Description

Technical Field

[0001] The present invention relates to an aqueous dispersion type emulsion composition, a method for producing the same, an emulsion addition-curing composition obtained by addition-curing the aqueous dispersion type emulsion composition, and a cosmetic containing the emulsion addition-curing composition. Background Art

[0002] Transparent or translucent microemulsions composed of surfactants, aqueous phases, and oil phases are roughly classified into three types: aqueous dispersion type emulsions in which the continuous phase is water, oil dispersion type emulsions in which the continuous phase is oil, and bicontinuous emulsions in which the continuous phase is composed of water and oil. In particular, microemulsion compositions having a bicontinuous structure can provide cosmetics with improved functionality and usability, and examples thereof include cleansing agents or compositions used as skin and hair cleansing agents (Patent Documents 1 to 7).

[0003] Compared with aqueous dispersion type emulsions or oil dispersion type emulsions, bicontinuous microemulsion compositions must use a large amount of surfactants. When used as cosmetics, sticky or greasy feelings caused by the surfactants will remain. Therefore, in order to maintain a light touch, it is necessary to reduce the amount of surfactants used (Patent Document 8). In addition, when silicone oil is used in the oil phase, although the touch can be improved, there are few reported precedents and the types of surfactants are limited.

[0004] By using surfactin, a natural surfactant, a microemulsion composition containing silicone oil can be produced. Patent Document 9 reports an emulsifying composition composed of surfactin, amino-modified silicone, and an aqueous solvent. Although it is characterized by high emulsifying power and a small amount of surfactant, since the surfactant is anionic, compared with nonionic surfactants, a sticky feeling caused by the surfactant remains severely. In addition, the silicone that can be used is limited, and there is no reported example of using an organopolysiloxane having a reactive functional group such as a hydrosilyl group or an ethylenically unsaturated group.

[0005] On the other hand, as a method for reducing the sticky feeling, a method of using silicone particles that can impart a dry feeling, smoothness, and other usability and extensibility is known (Patent Documents 10 and 11). In particular, silicone fine particles obtained by covering silicone rubber spherical particles with polyorganosilsesquioxane have a soft touch and excellent dispersibility, and thus are incorporated into many cosmetics. Its production method passes through an aqueous dispersion type emulsion obtained by a method such as the Agent-in-Oil method represented by the phase inversion emulsification method, but there is no report on an aqueous dispersion type emulsion obtained by the D-phase emulsification method or the liquid crystal emulsification method.

[0020] Technical Problem to be Solved by the Invention

[0021] The present invention has been completed in view of the above circumstances, and an object thereof is to provide a water-dispersible emulsion composition, an emulsion addition-curing composition obtained by addition-curing the same, and a cosmetic containing the emulsion addition-curing composition, wherein the water-dispersible emulsion composition provides a reduced stickiness, good usability, refreshing feeling and stability over time, and in particular, excellent makeup persistence, scratch resistance and soft focus effect.

[0022] Technical Means for Solving the Technical Problem

[0023] In order to achieve the above technical problem, the present invention provides a water-dispersible emulsion composition, which is a water-dispersible emulsion composition containing the following components (A), (B), (C), (D) and (E), and has a milky white appearance at 25°C and spherical emulsion particles with an average particle diameter of 2.0 μm or less:

[0024] (A) An anionic surfactant;

[0025] (B) An organopolysiloxane having at least 2 hydrosilyl groups in one molecule represented by the following formula (I),

[0026] [Chemical formula 1]

[0027]

[0028] R 1 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms and no aliphatic unsaturated bond, R 2 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms and no aliphatic unsaturated bond, and part of R 2 Is optionally a hydrogen atom, a is 0 ≤ a ≤ 300, b is 0 ≤ b ≤ 50 and 5 ≤ a + b ≤ 350. When b = 0, any two or more R 2 Are hydrogen atoms;

[0029] (C) An organopolysiloxane having at least 2 ethylenically unsaturated groups in one molecule represented by the following formula (II),

[0030] [Chemical formula 2]

[0031]

[0032] R 3 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms and no aliphatic unsaturated bond, R 4 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 2 to 30 carbon atoms and having an aliphatic unsaturated bond, or is R 3 , c is 0 ≤ c ≤ 500, d is 0 ≤ d ≤ 50 and 5 ≤ c + d ≤ 550. When d = 0, R 4 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 2 to 30 carbon atoms and having an aliphatic unsaturated bond;

[0033] (D) A monohydric or polyhydric alcohol;

[0034] (E) Water.

[0035] If it is the aqueous dispersion emulsion composition of the present invention, it is prepared via the emulsion composition obtained by emulsifying with phase D, whereby the particle size of the emulsion particles can be simply reduced. In addition, by adding a hydrosilylation catalyst, an emulsion addition-curing composition can be prepared.

[0036] In addition, it is preferable that the aqueous dispersion emulsion composition can be dispersed when the aqueous dispersion emulsion composition is added to water.

[0037] If it is such a water-dispersible emulsion composition, it can be suitably used for applications such as cosmetics.

[0038] In addition, it is preferable that the component (A) is a natural surfactant.

[0039] If it is such a component (A), the environmental load can be reduced, it has high safety, and it can be suitably used for the water-dispersible emulsion composition.

[0040] At this time, it is preferable that the natural surfactant contains a cyclic peptide group represented by the following formula (III).

[0041] [Chemical formula 3]

[0042]

[0043] In the formula, X represents an amino acid residue selected from leucine, isoleucine, and valine; R 5 are each independently a substituted or unsubstituted monovalent hydrocarbon group having 9 to 18 carbon atoms and not having an aliphatic unsaturated bond; L-Leu refers to L-type leucine, D-Leu refers to D-type leucine, and L-Val refers to L-type valine; in addition, the counter ion of the carboxyl group consists of an alkali metal ion.

[0044] Thus, if the natural surfactant is the surfactant represented by the above formula (III), it can be more suitably used for an emulsion composition having an average particle diameter of 2.0 μm or less.

[0045] At this time, it is preferable that X in the formula (III) is leucine and R 5 is a hydrocarbon chain having 12 carbon atoms.

[0046] If the natural surfactant represented by the above formula (III) is such a surfactant, it can be further suitably used for an emulsion composition having an average particle diameter of 2.0 μm or less of emulsion particles.

[0047] In addition, it is preferable that the content of the component (A) in the water-dispersible emulsion composition is 0.1 to 10 wt%.

[0048] If it is such a content of the component (A), an emulsion having an average particle diameter of 2.0 μm or less of emulsion particles will be sufficiently formed.

[0049] In addition, it is preferable that the component (D) is glycerol.

[0050] If it is such a component (D), a D phase (surfactant phase) can be formed in a wide concentration range.

[0051] In addition, it is preferable that the average particle diameter of the emulsion particles is 1.0 μm or less.

[0052] Furthermore, more preferably, the average particle size of the emulsion particles is 500 nm or less.

[0053] If such emulsion particles are used, when used in cosmetics, they are more likely to enter the skin grooves and have better adhesion to the skin.

