Description

[Technical Field]

[0001] The present invention relates to a cosmetic composition. [Background technology]

[0002] Silica is sometimes added to cosmetic compositions such as foundations (see JP 2011-213662 A and JP 2021-107372 A). Because silica has the property of scattering light, when a cosmetic composition containing silica is applied to the skin, it provides a blurring effect, making pores, skin irregularities, and the like underneath the cosmetic composition less visible. Summary of the Invention [Problem to be solved by the invention]

[0003] However, the adhesive strength between silica particles or between silica and skin is poor, and therefore, cosmetic compositions containing silica are unlikely to form a film on the skin, making it difficult to maintain makeup for a long time. That is, it is difficult to simultaneously improve blending effect and durability. In addition, when a large amount of film-forming agent is used to facilitate the formation of a film in a cosmetic composition containing silica, the cosmetic composition feels sticky to the touch, and a comfortable finish is not achieved, which is undesirable.

[0004] Therefore, an object of the present invention is to provide a cosmetic composition that can achieve an excellent blurring effect, a long-lasting effect, and a comfortable finish. [Means for solving the problem]

[0005] The present invention provides a cosmetic composition comprising (A) porous silica treated with dextrin esterified with a fatty acid (also referred to as "dextrin fatty acid ester" in the present disclosure), (B) a volatile hydrocarbon oil, (C) a hydrophobically treated color pigment, and (D) a surfactant.

[0006] One of the features of the cosmetic composition of the present invention is that it contains component (A). It is believed that the excellent blurring effect, which reduces the visibility of skin irregularities such as wrinkles and pores, is primarily due to this feature. Because the porous silica of component (A) is treated with a dextrin fatty acid ester, the silica particles do not come into direct contact with each other, which is believed to solve the above-mentioned adhesion problem. As a result, the cosmetic composition of the present invention is likely to form a film easily when applied to the skin, and is believed to be able to achieve a long-lasting effect even without adding a large amount of a film-forming agent. In this case, it is also possible to avoid the cosmetic composition from feeling sticky. For these reasons, it is believed that the cosmetic composition of the present invention containing component (A) can simultaneously achieve an excellent blurring effect and a long-lasting effect while achieving a comfortable finish.

[0007] As described above, it is important that the porous silica is treated with a dextrin fatty acid ester, and therefore it is not sufficient for the dextrin fatty acid ester to simply coexist with the porous silica in the cosmetic composition. "Porous silica treated with a dextrin fatty acid ester" means that at least a portion of the surface and / or interior of the porous silica is coated with the dextrin fatty acid ester.

[0008] The present invention also provides the above composition, wherein the dextrin fatty acid ester is an ester of dextrin and a branched-chain fatty acid.

[0009] The present invention also provides the above composition, wherein the fatty acid has 16 to 22 carbon atoms.

[0010] The present invention also provides the above composition, wherein the fatty acid is at least one selected from the group consisting of isopalmitic acid, isostearic acid, isoarachidic acid, and 18-methyleicosanoic acid.

[0011] The present invention also provides the above composition, wherein the dextrin fatty acid ester is dextrin isostearate.

[0012] The present invention also provides the above composition, wherein the particle size of the porous silica is 1 to 20 μm.

[0013] The present invention relates to a method for producing porous silica having a specific surface area of ​​100 to 1000 m 2 The composition also provides the above composition, wherein the amount of hydroxybenzoates is 1 / g.

[0016] The present invention also provides the above composition, wherein the oil absorption of the porous silica is 50 to 500 ml / 100 g.

[0017] The present invention also provides the above composition, wherein the content of component (A) is 1 to 25 mass %, preferably 1 to 20 mass %, based on the total mass of the composition.

[0018] The present invention also provides the above composition, wherein component (B) comprises a volatile straight-chain hydrocarbon having 9 to 15 carbon atoms.

[0019] The present invention also provides the above composition, wherein the particle size of the color pigment is less than 1 μm.

[0020] The present invention also provides the above composition, wherein component (D) comprises a nonionic surfactant having an HLB of 6 or less.

