[Effects of the Invention]

[0007] The powder-containing cosmetic composition of the present invention exhibits good powder dispersibility and excellent makeup retention. [Modes for carrying out the invention]

[0008] The following describes embodiments for carrying out the present invention.

[0009] The powder-containing cosmetic composition of the present invention contains the following (A) to (C) as essential components. (A) Particulate metal oxide (B) Ester compounds of polyglycerin with an average degree of polymerization of 2 to 20 and at least one monovalent carboxylic acid or its derivative and at least one divalent carboxylic acid or its derivative. (C) One or more silicone polymers selected from trimethylsiloxysilicate, polymethylsilsesquioxane, polypropylsilsesquioxane, (acrylates / dimethicone) copolymer, (dimethicone / vinyl dimethicone) crosspolymer, (dimethicone / phenylvinyl dimethicone) crosspolymer, dimethicone crosspolymer, (vinyl dimethicone / methicone silsesquioxane) crosspolymer, (diphenyl dimethicone / vinyl diphenyl dimethicone / silsesquioxane) crosspolymer, (vinyl dimethicone / lauryl dimethicone) crosspolymer, and phenylpropyldimethylsiloxysilicate.

[0010] In this invention, fine particles refer to particles with an average particle diameter in the range of approximately 10 nm to 200 nm. The average particle diameter is the average particle diameter based on volume and can be measured using a laser diffraction / scattering particle size distribution analyzer. Examples of fine particle metal oxides include fine particle titanium oxide, fine particle zinc oxide, fine particle zirconium oxide, and fine particle cerium oxide. One or two selected from fine particle titanium oxide and fine particle zinc oxide are preferred due to their excellent ultraviolet scattering effect, and fine particle zinc oxide is particularly preferred due to its excellent UVA blocking effect. Furthermore, the shape of the fine particle metal oxide is not particularly limited and may be hydrophilic or hydrophobic.

[0011] Fine-particle titanium dioxide can be used without particular restrictions as long as it is the type used in ordinary powder-containing cosmetics. The shape of the fine-particle titanium dioxide is not particularly limited. Furthermore, as for the particle size of the fine-particle titanium dioxide, for example, those with an average particle size of 100 nm or less, and more preferably 80 nm or less, are used. The lower limit of the average particle size of fine-particle titanium dioxide is not particularly limited, but is usually around 30 nm. Fine-particle titanium dioxide can be manufactured by conventional methods such as the sulfuric acid method or the chlorine method, and commercially available products can also be used. Examples of commercially available fine-particle titanium dioxide include the SIV series, TTO-55 series, TTO-S series (all manufactured by Ishihara Sangyo Co., Ltd.), MT-100TV, MT-500V, MT-01 (all manufactured by Teika Co., Ltd.).

[0012] Fine-particle titanium dioxide can be used with its surface treated to be hydrophilic or hydrophobic as needed. Examples of hydrophilic treatment methods include surface treatments such as treatment with polyhydric alcohols such as glycerin and hyaluronic acid. Examples of hydrophobic treatment methods include surface treatments such as treatment with fluorine compounds, silicone, alkyl, alkylsilane, metal soap, water-soluble polymer, amino acid, N-acyl amino acid, lecithin, organic titanate, polyol, acrylic resin, methacrylic resin, and urethane resin.

[0013] Fine-particle titanium dioxide and / or surface-treated fine-particle titanium dioxide can be directly incorporated into powder-containing cosmetics, but if necessary, it can be used coated on the surface of other powders such as plate-shaped powders like talc, mica, and sericite, or silica and spherical powders. By coating plate-shaped or spherical powders with fine-particle titanium dioxide, aggregation of the fine-particle titanium dioxide is reduced, and a high UV protection effect can be obtained. Furthermore, by coating plate-shaped or spherical powders with fine-particle titanium dioxide, the characteristic frictional feel of fine-particle titanium dioxide is reduced, resulting in a cosmetic with a good feel.

