Description

Cosmetics

[0001] The present invention relates to a cosmetic containing a crosslinked product.

[0002] By blending organosilicon resins into cosmetics, it is possible to improve the longevity of cosmetics. However, there are two problems to be solved when blending organosilicon resins into cosmetics. The first problem is that the film formed is brittle. Films formed by applying cosmetics containing organosilicon resins to hair, face, hands, etc., crack or peel off with the slightest movement, and therefore lack followability. In particular, the M unit (R 3 SiO 1 / 2 ) and Q units (SiO 4 / 2 MQ resins consisting of (1) and (2) are very rigid and have good mechanical strength, but the coating is brittle, making it difficult to form a free-standing film. On the other hand, MTQ, MDQ, MDTQ, and DT resins, which incorporate T or D units, have improved coating flexibility compared to MQ resins, allowing the formation of strong, free-standing films with conformability. However, the inherent rigidity of the resin remains, leaving issues with abrasion resistance.

[0003] Patent Document 1 discloses that applying an emulsion containing a plasticized MQ resin to a hair cosmetic product enables the formation of a crack-free film. However, when silicone gum is added as a plasticizer, the film strength decreases and the adhesiveness increases, resulting in unpleasant stickiness and a poor feel when used.

[0004] The second issue is oil resistance. When applied to the skin as a cosmetic, oil resistance to sebum is required. The components of sebum are mainly composed of hydrocarbon oils, ester oils, triglycerides, etc. Organosilicon resins used as film-forming agents are highly compatible with these oils. As a result, there is also the issue that after application of the cosmetic, the film swells over time, reducing the physical strength of the cosmetic film and shortening the cosmetic's wear time. Patent Document 2 proposes a highly oil-resistant composition that combines an organosilicon resin and a silicone-modified acrylic polymer. Silicone-modified acrylic polymers form soft films, which can impart some flexibility and conformability, but they do not provide sufficient oil resistance and are not effective in improving cosmetic wear time.

[0005] In recent years, crosslinked organosilicon resins in which organosilicon resins are crosslinked with silicone have been reported. Patent Document 3 reports that a crosslinked organosilicon resin was prepared by heating a vinyl group-containing organosilicon resin and a hydrosilyl group-containing silicone, resulting in a cured product with high flexibility. However, due to its poor solubility in volatile oils, it is difficult to use as a film-forming agent. Patent Documents 4 and 5 also report similar crosslinked organosilicon resins, but they are gel-like and lack film-forming ability. Patent Document 6 reports crosslinking a hydrosilyl group-containing organosilicon resin and a vinyl group-containing silicone by heat curing to prepare a crosslinked organosilicon resin. However, the resulting cured product is sticky and has low solubility in volatile oils. Patent Document 7 reports reacting a hydrosilyl group-containing organosilicon resin with a limited number of reactive sites with a vinyl group-containing silicone to prepare a crosslinked organosilicon resin soluble in volatile oils. However, due to the low reactivity of the hydrosilyl groups, residual platinum catalysts cause the remaining unreacted hydrosilyl groups to react over time, resulting in increased viscosity and hydrogen gas generation, making them difficult to use. Patent Document 8 describes the preparation of an organopolysiloxane gel by crosslinking an organosilicon resin having unsaturated groups with an organohydrogenpolysiloxane having 30 or more D units. However, if the crosslinker chain length is long, the solvent tends to be trapped in the network, resulting in a gel-like state and a sticky film. It also describes the addition of a mercaptopropyl-containing organopolysiloxane as an effective method for terminating post-cure. However, increasing the amount added can cause odor, and there are safety concerns, as this compound has not been used in cosmetics. Patent Document 9 describes several compounds containing nitrogen, phosphorus, or sulfur as effective platinum catalyst deactivators. However, all of these compounds have poor solubility in ethanol and are added as aqueous solutions. Therefore, when dealing with compounds that are poorly soluble in water, the platinum catalyst deactivator does not mix well and is less effective.

[0011] The present invention is described in detail below. In the present invention, ingredient names may be written using the cosmetic label name or the International Nomenclature of Cosmetic Ingredients (INCI). When the cosmetic label name corresponds to the INCI, the cosmetic label name or the English name may be omitted. The cosmetic of the present invention is a cosmetic comprising a liquid containing: (A) an organohydrogenpolysiloxane having one or more hydrosilyl groups per molecule; (B) an organic compound having one or more alkenyl groups per molecule capable of addition reacting with hydrosilyl groups; (C) a crosslinked product of component (A) and component (B) obtained by addition reaction in the presence of an addition reaction catalyst; (D) an amino acid or amino acid derivative; and (E) a solvent.

