[0018] According to one aspect of the present invention, it is possible to provide an oil-in-water type emulsion composition that retains an elastic gel feeling and the moistness peculiar to a gel, and has good adhesion to the skin.

Modes for Carrying Out the Invention

[0019] In this specification, the content of each component in the composition means the total amount of the plurality of substances corresponding to each component in the composition, unless otherwise specified, when there are a plurality of substances corresponding to each component in the composition. Further, the upper and lower limits of the numerical ranges described in this specification can be arbitrarily selected and combined with the numerical values exemplified as the numerical ranges. In addition, the numerical range indicated by using "to" indicates a range including the numerical values described before and after "to" as the minimum value and the maximum value, respectively. Also, (meth)acrylic acid is a general term for acrylic acid, methacrylic acid, and mixtures thereof, and the same applies to other similar expressions (for example, (meth)acrylic acid alkyl esters, etc.).

[0020] The oil-in-water type emulsion composition contains the following components (A), (B), and (C). Component (A) includes a first water-soluble polymer containing a structural unit derived from at least one selected from the group consisting of (meth)acrylic acid and (meth)acrylic acid alkyl esters, and a structural unit derived from at least one selected from the group consisting of polyoxyalkylene alkyl ether itaconate and polyoxyalkylene alkyl ether (meth)acrylate, and at least one water-soluble polymer selected from the group consisting of hydrophobically modified polyether urethanes. Component (B) contains a structural unit derived from at least one selected from the group consisting of (meth)acrylic acid and (meth)acrylic acid alkyl esters, and contains a second water-soluble polymer different from the first water-soluble polymer. Component (C) contains a powder in which polyglyceryl polyisostearate is disposed on the surface.

[0021] The oil-in-water emulsion composition of this embodiment can exhibit good adhesion to the skin while retaining an elastic gel feel and the freshness peculiar to the gel. In addition, it has a good feeling of use with suppressed stickiness and can exhibit good makeup retention. Furthermore, it can exhibit good high-temperature stability. Although the detailed mechanism by which the oil-in-water emulsion composition exhibits such effects is unknown, it can be considered as follows, for example. By including component (B) containing a structure similar to a specific component (A), a state with an elastic gel feel and the freshness peculiar to the gel can be achieved. Furthermore, as the powder component, the presence of component (C) is considered to improve the adhesion to the skin due to the good dispersibility of component (C), and due to the interaction with component (A), it is considered that the good dispersibility is further enhanced and the adhesion to the skin is also further improved.

[0022] The oil-in-water type emulsion composition may be, for example, a gelled cosmetic. The gelled cosmetic exhibits a moderate bouncy texture. The moderate bouncy texture means that when the gelled cosmetic is pressed with a finger to apply a load, an appropriate repulsive force that resists the load is felt along with a deformation of the shape, and when the finger is released, the shape returns to its original state and comes to rest after damped vibration (a bouncy elastic feeling). Also, the gelled cosmetic exhibits a texture such that when the magnitude of the load exceeds a limit, the shape changes greatly and the shape collapses all at once.

[0023] Component (A) The oil-in-water type emulsion composition contains, as component (A), at least one water-soluble polymer compound selected from the group consisting of a first water-soluble polymer and a hydrophobically modified polyether urethane. The oil-in-water type emulsion composition may contain the compound of component (A) alone or in combination of two or more.

[0024] The first water-soluble polymer contains a structural unit (a) derived from at least one monomer selected from the group consisting of (meth)acrylic acid and (meth)acrylic acid alkyl esters, and a structural unit (b) derived from at least one monomer selected from the group consisting of polyoxyalkylene alkyl itaconate and polyoxyalkylene alkyl (meth)acrylate. The first water-soluble polymer is obtained by copolymerizing at least one monomer (a) selected from the group consisting of (meth)acrylic acid and (meth)acrylic acid alkyl esters and at least one monomer (b) selected from the group consisting of polyoxyalkylene alkyl itaconate and polyoxyalkylene alkyl (meth)acrylate. Preferably, it is obtained by copolymerizing a monomer selected from the group consisting of acrylic acid and (meth)acrylic acid alkyl esters and a monomer selected from the group consisting of polyoxyalkylene alkyl itaconate and polyoxyalkylene alkyl (meth)acrylate. The bonding mode of the copolymer is not particularly limited, and it may be any of a block copolymer, a random copolymer, etc. Further, the first water-soluble polymer may further contain a structural unit derived from a monomer other than monomers (a) and (b), and may have a crosslinked structure. When the first water-soluble polymer contains a structural unit derived from another monomer, the content of the structural unit derived from the other monomer may be, for example, greater than 0 mol% and less than 10 mol% with respect to all the structural units, preferably 5 mol% or less, or 1 mol% or less. Here, the contents of the structural unit (a) and the structural unit (b) coincide with the addition amounts of the monomer (a) and the monomer (b) used during production.

