiness. In the present composition, silicone oil may be the main component (the component with the largest amount) of the oil.

[0052] Examples of silicone oils include, but are not limited to, decamethylcyclopentasiloxane, methyltrimethicone, dimethicone, diphenyldimethicone, phenyltrimethicone, diphenylsiloxyphenyltrimethicone, etc. Component (G) may be used alone or in combination of two or more.

[0053] The content of component (G) in the present composition (the total amount when multiple components are present) is not limited to this, but from the viewpoint of improving the dispersibility and adhesion of the powder, and from the viewpoint of improving the feel when used, it is, for example, preferably 1 to 70 mass%, more preferably 5 to 60 mass%, and even more preferably 10 to 50 mass%, relative to the total amount (100 mass%) of the present composition.

[0054] Here, the ratio ((D) / (G)) of component (D) (silicone surfactant) to component (G) (silicone oil) is preferably 0.001 to 1 by mass. When the ratio of the content of component (D) to the content of component (G) is within this range, an emulsion composition with good formulation stability can be obtained. From the viewpoint of further obtaining the above-mentioned effects, this ratio ((D) / (G)) is more preferably 0.01 to 0.8, and even more preferably 0.1 to 0.5.

[0055] Other Ingredients In addition to the above components, the present composition may contain components that are normally used in cosmetics that are water-in-oil emulsion compositions, such as surfactants other than those mentioned above, oils other than those mentioned above, monohydric alcohols or polyhydric alcohols, preservatives, antioxidants, cosmetic ingredients, antibacterial agents, chelating agents (EDTA, etc.), etc., as appropriate, within the scope that does not impair the effects of the present invention. For example, oils other than those mentioned above may include natural or synthetic ester oils (isotridecyl isononanoate, etc.), hydrocarbon oils (isododecane, etc.), higher alcohols, fatty acids, etc. The oils may be used alone or in combination of two or more. Examples of monohydric alcohols include ethanol, etc. Examples of polyhydric alcohols include 1,3-butylene glycol, dipropylene glycol, etc.

[0056] Cosmetics The present emulsion composition is preferably a cosmetic composition. In one preferred embodiment, the cosmetic composition is a liquid-based cosmetic in which powder is dispersed. Liquid-based cosmetics in which powder is dispersed include cosmetics in which powder is uniformly dispersed, cosmetics in which the container of the cosmetic is shaken when used, and the like. Alternatively, the present emulsion composition may be a solid or semi-solid (particularly paste-like) cosmetic in which powder is dispersed. In cosmetics containing powder, dispersibility in the formulation (including cases in which the powder is dispersed when used) is important, and the present composition makes it possible to obtain an emulsion cosmetic in which the powder has good dispersibility.

[0057] The emulsion composition may be a skin cosmetic or a hair cosmetic. The emulsion composition is particularly preferably a skin cosmetic (a water-in-oil emulsion composition for skin). The emulsion composition is also applicable to cosmetics containing powder for any purpose, including skin care products and makeup products.

[0058] The skin cosmetic is not particularly limited, and can be used as a cosmetic for various purposes as a water-in-oil emulsion composition (e.g., liquid cosmetic). Examples of the cosmetic include makeup cosmetics, foundations (e.g., liquid foundations, powder foundations, solid foundations, oil-based solid foundations), pressed powders, blushes, eye shadows, eye colors, concealers, face powders, lipsticks, bases (makeup bases), sunscreens, skin care cosmetics, milky lotions, creams, and other cosmetics. Methods of using the skin cosmetic include applying it to hands or fingers, using cotton, using a puff or matte, and directly applying a solid cosmetic.

[0059] The hair cosmetic is not particularly limited, and can be used as a cosmetic for various purposes as a water-in-oil emulsion composition. For example, it can be used as a hair cream, hair wax, hair rinse, hair mask, hair treatment, sunscreen for hair, etc. The method of using the hair cosmetic can be applied to hands or fingers, sprayed or misted, etc.

[0060] The water-in-oil emulsion composition can be produced by mixing the above-mentioned components. For example, the oil component (including component (B) and the like) and the aqueous component (including component (E) and the like) are separately mixed at room temperature or while being heated to a high temperature such as 70°C or higher as necessary to dissolve the solid components, and an oil phase and an aqueous phase are prepared, and then mixed at room temperature to emulsify, thereby obtaining a water-in-oil emulsion composition. The powder may be added to the oil component, the aqueous component, or the composition after emulsification. In the production, an appropriate emulsifier or kneader (for example, a three-roller, a homomixer, etc.) can be used.