[0012] [Component (A)] Component (A) of the present invention is an organohydrogenpolysiloxane having one or more hydrosilyl groups per molecule, and can be used alone or in combination of two or more. The weight-average molecular weight is preferably in the range of 1,000 to 30,000, and more preferably in the range of 3,000 to 15,000 in terms of performance and workability such as filtration. The weight-average molecular weight can be determined as the weight-average molecular weight converted into polystyrene by gel permeation chromatography (GPC) analysis.

[0013] The component (A) is a compound represented by the following formula (1): [In the formula, R 1 are independently a hydrogen atom and a group selected from an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, and an aralkyl group having 7 to 20 carbon atoms. 2 are independently a polyoxyalkylene-containing monovalent hydrocarbon group and a polyhydric alcohol-containing monovalent hydrocarbon group, and the R 1and at least one of them is a polyoxyalkylene-containing monovalent hydrocarbon group or a polyhydric alcohol-containing monovalent hydrocarbon group. 3 are independently an organopolysiloxane-containing group, and the R 1 and at least one of them is an organopolysiloxane-containing group. a1, a2, a3, b, c, and d are selected such that 0<a1≦200, 0≦a2≦50, 0≦a3≦50, 0≦b≦200, 0≦c≦100, and 0≦d≦300. However, they are selected so as to have one or more hydrosilyl groups in the molecule, and the bonding order of the siloxane units may be block or random.]

[0014] In the above formula (1), R 1 are independently a hydrogen atom and a group selected from an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, and an aralkyl group having 7 to 20 carbon atoms. Among these, an alkyl group, an aryl group, an aralkyl group, and a fluoroalkyl group having 1 to 10 carbon atoms are preferred. More specifically, examples include a methyl group, an ethyl group, a propyl group, a butyl group, a pentyl group, a cyclopentyl group, a cyclohexyl group, a phenyl group, a tolyl group, and a trifluoropropyl group. An alkyl group having 1 to 5 carbon atoms, a phenyl group, or a trifluoropropyl group is particularly preferred. In addition, R 1 may contain one or more groups selected from a hydroxyl group or an alkoxy group having 1 to 8 carbon atoms. 1 At least one, preferably one to two, of these are hydrogen atoms.

[0015] a1, a2, a3, b, c, and d are within the following ranges. 0<a1≦200, preferably 1≦a1≦100, and more preferably 1≦a1≦60. 0≦a2≦50, preferably 0≦a2≦20, and more preferably 0≦a2≦10. From the viewpoint of increasing the melting point of the crosslinked product and further enhancing film-formability, a2 is preferably 50 or less. 0≦a3≦50, preferably 0≦a3≦20, and more preferably 0≦a3≦10. From the viewpoint of increasing the melting point of the crosslinked product and further enhancing film-formability, a3 is preferably 50 or less. 0≦b≦200, preferably 0≦b≦100, more preferably 0≦b≦80, and even more preferably 0≦b≦50. 0≦c≦100, preferably 0≦c≦80, more preferably 0≦c≦50, and even more preferably 0≦c≦20. 0≦d≦300, preferably 1≦d≦150, more preferably 5≦d≦100, and even more preferably 10≦d≦80.

[0016] In the above formula (1), a branched or resinous organohydrogenpolysiloxane is preferred in which c+d>0 and 0.5≦(a1+a2+a3) / (c+d)≦1.5 is satisfied. A number satisfying 0.7≦(a1+a2+a3) / (c+d)≦1.2 is more preferred. By setting the value of (a1+a2+a3) / d to be equal to or greater than the lower limit, the degree of crosslinking and molecular weight can be suppressed, and gel formation can be further suppressed. By setting the value to be equal to or less than the upper limit, film formability can be further improved.