[0014] Fine-particle titanium dioxide and / or surface-treated fine-particle titanium dioxide can be incorporated directly into powder-containing cosmetics, but they can also be used in which they are pre-dispersed in oils such as silicone oil and hydrocarbon oil, or in aqueous components.

[0015] The zinc oxide particles can be used without particular restrictions as long as they are the type commonly used in powder-containing cosmetics. The shape of the zinc oxide particles is not particularly limited. Examples of commercially available zinc oxide particles include FINEX-25, FINEX-30, FINEX-50 (all manufactured by Sakai Chemical Industry Co., Ltd.), MZ-300, and MZ-500 (both manufactured by Teika Co., Ltd.).

[0016] The zinc oxide particles can be used with their surfaces hydrophilized or hydrophobic, as needed. Examples of hydrophilic treatment methods include surface treatments such as treatment with polyhydric alcohols such as glycerin and hyaluronic acid. Examples of hydrophobic treatment methods include surface treatments such as treatment with fluorine compounds, silicone, alkyl, alkylsilane, metal soap, water-soluble polymer, amino acid, N-acyl amino acid, lecithin, organic titanate, polyol, acrylic resin, methacrylic resin, and urethane resin.

[0017] Fine particle zinc oxide and / or its surface-treated fine particle zinc oxide can be directly incorporated into a powder-containing cosmetic. However, if necessary, those coated on the surface of plate-shaped powders such as talc, mica, sericite, or other powders such as silica and spherical powders can be used. By coating fine particle titanium oxide on plate-shaped powders or spherical powders, the aggregation of fine particle titanium oxide is reduced, and a high ultraviolet ray protection effect can be obtained. Also, by coating fine particle titanium oxide on plate-shaped powders or spherical powders, the crunchiness in the feel of use peculiar to fine particle titanium oxide is reduced, and a cosmetic with a good feel of use can be obtained.

[0018] Fine particle zinc oxide and / or its surface-treated fine particle zinc oxide can be directly incorporated into a powder-containing cosmetic as a powder. However, those preliminarily dispersed in an oil agent such as silicone oil or hydrocarbon oil, or in an aqueous component can also be used.

[0019] The above-mentioned fine particle metal oxides may be used alone or in combination of two or more. It is preferable to incorporate the fine particle metal oxide in an amount of 0.1 to 30% by mass as the fine particle metal oxide based on the total amount of the powder-containing cosmetic. When the fine particle metal oxide is 0.1% by mass or more, the ultraviolet ray shielding effect by the fine particle metal oxide can be more expected. When the fine particle metal oxide is 30% by mass or less, the feel of use can be made more preferable.

[0020] In the present invention, as (B), an ester compound of polyglycerin having an average degree of polymerization of 2 to 20, at least one monovalent carboxylic acid or its derivative, and at least one divalent carboxylic acid or its derivative is used as an essential component.

[0021] The polyglycerin that constitutes the ester compound is not particularly limited as long as it is a polyglycerin with an average degree of polymerization of 2 to 20. For example, diglycerin, triglycerin, tetraglycerin, pentaglycerin, hexaglycerin, heptaglycerin, octaglycerin, nonaglycerin, decaglycerin, hexadecaglycerin, octadecaglycerin, eicosadecatetra glycerin, etc. can be mentioned. Among these, tetraglycerin, pentaglycerin, hexaglycerin, heptaglycerin, octaglycerin, nonaglycerin, and decaglycerin are preferred. More preferably, it is decaglycerin. The average degree of polymerization can be calculated from the hydroxyl value of each polyglycerin.

[0022] Examples of the monovalent carboxylic acid include acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, 2-ethylhexanoic acid, isononanoic acid, capric acid, lauric acid, myristic acid, isomyristic acid, palmitic acid, isopalmitic acid, stearic acid, isostearic acid, ricinoleic acid, oleic acid, linoleic acid, linolenic acid, arachidic acid, isoarachidic acid, behenic acid, erucic acid, etc. Among these, isostearic acid is preferred.