[0025] The content ratio of the structural unit (a) to the structural unit (b) in the first water-soluble polymer is not particularly limited, and may be, for example, 0.01 or more and 100 or less as the molar ratio of the structural unit (a) to the structural unit (b).

[0026] Specific examples of the first water-soluble polymer include (meth)acrylic acid / (meth)acrylic acid alkyl ester / (meth)acrylic acid polyoxyethylene alkyl ether copolymer, (meth)acrylic acid / (meth)acrylic acid alkyl ester / itaconic acid polyoxyethylene alkyl ether copolymer, and the like. The first water-soluble polymer may also be a cross-polymer, for example, (meth)acrylic acid / (meth)acrylic acid alkyl ester / (meth)acrylic acid polyoxyethylene alkyl ether cross-polymer, (meth)acrylic acid / (meth)acrylic acid alkyl ester / itaconic acid polyoxyethylene alkyl ether cross-polymer, and the like. The cross-linked structure in the cross-polymer may be formed from, for example, a structural unit derived from (meth)acrylic acid and a cross-linking agent having an allyl group such as pentaerythrityl allyl ether, sucrose allyl ether, or propylene allyl ether.

[0027] The carbon number of the alkyl group in the (meth)acrylic acid alkyl ester, which is one of the monomers forming the constitutional unit (a) of the first water-soluble polymer, may be, for example, from 1 to 22, preferably from 1 to 18, from 1 to 8, or from 1 to 4. Specific examples of the (meth)acrylic acid alkyl ester include methyl (meth)acrylate, ethyl (meth)acrylate, propyl (meth)acrylate, and the like.

[0028] The monomer constituting the constitutional unit (b) of the first water-soluble polymer, itaconic acid polyoxyalkylene alkyl ether or (meth)acrylic acid polyoxyalkylene alkyl ether, is an ester compound of itaconic acid or (meth)acrylic acid and polyoxyalkylene alkyl ether (polyalkylene glycol alkyl ether). The added mole number of the oxyalkylene group in the polyoxyalkylene alkyl ether may be, for example, from 10 to 30, preferably from 12 to 25, from 18 to 25, or from 20 to 25.

[0029] Specific examples of the first water-soluble polymer include (meth)acrylic acid / (meth)acrylic acid alkyl ester / (meth)acrylic acid polyoxyethylene alkyl ether copolymers such as acrylates / methacrylic acid polyoxyethylene (20) cetyl ether copolymer, acrylates / methacrylic acid polyoxyethylene (20) stearyl ether copolymer, acrylates / methacrylic acid polyoxyethylene (25) behenyl ether copolymer; (meth)acrylic acid / (meth)acrylic acid alkyl ester / itaconic acid polyoxyethylene alkyl ether copolymers such as acrylates / itaconic acid polyoxyethylene (20) cetyl ether copolymer, acrylates / itaconic acid polyoxyethylene (20) stearyl ether copolymer; (meth)acrylic acid / (meth)acrylic acid alkyl ester / (meth)acrylic acid polyoxyethylene alkyl ether cross-polymers such as acrylates / methacrylic acid polyoxyethylene (20) stearyl ether cross-polymer; (meth)acrylic acid / (meth)acrylic acid alkyl ester / itaconic acid polyoxyethylene alkyl ether cross-polymers such as acrylates / itaconic acid polyoxyethylene (20) stearyl ether cross-polymer, etc. can be exemplified.

[0030] The first water-soluble polymer of component (A) preferably contains at least one selected from the group consisting of acrylates / methacrylic acid polyoxyethylene stearyl ether copolymer, acrylates / methacrylic acid polyoxyethylene behenyl ether copolymer, acrylates / itaconic acid polyoxyethylene stearyl ether copolymer, and acrylates / itaconic acid polyoxyethylene stearyl ether cross-polymer from the viewpoints of elasticity and adhesiveness. From the viewpoints of elasticity and adhesiveness, it is more preferable to contain at least acrylates / methacrylic acid polyoxyethylene behenyl ether copolymer.