[0021] The present invention also provides the composition, wherein the composition further comprises at least one solvent selected from the group consisting of water and alcohol.

[0022] The present invention also provides the above composition, wherein the content of component (B) is 1 to 80% by mass, preferably 1 to 70% by mass, based on the total mass of the composition.

[0024] The present invention also provides the above cosmetic composition, wherein the cosmetic composition comprises, based on the total amount of the composition, 1 to 25% of component (A), 1 to 80% of component (B), 1 to 40% of component (C), and 1 to 25% of component (D).

[0027] According to the present invention, a cosmetic composition is provided that can achieve an excellent blurring effect, a long-lasting effect, and a comfortable finish. DETAILED DESCRIPTION OF THE INVENTION

[0028] A cosmetic composition according to one embodiment includes (A) porous silica treated with a dextrin fatty acid ester. The dextrin fatty acid ester may be an esterification product of dextrin and a straight-chain fatty acid or a branched-chain fatty acid. The dextrin fatty acid ester is preferably an esterification product of dextrin and a branched-chain fatty acid. When the fatty acid forming the ester with dextrin is a branched-chain fatty acid, it is believed that the cosmetic composition can exhibit better flexibility derived from the branched chain.

[0029] The dextrin fatty acid ester can be represented, for example, by the following general formula (Ia) or (Ib): In the following general formula, A is a residue obtained by removing an OH group from a fatty acid, and a part of A may be a hydrogen atom. Note that * indicates a bond.Residues obtained by removing an OH group from fatty acids include residues obtained by removing an OH group from linear saturated fatty acids having 2 to 22 carbon atoms, such as acetic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, and behenic acid; residues obtained by removing an OH group from branched saturated fatty acids having 4 to 14 carbon atoms, such as isobutyric acid, isovaleric acid, 2-ethylbutyric acid, ethylmethylacetic acid, isoheptanoic acid, 2-ethylhexanoic acid, isononanoic acid, isodecanoic acid, isotridecanoic acid, and isomyristic acid; residues obtained by removing an OH group from isopalmitic acid, isostearic acid, isoarachidic acid, and 18-methyl Residues obtained by removing the OH group from branched-chain fatty acids having 16 to 22 carbon atoms, such as cis-4-decenoic (obtusilic) acid, 9-decenoic (caproleic) acid, cis-4-dodecenoic (lindelic) acid, cis-4-tetradecenoic (tsuzunic) acid, cis-5-tetradecenoic (physeteric) acid, cis-9-tetradecenoic (myristoleic) acid, cis-6-hexadecenoic acid, cis-9-hexadecenoic (palmitoleic) acid, cis-9-octadecenoic (oleic) acid, trans-9-octadecenoic (elaidic) acid, cis-11-octadecenoic (albic) acid, Residues obtained by removing an OH group from monoenoic unsaturated fatty acids such as cis-11-eicosene (gondole) acid, cis-17-hexacosene (ximen) acid, and cis-21-triaconten (lumecic) acid; and residues obtained by removing an OH group from linear or branched unsaturated fatty acids having 6 to 30 carbon atoms, such as sorbic acid, linoleic acid, hiragonic acid, punicic acid, α-linolenic acid, γ-linolenic acid, moroctic acid, stearidonic acid, arachidonic acid, EPA, sardine acid, DHA, herring acid, stearic acid, crepenic acid, and ximenynic acid. and residues obtained by removing an OH group from saturated or unsaturated fatty acids having 6 to 30 carbon atoms and having a cyclic structure in at least a part of the basic skeleton, such as 9,10-methylene-9-octadecenoic acid, aleprilic acid, alepuric acid, golric acid, α-cyclopentylic acid, α-cyclohexylic acid, α-cyclopentylethyl acid, α-cyclohexylmethyl acid, ω-cyclohexylic acid, 5(6)-carboxy-4-hexyl-2-cyclohexene-1-octanoic acid, malvalic acid, sterculic acid, hydnocarpic acid, and shormu-glic acid. The fatty acid that forms an ester with dextrin is preferably a branched-chain saturated fatty acid having 16 to 22 carbon atoms. [ka]

[0030] Preferred examples of esters of dextrin and fatty acids include dextrin myristate, dextrin palmitate, dextrin palmitate / 2-ethylhexanoate, dextrin stearate, dextrin palmitate / stearate, dextrin oleate, dextrin isopalmitate, dextrin isostearate, dextrin isoarachidate, and dextrin 18-methyleicosanoate, with dextrin isostearate being more preferred.