[0023] Examples of the divalent carboxylic acid include oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, dimethyloctadecanedioic acid, phthalic acid, isophthalic acid, terephthalic acid, maleic acid, dimer acid, tetrahydrophthalic acid, octenyl succinic acid, dodecenyl succinic acid, etc. Among these, succinic acid is preferred.

[0024] Further, as derivatives of the monovalent carboxylic acid or the divalent carboxylic acid, acid anhydrides and acid halides of the above-mentioned carboxylic acids may be used.

[0025] There is no particular limitation on the esterification rate of the polyglycerin ester, but from the viewpoint of the dispersibility of the dispersion, the esterification rate is preferably 75 to 100%.

[0026] There are no particular restrictions on the molar ratio of monovalent carboxylic acid to divalent carboxylic acid, but from the viewpoint of dispersion dispersibility, a molar ratio (monovalent carboxylic acid / divalent carboxylic acid) of 99.99 / 0.01 to 0.01 / 99.99 is preferred. More preferably, it is 95.0 / 5.0 to 50 / 50.

[0027] As a method for synthesizing such ester compounds, commonly used esterification reactions can be employed, specifically, the methods described in paragraphs

[0040] of International Publication No. 2016 / 08027 can be cited.

[0041] The amount of such silicone polymer included is not particularly limited, but it is preferably 0.05 to 10% by mass, and more preferably 0.5 to 5% by mass, relative to the total amount of powder-containing cosmetic.

[0042] The powder-containing cosmetic composition of the present invention exhibits the effect of improving makeup longevity by incorporating (C).

[0043] Next, we will describe optional components that may be incorporated into the powder-containing cosmetic composition of the present invention.

[0044] The powder-containing cosmetic composition of the present invention may contain solid spherical borosilicate particles. The average particle size of solid spherical borosilicate particles is preferably 0.1 μm or more, more preferably 1 μm or more, even more preferably 5 μm or more, and even more preferably 7 μm or more. Furthermore, the average particle size of solid spherical borosilicate particles is preferably 20 μm or less, more preferably 15 μm or less, and even more preferably 13 μm or less. For example, from the viewpoint of reducing stickiness, the average particle size of solid spherical borosilicate particles is preferably 1 to 20 μm, more preferably 5 to 15 μm, and even more preferably 7 to 13 μm. The average particle size of solid spherical borosilicate particles can be measured as the average particle size by number average using the principle of microscopy, in accordance with the shape of the powder particles.

[0045] In solid spherical borosilicate particles, the borosilicate may be an alkali metal salt such as Na or K, an alkaline earth metal salt such as Mg or Ca, an Al salt, or a combination of these salts. Preferably, it is sodium borosilicate, calcium borosilicate, aluminum borosilicate, borosilicate (Ca / Na), borosilicate (Ca / Al), and more preferably borosilicate (Ca / Na). Solid spherical borosilicate particles are labeled as calcium sodium borosilicate (Ca / Na) or calcium aluminum borosilicate (Ca / Al) in cosmetic labeling names (INCI names). In the present invention, any of these labeling names for solid spherical borosilicate particles may be used, but the use of calcium sodium borosilicate is more preferable.

[0046] When solid spherical borosilicate particles are incorporated, the amount is not particularly limited, but it is preferably 0.01% by mass or more, more preferably 0.1% by mass or more, and even more preferably 1% by mass or more, relative to the total amount of powder-containing cosmetic. Furthermore, while the amount of solid spherical borosilicate particles is not particularly limited, it is preferably 30% by mass or less, more preferably 20% by mass or less, and even more preferably 10% by mass or less, relative to the total amount of powder-containing cosmetic. For example, the amount of solid spherical borosilicate particles blended is preferably 0.01 to 30% by mass, more preferably 0.1 to 20% by mass, and even more preferably 1 to 10% by mass, based on the total amount of the powder-containing cosmetic. For example, in powder-containing cosmetics with an aqueous or oil-based dosage form, the amount of solid spherical borosilicate particles is more preferably 0.01 to 10% by mass, based on the total amount of the powder-containing cosmetic. Furthermore, in powder-containing cosmetics with a powder or solid dosage form, the amount of solid spherical borosilicate particles is more preferably 0.1 to 20% by mass, based on the total amount of the powder-containing cosmetic.