[0017] In the above formula (1), when c+d>0, the branched or resinous organohydrogenpolysiloxane contains Q units (SiO 4 / 2 ) or T unit (R 1 SiO 2 / 3 ), and M units (R 1 3SiO 1 / 2 ) is an essential structure, and D unit (R 1 2SiO 2 / 2 ) may be in a solid or liquid state at 25°C, but a solid state is preferred from the viewpoint of film-forming properties. Examples include MQ resin, MTQ resin, MDQ resin, and MDTQ resin.

[0018] In the above formula (1), it is preferable that c = d = 0. When c and d are 0, the organohydrogenpolysiloxane does not contain branched components such as T units or Q units, and is a linear molecule composed only of M units and D units. By using a linear organohydrogenpolysiloxane as a raw material, the crosslinked product composed of (A) and (B) can form a flexible coating.

[0019] In the above formula (1), when c = d = 0, b preferably satisfies 0 ≦ b ≦ 50, and particularly preferably 0 ≦ b ≦ 30. When b is within the above range, the crosslinked product of the obtained silicone resin composition is solid at 25°C, and a crosslinked product of the silicone resin composition having particularly excellent film-forming properties can be obtained.

[0020] In addition, in the above formula (1), c = d = 0, b satisfies 0≦b≦30, and R 1 When two of the groups are hydrogen atoms, the crosslinked product of the silicone resin composition is solid at 25°C and has particularly excellent film-forming properties. 1 If three or more of these are hydrogen atoms, there is a high possibility that the composition will become gel-like when the diluting solvent is removed. In this case, the composition will have film-forming properties, but will have a gel-like feel.

[0021] In the above formula (1), R 2 are independently a polyoxyalkylene-containing monovalent hydrocarbon group and a polyhydric alcohol-containing monovalent hydrocarbon group, and the R 1 and at least one of them is a polyoxyalkylene-containing monovalent hydrocarbon group or a polyhydric alcohol-containing monovalent hydrocarbon group. 2 3SiO 1 / 2 In each of the units, one or more R 2 is a polyoxyalkylene-containing monovalent hydrocarbon group or a polyhydric alcohol-containing monovalent hydrocarbon group. 2 A part of these may be hydroxyl groups.

[0022] The above R 2 In the formula (6), the polyoxyalkylene-containing monovalent hydrocarbon group is preferably a group represented by the following formula (6): [In the formula, R 5are independently a group selected from a hydrogen atom and a monovalent hydrocarbon group having 1 to 6 carbon atoms, k1 is an integer satisfying 0≦k1≦15, and g1, g2, and g3 are integers satisfying 0≦g1<200, 0≦g2<200, 0≦g3<200, and 0<g1+g2+g3≦200. The bonding order of the oxyalkylene units bounded by g1, g2, and g3 may be block or random.]

[0023] In the above formula (6), R 5are independently a group selected from a hydrogen atom and a monovalent hydrocarbon group having 1 to 6 carbon atoms, preferably a hydrogen atom, a methyl group, an ethyl group, or a butyl group, and more preferably a hydrogen atom or a methyl group. g1 satisfies 0≦g1<200, preferably 1≦g1≦100, more preferably 2≦g1≦50, and even more preferably 3≦g1≦40. If g1 is greater than the upper limit, the hydrophilicity may be too high, resulting in a risk of poor emulsion stability. g2 satisfies 0≦g2<200, preferably 0≦g2≦100, more preferably 0≦g2≦50, and even more preferably 0≦g2≦30. It is particularly preferably 0, and if not 0, it is particularly preferably 1≦g2≦10. If g2 is greater than the upper limit, the hydrophilicity may be too high, resulting in a risk of poor emulsion stability. g3 is 0≦g3<200, preferably 0≦g3≦100, more preferably 0≦g3≦50, and even more preferably 0≦g3≦30. It is particularly preferably 0, and if not 0, it is preferably 1≦g3≦10. If g3 is greater than the upper limit, the hydrophilicity may be too high, resulting in a risk of poor emulsion stability. g1+g2+g3 is 0<g1+g2+g3≦200, preferably 1≦g1+g2+g3≦100, more preferably 8≦g1+g2+g3≦50, and even more preferably 8<g1+g2+g3≦40. Alternatively, g1+g2+g3 is 0<g1+g2+g3≦40. If g1+g2+g3 is less than the lower limit, the hydrophilicity may be poor, emulsifying properties may be weak, and stability may be poor. If g1+g2+g3 is greater than the upper limit, the hydrophilicity may be too high. In order to impart sufficient hydrophilicity to obtain a water-in-oil emulsion, it is preferable that g1 / (g2+g3)≧1, and in order to impart sufficient hydrophobicity to obtain an oil-in-water emulsion, it is preferable that g1 / (g2+g3)≦1. When the polyoxyalkylene moiety is composed of two or more of ethylene oxide units, propylene oxide units, and butylene oxide units, it may be either a block copolymer or a random copolymer of these two or more units.