[0031] Examples of commercially available products of acrylates / polyoxyethylene (20) stearyl methacrylate copolymer ((acrylates / methacrylic acid stearless-20) copolymer) include, for example, trade name: Acrylin (registered trademark) 22 (manufactured by Rohm and Haas).

Examples of commercially available products of acrylates / polyoxyethylene (20) stearyl methacrylate cross-polymer include, for example, trade name: Acrylin 88 (manufactured by Rohm and Haas).

[0032] The first water-soluble polymer may be used after being neutralized with a basic substance. The basic substance may be an organic base or an inorganic base. Examples of organic bases include alkanolamines such as monoethanolamine, diethanolamine, triethanolamine, isopropanolamine, diisopropanolamine, and triisopropanolamine; basic amino acids such as L-arginine, etc. Examples of inorganic bases include sodium hydroxide, potassium hydroxide, magnesium hydroxide, etc. These basic substances may be added in an amount sufficient to neutralize the first water-soluble polymer, and the addition amount of the basic substance may be, for example, 20% by mass or more and 90% by mass or less based on the first water-soluble polymer.

[0033] The hydrophobic modified polyether urethane in component (A) may contain, for example, a compound represented by the following formula (I). R 1 {(OR 2 ) k OCONHR 3[NHCOO(R 4 O) n R 5 h} m (I)

[0034] In formula (I), R 1 may be an m-valent hydrocarbon group having 2 to 4 carbon atoms, preferably an alkylene group having 2 to 4 carbon atoms. R 2 and R 4 may each independently be a divalent hydrocarbon group having 2 to 4 carbon atoms, preferably an alkylene group having 2 to 4 carbon atoms. R 3 may be a divalent hydrocarbon group having 1 to 10 carbon atoms which may have a urethane bond, preferably an alkylene group having 4 to 8 carbon atoms which may have a urethane bond. R 5 may be a hydrocarbon group having 8 to 36 carbon atoms, preferably a branched hydrocarbon group having 22 to 26 carbon atoms. m may be a number of 2 or more, preferably 2. h may be a number of 1 or more, preferably 1. k may be a number of 1 to 500, preferably a number of 100 to 300. n may be a number of 1 to 200, preferably a number of 10 to 100 or 10 to 30.

[0035] The hydrophobic modified polyether urethane represented by the above formula (I) is, for example, one or more polyether polyols (also referred to as compound P) represented by R 1 -[(O-R 2 ) k -OH] m (wherein R 1 , R 2 , k, and m are the same as above), and one or more polyisocyanates (also referred to as compound Q) represented by R 3 -(NCO) h+1 (wherein R 3 , and h are the same as above), and HO-(R 4 -O) n -R 5 (wherein R 4 , R 5 ​It can be obtained by reacting with one or more polyether monoalcohols (also referred to as compound R) represented by (wherein m, k, and n are the same as above). The charging ratio of the above three compounds is not particularly limited, but the ratio of the isocyanate group (NCO) derived from the polyisocyanate (Q) to the total number of hydroxyl groups (OH) derived from the polyether polyol (P) and the polyether monoalcohol (R) may be, for example, 0.8 or more and 1.4 or less. For details of the hydrophobically modified polyether urethane represented by the formula (I), reference can be made to, for example, the description in JP-A-2016-88868.

[0036] When reacting compound P, compound Q, and compound R, substances other than the copolymer having the structure of formula (I) may be by-produced. For example, when using a diisocyanate, the main product is an R-Q-P-Q-R type copolymer represented by formula (I), but in addition, R-Q-R type, R-Q-(P-Q) x -P-Q-R type copolymers and the like may be by-produced. In this case, the mixture containing the formula (I) type copolymer can be used in this embodiment without particularly separating the formula (I) type copolymer.

[0037] Further, the hydrophobically modified polyether urethane may contain a compound represented by the following formula (II). H(OR 2 ) k OCONHR 3 [NHCOO(R 4 O) n R 5 (II)

[0038] In formula (II), R 2 , R 3 , R 4 , R 5 , k, and n are the same as those in formula (I).

[0039] As a particularly preferred example, a hydrophobically modified polyether urethane having an INCI name of "(PEG-240 / Decyltetradeceth-20 / HDI) Copolymer (PEG-240 / HDI COPOLYMER BISDECYLTETRADECETH-20 ETHER)" can be mentioned. The said copolymer is commercially available from ADEKA CORPORATION under the trade name "ADEKANOL GT-700".