[0054] In addition, relative to 1 mole of the ethylenically unsaturated group contained in the component (C), the hydrosilyl group contained in the component (B) is preferably 0.5 to 3.0 moles.

[0055] If the hydrosilyl group contained in the above (B) is such a molar amount, when the above emulsion composition is addition-cured, the addition-curing reaction will proceed sufficiently, and a sufficient touch can be obtained.

[0056] In addition, it is preferable that the water-dispersible emulsion composition is addition-cured by adding (F) a hydrosilylation catalyst.

[0057] In this way, by adding the component (F), the above water-dispersible emulsion composition can be addition-cured.

[0058] In addition, the present invention provides a method for preparing a water-dispersible emulsion composition, which includes:

[0059] (1) A step of preparing a mixed solution containing the components (A) to (D);

[0060] (2) A step of adding the component (E) to the mixed solution to obtain a transparent or semi-transparent emulsion composition α; and

[0061] (3) A step of further adding the component (E) to the emulsion composition α to obtain the above water-dispersible emulsion composition.

[0062] If such a manufacturing method is used, a water-dispersible emulsion composition with a smaller particle size can be simply manufactured.

[0063] At this time, it is preferable to form the emulsion composition α into a bicontinuous structure.

[0064] If so, the particle size of the emulsion particles of the obtained water-dispersible emulsion composition becomes finer and more uniform.

[0065] In addition, the present invention provides a method for preparing an emulsion addition-curing composition, which further includes a step of adding (F) a hydrosilylation catalyst in the method for preparing the above water-dispersible emulsion composition.

[0066] If so, an emulsion addition-curing composition suitable for use in cosmetics with reduced greasiness, good usability, refreshing feeling and stability over time, especially excellent makeup durability, scratch resistance and soft focus effect, can be simply manufactured.

[0067] In addition, the present invention provides an addition-curable emulsion composition, which is an addition-curable emulsion composition obtained by addition-curing the above water-dispersed emulsion composition, and has a milky white appearance at 25°C and emulsion particles are spherical particles with an average particle diameter of 2.0 μm or less.

[0068] The stickiness caused by the anionic surfactant in this addition-curable emulsion composition is reduced.

[0069] In addition, it is preferable that the extract obtained when extracting the addition-cured product of the component (B) and the component (C) from the addition-curable emulsion composition is in a solid state.

[0070] If it is such an addition-curable emulsion composition, it can be suitably incorporated into cosmetics as a feel improver.

[0071] At this time, it is preferable that the shape of the solid extract is spherical particles.

[0072] If it is such an addition-curable emulsion composition, it provides cosmetics with more excellent usability.

[0073] In addition, the present invention provides a cosmetic containing the above addition-curable emulsion composition.

[0074] The cosmetic incorporated with the above addition-curable emulsion composition has reduced stickiness caused by anionic surfactants, good usability, refreshing feeling and stability over time, good makeup persistence, good spreading and makeup appearance, and excellent scratch resistance and soft focus effect.

[0075] Advantages of the Invention

[0076] The water-dispersed emulsion composition of the present invention can carry out an addition-curing reaction while maintaining the particle diameter before curing by adding a hydrosilylation catalyst, and an addition-curable emulsion composition can be prepared. The stickiness caused by the anionic surfactant in the cosmetic incorporated with this addition-curable emulsion composition is reduced, and the usability and refreshing feeling are excellent. In particular, since the emulsion is spherical particles, it is easy to enter the gaps of the skin, forming a cosmetic with good adhesion and stability over time, excellent makeup persistence, scratch resistance and soft focus effect. Detailed Embodiments

[0077] As described above, it is required to develop a water-dispersed emulsion composition, an addition-curable emulsion composition obtained by addition-curing the same, and a cosmetic incorporated with this addition-curable emulsion composition, and the water-dispersed emulsion composition provides a cosmetic with reduced stickiness, good usability, refreshing feeling and stability over time, especially excellent makeup persistence, scratch resistance and soft focus effect.

[0078] To achieve the above object, the inventors of the present application conducted in-depth research and found that by using an organopolysiloxane having a reactive functional group such as a hydrosilyl group or an ethylenically unsaturated group represented by the above formulas (I) and (II) as the oil phase, a water-dispersed emulsion composition having a milky white appearance at 25°C and spherical particles with an average particle diameter of the resulting emulsion of 2.0 μm or less can be simply provided.

[0079] Furthermore, it was found that by adding a hydrosilylation catalyst to the above water-dispersed emulsion composition, an emulsion addition-curing composition can be prepared while maintaining the particle diameter before curing. It was further found that a cosmetic containing the resulting emulsion addition-curing composition has reduced stickiness caused by active ingredients, and excellent usability, refreshing feeling, and stability over time, especially excellent makeup durability, scratch resistance, and soft focus effect, thus completing the present invention.

[0080] That is, the present invention is a water-dispersed emulsion composition containing the following components (A), (B), (C), (D), and (E), having a milky white appearance at 25°C and spherical emulsion particles with an average particle diameter of 2.0 μm or less:

[0081] (A) An anionic surfactant;

[0082] (B) An organopolysiloxane having at least 2 hydrosilyl groups in one molecule represented by the following formula (I),

[0083] [Chemical formula 4]

[0084]

[0085] R 1 Each independently is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms and no aliphatic unsaturated bond, R 2 Each independently is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms and no aliphatic unsaturated bond, and part of R 2 Is optionally a hydrogen atom, a is 0 ≤ a ≤ 300, b is 0 ≤ b ≤ 50, and 5 ≤ a + b ≤ 350. When b = 0, any two or more R 2 Are hydrogen atoms;

[0086] (C) An organopolysiloxane having at least 2 ethylenically unsaturated groups in one molecule represented by the following formula (II),

[0087] [Chemical formula 5]

[0088]

[0089] R 3Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms and no aliphatic unsaturated bond, R 4 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 2 to 30 carbon atoms and having an aliphatic unsaturated bond, or is R 3 , c is 0 ≤ c ≤ 500, d is 0 ≤ d ≤ 50 and 5 ≤ c + d ≤ 550. When d = 0, R 4 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 2 to 30 carbon atoms and having an aliphatic unsaturated bond;

[0090] (D) Monohydric or polyhydric alcohols;

[0091] (E) Water.

[0092] Hereinafter, the present invention will be described in detail, but the present invention is not limited thereto.

[0093] [Component (A)]

[0094] The (A) anionic surfactant used in the present invention has an anionic hydrophilic group in its molecular structure, and the hydrophobic group is formed by a straight-chain or branched hydrocarbon chain, an aromatic ring or a heterocyclic ring, and a structure formed by combining them. For example, fatty acid soaps such as sodium stearate and triethanolamine palmitate, alkyl ether carboxylic acids and their salts, condensate salts of amino acids and fatty acids, alkane sulfonates, alkene sulfonates, sulfonates of fatty acid esters, sulfonates of fatty acid amides, sulfonates of formalin condensation type, alkyl sulfate esters, higher secondary alcohol sulfate esters, alkyl and allyl ether sulfate esters, sulfate esters of fatty acid esters, sulfate esters of fatty acid alkanolamides, sulfate ester salts such as Turkey red oil, alkyl phosphates, ether phosphates, alkyl allyl ether phosphates, amide phosphates, N-acyl lactates, N-acyl sarcosinates, N-acyl amino acid surfactants, natural surfactants represented by lecithin, bile acid, and surfactin, etc. These anionic surfactants can be used alone or in combination of two or more. Natural surfactants are particularly preferably used.