[0024] The above R 2In the formula (I), the polyhydric alcohol-containing monovalent hydrocarbon group is a monovalent hydrocarbon group having two or more hydroxyl groups, some or all of which may be alkoxylated with alkyl groups having 1 to 6 carbon atoms. Among these, a group represented by the following formula (7) is preferred: [In the formula, R 5’ are independently a group selected from a hydrogen atom and a monovalent hydrocarbon group having 1 to 6 carbon atoms, and m, n1, and n2 are integers satisfying the conditions 1≦m≦10, 0≦n1≦5, and 1≦n2≦5.

By setting n1 to the upper limit or less, the possibility of gelation can be reduced. n2 is 1≦n2≦5, preferably 1≦n2≦3, and more preferably 1≦n2≦2. If n2 is greater than the upper limit, the hydrophilicity may be too high, resulting in a lack of emulsion stability.

[0026] In the above formula (1), R 3 are independently groups selected from organopolysiloxane-containing groups. Examples of organopolysiloxane-containing groups include groups represented by the following general formulas (8) to (11). 3 3SiO 1 / 2 In each of the units, one or more R 3 is an organopolysiloxane-containing group. 3 A part of these may be hydroxyl groups.

By setting i to 500 or less, the film formability is further improved. j1 to j3 are each an integer of 0 or more and 2 or less.

[0028] [Component (B)] The component (B) of the present invention is an organic compound having one or more alkenyl groups per molecule that are capable of addition reacting with a hydrosilyl group (B).

These are described in detail below. The weight-average molecular weight of component (B) is preferably in the range of 1,000 to 30,000, and more preferably in the range of 3,000 to 15,000 in terms of performance and workability, such as filtration.

[0029] The component (B) is a compound represented by the following formula (2): [In the formula, R 4 are independently a group selected from an alkenyl group having 2 to 20 carbon atoms, an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, and an aralkyl group having 7 to 20 carbon atoms. p, q, r, and s satisfy the following conditions: 0<p≦200, 0≦q≦200, 0≦r≦100, and 0≦s≦300.

More specific examples include methyl groups, ethyl groups, propyl groups, butyl groups, pentyl groups, cyclopentyl groups, cyclohexyl groups, phenyl groups, tolyl groups, and trifluoropropyl groups. Among these, an alkyl group having 1 to 5 carbon atoms, a phenyl group, or a trifluoropropyl group is preferred. 2 A part of the group may contain one or more groups selected from a hydroxyl group and an alkoxy group having 1 to 8 carbon atoms.

[0031] In the above formula (2), p, q, r, and s are in the following ranges: 0<p≦200, preferably 1≦p≦100, and more preferably 1≦p≦60. 0≦q≦200, preferably 0≦q≦100, and more preferably 0≦q≦50. 0≦r≦100, preferably 0≦r≦50, and more preferably 0≦r≦20. 0≦s≦300, preferably 1≦s≦150, and more preferably 0≦s≦80.

[0032] In the above formula (2), when q = r = 0 and the numbers satisfy 0.5≦p / s≦1.5, the resulting organohydrogenpolysiloxane is a resinous organohydrogenpolysiloxane. A number that satisfies 0.7≦p / s≦1.2 is preferred. By setting the p / s value to be equal to or greater than the lower limit, gel formation can be suppressed, and by setting it to be equal to or less than the upper limit, film-forming properties can be further improved.

[0033] In the above formula (2), when r and s are 0, the alkenyl group-containing organopolysiloxane does not contain branched components such as T units or Q units, and is a linear molecule composed only of M units and D units. By using a linear alkenyl group-containing organopolysiloxane as a raw material, the crosslinked product composed of (A) and (B) can form a flexible coating.

[0034] In the above formula (2), r = s = 0, and the following formula (3) [In the formula, R 4 , q is the same as above, and k is an integer satisfying 0≦k≦5.]