[0031] The porous silica may be further treated with a hydrophobizing agent other than the dextrin fatty acid ester. The other hydrophobizing agent may be at least one selected from the group consisting of silicone compounds, fluorine compounds, oils, fats and oils, phospholipids, amino acids, higher alcohols, waxes, polymers, and resins. The porous silica may be further treated with a hydrophobizing agent other than the oils, silicones, and fluorine compounds among the other hydrophobizing agents described above. The porous silica may not be treated with ceramides. The porous silica may not be treated with a silicone-acrylic copolymer.

[0032] With respect to component (A), the mass of the portion derived from the hydrophobizing agent may be 1 to 15 mass%, 1 to 10 mass%, 1 to 5 mass%, 2 to 15 mass%, 2 to 10 mass%, 2 to 8 mass%, 2 to 5 mass%, 3 to 15 mass%, 3 to 10 mass%, 3 to 8 mass%, or 3 to 5 mass%, based on the total mass of the hydrophobized porous silica. When the content of the hydrophobizing agent is within these ranges, the dispersibility of component (A) is improved, and the emulsion stability, covering power, and durability of the cosmetic composition can be further improved. In this specification, the covering effect may refer to an optical covering effect. When the content of the hydrophobizing agent is within these ranges, the surface of the porous silica can be sufficiently covered, thereby suppressing a powdery feel.

[0033] Porous silica is classified as a body pigment. The term "body pigment" is used to clearly distinguish it from color pigments, which are added primarily for the purpose of coloring cosmetic compositions, etc. Body pigments are sometimes called "fillers," and are substances that form the framework of, for example, powder foundations.

[0034] Because porous silica has pores, it is excellent at absorbing sebum, sweat, etc., and can prevent an oily finish. Therefore, porous silica is preferable to non-porous silica. The shape of the porous silica may be spherical. When the porous silica is spherical, the cosmetic composition feels smoother when applied to the skin. When the porous silica is spherical, contact between the porous silica particles or between the porous silica and the skin occurs at points rather than on a surface, making it difficult for cosmetic compositions containing silica to form a film on the skin, making it particularly difficult to maintain makeup for a long time. However, according to the present invention, even if the porous silica is spherical, a film can be formed without any problems, making it possible to maintain makeup for a long time. Therefore, the cosmetic composition of the present invention does not need to contain a large amount of a film-forming agent, but this does not prevent the addition of a certain amount of a film-forming agent as long as the effects of the present invention are obtained.

[0035] The number-average particle size of the porous silica may be 1 to 20 μm, 2 to 15 μm, 4 to 12 μm, or 3 to 6 μm. When the number-average particle size of the porous silica is within these ranges, a better blending effect, a longer-lasting effect, and a more comfortable finish can be obtained. In addition, when the number-average particle size of the porous silica is within these ranges, excellent covering power can be obtained, and a beautiful makeup effect can be obtained when the cosmetic composition is applied to the skin.

[0036] The specific surface area of ​​porous silica is 100 to 1000 m 2 / g, 200-1000m 2 / g, 300-1000m 2 / g, 400-1000m 2 / g, 500-1000m 2 / g or 600-900m 2 / g. The specific surface area of ​​porous silica can be determined by measuring the amount of nitrogen adsorbed to the porous silica and analyzing it using the BET method. When the specific surface area of ​​porous silica is within these ranges, a better blending effect, a longer-lasting effect, and a more comfortable finish can be obtained. In addition, when the specific surface area of ​​porous silica is within these ranges, excellent covering power can be obtained, and a beautiful makeup effect can be achieved when the cosmetic composition is applied to the skin.