[0095] Natural surfactants refer to surfactants from biological components with relatively high safety that reduce the environmental load. Compared with general synthetic surfactants, they are large in volume and have multifunctionality. In these aspects, their chemical structure is specific, and they do not contain components from petroleum. Therefore, they have characteristics such as special functionality, biodegradability, low toxicity, and biological activity, and have attracted much attention in recent years. Specifically, lecithin, bile acid, surfactin, etc. can be cited. Among these natural surfactants, surfactin is particularly preferably used.

[0096] Surfactin is a natural surfactant containing a cyclic peptide group represented by the following formula (III). Surfactin is a biosurfactant produced by Bacillus subtilis, which has a hydrophilic part with a cyclic peptide structure composed of 7 amino acids and a hydrophobic part formed by a hydrocarbon group. Surfactin is a general term for compounds with different alkyl chain lengths and degrees of branching of the hydrocarbon group. Compared with other anionic surfactants, sodium subtilisin, which is a sodium salt, has lower skin irritation. In addition, the cyclic peptide structures attract each other through hydrogen bonds between molecules, and thus have the property of showing a very low value of 0.0003 wt% for the critical micelle concentration.

[0097] [Chemical formula 6]

[0098]

[0099] In the formula, X represents an amino acid residue selected from leucine, isoleucine, and valine. R 5 are each independently a substituted or unsubstituted monovalent hydrocarbon group having 9 to 18 carbon atoms and no aliphatic unsaturated bond. L-Leu refers to L-leucine, D-Leu refers to D-leucine, and L-Val refers to L-valine. In addition, the counterions of the carboxyl group are composed of alkali metal ions.

[0100] X is an amino acid residue selected from leucine, isoleucine, and valine. Leucine is preferred.

[0101] R 5 are each independently a substituted or unsubstituted monovalent hydrocarbon group having 9 to 18 carbon atoms and no aliphatic unsaturated bond. For example, R 5 is an alkyl group, aryl group, or aralkyl group having 9 to 18 carbon atoms. More specifically, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, etc. can be mentioned. Nonyl, decyl, undecyl, and dodecyl having 9 to 12 carbon atoms are particularly preferred.

[0102] In the natural surfactant containing a cyclic peptide group (surfactin) represented by the above formula (III), it is preferred that the amino acid residue is leucine, R 5 is a hydrocarbon chain having 12 carbon atoms with a branched chain, and more preferably the counterion of the carboxyl group is sodium ion. As an example, the natural surfactant described in Patent Document 12 can be used. As such a substance, for example, "KANEKA Surfactin" manufactured by KANEKA CORPORATION can be used, but it is not limited to this example.

[0103] [Component (B)]

[0104] The organopolysiloxane having at least 2 hydrosilyl groups in one molecule of (B) used in the present invention is represented by the following formula (I).

[0105] [Chemical Formula 7]

[0106]

[0107] R 1 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms and no aliphatic unsaturated bond. R 2 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms and no aliphatic unsaturated bond. Some of the R 2 Optionally represents a hydrogen atom. a is 0 ≤ a ≤ 300, b is 0 ≤ b ≤ 50, and 5 ≤ a + b ≤ 350. When b = 0, any two or more of the R 2 are hydrogen atoms. When b = 1, any one or more of the R 2 are hydrogen atoms.

[0108] In the above formula (I), R 1 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms, preferably 1 to 10 carbon atoms, and no aliphatic unsaturated bond. For example, R 1 is an alkyl group, aryl group, aralkyl group having 1 to 30 carbon atoms, or a group in which a hydrogen atom bonded to a carbon atom of these groups is substituted with a halogen atom, amino group, or carboxyl group. Among them, an alkyl group, aryl group, aralkyl group, fluorine-substituted alkyl group, chlorine-substituted alkyl group, amino-substituted alkyl group, carboxyl-substituted alkyl group having 1 to 10 carbon atoms are preferred. More specifically, methyl, ethyl, propyl, butyl, pentyl, cyclopentyl, cyclohexyl, phenyl, tolyl, trifluoropropyl, heptadecafluorodecyl, chloropropyl, chlorophenyl, etc. can be mentioned. An alkyl group, phenyl, or trifluoropropyl having 1 to 5 carbon atoms is particularly preferred.

[0109] In the above formula (I), R 2 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms, preferably 1 to 10 carbon atoms, and no aliphatic unsaturated bond, or a hydrogen atom. Examples of the hydrocarbon group are an alkyl group, aryl group, aralkyl group having 1 to 30 carbon atoms, or a group in which a hydrogen atom bonded to a carbon atom of these groups is substituted with a halogen atom, amino group, or carboxyl group. Among them, an alkyl group, aryl group, aralkyl group, fluorine-substituted alkyl group, chlorine-substituted alkyl group, amino-substituted alkyl group, carboxyl-substituted alkyl group having 1 to 10 carbon atoms are preferred. More specifically, methyl, ethyl, propyl, butyl, pentyl, cyclopentyl, cyclohexyl, phenyl, tolyl, trifluoropropyl, heptadecafluorodecyl, chloropropyl, chlorophenyl, etc. can be mentioned. An alkyl group, phenyl, or trifluoropropyl having 1 to 5 carbon atoms, and a hydrogen atom are particularly preferred.

[0110] In the above formula (I), a satisfies 0 ≤ a ≤ 300, preferably 10 ≤ a ≤ 100. If a is greater than 300, the molecular structure becomes larger, so the stability after emulsification becomes poor. b satisfies 0 ≤ b ≤ 50, preferably 0 ≤ b ≤ 30. If b is greater than 50, the number of crosslinking points during the addition reaction increases, so the resulting cured product becomes hard and the touch is impaired. a + b satisfies 5 ≤ a + b ≤ 350, preferably 10 ≤ a + b ≤ 150. If a + b is less than 5, the molecular weight of the cured product after the addition reaction becomes smaller, so the properties of the resulting cured product are close to liquid state and the touch is impaired. If a + b is greater than 350, the molecular structure becomes larger, so the stability after emulsification becomes poor.

[0111] [Component (C)]

[0112] The organopolysiloxane having at least 2 ethylenically unsaturated groups in one molecule of (C) used in the present invention is represented by the following formula (II).

[0113] [Chemical formula 8]

[0114]

[0115] R 3 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms and no aliphatic unsaturated bond, R 4 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 2 to 30 carbon atoms and having an aliphatic unsaturated bond, or is R 3 , c satisfies 0 ≤ c ≤ 500, d satisfies 0 ≤ d ≤ 50 and 5 ≤ c + d ≤ 550. When d = 0, R 4 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 2 to 30 carbon atoms and having an aliphatic unsaturated bond.