[0035] In the above formula (3), q is preferably 0≦q≦50, and more preferably 0≦q≦30. When q is within the above range, the resulting crosslinked product of the silicone resin composition is solid at 25°C, and a crosslinked product of the silicone resin composition having particularly excellent film-forming properties can be obtained. When q is greater than 50, there is a high possibility that the product will become gel-like when the diluent solvent is removed. In this case, the product has film-forming properties and a gel-like feel.

[0036] When the component (A) is a linear organohydrogenpolysiloxane in which c = d = 0 in the formula (1) and the component (B) is a branched or resinous alkenyl-containing organopolysiloxane in which r + s > 0 in the formula (2) and 0.5 ≦ p / (r + s) ≦ 1.5 is satisfied, containing one or more alkenyl groups per molecule, the crosslinked product tends to be solid and easily soluble in volatile solvents, resulting in a strong, non-sticky coating.

[0037] [Polyoxyalkylene Ether Having Alkylene Groups at Both Ends] Examples of polyoxyalkylene ethers having alkylene groups at both ends include those represented by the following formula (4). [In the formula, k1 is an integer of 0≦k1≦15, and e1, e2, and e3 are numbers that satisfy the following conditions: 0≦e1<200, 0≦e2<200, 0≦e3<200, and 0<e1+e2+e3≦200. The bonding order of the oxyalkylene units bounded by e1, e2, and e3 may be block or random.]

[0038] In the above formula (4), e1 is 0≦e1<200, preferably 1≦e1≦100, more preferably 2≦e1≦50, and even more preferably 3≦e1≦40. If e1 is greater than the above upper limit, the hydrophilicity may be too high, which may result in a lack of emulsion stability. e2 is 0≦e2<200, preferably 0≦e2≦100, more preferably 0≦e2≦50, and even more preferably 0≦e2≦30. Particularly preferably, it is 0, and if it is not 0, it is preferably 1≦e2≦10. If e2 is greater than the above upper limit, the hydrophilicity may be too high, which may result in a lack of emulsion stability. e3 is 0≦e3<200, preferably 0≦e3≦100, more preferably 0≦e3≦50, and even more preferably 0≦e3≦30. Particularly preferably, it is 0, and if it is not 0, it is preferably 1≦e3≦10. If e3 is greater than the upper limit, the hydrophilicity will be too high, which may result in a lack of emulsion stability. e1 + e2 + e3 is 0 < e1 + e2 + e3 ≦ 200, preferably 1 ≦ e1 + e2 + e3 ≦ 100, more preferably 8 ≦ e1 + e2 + e3 ≦ 50, and even more preferably 8 < e1 + e2 + e3 ≦ 40. Alternatively, 0 < e1 + e2 + e3 ≦ 40. If e1 + e2 + e3 is less than the lower limit, the hydrophilicity will be poor, emulsifying ability will be weak, and emulsion stability may be poor. If e1 + e2 + e3 is greater than the upper limit, the hydrophilicity will be too high, which may result in poor emulsion stability. In order to impart sufficient hydrophilicity to obtain a water-in-oil emulsion, it is preferable that e1 / (e2+e3)≧1, and in order to impart sufficient hydrophobicity to obtain an oil-in-water emulsion, it is preferable that e1 / (e2+e3)≦1. When the polyoxyalkylene moiety is composed of two or more of ethylene oxide units, propylene oxide units, and butylene oxide units, it may be either a block copolymer or a random copolymer of these two or more units.

[0039] By using a polyoxyalkylene ether containing alkylene groups at both ends as a raw material for the above component (B), the crosslinked product consisting of (A) and (B) exhibits emulsifying properties and can be used as an emulsifier for water-in-oil emulsions or oil-in-water emulsions. In addition, since the group represented by formula (4) has a low glass transition temperature, it can impart flexibility to the crosslinked product.

[0040] [Terminal Allyl Group-Modified Polyglycerol Ether] Examples of polyglycerol ethers having one or more allyl groups at the terminals include those represented by the following formula (5), which are terminal allyl group-modified polyglycerol ethers. [In the formula, m' is an integer satisfying 1≦m'≦10, n1' is an integer satisfying 0≦n1'≦5, and n2' is an integer satisfying 1≦n2'≦5.]