[0040] The content of component (A) in the oil-in-water emulsion composition may be, for example, 0.005% by mass or more and 25% by mass or less with respect to the oil-in-water emulsion composition. The content of component (A) may preferably be 0.01% by mass or more, 0.05% by mass or more, 0.1% by mass or more, 0.5% by mass or more, or 0.8% by mass or more. The content of component (A) may preferably be 20% by mass or less, 15% by mass or less, 10% by mass or less, 8% by mass or less, 6% by mass or less, 4% by mass or less, or 2% by mass or less. When the content of component (A) is 0.005% by mass or more, good elasticity is imparted and a suitable gel-like shape can be obtained. Also, when it is 0.01% by mass or more, the makeup retention tends to be better. Further, when the content of component (A) is below a predetermined value, the network structure formed by component (A) becomes moderately loose, making it easier to feel freshness after applying the cosmetic, and since the cosmetic film does not become too hard, the makeup retention also tends to be better.

[0041] Component (B) The oil-in-water emulsion composition contains, as component (B), a second water-soluble polymer containing a structural unit derived from at least one selected from the group consisting of (meth)acrylic acid and (meth)acrylic acid alkyl esters. The second water-soluble polymer is a compound different from the first water-soluble polymer and may be a water-soluble polymer compound that does not contain the structural unit (b) contained in the first water-soluble polymer. The oil-in-water emulsion composition may contain the water-soluble polymer compound of component (B) alone or in combination of two or more.

[0042] When the water-in-oil emulsion composition contains component (B), the network structure formed by component (A) becomes moderately loose, making it easier to feel freshness after applying the cosmetic, and the cosmetic film does not become too hard, so the makeup retention tends to be better. This is presumably because, for example, component (B) and component (A) interact with each other to generate an appropriate sense of elasticity and improve freshness more.

[0043] The second water-soluble polymer contains a structural unit derived from at least one selected from the group consisting of (meth)acrylic acid and (meth)acrylic acid alkyl esters. The second water-soluble polymer may be a homopolymer of (meth)acrylic acid or (meth)acrylic acid alkyl ester, or may be a copolymer of (meth)acrylic acid and (meth)acrylic acid alkyl ester. The bonding mode of the copolymer is not particularly limited and may be any of a block copolymer, a random copolymer, etc. Further, the second water-soluble polymer may be a cross-polymer having a cross-linked structure. The cross-linked structure may be formed, for example, from a structural unit derived from (meth)acrylic acid and a cross-linking agent having an allyl group such as pentaerythritol allyl ether, sucrose allyl ether, or propylene allyl ether.

[0044] The number of carbon atoms in the alkyl group portion of the (meth)acrylic acid alkyl ester, which is a monomer constituting the second water-soluble polymer, may be, for example, from 1 to 36. The alkyl group may be either linear or branched. In one embodiment, the number of carbon atoms in the alkyl group may preferably be from 1 to 18, from 1 to 8, or from 1 to 4. In another embodiment, the number of carbon atoms in the alkyl group may preferably be from 8 to 36, from 8 to 32, or from 10 to 30. Specific examples of the (meth)acrylic acid alkyl ester include short-chain alkyl esters such as methyl (meth)acrylate, ethyl (meth)acrylate, and propyl (meth)acrylate; octyl (meth)acrylate, decyl (meth)acrylate, dodecyl (meth)acrylate, tetradecyl (meth)acrylate, cetyl (meth)acrylate, octadecyl (meth)acrylate, icosyl (meth)acrylate, behenyl (meth)acrylate, and triacontanyl (meth)acrylate. The (meth)acrylic acid alkyl ester may be used alone or in combination of two or more.

[0045] The second water-soluble polymer may further contain a structural unit derived from a monomer other than (meth)acrylic acid and (meth)acrylic acid alkyl ester. Examples of other monomers include (meth)acrylic acid alkylamide. That is, the second water-soluble polymer may contain a structural unit derived from at least one selected from the group consisting of (meth)acrylic acid, (meth)acrylic acid alkyl ester, and (meth)acrylic acid alkylamide. The number of carbon atoms in the alkyl group of other monomers may be, for example, from 1 to 10, preferably from 2 to 8, or from 2 to 6. The alkyl group in other monomers may have a substituent. Examples of the substituent include a sulfone group, a carboxy group, and an amino group. Specific examples of other monomers include (meth)acryloyl taurine and (meth)acryloyl dimethyl taurine.