[0116] In the above formula (II), R 3 Each independently represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms, preferably 1 to 10 carbon atoms, and no aliphatic unsaturated bond. For example, R 3 is an alkyl group, an aryl group, an aralkyl group having 1 to 30 carbon atoms, or a group in which a hydrogen atom bonded to a carbon atom of these groups is substituted with a halogen atom, an amino group or a carboxyl group. Among them, an alkyl group, an aryl group, an aralkyl group, a fluorine-substituted alkyl group, a chlorine-substituted alkyl group, an amino-substituted alkyl group, and a carboxyl-substituted alkyl group having 1 to 10 carbon atoms are preferred. More specifically, methyl, ethyl, propyl, butyl, pentyl, cyclopentyl, cyclohexyl, phenyl, tolyl, trifluoropropyl, heptadecafluorodecyl, chloropropyl, chlorophenyl, etc. can be mentioned. An alkyl group, phenyl or trifluoropropyl having 1 to 5 carbon atoms is particularly preferred.

[0117] In addition, in the above formula (II), R 4Each of them is independently a substituted or unsubstituted monovalent hydrocarbon group having 2 to 30 carbon atoms, preferably 2 to 10 carbon atoms, and having an aliphatic unsaturated bond, or a 3 The hydrocarbon group having an aliphatic unsaturated bond includes, for example, vinyl, allyl, propenyl, hexenyl, styryl, etc. Vinyl is particularly preferred. 4 With R 3 Same as above.

[0118] In the above formula (II), c is 0≤c≤500, and d is 0≤d≤50. c is 0≤c≤500, preferably 10≤c≤400. If c is greater than 500, the molecular structure becomes larger, and thus the stability after emulsification deteriorates. d is 0≤d≤50, preferably 0≤d≤30, and further preferably 0≤d≤10. If d is greater than 50, the number of cross-linking points during the addition reaction increases, and thus the resulting cured product becomes harder, resulting in a damaged touch. c+d is 5≤c+d≤550, preferably 10≤c+d≤400. If c+d is less than 5, the molecular weight of the cured product after the addition reaction decreases, and thus the properties of the resulting cured product are close to liquid and the touch is damaged. If c+d is greater than 550, the molecular structure becomes larger, and thus the stability after emulsification deteriorates.

[0119] [(D) ingredient]

[0120] The monohydric or polyhydric alcohol (D) used in the present invention is a commonly used monohydric alcohol or polyhydric alcohol. Specific examples of such monohydric or polyhydric alcohols include lower or higher primary alcohols, sugar alcohols such as erythritol, maltitol, xylitol, and sorbitol, and polyols such as 1,3-BG, glycerol, PG, and DPG. These can be used alone or in appropriate combinations of two or more. Water-soluble polyols are particularly preferably used.

[0121] The polyol is preferably a 1,2-alkanediol having 5 to 10 carbon atoms or other polyols, one or a combination of two or more thereof. By combining the polyol with the anionic surfactant (A), the HLB (Hydrophilic-Liphilic Balance) can be adjusted, making it easier to form the D phase.

[0122] Specific examples of 1,2-alkanediols having 5 to 10 carbon atoms include 1,2-pentanediol, 1,2-hexanediol, 1,2-heptanediol, 1,2-octanediol, 1,2-nonanediol, and 1,2-decanediol. Among these, one or more of 1,2-hexanediol, 1,2-heptanediol, and 1,2-octanediol are preferably used.

[0123] As polyols having 5 to 10 carbon atoms other than 1,2-alkanediol, as long as they are used as cosmetic raw materials, there is no particular limitation. For example, ethylene glycol, diethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, polypropylene glycol, glycerin, diglycerin, polyglycerin, 1,3-butanediol, isopentylene glycol, sorbitol, mannitol, glycol, etc. can be exemplified. Dipropylene glycol, glycerin, and 1,3-butanediol are particularly preferred. When glycerin is further used, since the D phase can be formed in a wide concentration range, it is particularly preferred.

[0124] In cosmetics, it is preferred that the total blending amount of the (D) monohydric or polyhydric alcohol is 1.0 to 70% by mass, and more preferably 5 to 50% by mass. If the blending amount is 1.0% by mass or more, the D phase is likely to be formed.

[0125] [Water-dispersible emulsion composition and method for preparing the same]

[0126] The present invention is a water-dispersible emulsion composition containing the above components (A) to (E). Its appearance at 25 °C is milky white, and the emulsion particles are spherical particles with an average particle diameter of 2.0 μm or less.

[0127] When emulsifying, a general emulsifying and dispersing machine can be used. As examples thereof, high-speed rotary centrifugal radiation type stirrers such as a homogenizing disperser, high-speed rotary shear type stirrers such as a homogenizing mixer, high-pressure jet type emulsifying and dispersing machines such as a homogenizer, a colloid mill, an ultrasonic emulsifier, etc. can be cited.

[0128] When mixing the five components (A) to (E), phase inversion temperature emulsification method, D phase emulsification method, etc. (emulsification step) can be used.

[0129] The phase inversion temperature emulsification method refers to a method of generating a fine emulsion by stirring near the phase inversion temperature (PIT) of HLB balance and then rapidly cooling. Since the interfacial tension between oil and water significantly decreases near the PIT, it is easy to generate fine emulsified particles.

[0130] The D phase emulsification method refers to a method of adjusting the HLB of a surfactant by adding a water-soluble polyhydric alcohol to the surfactant, adding oil after forming the D phase to obtain an O / D emulsion, and then adding water to generate a fine emulsion.

[0131] It is known that the smaller the average particle diameter of the emulsion particles, the more favorable the soft focus effect on cosmetics. In order to produce spherical particles with a small particle diameter by the phase inversion temperature emulsification method, it is necessary to increase the amount of the active ingredient or enhance the shear force during mechanical emulsification, but this will result in greasiness and energy loss. For the above reasons, the D phase emulsification method, which can produce an emulsion formed by small particle diameter spherical particles with low energy and a small amount of the active ingredient, is more preferred.

[0132] Therefore, the present invention provides a method for preparing a water-dispersible emulsion composition, which comprises:

[0133] (1) A step of preparing a mixed solution containing the components (A) to (D);

[0134] (2) A step of adding the component (E) to the mixed solution to obtain a transparent or translucent emulsion composition α; and

[0135] (3) A step of further adding the component (E) to the emulsion composition α to obtain the above-mentioned water-dispersible emulsion composition.

[0136] When performing the D-phase emulsification method, specifically, under the condition of applying shear by a homogenizer, the component (B) and the organopolysiloxane of the component (C) are slowly blended into a mixture of the anionic surfactant of the component (A) and the polyol of the component (D), thereby forming a D-phase (that is, preparing a mixed solution containing the components (A) to (D) (the above step (1))). Then, a specified amount of (E) water is slowly added, thereby obtaining an emulsion composition α (hereinafter, also referred to as a microemulsion composition α) (the above step (2)).