[0047] The solid spherical borosilicate particles may be untreated, or they may be treated to be hydrophilic or hydrophobic.

[0048] When the solid spherical borosilicate particles of the present invention are incorporated into a powder-containing cosmetic composition, using zinc oxide-coated solid spherical borosilicate particles allows them to exhibit a sebum-solidifying effect and improve the longevity of the makeup.

[0049] The zinc oxide used in the zinc oxide-coated solid spherical borosilicate particles of the present invention is not particularly limited as long as it can be incorporated into powder-containing cosmetics. The shape of the zinc oxide is not particularly limited. From the viewpoint of sebum solidification ability, the average particle diameter of zinc oxide is preferably 10 to 200 nm, more preferably 15 to 100 nm, and even more preferably 15 to 50 nm. The average particle diameter of zinc oxide is the average particle diameter based on volume and can be measured by a laser diffraction / scattering particle size distribution analyzer.

[0050] Zinc oxide-coated solid spherical borosilicate particles can be obtained, for example, by coating solid spherical borosilicate particles with zinc oxide powder. Fine-particle zinc oxide powder is preferred. While untreated zinc oxide can be used as is, it is preferable to use zinc oxide that has undergone hydrophobic treatment. The hydrophobic treatment agent is not particularly limited, and examples include dimethicone, methylhydrogenpolysiloxane, and metal soaps. Among these hydrophobic treatment agents, dimethicone is preferred. The amount of hydrophobic treatment agent coating should be sufficient to hydrophobicize the zinc oxide. Specifically, the mass ratio of zinc oxide to hydrophobic treatment agent is preferably 85:15 to 99:1, and more preferably 90:10 to 98:2.

[0051] In the zinc oxide-coated solid spherical borosilicate particles used in the powder-containing cosmetic composition of the present invention, the amount of zinc oxide coating is preferably 0.01 parts by mass or more, and more preferably 0.05 parts by mass or more, per 1 part by mass of solid spherical borosilicate particles. Furthermore, the amount of zinc oxide coating is preferably 2 parts by mass or less, and more preferably 1.5 parts by mass or less, per 1 part by mass of solid spherical borosilicate particles. Within this range, the sebum solidification ability can be further enhanced, and sebum breakdown can be further prevented. For every 1 part by mass of solid spherical borosilicate particles, the amount of zinc oxide coating is preferably 0.01 to 2 parts by mass, and more preferably 0.05 to 1.5 parts by mass.

[0052] Various previously known methods can be used to coat solid spherical borosilicates with zinc oxide. For example, physicochemical mixing and grinding methods (dry or wet) and chemical deposition methods can be used. From the viewpoint of the sebum-solidifying ability of zinc oxide-coated solid spherical borosilicate particles, a dry mixing and grinding method is preferably used.

[0053] The powder-containing cosmetic composition of the present invention, by containing the above-mentioned solid spherical borosilicate particles, preferably zinc oxide-coated solid spherical borosilicate particles, has sebum-solidifying ability and can exhibit excellent makeup-holding effects.

[0054] In the powder-containing cosmetic composition of the present invention, the amount of solid spherical borosilicate particles to be incorporated is not particularly limited, but is preferably 0.01% by mass or more, more preferably 0.1% by mass or more, and even more preferably 1% by mass or more, relative to the total amount of the powder-containing cosmetic composition. Furthermore, the amount of solid spherical borosilicate particles to be incorporated is not particularly limited, but is preferably 20% by mass or less, more preferably 15% by mass or less, and even more preferably 10% by mass or less, relative to the total amount of the powder-containing cosmetic composition.