[0046] Specific examples of the second water-soluble polymer include, but are not limited to, acrylate copolymers, (acrylates / alkyl acrylate (C10-30)) cross-polymers, carbomers, sodium acrylate-sodium acryloyldimethyltaurine copolymer, polyvinyl alcohol, etc. The second water-soluble polymer preferably contains at least one selected from the group consisting of acrylate copolymers, carbomers, (acrylates / alkyl acrylate (C10-30)) cross-polymers, and sodium acrylate-sodium acryloyldimethyltaurine copolymer. Note that the (acrylates / alkyl acrylate (C10-30)) cross-polymer includes those referred to as acrylic acid-methacrylic acid alkyl copolymers.

[0047] Examples of commercially available acrylate copolymers include SALCARE SC81UP (manufactured by BASF). Examples of commercially available carbomers include CARBOPOL 980 (manufactured by Lubrizol). Examples of commercially available (acrylates / alkyl acrylate (C10-30)) cross-polymers include CARBOPOL 1382 (manufactured by Lubrizol). Examples of commercially available sodium acrylate-sodium acryloyldimethyltaurine copolymers include SIMULGEL EG QD (manufactured by SEPPIC).

[0048] The second water-soluble polymer may be used after being neutralized with a basic substance. The basic substance may be an organic base or an inorganic base. Examples of organic bases include alkanolamines such as monoethanolamine, diethanolamine, triethanolamine, isopropanolamine, diisopropanolamine, and triisopropanolamine; and basic amino acids such as L-arginine. Examples of inorganic bases include sodium hydroxide, potassium hydroxide, and magnesium hydroxide. These basic substances may be added in an amount sufficient to neutralize the second water-soluble polymer, and the addition amount of the basic substance may be, for example, 20% by mass or more and 90% by mass or less based on the second water-soluble polymer.

[0049] In addition to components (A) and (B), the oil-in-water type emulsion composition may further contain other water-soluble polymers other than components (A) and (B). Examples of other water-soluble polymers include xanthan gum, cellulose gum, agar, gellan gum, methyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, collagen, hyaluronic acid, carrageenan, and the like. The oil-in-water type emulsion composition may contain one other water-soluble polymer alone or a combination of two or more thereof. When the oil-in-water type emulsion composition contains other water-soluble polymers, the content thereof may be, for example, greater than 0% by mass and 10% by mass or less, preferably 5% by mass or less, 1% by mass or less, or 0.5% by mass or less, and preferably 0.01% by mass or more, based on the oil-in-water type emulsion composition.

[0050] The content of component (B) in the oil-in-water type emulsion composition may be, for example, 0.0001% by mass or more and 10% by mass or less, based on the oil-in-water type emulsion composition. The content of component (B) may preferably be 0.001% by mass or more, 0.005% by mass or more, 0.01% by mass or more, 0.02% by mass or more, 0.05% by mass or more, or 0.08% by mass or more. Also, the content of component (B) may preferably be 2% by mass or less, 1% by mass or less, 0.6% by mass or less, 0.4% by mass or less, or 0.2% by mass or less. When the content of component (B) is within the above range, an appropriate elastic feeling is generated by the interaction with component (A), and there is a tendency that the freshness can be further improved.

[0051] The mass-based content ratio (A) / (B) of component (A) to component (B) in the oil-in-water type emulsion composition may be, for example, 0.01 or more and 1000 or less. The content ratio of component (A) to component (B) may preferably be 0.05 or more, 0.1 or more, 0.5 or more, 1 or more, 2 or more, 4 or more, 6 or more, or 8 or more, and may preferably be 500 or less, 200 or less, 100 or less, 50 or less, 30 or less, 15 or less, or 12 or less. When the mass content ratio of component (A) to component (B) is at least the above lower limit value, stickiness tends to be more reduced. Also, when it is at most the above upper limit value, a more appropriate elastic feeling is obtained and moistness tends to be more improved.