[0137] The appearance of the emulsion composition α is transparent or translucent, and the average particle diameter or structural period of its microemulsion is 200 nm or less. At the stage of adding (E) water to the white D-phase gel formed by (A) to (D), through the transparent or translucent microemulsion composition α, and by further adding (E) water, it finally phase-transfers into a milky white water-dispersible emulsion (the above step (3)). By adding an appropriate amount of (E) water, the transparent or translucent microemulsion turns milky white, which indicates a high possibility of obtaining a water-dispersible emulsion.

[0138] The appearance of the water-dispersible emulsion composition of the present invention is milky white, and its emulsion particles are spherical particles with an average particle diameter of 2.0 μm or less. In addition, even if (E) water is further added, it is obtained while maintaining its particle diameter.

[0139] When further adding (E) water to the obtained milky white water-dispersible emulsion composition, (E) water can be added to the water-dispersible emulsion composition, or the water-dispersible emulsion composition can be added to (E) water. The possibility that the average particle diameter of the emulsion composition is greater than 2.0 μm due to changing its addition order is low. In addition, the particle diameter does not change significantly due to the amount of this (E) water.

[0140] In addition, in the method for preparing the water-dispersible emulsion composition of the present invention, it is preferable to form the emulsion composition α into a bicontinuous structure.

[0141] Microemulsions have three types: a micellar aqueous solution phase in which oil is dissolved in water, an inverse micellar oil solution phase in which water is dissolved in oil, and a bicontinuous phase in which both water and oil have a continuous structure. The microemulsion corresponds to any one of these phases.

[0142] It is possible to confirm whether the microemulsion composition α is aqueous or oily by the following method. When several drops of the microemulsion composition α are added dropwise to an excess of water, it disperses quickly and uniformly, while when it is added dropwise to an excess of oil, it does not disperse, then it is aqueous; on the contrary, when it is added dropwise to an excess of oil, it disperses quickly and uniformly, while when it is added dropwise to an excess of water, it does not disperse, then it is oily. The micellar aqueous solution in which oil is dissolved in water is aqueous because it disperses quickly when added to water and does not disperse when added to oil. The inverse micellar oil solution phase in which water is dissolved in oil is oily because it does not disperse when added to water and disperses quickly when added to oil. The bicontinuous phase in which both water and oil have a continuous structure can be either aqueous or oily. Preferably, the microemulsion composition α used in the present invention disperses when added to water, more preferably a micellar aqueous solution or a bicontinuous phase in which oil is dissolved in water, and particularly preferably a bicontinuous phase.

[0143] Furthermore, it is possible to confirm whether the microemulsion composition α is a micellar aqueous solution phase or a bicontinuous phase by the following method. The fact that it has a bicontinuous structure can be confirmed by electron microscope image observation based on the well-known freeze-fracture replica method. It can be more simply confirmed by a pigment dispersion test. The pigment dispersion test is a method of confirming amphiphilicity by adding an aqueous pigment and an oil-soluble pigment respectively and mixing quickly with both water and oil.

[0144] When the microemulsion composition α has a bicontinuous structure that can be dispersed in water, the emulsion particles of the water-dispersed emulsion composition obtained by mixing with water are characterized by being fine and uniform in particle size. Therefore, when preparing the water-dispersed emulsion composition of the present invention via such a microemulsion composition α, the average particle size of its emulsion particles is 2.0 μm or less, and its particle size distribution is very narrow.

[0145] In addition, the water-dispersed emulsion composition of the present invention is characterized in that it is spherical particles with an average emulsion particle size of 2.0 μm or less, preferably with a particle size of 1.0 μm or less, and more preferably with a particle size of 500 nm or less. If the particle size is greater than 2.0 μm, it may be difficult to enter the skin grooves when used in cosmetics, and the adhesion to the skin will deteriorate. The lower limit of the average emulsion particle size is not particularly limited, but it is preferably greater than 200 nm, and more preferably greater than 300 nm. If it is within the above range, the spherical particles entering the skin grooves are likely to fall off during washing, so it is preferred.

[0146] When performing D-phase emulsification using ordinary polyglycerol fatty acid esters or polyoxyethylene glycerol fatty acid esters, the average particle diameter of the emulsion particles in the prepared emulsion composition tends to decrease to about several tens to several hundreds of nm. On the other hand, when performing D-phase emulsification using the (A) anionic surfactant of the present invention, since the steric volume of the structure of anionic surfactants such as surfactin is large, the particle diameter of the emulsion particles of the water-dispersible emulsion composition of the present invention is larger than that of the above-mentioned emulsion particles.

[0147] In addition, it is preferable that the water-dispersible emulsion composition of the present invention can be dispersed when added to water. The water-dispersible emulsion composition of the present invention is preferably aqueous, and as described above, the judgment of whether it is aqueous or oily, and the judgment of whether it is a micellar aqueous solution phase or a bicontinuous phase can be carried out by the same method as the microemulsion composition α.

[0148] In the above emulsification step, the average particle diameter depends on the composition ratio of (A) to (D). For example, by relatively increasing the amount of (A), or relatively decreasing the amounts of (B) and (C), the average particle diameter of the emulsion composition becomes smaller. In addition, by relatively decreasing the amount of (A), or relatively increasing the amounts of (B) and (C), the average particle diameter of the emulsion composition becomes larger, but the emulsification stability decreases. For the above reasons, the upper limit of the emulsion particle diameter for obtaining an emulsion composition with good stability in the present invention is about 2.0 μm. In addition, although the dilution concentration can be changed by the amount of (E) water, the possibility of affecting the particle diameter is low. In addition, in the present invention, the average particle diameter of the emulsion particles is the value of the median particle diameter measured by a laser diffraction / scattering particle size distribution measuring device LA-960 (manufactured by HORIBA, Ltd.).

[0149] In the water-dispersible emulsion composition of the present invention, it is preferable to contain 0.1 to 10% by mass, and more preferably 0.1 to 5% by mass of the (A) anionic surfactant. Since the emulsifying performance of the above surfactant is excellent, an emulsion with a fine particle diameter can be formed with a small amount of addition.

[0150] In the water-dispersible emulsion composition of the present invention, the content ratios of the components (B), (C), (D), and (E) are not particularly limited, but it is preferable that the organopolysiloxane of the component (B) is 10 to 500 parts by mass, the organopolysiloxane of the component (C) is 10 to 1000 parts by mass, the monohydric or polyhydric alcohol of the component (D) is 10 to 500 parts by mass, and the water of the component (E) is 10 to 1600 parts by mass with respect to 10 parts by mass of the anionic surfactant of the component (A). In the above preparation method (i.e., the D-phase emulsification method), it is particularly preferable to obtain the emulsion composition α at the stage of adding 10 to 800 parts by mass of the water of the component (E).

[0151] [Emulsion addition-curing composition and method for preparing the same]

[0152] In addition, the present invention provides an emulsion addition-curing composition which is obtained by addition-curing the above-mentioned aqueous dispersion emulsion composition, and has a milky white appearance at 25°C and spherical emulsion particles with an average particle diameter of 2.0 μm or less.