[0037] The pore volume per unit mass of the porous silica may be 0.5 to 5 ml / g, 1 to 5 ml / g, or 1 to 3 ml / g. When the pore volume per unit mass of the porous silica is within these ranges, a better blending effect, a longer-lasting effect, and a more comfortable finish can be obtained. In addition, when the pore volume per unit mass of the porous silica is within these ranges, excellent covering power can be obtained, and a beautiful makeup effect can be obtained when the cosmetic composition is applied to the skin.

[0038] The pore diameter of the porous silica may be 1 to 100 nm, 1 to 80 nm, 1 to 60 nm, 1 to 40 nm, 1 to 20 nm, 1 to 10 nm, or 1 to 5 nm. When the pore diameter of the porous silica is within these ranges, a better blending effect, a longer-lasting effect, and a more comfortable finish can be obtained. In addition, when the pore diameter of the porous silica is within these ranges, excellent covering power can be obtained, and a beautiful makeup effect can be obtained when the cosmetic composition is applied to the skin.

[0039] The oil absorption of the porous silica may be 50 to 500 ml / 100 g, 100 to 400 ml / 100 g, 100 to 300 ml / 100 g, or 100 to 200 ml / 100 g. When the oil absorption of the porous silica is within these ranges, a better blending effect, a longer-lasting effect, and a more comfortable finish can be obtained. In addition, when the oil absorption of the porous silica is within these ranges, excellent covering power can be obtained, and a beautiful makeup effect can be obtained when the cosmetic composition is applied to the skin.

[0040] The content of component (A) may be 1 to 25 mass%, 1 to 20 mass%, 1 to 15 mass%, 1 to 12 mass%, 3 to 25 mass%, 3 to 20 mass%, 3 to 15 mass%, 3 to 12 mass%, 5 to 25 mass%, 5 to 20 mass%, 5 to 15 mass%, 5 to 12 mass%, 7 to 25 mass%, 7 to 20 mass%, 7 to 15 mass%, or 7 to 12 mass%, based on the total mass of the cosmetic composition. When the content of component (A) is within these ranges, a better blending effect, a longer-lasting effect, and a more comfortable finish can be obtained. Additionally, when the content of component (A) is within these ranges, excellent covering power can be obtained, resulting in a beautiful makeup effect when the cosmetic composition is applied to the skin.

[0041] The cosmetic composition according to one embodiment includes a volatile hydrocarbon oil (B). Component (B) may include a volatile linear hydrocarbon oil or a volatile branched hydrocarbon oil. Component (B) may be a polar oil or a non-polar oil.

[0042] "Volatile oil" refers to an oil that loses 4% or more in mass after drying for 60 minutes at 33°C and 55% humidity, as follows: 20 mg of the oil to be tested is weighed onto a 5 cm x 5 cm polymethyl methacrylate (PMMA) plate using a micropipette and precision balance. The oil to be tested is spread over the entire plate with a finger. The plate is then placed in a ventilated room with constant temperature control at 33°C and 55% humidity. This test is performed three times for each oil. The mass loss during drying is measured after 60 minutes. The mass loss value is expressed according to the following equation (1): Mass loss value (%) = (m t0 -m tx )×100 / m t0 ...Equation (1)

[0043] In formula (1), m tx represents the mass of the plate measured 60 minutes after the start of drying, and m t0 represents the mass of the plate measured before drying. Volatile hydrocarbon oils are liquid at room temperature and pressure and can also be considered as oily components that gradually evaporate.