[0055] The powder-containing cosmetic composition of the present invention may contain an organic ultraviolet absorber.

[0056] The type of organic UV absorber is not particularly limited, and known organic UV absorbers can be used without restriction. Examples of such known organic UV absorbers include cinnamic acid derivatives such as 2-ethylhexyl paramethoxycinnamate, isopropyl methoxycinnamate, and isoamyl methoxycinnamate; PABA derivatives such as para-aminobenzoic acid (hereinafter abbreviated as "PABA"), ethyl PABA, ethyl-dihydroxypropyl PABA, ethylhexyl-dimethyl PABA, and glyceryl PABA; salicylic acid derivatives such as homosalate, ethylhexyl salicylate, dipropylene glycol salicylate, and TEA salicylate; and benzophenone- 1. Benzophenone derivatives such as benzophenone-2, benzophenone-3 or oxybenzone, benzophenone-4, benzophenone-5, benzophenone-6, benzophenone-8, benzophenone-9, benzophenone-12; benzylidene derivatives such as 3-benzylidene, 4-methylbenzylidene, benzylidene sulfonic acid, benzalkonium methosulfate, terephthalylidene disulfonic acid, polyacrylamide methylbenzylidene; anisotriazepam Triazine derivatives such as diethylhexylbutamide triazone, 2,4,6-tris(diisobutyl-4'-aminobenzalmalonate)-s-triazine, 2,4-bis-[{4-(2-ethylhexyloxy)-2-hydroxy}-phenyl]-6-(4-methoxyphenyl)-1,3,5-triazine, 2,4,6-tris[4-(2-ethylhexyloxycarbonyl)anilino]-1,3,5-triazine; phenylbenzimidazole derivatives such as phenyldibenzimidazole disodium tetrasulfonate; Phenylbenzotriazole derivatives such as lometrizole trisiloxane and methylenebis(benzotriazolyltetramethylbutylphenol); anthranil derivatives such as menthyl anthranilate; imidazoline derivatives such as dimethoxybenzylidene oxoimidazolidine propionate 2-ethylhexyl; benzalmalonate derivatives such as polyorganosiloxanes having a benzalmalonate functional group; 4,4-diarylbutadiene derivatives such as 1,1-dicarboxy(2,2'-dimethylpropyl)-4,4-diphenylbutadiene;Examples include octocrylene, 2-[4-(diethylamino)-2-hydroxybenzoyl]hexyl benzoate, and 4-tert-butyl-4'-methoxydibenzoylmethane. Organic UV absorbers can be used individually or in combination of two or more.

[0057] When incorporating organic UV absorbers, the preferred amount is 1 to 20% by mass. Below 1% by mass, sufficient sun protection cannot be obtained, while above 20% by mass, it negatively affects the user experience, such as stickiness and increased primary skin irritation.

[0058] In addition to the essential and optional components mentioned above, the powder-containing cosmetic composition of the present invention may appropriately contain, as needed, aqueous components, oily components, other moisturizers, pigments, surfactants, thickeners, beauty ingredients, fragrances, polymers, antibacterial and antifungal agents, alcohols, powders, scrubbing agents, bio-derived components, and the like, which are commonly used in powder-containing cosmetics.

[0059] The dosage form of the powder-containing cosmetic of the present invention is not particularly limited, and dosage forms such as loose-type powder-containing cosmetic, solid-type oily powder-containing cosmetic, paste-type oily powder-containing cosmetic, liquid-type oily powder-containing cosmetic, water-in-oil emulsion-type powder-containing cosmetic, water-based powder-containing cosmetic, and aerosol can be used. Due to the dispersion characteristics of the ester compound of component (B), it is preferably used in solid-type oily powder-containing cosmetic, paste-type oily powder-containing cosmetic, liquid-type oily powder-containing cosmetic, and water-in-oil emulsion-type powder-containing cosmetic, and among these, water-in-oil emulsion-type powder-containing cosmetic is most preferable.