[0052] Component (C) The oil-in-water type emulsion composition contains, as component (C), a powder having polyglyceryl polyisostearate disposed on the surface. The oil-in-water type emulsion composition may contain component (C) alone or in combination of two or more. The powder having polyglyceryl polyisostearate disposed on the surface can be obtained, for example, by surface-treating the powder with polyglyceryl polyisostearate. By including in combination a powder having a specific compound disposed on the surface with component (A), when the oil-in-water type emulsion composition is applied to the skin, the adhesion to the skin tends to be improved. This can be considered, for example, because due to the interaction between component (A) and the specific compound of component (C), the dispersibility and adhesiveness of component (C) are further improved.

[0053] The powder to be subjected to surface treatment (hereinafter also referred to as untreated powder) is not particularly limited by the shape such as plate-like, spindle-like, needle-like; the particle diameter such as smoky, fine particles, pigment grade; the particle structure such as porous, non-porous, etc. Examples of the powder include inorganic powders, lustrous powders, organic powders, colored pigments, composite powders, polyethylene terephthalate·aluminum·epoxy laminate powder, polyethylene terephthalate·polymethyl methacrylate laminate powder, and the like.

[0061] The polyglyceryl polyisostearate used for surface treatment of the powder is composed of an ester bond between isostearic acid and polyglycerol. Since isostearic acid has a branched-chain structure, the polyglyceryl polyisostearate is considered to have an excellent effect of improving the dispersibility of the surface-treated powder.

[0062] The isostearic acid that constitutes polyglyceryl polyisostearate may be one kind or a mixture of two or more kinds of branched stearic acids. For example, 5,7,7-trimethyl-2-(1,3,3-trimethylbutyl)-octanoic acid can be produced by subjecting isobutylene dimer to an oxo reaction to obtain a branched aldehyde with 9 carbon atoms, then subjecting this aldehyde to aldol condensation to obtain a branched unsaturated aldehyde with 18 carbon atoms, and then hydrogenating and oxidizing it (hereinafter abbreviated as "aldol condensation type"), which is commercially available from, for example, Nissan Chemical Industries, Ltd. 2-Heptylundecanoic acid can be produced by subjecting nonyl alcohol to a Guerbet reaction and then oxidizing it, which is commercially available from, for example, Mitsubishi Chemical Corporation, and as a similar mixture with slightly different branching positions, it is commercially available from Nissan Chemical Industries, Ltd., and furthermore, a type with two methyl branches where the starting alcohol is not straight-chain saturated is also commercially available from Nissan Chemical Industries, Ltd. (hereinafter generally abbreviated as "Guerbet reaction type"). Also, methyl-branched isostearic acid can be obtained, for example, as a by-product during the production of dimer of oleic acid [as described in, for example, J.Amer.Oil Chem.Soc., 51, 522 (1974)], and examples include those commercially available from Emery, Inc. in the United States (hereinafter abbreviated as "Emery type"). The starting material of the dimer acid, which is the starting material of Emery type isostearic acid, may contain not only oleic acid but also linoleic acid, linolenic acid, etc.

[0063] The number of isostearic acid partial structures contained in polyglyceryl polyisostearate may be, for example, 1 or more and 10 or less, preferably 2 or more, or 3 or more, and preferably 6 or less, or 4 or less.

[0064] Polyglycerin is formed by the condensation of glycerin. The number of glycerin structural units contained in polyglycerin may be, for example, 1 to 10, preferably 1 to 6, 2 to 4, or 2.

[0065] Specific examples of polyglyceryl polyisostearate include glyceryl diisostearate, glyceryl triisostearate, diglyceryl isostearate (polyglyceryl-2 isostearate), diglyceryl diisostearate (polyglyceryl-2 diisostearate), diglyceryl triisostearate (polyglyceryl-2 triisostearate), diglyceryl tetraisostearate (polyglyceryl-2 tetraisostearate), decaglyceryl decaisostearate (polyglyceryl-10 decaisostearate), and the like. Preferably, polyglyceryl polyisostearate may contain at least one of polyglyceryl-2 triisostearate and polyglyceryl-2 tetraisostearate. By containing polyglyceryl-2 triisostearate or polyglyceryl-2 tetraisostearate, the interaction with component (A) tends to be further improved.

[0066] Examples of polyglyceryl-2 isostearate include Cosmol (registered trademark) 41V (manufactured by Nisshin Oillio Group). Examples of polyglyceryl-2 diisostearate include Cosmol (registered trademark) 42V (manufactured by Nisshin Oillio Group). Examples of polyglyceryl-2 triisostearate include Cosmol (registered trademark) 43V (manufactured by Nisshin Oillio Group). Examples of polyglyceryl-2 tetraisostearate include Cosmol (registered trademark) 44V (manufactured by Nisshin Oillio Group). Examples of commercially available products of powder surface-treated with polyglyceryl polyisostearate include PGQ TiO2 R250 (manufactured by Daito Kasei Kogyo Co., Ltd.), PGQ RED No.211P (manufactured by Daito Kasei Kogyo Co., Ltd.), and the like.