[0061] In the production of the present emulsion composition, it is preferable to include a step of mixing the powders of component (A) and component (B) with component (C) to obtain a mixture. In this way, by first mixing the powders of component (A) and component (B) with component (C), the dispersibility and adhesion of the powders can be efficiently improved. And, it is preferable to mix the powder of component (C) in the presence of component (A) and component (B). The powder of component (C) may be mixed by adding the powder of component (C) to the mixture of component (A) and component (B), or by adding the mixture of component (A) and component (B) to the powder of component (C). After preparing the mixture of components (A), (B) and (C), an oil phase and an aqueous phase are separately prepared as appropriate, mixed under heating, and cooled to obtain an emulsion composition. At that time, the mixture of components (A), (B) and (C) can be added to the oil phase. Here, component (D) can be blended in the oil phase. Alternatively, component (D) may be added to a mixture of components (A), (B) and (C). Component (E) is blended in the water phase. Component (F) can be blended in the oil phase. Component (G) is blended in the oil phase. In this way, the mixture of components (A), (B) and (C) can be mixed sequentially with other components including components (D) and (E). In addition, when a powder treated with component (A) (i.e., component (CA)) is used, the powders of components (A) and (B) and (C) can be mixed by mixing components (C) and (B) treated with component (A). In addition, the above describes a preferred embodiment of mixing components such as components (A), (B) and (C), and the mixing of these components is not limited to the above description. EXAMPLES

[5] The aqueous mixture (component (E) and the like) was added to the dispersion obtained in [4] above, and emulsified to obtain a water-in-oil emulsion cosmetic.

[0070] Manufacturing methods of Comparative Examples 1 to 7 Comparative Examples 1, 4, and 5 were each produced in the same manner as in Example 1 above, except that either component (A) or component (B) was not blended. Comparative Examples 2 and 3 were produced in the same manner as in Example 1 above, except that an aqueous solution of sodium dilauroyl glutamate lysine and lecithin were used instead of component (A), respectively. Comparative Example 6 was produced in the same manner as in Example 1 above, except that shea butter was used instead of component (B). Comparative Example 7 was produced in the same manner as in Example 1 above, except that component (C) was not blended.

[0071] evaluation The preparations of the Examples and Comparative Examples shown in Tables 1 to 3 were evaluated by the following methods.

[0072] Powder dispersibility (uniform dispersion) The condition of each sample immediately after production was visually confirmed. (Judgment criteria) ◎: No aggregates or white streaks ○: Either aggregates or white streaks are slightly observed △: Both aggregates and white streaks are slightly observed ×: Multiple aggregates and / or white streaks observed The aggregate is a mass formed by the aggregation of powder (the powder itself does not mean an aggregate). Also, the white streak can be confirmed before the aggregate is formed (aggregate precursor).

[0073] Formulation stability (stability over time) The bulk condition of each sample was visually inspected after storage at 40°C for two months. ◎: No change in condition observed ○: Slight change in condition △: A slight change in condition is observed. ×: A clear change in condition is observed The change in state means separation of the oil phase and the water phase, or the formation of aggregates or white streaks.

[0074] Adhesion to skin A panel of 20 experts conducted a usability test on each sample, and each panelist rated it on a four-point scale using the absolute criteria below. The average score was calculated from the total scores of all panelists, and judged according to the following criteria. Specifically, an appropriate amount of each sample was applied to the skin, and the strength of the cosmetic's adhesion when applied was evaluated. (Absolute Standard) 3: Very sensitive 2: Feel 1: Somewhat 0: No feeling (Judgment criteria) ◎: 2.5 points or more ○: 2 points or more and less than 2.5 points △: 1 point or more but less than 2 points ×: Less than 1 point

[0075] Makeup retention A panel of 20 experts conducted a usability test on each sample, and each panel member rated it on a four-point scale using the absolute criteria below. The average score was calculated from the total scores of all panel members, and judged according to the following criteria. Specifically, an appropriate amount of each sample was applied to the skin, and 8 hours after application, the makeup wear (= duration of makeup effect) was evaluated as to whether it was sufficient. (Absolute Standard) 3: The makeup lasts well, and the effects of the makeup last for a long time. 2: The makeup lasts well and the effect is noticeable, but it is slightly insufficient. 1: The makeup lasts a little long, and the makeup effect does not last very long. 0: The makeup lasts very poorly and the makeup effect does not last long enough (Judgment criteria) ◎: 2.5 points or more ○: 2 points or more and less than 2.5 points △: 1 point or more but less than 2 points ×: Less than 1 point

[0076] result The water-in-oil emulsion cosmetics of Examples 1 to 27 were rated as fair or better (Fair, Good or Excellent) with no poor results in all evaluation items (powder dispersibility (uniformly dispersed state), formulation stability (stability over time), adhesion to skin, and cosmetic durability), indicating that good water-in-oil emulsion cosmetics were obtained. On the other hand, Comparative Examples 1 to 6 had poor powder dispersibility. Furthermore, Comparative Examples 1 to 6 also had relatively low formulation stability. Furthermore, the results of Example 1, Comparative Examples 1 and 7 suggested that while the inclusion of powder tends to decrease formulation stability, the incorporation of component (A) could improve formulation stability.

[0077] Example (Formulation Example) The following examples were produced as water-in-oil emulsion compositions. In the following examples, the content means the blending ratio (mass%), and the "balance" means the amount that makes the total amount 100 mass%. When a surface-treated powder is used as component (C), the amount of component (C) is basically the amount including the surface-treated component. However, when component (C) (or component (C1)) surface-treated with component (A) is used, the amount of component (C) (or component (C1)) is the amount excluding component (A), and the excluded component (A) is added to the total amount of component (A).