[0041] In the above formula (5), m' is 1≦m'≦10, preferably 1≦m'≦8, and more preferably 1≦m'≦5. If m' is greater than the above upper limit, the hydrophilicity may be too high, which may result in a lack of emulsion stability. n1' is 0≦n1'≦5, preferably 0≦n1'≦3, and more preferably 0≦n1'≦1. n1' is even more preferably 0, and if not 0, preferably 0<n1'≦1. If n1' is greater than the above upper limit, the crosslinking component may be too high, which may increase the possibility of gelation. n2' is 1≦n2'≦5, preferably 1≦n2'≦3, and more preferably 1≦n2'≦2. If n2' is greater than the above upper limit, the hydrophilicity may be too high, which may result in a lack of emulsion stability.

[0042] By using a polyglycerol ether modified with allyl groups at both ends as a raw material for the above component (B), the crosslinked product consisting of component (A) and component (B) exhibits emulsifying properties and can be used as an emulsifier for water-in-oil emulsions or oil-in-water emulsions.In addition, the group represented by formula (5) has a hydrogen-bonding functional group compared to formula (4), so it has a higher glass transition point and can impart rigidity to the organosilicon resin.Therefore, by changing the ratio of the group represented by formula (4) and the group represented by formula (5), it is possible to control the physical properties of the crosslinked product.

[0043] When the component (B) is a polyoxyalkylene ether having alkylene groups at both ends, as represented by formula (4), or a polyglycerol ether modified with allyl groups at both ends, as represented by formula (5), the HLB calculated by the Griffin method is preferably 0.1 to 15. In particular, for use as a water-in-oil emulsifier, the HLB value is preferably 0.1 to 8.0, more preferably 0.1 to 6.0, and even more preferably 0.5 to 4.5. The Griffin method defines the HLB value as 20 x (sum of molecular weights of hydrophilic moieties / total molecular weight). The HLB value is a numerical value that represents the affinity of a surfactant for water and oil.

[0044] The amount of component (B) is preferably an amount such that the molar ratio of hydrosilyl groups in component (A) to alkenyl groups in component (B) (hydrosilyl groups / alkenyl groups) falls within a range of 0.5 to 1.5, preferably 0.5 to 1.2, more preferably 0.8 to 1.2, and even more preferably 0.9 to 1.1.

[0045] [Component (C)] Component (C) of the present invention is an addition reaction catalyst and is necessary to promote the addition reaction between components (A) and (B). Examples of component (C) include platinum catalysts and rhodium catalysts. Among these, chloroplatinic acid, alcohol-modified chloroplatinic acid, and chloroplatinic acid-vinylsiloxane complexes are preferred. Furthermore, since an excessive amount of component (C) will cause coloration of the sample, the amount of component (C) is preferably 50 ppm or less, and more preferably 20 ppm or less, in terms of platinum or rhodium atom mass, relative to the total amount of components (A) and (B).

[0046] [Component (D)] The component (D) of the present invention is an amino acid or an amino acid derivative, and functions as an inactivator of the remaining component (C). As component (D), L-proline, an L-proline derivative, or an amino acid ester hydrochloride is preferred.

[0047] Examples of L-proline derivatives include L-proline methyl ester hydrochloride, N-tert-butoxycarbonyl-L-proline methyl ester, L-prolinamide, N-tert-butoxycarbonyl-L-proline, hydroxy-L-proline, α-methyl-L-proline, etc. Examples of amino acid ester hydrochlorides include glycine methyl ester hydrochloride, methionine methyl ester hydrochloride, lysine methyl ester hydrochloride, cysteine ​​methyl ester hydrochloride, arginine methyl ester hydrochloride, serine methyl ester hydrochloride, tyrosine methyl ester hydrochloride, valine methyl ester hydrochloride, and alanine methyl ester hydrochloride. Among these, L-proline is preferred from the viewpoints of the safety of component (D) and effectiveness in forming a crosslinked product of the silicone resin composition, and methionine methyl ester, methionine methyl ester hydrochloride, cysteine ​​methyl ester hydrochloride, and methionine methyl ester hydrochloride are preferred from the viewpoint of effectiveness in forming a crosslinked product. Although L-proline methyl ester hydrochloride, given above as an example of the L-proline derivative, is also an amino acid ester hydrochloride, it is classified as an L-proline derivative in the present invention.