[0044] Component (B) may contain a volatile hydrocarbon oil having 8 to 19 carbon atoms. Preferably, the volatile hydrocarbon oil does not contain oxygen atoms. Component (B) may be at least one selected from the group consisting of branched C8-C16 alkanes (e.g., isoparaffin, isododecane, isodecane, isohexadecane), linear C8-C16 alkanes (e.g., nonane, decane, undecane, dodecane, tridecane, pentadecane, hexadecane), a mixture of C9-C15 alkanes, a mixture of C9-C17 alkanes, a mixture of C10-C14 alkanes, a mixture of undecane and tridecane, a mixture of C15-C19 alkanes, a mixture of C9-C12 alkanes, a mixture of C13-C15 alkanes, a mixture of C12-C14 alkanes, n-dodecane, n-tetradecane, and hydrogenated farnesene. Component (B) preferably comprises a volatile straight-chain hydrocarbon having from 9 to 12 carbon atoms, a volatile straight-chain hydrocarbon having from 13 to 15 carbon atoms, or a mixture thereof.

[0045] Oils with a mass loss value of 4% by mass or more and 30% by mass or less can be called "slightly volatile oils." Slightly volatile oils include isohexadecane, pentadecane, hexadecane, C13-15 alkanes, and C15-19 alkanes. When a cosmetic composition contains a slightly volatile oil, the smoothness of the cosmetic composition tends to be improved.

[0046] Oils with a mass loss value of 30% by mass or more and 80% by mass or less can be called "medium-volatile oils." Medium-volatile oils include undecane, dodecane, tridecane, and C9-12 alkanes (linear). When a cosmetic composition contains a medium-volatile oil, the cosmetic composition tends to have an improved balance between smoothness and adhesion to the skin.

[0047] Oils with a mass loss value of 80% by mass or more are called "highly volatile oils." Highly volatile oils include nonane, decane, isododecane, and C9-12 alkanes (branched chain). When a cosmetic composition contains a highly volatile oil, the cosmetic composition tends to have improved adhesion to the skin.

[0048] The content of component (B) is 1 to 80% by mass, 1 to 70% by mass, 1 to 60% by mass, 1 to 50% by mass, 1 to 40% by mass, 1 to 35% by mass, 1 to 30% by mass, 1 to 2% by mass, based on the total mass of the cosmetic composition. 5% by mass, 1-20% by mass, 5-80% by mass, 5-70% by mass, 5-60% by mass, 5-50% by mass, 5-40% by mass, 5-35% by mass, 5-30% by mass, 5-25% by mass, 5-20% by mass, The content of component (B) may be 10 to 80% by mass, 10 to 70% by mass, 10 to 60% by mass, 10 to 50% by mass, 10 to 40% by mass, 10 to 35% by mass, 10 to 30% by mass, 10 to 25% by mass, 10 to 20% by mass, 15 to 80% by mass, 15 to 70% by mass, 15 to 60% by mass, 15 to 50% by mass, 15 to 40% by mass, 15 to 35% by mass, 15 to 30% by mass, 15 to 25% by mass, or 15 to 20% by mass. When the content of component (B) is within these ranges, a more comfortable finish can be achieved while further improving coverage and durability. Furthermore, when the content of component (B) is within these ranges, the cosmetic composition is less likely to cause a dry, tight feeling, skin irritation, or a stuffy feeling when applied to the skin, making it more preferable in terms of usability.

[0049] The cosmetic composition contains (C) a hydrophobically treated color pigment.

[0050] At least a portion of the surface and / or interior of the color pigment may be coated with at least one selected from the group consisting of dextrin fatty acid esters, silicone compounds, amino acid derivatives, organic titanates, fluorine compounds, metal soaps, and glycerin fatty acid esters.

Titanium dioxide is known as a white pigment, and iron oxide is known as a red, yellow, or black colored pigment. By appropriately combining these, the desired color tone can be adjusted. In addition to component (C), the cosmetic composition may contain, as a pigment, a colorant that has not been hydrophobized. Specifically, the cosmetic composition may contain pigments exemplified as color pigments used in component (C) that have not been hydrophobized, as well as organic pigments such as D&C RED No. 7 and D&C RED No. 6.

When the content of the polyol having 1 to 8 carbon atoms is within these ranges, the moisturizing effect can be further enhanced without destabilizing the emulsified state.