[0153] The aqueous dispersion emulsion composition of the present invention is preferably addition-cured by a hydrosilylation reaction by adding (F) a hydrosilylation catalyst. The addition of (F) the hydrosilylation catalyst can be carried out after the above-mentioned emulsification step of the aqueous dispersion emulsion composition.

[0154] In the case of an emulsion addition-curing composition obtained by addition-curing an aqueous dispersion emulsion composition containing the above-mentioned components (B) and (C), the influence of heat generation or structural shrinkage caused by the addition-curing reaction on the phase of the emulsion can be suppressed, and the particle diameter after the reaction can be maintained.

[0155] Relative to 1 mole of the ethylenically unsaturated group contained in component (C), the amount of the hydrosilyl group contained in component (B) is 0.5 to 3.0 moles, preferably 0.5 to 1.5 moles. If the amount of the hydrosilyl group is 0.5 mole or more, the subsequent addition-curing reaction proceeds sufficiently, and a sufficient touch can be obtained. In addition, when the amount of the hydrosilyl group is 3.0 moles or less, a large amount of the hydrosilyl group does not remain and hydrogen gas is not generated over time.

[0156] The hydrosilylation reaction is preferably carried out in the presence of a platinum group metal catalyst such as a platinum catalyst or a rhodium catalyst. As (F) the hydrosilylation catalyst, for example, chloroplatinic acid, alcohol-modified chloroplatinic acid, chloroplatinic acid-vinylsiloxane complex, etc. are preferably used. In addition, in terms of the amount of platinum or rhodium, the usage amount of the catalyst is preferably 50 ppm or less, particularly preferably 20 ppm or less, relative to the total amount of the aqueous dispersion emulsion composition. If the usage amount of such a catalyst is used, coloring of the sample due to excessive inclusion can be suppressed.

[0157] The metal catalysts listed above are hydrophobic, so when directly added to the aqueous dispersion emulsion composition, the curing reaction rate is sometimes slow. Therefore, it is preferable to cover the catalyst with a dispersant such as a nonionic surfactant, thereby increasing the reaction rate.

[0158] The platinum group metal-based catalyst can be added after the emulsification step as described above, or can be dissolved in advance together with the component (B) and the component (C). When adding the platinum group metal-based catalyst after the emulsification step, it can be dissolved in a solvent and added. In addition, when the dispersibility in water is poor, it is preferably added in a state where the platinum group metal-based catalyst is dissolved in a nonionic surfactant (for example, polyoxyethylene lauryl ether, etc.). When the platinum group metal-based catalyst is dissolved in advance together with the component (B) and the component (C), it is preferably cooled to a low temperature of 5°C or lower in advance, so that an addition reaction does not occur before the end of the emulsification step.

[0159] The addition reaction can be carried out at room temperature, for example, 20 to 25°C. The stirring time for the reaction is not particularly limited, but is usually 1 to 24 hours. When the reaction is not completed, it can be carried out under heating at less than 100°C. By carrying out within this temperature range, the structural collapse of the emulsion can be more precisely suppressed.

[0160] [Physical properties of the emulsion addition-curing composition]

[0161] By incorporating the emulsion addition-curing composition of the present invention as a touch modifier into cosmetics, cosmetics with reduced stickiness caused by surfactants, excellent usability, refreshing feeling, and stability over time can be obtained.

[0162] Regarding the emulsion addition-curing composition of the present invention, it is preferable that the extract obtained when extracting the addition-curing product of the component (B) and the component (C) from the emulsion addition-curing composition is solid. The following will be described in detail.

[0163] The addition-curing product of the component (B) and the component (C) contained in the above composition can be in any of a liquid state, a colloidal state, and a solid state. From the perspective of being incorporated into cosmetics as a touch modifier, its property is preferably colloidal or solid, and particularly preferably solid. When the property is solid, from the perspective of usability, the shape is preferably granular. Regarding the confirmation of its property, for example, a method of dropping the emulsion composition into an alcohol typified by ethanol can be cited. At this time, the emulsion is destroyed, and the internal oil phase precipitates, and the property after addition-curing can be confirmed. It is speculated that the principle is that ethanol adsorbs on the water / oil interface, whereby the surfactant detaches and loses its activity ability, and then the emulsion is destroyed. When the component (A) and the component (D) are soluble in ethanol, they can be easily removed by filtration, so the washing operation can be omitted. Or a method of drying to volatilize the water as the outer phase of the emulsion addition-curing composition can be cited. When the component (A) and the component (D) are non-volatile components, since they will remain, they must be washed with a water-soluble solvent thereafter. Regarding the confirmation of the shape, it can be confirmed by a scanning electron microscope (SEM) or a transmission electron microscope (TEM).

[0165] In addition, the present invention provides a cosmetic containing the above emulsion addition-curing composition.

At this time, the blending amount of the above emulsion addition-curing composition is preferably in the range of 0.1 to 40% by mass of the whole cosmetic, and more preferably in the range of 0.1 to 10% by mass. If it is 0.1% by mass or more, a sufficient touch can be obtained, and if it is 40% by mass or less, the usability is good.

[0262] Examples

[0263] Hereinafter, the present invention will be specifically described using examples and comparative examples, but the present invention is not limited thereto.

[0264] (Examples 1 to 25, Preparation Examples 1 to 3)

[0265] According to the compositions shown in Tables 2 to 3, SFNa (KANEKA Surfactin, KANEKA CORPORATION) as the (A) anionic surfactant, the following organopolysiloxanes (1) to (3) of the formula shown as the (B) organopolysiloxane having at least 2 hydrosilyl groups in one molecule, the following organopolysiloxanes (4) to (6) of the formula shown as the (C) organopolysiloxane having at least 2 ethylenically unsaturated groups in one molecule, glycerol as the polyol which is one kind of the (D) monohydric or polyhydric alcohol, decamethylcyclopentasiloxane (KF-995) or linear organopolysiloxane (KF-96A-6cs) (silicone oil having a viscosity of 20 mm 2 / s or less at 25°C and not containing hydrosilyl groups and ethylenically unsaturated groups) as the (H) oil agent other than the components (B) and (C), isododecane as the volatile hydrocarbon oil, and 2-ethylhexyl palmitate as the ester oil were respectively placed in 200 mL glass beakers, stirred and dissolved at room temperature using a disperser, and then (E) water was added dropwise at room temperature to prepare a transparent or translucent microemulsion composition α (Examples 1 to 11, Preparation Examples 1 to 3). Then, further (E) water was added at room temperature to prepare a milky white emulsion composition (Examples 1 to 11). In addition, as shown in Tables 4 and 5, water was further added to the emulsions obtained in Examples 1 to 11 and Preparation Examples 1 to 3 to prepare emulsion compositions (Examples 12 to 25). In Tables 2 to 5, the blending amounts are expressed in mass%. In addition, the dynamic viscosities, vinyl group contents, and hydrosilyl group contents of the organopolysiloxanes (1) to (6) are shown in Table 1.