[0048] The component (D) is preferably a component that is soluble in ethanol at 25°C. In the present invention, "soluble in ethanol" means that a 1% by mass solution (component (D) : ethanol = 1:99) is considered soluble if it is colorless and transparent. When adding a water-soluble solid component to a silicone compound, adding it in the form of an aqueous solution will not result in compatibility, so adding it in the form of a solution that is compatible with silicone, such as an ethanol solution, will have a better effect on deactivating the catalyst.

[0049] The amount of component (C) blended is preferably an amount such that the molar ratio of component (C) to component (D) ((C):(D)) is 1:0.5 to 1:5, more preferably 1:0.8 to 1:3, and even more preferably 1:0.8 to 1:2. By ensuring that the amount is equal to or greater than the lower limit, the purpose of blending component (D) can be achieved, and by ensuring that the amount is equal to or less than the upper limit, scission of the siloxane bonds in the crosslinked product can be prevented, and a decrease in molecular weight can be prevented.

[0050] [Component (E)] The solvent in the liquid is not particularly limited, and examples thereof include cyclic organopolysiloxanes such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane; aromatic hydrocarbons such as toluene and xylene; ketone-based organic solvents such as acetone, methyl ethyl ketone, diethyl ketone, and methyl isobutyl ketone; aliphatic hydrocarbons such as hexane, heptane, octane, and cyclohexane; and aliphatic alcohols such as methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-methyl-1-propanol, 2-butanol, 2-methyl-2-propanol, 1-pentanol, 2-methylbutanol, 2-pentanol, 1-hexanol, 2-methylpentanol, 1-heptanol, 1-octanol, 1-nonanol, 1-decanol, phenol, benzyl alcohol, ethylene glycol, and 1,2-propylene glycol.

[0051] The component (E) in the liquid may be the solvent used in producing the crosslinked product described below, or another solvent may be added after the solvent used in producing the crosslinked product has been distilled off or removed. The amount of the solvent (E) in the liquid is appropriately selected from 1 to 80% by mass. The amount of the crosslinked product in the liquid is appropriately selected from 20 to 99% by mass. The liquid is not particularly limited and may be a solution or a dispersion, but a solution is preferred.

[0052] [Physical Properties of Crosslinked Product] The crosslinked product of the present invention is a crosslinked product (addition reaction crosslinked product) between the above-mentioned components (A) and (B) which have been subjected to an addition reaction in the presence of an addition reaction catalyst (C). The crosslinked product is preferably soluble at 25°C in a volatile oil having a boiling point of 250°C or less at 1,013 hPa. The weight-average molecular weight of the crosslinked product of the present invention is preferably 5,000 to 1,000,000, more preferably 8,000 to 800,000, and even more preferably 10,000 to 600,000. Having a molecular weight within this range is more preferable in terms of performance and workability, such as filtration. By setting the weight-average molecular weight to 5,000 or more, the flexibility of the formed film is further enhanced. On the other hand, by setting the weight-average molecular weight to 1,000,000 or less, the possibility of gel formation can be further reduced. In the present invention, the weight average molecular weight of the crosslinked product can be determined as a polystyrene-equivalent weight average molecular weight in gel permeation chromatography (GPC) analysis under the following conditions (the same applies hereinafter). The following two types of developing solvents can be used depending on the refractive index of the crosslinked product of the silicone resin composition. In the present invention, when component (B) is of formula (3), measurement condition 1, in which the developing solvent is toluene, was used, and when component (B) is of formula (4) or (5), measurement condition 2, in which the developing solvent is tetrahydrofuran, was used.

[0053] [Measurement Condition 1] Developing solvent: toluene Flow rate: 0.6 mL / min Detector: differential refractive index detector (RI) Detector temperature 40°C Column: TSK Guard column Super H-H TSKgel Super H5000 (6.0 mm I.D. x 15 cm x 1) TSKgel Super H4000 (6.0 mm I.D. x 15 cm x 1) TSKgel Super H3000 (6.0 mm I.D. x 15 cm x 1) TSKgel Super H2000 (6.0 mm I.D. x 15 cm x 1) (all manufactured by Tosoh Corporation) Column temperature: 40°C Sample injection volume: 50 μL (toluene solution with a concentration of 0.3% by mass)