[0069] The alcohol may contain a monool having 1 to 3 carbon atoms. Examples of the monool having 1 to 3 carbon atoms include ethanol, 1-propanol, and 2-propanol (isopropanol).

[0070] The content of the monool having 1 to 3 carbon atoms may be 1 to 20 mass%, 1 to 10 mass%, or 1 to 5 mass%, based on the total mass of the cosmetic composition. When the content of the monool having 1 to 3 carbon atoms is within these ranges, a uniform film is easily formed, and the covering power and durability can be further improved.

[0071] The content of the aqueous phase component may be 10 to 80 mass%, 15 to 70 mass%, 20 to 60 mass%, 25 to 50 mass%, 30 to 40 mass%, or 30 to 35 mass%, based on the total mass of the cosmetic composition. When the content of the aqueous phase component is within these ranges, the freshness and covering power when the cosmetic composition is applied to the skin are further improved, and the stability of the cosmetic composition is further improved.

[0072] The cosmetic composition according to one embodiment may contain a non-volatile oil. The term "non-volatile oil" refers to a non-evaporative oil component that is liquid at room temperature (i.e., in the range of 20 to 25°C) and normal pressure (i.e., 1 atmosphere). More specifically, the term "non-volatile oil" refers to an oil component that exhibits a mass loss value (Equation (1)) of less than 4% after drying for 60 minutes at a temperature of 33°C and a humidity of 55% based on the above protocol.

[0073] Examples of non-volatile oils include hydrocarbon oils, higher alcohols, ester oils, and vegetable oils.

[0074] Examples of non-volatile hydrocarbon oils include squalane, liquid paraffin, petrolatum, polybutene, polyisobutene, hydrogenated polyisobutene, hydrogenated polydecene, and olefin oligomers.

[0075] The higher alcohol is an aliphatic monoalcohol having 6 or more carbon atoms, preferably an aliphatic monoalcohol having 12 to 28 carbon atoms. Examples of higher alcohols include octyl alcohol, dodecyl alcohol, oleyl alcohol, octyldodecanol, seryl alcohol, and myricyl alcohol.

[0076] The ester oil is a carboxylic acid ester that is liquid under normal temperature and pressure conditions (for example, in the range of 20 to 25°C and 1 atmospheric pressure) and does not vaporize, and is preferably a carboxylic acid alkyl ester in which the carboxylic acid or alcohol constituting the ester has 8 to 18 carbon atoms. Examples of ester oils include propylene glycol fatty acid esters such as propylene glycol dicaprylate and propylene glycol dicaprate; fatty acid alkyl esters such as ethylhexyl palmitate, isopropyl myristate, 2-octyldodecyl myristate, cetyl 2-ethylhexanoate, coco-caprylic / capric acid, and isononyl isononanoate; carbonates such as dicaprylyl carbonate; tri- or higher fatty acid esters of polyglycerin such as polyglyceryl-2 triisostearate, polyglyceryl-2 tetraisostearate, and polyglyceryl-10 decaisostearate; glyceryl tri-2-ethylhexanoate, glyceryl tribehenate, and tri(caprylic / capric acid) Examples include glycerin tri-fatty acid esters (also called triglyceride oils) such as glyceryl caprate and triheptanoin; benzoic acid derivatives such as diisostearyl malate and alkyl benzoate (C12-15); salicylic acid derivatives such as homosalate and ethylhexyl salicylate; alkyl esters such as coconut caprylate / caprate; and cinnamic acid derivatives such as octyl methoxycinnamate, isopropyl methoxycinnamate, isoamyl methoxycinnamate, cinnoxate, DEA methoxycinnamate, diisopropyl methylcinnamate, glyceryl ethylhexanoate dimethoxycinnamate, and di-(2-ethylhexyl)-4'-methoxybenzalmalonate.

[0077] Examples of vegetable oils include meadowfoam oil, olive oil, camellia oil, coconut oil, macadamia nut oil, rosehip oil, avocado oil, sunflower seed oil, rice bran oil, castor oil, and almond oil.