[0278]

[0279] [Table 1]

[0280]

[0281] Regarding water dispersibility, one drop of the emulsions prepared in Preparation Examples 1 to 3 and Examples 1 to 11 was added to 10 ml of water to investigate the dispersibility (water dispersibility test). Similarly, regarding oil dispersibility, one drop of the emulsion was added to 10 ml of a D5 (decamethylcyclopentasiloxane) solution to investigate the dispersibility (oil dispersibility test). The evaluation of the appearance of the emulsions at 25°C and the results are shown in Tables 2 to 5.

[0282] The obtained emulsions (Preparation Examples 1 to 3, Examples 1 to 25) were subjected to a pigment solubility test. As the test method, regarding water solubility, the solubility was investigated by adding an aqueous solution (concentration 0.1% by mass) of a water-soluble pigment (Blue No. 1) to the obtained emulsion. In addition, regarding oil solubility, in the same manner as above, a solution of an oil-soluble pigment (β-carotene) in decamethylcyclopentasiloxane (concentration 1.0% by mass) was added to the obtained emulsion to investigate the solubility.

[0283] The particle size of the obtained emulsion compositions (Examples 12 to 25) was measured. The values recorded are the median particle size values measured using a laser diffraction / scattering particle size distribution measuring device LA-960 (manufactured by HORIBA, Ltd.).

[0284] [Table 2]

[0285]

[0286] [Table 3]

[0287]

[0288] As shown in Tables 2 to 3 above, microemulsion compositions α with a transparent or translucent appearance at 25°C were obtained in Preparation Examples 1 to 3. Emulsions with a milky white appearance at 25°C were obtained in Examples 1 to 11. When the above emulsions (Preparation Examples 1 to 3, Examples 1 to 11) were dropped into water, they were all uniformly dispersed, so the dispersibility in water was confirmed. On the other hand, when the emulsion was dropped into oil, separation occurred and it was not dispersed in oil. From this, it can be known that the emulsions prepared (Preparation Examples 1 to 3, Examples 1 to 11) have good water dispersibility.

[0289] In the pigment solubility test, since the microemulsion compositions α shown in Preparation Examples 1 to 3, which were transparent or semi-transparent at 25°C, uniformly dissolved both water-soluble pigments and oil-soluble pigments, it was confirmed that they had a bicontinuous structure. On the other hand, the emulsions shown in Examples 1 to 11, which were milky white at 25°C, uniformly dissolved water-soluble pigments but did not dissolve oil-soluble pigments, so it was known that they were water-dispersed emulsions.

[0290] [Table 4]

[0291]

[0292] [Table 5]

[0293]

[0294] As shown in Tables 4 to 5 above, in Examples 16 and 20, no additional water was added. In Examples 12 to 15, 17 to 19, and 21 to 25, they were mixed with the additional water according to the recorded blending compositions. Emulsions with a milky white appearance at 25°C were obtained in all of Examples 12 to 25. In Examples 12 to 14, by adding the additional water, the appearance of the emulsion changed from a transparent or semi-transparent state to a milky white state, so it was considered that there was a phase transition from a bicontinuous structure to a water-dispersed emulsion. In addition, for any of the emulsions, when the emulsion was dropped into water, the result was uniform dispersion, so the dispersibility in water was confirmed. On the other hand, when the emulsion was dropped into oil, the result was separation and it did not disperse in the oil. From this, it was known that the prepared emulsion compositions had good water dispersibility.

[0295] The average particle size of the obtained emulsion compositions was all 2.0 μm or less. From this, it was known that the emulsion particles in the water-dispersed emulsion prepared by this formulation were relatively small.

[0296] (Examples 26 to 30)

[0297] A 200 mL glass beaker containing 100 g of the milky white emulsion compositions of Examples 12, 15-17, and 21 obtained above was maintained at 20-25°C on a stirrer. In this state, a mixture of 0.1 g of a toluene solution of a chloroplatinic acid-vinylsiloxane complex (platinum concentration; 0.5 wt%) (5 ppm of platinum relative to the total amount of the emulsion composition) and 0.1 g of polyoxyethylene lauryl ether (number of ethylene oxide added moles = 9 mol) was added with stirring. The mixture was stirred for 12 hours within the same temperature range as above to allow an addition-curing reaction between the organopolysiloxane having a hydrosilyl group (component B) and the organopolysiloxane having a vinyl group (component C) to proceed, producing emulsion addition-curing compositions (Table 6). NMR analysis revealed the disappearance of all peaks derived from the vinyl group, confirming the progress of the reaction. 100 g of the resulting emulsion addition-cured composition was added to 500 g of ethanol while stirring. The precipitated oily component was isolated by filtration and then dried in an oven at 105°C for 3 hours. If the dried oily component was solid, its shape was confirmed using a scanning electron microscope. Table 6 shows the results of the appearance evaluation at 25°C of the pre-reaction emulsion composition and its addition-cured product, particle size measurement, properties of the precipitated oily component, and the shape of the solid component observed using an electron microscope.

[0298] [Table 6]

[0299]

[0300] As shown in Table 6, in Examples 26 to 30, an emulsion addition curing composition having a milky white appearance at 25°C was obtained. In addition, the particle size measurement confirmed that the particle size change before and after the reaction was small. It is speculated that the curing reaction has little effect on the aggregation or unification of the emulsion particles. Furthermore, regarding the properties of the precipitated oily components, they are colloid in Examples 26 and 30 and solid in Examples 27 to 29. It is speculated based on the combination of raw materials used that when the combination has a low crosslinking density, it is colloid, and when the combination has a high crosslinking density, it is solid. The solid components obtained were observed using an electron microscope, and the results showed that they were all in the shape of spherical particles.

[0301] (Performance Evaluation)

[0302] The emulsion compositions of Examples 12, 15 to 17, 20 and the emulsion addition-curing compositions of Examples 26 to 30 were each dispersed in 95 ml of water to prepare aqueous dispersions of the compositions. Using a dropper, approximately 0.02 g of the prepared aqueous dispersion was dropped onto the back of the hand and spread with a finger to a size of approximately 2 cm in diameter. After air-drying for 3 minutes, it was vigorously wiped with a finger. As a result, although stickiness due to the surfactant was obtained for the aqueous dispersions of the emulsion compositions of Examples 12, 15 to 17, 20, the stickiness of the emulsion addition-curing compositions of Examples 26 to 30 was reduced. In particular, for Examples 27 to 29 having a solid form, a dry feeling in use was confirmed, the spreadability was very good, and the adhesiveness was good. In addition, the soft focus effect was excellent.

[0303] Thus, regarding the aqueous dispersion-type emulsion composition of the present invention, it was confirmed that when an organopolysiloxane having reactive functional groups such as a hydrosilyl group and an ethylenically unsaturated group is used for the oil phase, an aqueous dispersion-type emulsion composition characterized by a milky white appearance and an average particle diameter of the obtained emulsion of 2.0 μm or less can be produced, and an emulsion addition-curing composition can be produced while maintaining the particle diameter by adding a hydrosilylation catalyst to carry out an addition-curing reaction. In addition, it was confirmed that the stickiness caused by the anionic surfactant in the emulsion addition-curing composition of the present invention was reduced. Further, it was confirmed that since the shape is spherical particles, the light diffusibility is excellent and the soft focus effect of naturally hiding the defects of the skin is high.