[0067] The amount of polyglyceryl polyisostearate used in the surface treatment of the powder may be, for example, 0.1% by mass or more and 30% by mass or less, preferably 0.5% by mass or more, or 1% by mass or more, and preferably 10% by mass or less, 5% by mass or less, or 3% by mass or less, based on the untreated powder.

[0068] The average particle size of the surface-treated powder may be, for example, 0.01 μm or more and 100 μm or less, preferably 0.01 μm or more and 50 μm or less. In this specification, the average particle size is measured using a desktop scanning electron microscope (proX PREMIUM, manufactured by Thermo Fisher Scientific) at an acceleration voltage of 5 kV to 15 kV and a magnification of 1000 times to 25000 times, and is calculated from the equivalent spherical diameter measured for 50 particles in an arbitrary field of view of the obtained image data.

[0069] As the method of surface treatment, a conventionally known method can be used. For example, polyglyceryl polyisostearate, which is a surface treatment agent, and powder particles to be treated are added to a solvent, stirred using a ball mill or the like, dried if necessary, washed with water and filtered repeatedly, and after removing impurities, dried and pulverized to obtain a powder surface-treated with the target polyglyceryl polyisostearate.

[0070] The oil-in-water type emulsion composition may contain a powder surface-treated with a surface treatment agent other than polyglyceryl polyisostearate in addition to the component (C). The oil-in-water type emulsion composition may contain a powder surface-treated with another surface treatment agent alone or in combination of two or more. Examples of other surface treatments other than polyglyceryl polyisostearate include fluorine compound treatment, silica treatment, alumina treatment, aluminum hydroxide treatment, silicone treatment, silicone resin treatment, pendant treatment, silane coupling agent treatment, titanium coupling agent treatment, silane treatment, oil agent treatment, N-acylated lysine treatment, polyacrylic acid treatment, metal soap treatment, acrylic resin treatment, metal oxide treatment, and the like. These surface treatments may be used alone or in combination of two or more. When the oil-in-water type emulsion composition contains a powder surface-treated with another treatment, the content thereof may be, for example, more than 0% by mass and 20% by mass or less, preferably 15% by mass or less, 12% by mass or less, 8% by mass or less, 1% by mass or less, or 0.1% by mass or less, based on the oil-in-water type emulsion composition. The content of the powder surface-treated with another treatment may be 1% by mass or more, 2% by mass or more, or 5% by mass or more.

[0071] The content rate of component (C) in the oil-in-water type emulsion composition may be, for example, 0.5 mass% or more and 50 mass% or less with respect to the oil-in-water type emulsion composition. The content rate of component (C) may preferably be 1 mass% or more, 2 mass% or more, 4 mass% or more, 6 mass% or more, 10 mass% or more, or 20 mass% or more, and may be 40 mass% or less, or 30 mass% or less. When the content rate of component (C) is within the above range, good dispersibility can be exhibited with respect to the moderately loose network structure formed by component (A) and component (B), and there is a tendency for a good sense of elasticity.

[0072] The content ratio (A) / (C) on a mass basis of component (A) to component (C) in the oil-in-water type emulsion composition may be, for example, 0.001 or more and 1 or less. The content ratio of component (A) to component (C) may preferably be 0.005 or more, 0.008 or more, 0.01 or more, 0.02 or more, or 0.03 or more, and may preferably be 0.6 or less, 0.3 or less, 0.2 or less, 0.1 or less, 0.08 or less, or 0.06 or less. When the content ratio of component (A) to component (C) is within the above range, there is a tendency for a more favorable bouncy sense of elasticity.

[0073] The content ratio (B) / (C) on a mass basis of component (B) to component (C) in the oil-in-water type emulsion composition may be, for example, 0.0001 or more and 0.1 or less. The content ratio of component (B) to component (C) may preferably be 0.0005 or more, 0.0008 or more, 0.001 or more, 0.002 or more, or 0.003 or more, and may preferably be 0.06 or less, 0.03 or less, 0.02 or less, 0.01 or less, 0.008 or less, or 0.006 or less. When the content ratio of component (B) to component (C) is within the above range, there is a tendency for the unique freshness of the gel to be better.