[0078] The content of the non-volatile oil may be 1 to 70% by mass, 1 to 50% by mass, 1 to 30% by mass, 1 to 20% by mass, 1 to 10% by mass, 1 to 5% by mass, 20 to 70% by mass, 20 to 50% by mass, 20 to 40% by mass, 20 to 30% by mass, 40 to 70% by mass, 40 to 60% by mass, or 40 to 50% by mass, based on the total mass of the cosmetic composition. A non-volatile oil content of 1% by mass or more provides a higher moisturizing effect, and up to at least 70% by mass, the moisturizing effect tends to be even higher as the non-volatile oil content increases. Furthermore, a non-volatile oil content of 70% by mass or less makes the cosmetic layer formed less likely to plasticize, resulting in increased durability. Up to at least 1% by mass, the durability tends to be even higher as the non-volatile oil content decreases.

[0079] A cosmetic composition according to one embodiment may contain an oil-based gelling agent. When the cosmetic composition contains an oil-based gelling agent, components dissolved or dispersed in the cosmetic composition, colloidal particles, and the like may interact with each other to form a three-dimensional higher-order structure (e.g., a three-dimensional network structure). As a result, the fluidity of the composition tends to decrease and the viscosity increases. In other words, the oil-based gelling agent can also be considered a thickener. Increased viscosity can further enhance the covering effect and long-lasting effect, and can also have the effect of suppressing pigment aggregation and / or caking due to long-term storage.

[0080] Examples of oil-based gelling agents include organically modified clay, metal soap, 12-hydroxystearic acid, sugar fatty acid esters, dextrin fatty acid esters such as dextrin palmitate, dextrin myristate, dextrin (palmitate / ethylhexanoate), and dextrin (palmitate / hexyldecanoate), amino acid gelling agents, fine particle silica (particle size less than 1 μm), and mixtures thereof. The oil-based gelling agent preferably contains organically modified clay, and examples of organically modified clay include disteardimonium hectorite and stearalkonium hectorite chloride.

[0081] A cosmetic composition according to one embodiment may contain solid fat. When the cosmetic composition contains solid fat, components, colloidal particles, and the like dissolved or dispersed in the cosmetic composition may form a three-dimensional higher-order structure (e.g., a cardboard structure) having crystals and eutectic structures. As a result, the fluidity of the cosmetic composition tends to decrease, the viscosity tends to increase, and in some cases, the cosmetic composition may completely solidify. In other words, the solid fat can also be considered a thickener. Increased viscosity can further enhance the covering effect and long-lasting effect, and can also have the effect of suppressing pigment aggregation and / or caking due to long-term storage.

[0082] Examples of solid fats include solid higher alcohols such as cetyl alcohol, stearyl alcohol, and behenyl alcohol; hydrocarbon waxes such as polyethylene wax and synthetic wax; vegetable waxes and natural waxes such as carnauba wax, candelilla wax, beeswax, rice wax, and sunflower seed oil (sunflower wax); and fatty acid esters such as palmityl palmitate, stearyl stearate, and behenyl behenate. When the cosmetic composition contains a solid fat, it becomes possible to produce a solid cosmetic composition as one embodiment of the present invention. The content of the solid fat may be 0.5 to 30% by mass, 1 to 20% by mass, or 5 to 15% by mass, based on the total mass of the cosmetic composition. When the content of the solid fat is within these ranges, the emulsified state is more stabilized, resulting in higher coverage and a more comfortable feel. In addition, when the content of the solid fat is 9% by mass or more (e.g., 9 to 20% by mass, 9 to 15% by mass, etc.) based on the total mass of the cosmetic composition, the cosmetic composition can be more easily and stably solidified. Furthermore, the cosmetic composition can be made solid, which makes it more convenient to carry.

[0083] The cosmetic composition according to one embodiment may contain an ultraviolet scattering agent. Examples of the ultraviolet scattering agent include inorganic powder particles such as titanium oxide and zinc oxide, which have not been surface-treated with a hydrophobizing agent. Examples of the ultraviolet scattering agent include fine particle powders having a particle diameter of 100 nm or less, aggregates or coagulations of fine particle powders, and powders having a particle diameter of 100 to 500 nm and having a high ultraviolet scattering effect.