Then, (E) water was added to the obtained emulsion composition α at room temperature to prepare an emulsion composition (Comparative Examples 3 to 6). In addition, as shown in Table 8, water was further added to the emulsions obtained in Comparative Examples 1 to 6 to prepare emulsion compositions (Comparative Examples 9 to 14). 100 g of the obtained emulsion composition was added to 500 g of ethanol with stirring, and only the precipitated oily component was separated by filtration and dried at 105 °C for 3 hours. In Tables 7 to 8, the blending amounts are expressed in mass %. The results of the evaluation of the appearance of the emulsion at 25 °C, the pigment solubility test, the water dispersibility test, the oil dispersibility test, the particle size measurement, and the properties of the precipitated oily component carried out in the same manner as in the Examples are shown in Tables 7 to 8.

[0311] [Table 7]

[0312]

[0313] As shown in Table 7 above, in Comparative Examples 1 to 2 and 7 to 8, emulsions with a colorless and transparent appearance at 25 °C were obtained. In Comparative Examples 3 to 6, emulsions with a milky white appearance at 25 °C were obtained. Regarding these emulsions, the results of dropping the emulsion into water were all uniformly dispersed, so the dispersibility in water was confirmed. On the other hand, the results of dropping the emulsion into oil were all separation and no dispersion in oil. From this, it can be seen that the prepared emulsion composition has good water dispersibility.

[0314] The emulsions shown in Comparative Examples 1-2 and 7-8, which were colorless and transparent at 25°C, uniformly dissolved both water-soluble pigments and oil-soluble pigments, and thus it was confirmed that they had a bicontinuous structure. On the other hand, the emulsions shown in Comparative Examples 3-6, which were milky white at 25°C, only uniformly dissolved water-soluble pigments, and thus it was known that they were water-dispersed emulsions.

[0315] [Table 8]

[0316]

[0317] As shown in Table 8 above, in Comparative Examples 9-14, they were mixed with water according to the described blending compositions. Emulsions with a milky white appearance at 25°C were obtained in all of Comparative Examples 9-14. In addition, for any of the emulsions, the result of dropping the emulsion into water was uniform dispersion, and thus the dispersibility in water was confirmed. On the other hand, the result of dropping the emulsion into oil was separation and no dispersion in the oil. From this, it was known that the prepared emulsion compositions had good water dispersibility. In addition, the emulsions shown in Comparative Examples 9-14, which were milky white at 25°C, only uniformly dissolved water-soluble pigments, and thus it was known that they were water-dispersed emulsions.

[0318] The average particle size of the obtained emulsion compositions was all 2.0 μm or less. In addition, the properties of the precipitated oily components were all liquid.

[0319] (Performance Evaluation)

[0320] Using a dropper, about 0.02 g of the aqueous dispersions of Comparative Examples 9-14 prepared in the same manner as in Examples 26-30 was dropped onto the back of the hand and spread with a finger to a size of about 2 cm in diameter. After air-drying for 3 minutes, it was vigorously wiped with a finger, and as a result, stickiness caused by the surfactant was obtained.

[0321] (Comparative Examples 15-16)

[0322] A 200 mL glass beaker containing 100 g of the emulsion compositions of Comparative Examples 7 to 8, which were colorless and transparent in appearance as obtained above, was maintained at 20 - 25 °C on a stirring device. In this state, a mixture of 0.1 g of a toluene solution of a chloroplatinic acid - vinylsiloxane complex (platinum concentration; 0.5 wt%) (5 ppm in terms of platinum amount relative to the total amount of the emulsion composition) and 0.1 g of polyoxyethylene lauryl ether (number of moles of ethylene oxide addition = 9 mol) was added with stirring, and stirring was carried out for 12 hours within the same temperature range as above. Thus, an addition curing reaction of the organopolysiloxane having a hydrosilyl group in (B) and the organopolysiloxane having a vinyl group in (C) was carried out to prepare an emulsion addition curing composition (Table 9). It was confirmed by NMR measurement that the peaks from vinyl had disappeared, so it was confirmed that the reaction had proceeded. 100 g of the obtained emulsion addition curing composition was added to 500 g of ethanol with stirring, and only the precipitated oily component was separated by filtration and dried in an oven at 105 °C for 3 hours. When the property of the oily component obtained by drying was in a solid shape, its shape was confirmed using a scanning electron microscope. Table 9 shows the evaluation of the appearance at 25 °C of the emulsion composition before the reaction and its addition cured product, the property of the precipitated oily component, and the results of the shape of the solid component observed by electron microscopy.

[0323] [Table 9]

[0324]

[0325] As shown in Table 9 above, in Comparative Examples 15 to 16, microemulsion addition curing compositions that were colorless and transparent in appearance were obtained according to the described blending compositions. Further, the property of the precipitated oily component was solid. The solid components obtained were observed using an electron microscope, and the results were all in the shape of a bicontinuous structure. This implies that the curing reaction proceeded while maintaining the D - phase state.

[0326] (Performance Evaluation)

[0327] 5 g of the emulsion addition curing compositions of Comparative Examples 15 to 16 were each dispersed in 95 ml of water to prepare aqueous dispersions of the compositions. Using a dropper, approximately 0.02 g of the prepared aqueous dispersion was dropped onto the back of the hand and spread with a finger into a size of approximately 2 cm in diameter. After air - drying for 3 minutes, when wiped vigorously with a finger, compared with Comparative Examples 7 to 8, the stickiness of the aqueous dispersions of the emulsion addition curing compositions of Comparative Examples 15 to 16 was slightly reduced, but compared with Examples 27 to 29, the adhesion of the emulsion addition curing compositions of Comparative Examples 15 to 16 to the skin was low and had a tendency to fall off once wiped. Further, the soft - focus effect of naturally hiding skin defects was weak, and it was considered that the reason was that the shape was not spherical particles, so the light diffusion was low.

[0328] (Examples 31, Comparative Examples 17 - 18)

[0329] [Evaluation of Cosmetic Characteristics]

[0330] Using the emulsion addition-curing composition of Example 27 above and the emulsions of Comparative Examples 4 and 16, cosmetics were prepared in the following manner (Example 31, Comparative Examples 17 - 18). For the feel (greasiness) when applying this cosmetic to the skin, the refreshing feeling (moist feeling), and the stability over time of the prepared cosmetic (state after storage at 50°C for 1 month), evaluation was carried out according to the evaluation criteria shown in Table 10. Based on the average value of the members of the professional panel (10 people), the results were judged according to the following judgment criteria. The results are recorded together in Table 11.

[0331] [Preparation of Cosmetics]

[0332] The component (2) was uniformly mixed into the component (1) in Table 11, thereby obtaining a water-dispersed lotion (cosmetics of Example 31, Comparative Examples 17 - 18).

[0345] In addition, the makeup persistence, scratch resistance, and soft focus effect of the cosmetic of the present invention are particularly excellent.

[0346] In addition, the present invention is not limited to the above-described embodiments.