[0074] In the oil-in-water type emulsion composition, the content ratio ((A) + (B)) / (C) based on mass of the total of component (A) and component (B) with respect to component (C) may be, for example, 0.001 or more and 1 or less. The content ratio of component (A) with respect to component (C) may preferably be 0.005 or more, 0.008 or more, 0.01 or more, 0.02 or more, or 0.03 or more, and may preferably be 0.6 or less, 0.3 or less, 0.2 or less, 0.1 or less, 0.08 or less, or 0.06 or less. When the content ratio of the total of component (A) and component (B) with respect to component (C) is within the above range, there is a tendency for a plump elastic feeling and the moistness peculiar to a gel to become better.

[0075] Component (D) The oil-in-water type emulsion composition may further contain at least one surfactant selected from the group consisting of nonionic surfactants and amphoteric surfactants having an HLB value of 14.0 or more as component (D). By containing a specific surfactant as component (D), the oil-in-water type emulsion composition tends to have a more improved elastic feeling and a more improved adhesion to the skin. Furthermore, by more improving the dispersibility of component (C), there is a tendency for the makeup retention to be more improved. The oil-in-water type emulsion composition may contain component (D) alone or in combination of two or more. Also, component (D) may contain two or more nonionic surfactants or amphoteric surfactants, or may contain a combination of at least one nonionic surfactant and at least one amphoteric surfactant.

[0076] The HLB (Hydrophilic-Lypophilic Balance) value in a nonionic surfactant is an index indicating the degree of affinity between water and oil (hydrophobic oil), and the higher the value, the higher the hydrophilicity. The HLB value can be determined as a value unique to each substance or is publicly known. The HLB value indicates the molecular weight of the hydrophilic group part in the total molecular weight of the surfactant and is determined by Griffin's formula.

[0077] Examples of nonionic surfactants with an HLB value of 14.0 or higher include polyoxyethylene hydrogenated castor oil, polyoxyethylene sugar fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene alkyl ether, polyethylene glycol fatty acid ester, polyoxyethylene glycerin fatty acid ester, polyglycerin fatty acid ester, polyoxyethylene cholesteryl ether, polyoxyethylene phytosterol, polyoxyethylene cholestanol, polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene alkyl phenyl ether, etc., and may contain at least one selected from the group consisting of these. Among these nonionic surfactants, polyoxyethylene hydrogenated castor oil, polyoxyethylene sugar fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene alkyl ether, and polyethylene glycol fatty acid ester may contain at least one selected from the group consisting of these because they can better impart elasticity to the oil-in-water type emulsion composition. More preferably, it may contain at least one selected from the group consisting of polyoxyethylene sugar fatty acid ester and polyoxyethylene sorbitan fatty acid ester, and it is even more preferable to contain at least polyoxyethylene sugar fatty acid ester. The polyoxyethylene sugar fatty acid ester preferably contains at least a polyethylene glycol derivative of a fatty acid ester of glucose or alkylglucose, and more preferably contains at least a polyethylene glycol derivative of an alkylglucose fatty acid ester.

[0079] Polyoxyethylene sugar fatty acid esters are polyethylene glycol derivatives of sugar fatty acid esters. The sugar fatty acid ester may be a compound obtained by reacting a saturated or unsaturated fatty acid having 12 to 22 carbon atoms with a saccharide or an alkyl saccharide containing an alkyl group having 1 to 8 carbon atoms. Examples of the saccharide include glucose, sucrose, galactose, fructose, lactose, mannose, maltose, trehalose, melibiose, raffinose, ribose and the like. Among them, the sugar fatty acid ester is preferably a fatty acid ester of glucose or alkyl glucose. The alkyl glucose may be an ether composed of an alkyl group having 1 to 8 carbon atoms, preferably 1 to 4 carbon atoms, and glucose, and may preferably be methyl glucose.

Phospholipids are amphiphilic substances and are classified as amphoteric surfactants in this specification.

[0086] The amphoteric surfactant in component (D) may contain at least phospholipids. Phospholipids are also called lecithin. Phospholipids are surfactant substances with good affinity for the skin and high moisturizing effects. With the surfactant effect of phospholipids, an emulsified composition with excellent usability and moisturizing properties can be obtained.