[0084] The cosmetic composition according to one embodiment may further contain spherical powders such as cellulose and starch; stabilizers such as salts; antibacterial agents; antioxidants; fragrances; active ingredients; and the like.

[0085] The cosmetic composition according to one embodiment may be a cosmetic composition that is substantially or completely free of cyclic silicones. When the cosmetic composition is "substantially free" of cyclic silicones, the content of cyclic silicones, based on the total mass of the cosmetic composition, may be 0.01% by mass or less, 0.001% by mass or less, or 0.0001% by mass or less.

[0086] The viscosity of the cosmetic composition according to one embodiment, particularly when the cosmetic composition is in a liquid form, at 25°C may be 150 to 10,000 mPa·s (milliPascal seconds), preferably 1,000 to 8,000 mPa·s, more preferably 1,200 to 6,000 mPa·s, even more preferably 1,400 to 4,000 mPa·s, or most preferably 1,600 to 2,500 mPa·s. The viscosity is measured using a rotational viscometer (for example, Rheolab QC manufactured by Anton Parr) by inserting an ST22-4V-40 spindle into the cosmetic composition contained in a container with an inner diameter of 4.5 cm and maintained at 25°C, and measuring at a rotation speed of 100 rpm for 3 minutes.

[0087] A cosmetic composition according to one embodiment can be obtained by mixing oil-soluble components such as component (A), component (B), component (C), and component (D). If necessary, a water-soluble component can be mixed with the obtained mixture, in which case the obtained cosmetic composition will be a water-in-oil cosmetic composition.

[0088] The cosmetic composition according to one embodiment may be a solid cosmetic composition, a liquid cosmetic composition, a powder cosmetic composition, or a cream cosmetic composition. The cosmetic composition according to another embodiment may be a liquid foundation, a solid foundation, a liquid concealer, a solid concealer, a stick lipstick, a liquid lipstick, or a makeup base. [Example]

[0089] The present invention will be described below using examples, but is not limited to these examples. "NAI surface treatment" refers to surface treatment with disodium stearoyl glutamate. "5% dextrin isostearate surface-treated porous silica" contains 5% by mass of dextrin isostearate and 95% by mass of porous silica based on the total mass of the silica. The values ​​shown in each example or comparative example column add up to 100% by mass. QSP refers to remainder.

[0090] The cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 to 3 were prepared according to the following procedures using the components listed in Tables 1 and 2. The content of each component in Tables 1 and 2 is in mass %. The alcohol in Tables 1 and 2 is ethanol.

[0093] The properties of the cosmetic compositions of the Examples and Comparative Examples were measured according to the following methods.

[0094] The cosmetic compositions of the Examples and Comparative Examples were applied to the facial skin of a professional cosmetics evaluation panel, and the blurring effect, covering power, long-lasting effect, and comfortable finish were evaluated according to the following criteria. "Spots" are areas that are darker in color than the surrounding area due to the deposition of pigments such as melanin on the surface or inside the skin.

[0096] (2) Coverage A: Very good (e.g. redness and blemishes were completely covered) B: Good (e.g. redness and blemishes were almost completely covered.) C: Poor (e.g. redness was covered, but blemishes were still visible.) D: Very bad (e.g. redness and spots were visible)

[0097] (3) Long-lasting effects A: Very good (e.g., makeup didn't come off even after 8 hours) B: Good (Example: My makeup didn't come off even after 4 hours, but it did come off a little after 8 hours.) C: Bad (Example: My makeup came off a little after 4 hours.) D: Very bad (e.g., my makeup was pretty ruined after 4 hours.)

[0098] (4) Comfortable finish A: Very good (e.g., it has a very refreshing feel and is not sticky at all.) B: Good (e.g., very moist and not sticky at all.) C: Poor (e.g., lacks a moist feel and feels sticky) D: Very bad (e.g., no fresh feeling and very sticky)