[0054] [Measurement Condition 2] Developing solvent: tetrahydrofuran (THF) Flow rate: 0.6 mL / min Detector: differential refractive index detector (RI) detector temperature 40°C Column: TSK Guard column Super H-H TSKgel Super HM-N (6.0 mm I.D. × 15 cm × 1) TSKgel Super H2500 (6.0 mm I.D. × 15 cm × 1) (all manufactured by Tosoh Corporation) Column temperature: 40°C Sample injection volume: 50 μL (THF solution with a concentration of 0.3% by mass)

[0055] The crosslinked product may be solid, gel-like, or liquid at 25°C. For example, a film can be easily formed by dissolving it in a liquid oil and volatilizing it. From the viewpoint of film-forming ability, a solid or gel-like form is preferred, and a solid form is more preferred. The film-forming ability can be determined by dropping 1.5 g of a solution diluted to 30% by mass with isododecane or decamethylcyclopentasiloxane onto PTFE (fluororesin), drying it at 105°C for 3 hours, and determining whether a free-standing film is formed. If a film is not formed, oil will seep out from cracks in the film, significantly reducing oil resistance and resulting in poor skin conformability, resulting in an unnatural finish.

[0056] The crosslinked product of the present invention can be more suitably used as a film-forming agent. Component (B) before crosslinking forms a strong, brittle film, while the crosslinked product after crosslinking has improved brittleness and forms a flexible film without stickiness. This is because component (B) before crosslinking forms a film, but crosslinking with flexible chains imparts flexibility to the film. Generally, hard films tend to have low flexibility, while highly flexible films tend to be soft, so film strength and flexibility have been considered to be in a trade-off relationship. However, the crosslinked product of the silicone resin composition of the present invention has the characteristic of having excellent conformability due to its high flexibility despite forming a strong film.

[0057] In addition, the film formed by the crosslinked product has significantly improved oil resistance to oil agents such as sebum, compared to the film formed by component (B) before crosslinking.Organosilicon resins tend to have improved oil resistance as their molecular weight increases, but since there is a limit to how much the molecular weight of organosilicon resins can be increased, there is also a limit to the oil resistance.The crosslinking of component (B) by a crosslinking agent leads to a pseudo increase in the molecular weight of the organosilicon resin, and therefore has the effect of raising the limit.Therefore, the crosslinked product of the silicone resin composition has oil resistance that cannot be achieved by conventional organosilicon resins.

[0058] The amount of hydrogen gas generated per mass from the crosslinked product of the present invention under standard conditions is 1.5 mL or less. If the amount exceeds 1.5 mL / g, the crosslinked product may generate hydrogen gas over time or react with the remaining hydroxyl or alkoxy groups and hydrosilyl groups, increasing the possibility of viscosity increase over time and deteriorating stability over time. The amount of hydrogen gas generated is preferably 0.01 to 1.2 mL / g, and more preferably 0.02 to 1.0 mL / g.

[0059] The amount of hydrogen gas per mass can be calculated from the volume of hydrogen gas generated by the reaction of hydrosilyl groups with a base. Examples of the calculation method include, but are not limited to, the following method. <Method for measuring the amount of hydrogen gas> 10 g of a 20 mass % aqueous sodium hydroxide solution is added dropwise to a mixed solution of 50 g of a cross-linked product of a silicone resin composition diluted to 50 mass % with decamethylcyclopentasiloxane and 10 g of 1-butanol. The amount of hydrogen gas per mass can be determined by dividing the volume of the generated hydrogen gas by the pure content of the cross-linked product of the silicone resin composition.

[0060] [Manufacturing Method] Crosslinked products can be synthesized by various methods known in the art. For example, crosslinking can be achieved by reacting the surface silanol groups of an organosilicon resin with an organopolysiloxane having hydroxyl groups at both ends, a polyoxyalkylene-containing group, or a polyhydric alcohol-containing hydrocarbon group. However, since it is difficult to completely control the amount of silanol groups on the surface of the organosilicon resin, there is a problem in that it is difficult to accurately control the amount of organopolysiloxane, polyoxyalkylene-containing group, or polyhydric alcohol-containing hydrocarbon group to be crosslinked. Therefore, examples of methods for producing the crosslinked product include a method for producing the crosslinked product, which includes the steps of: (A) subjecting an organohydrogenpolysiloxane having one or more hydrosilyl groups per molecule, and (B) an organic compound having one or more alkenyl groups per molecule that are capable of undergoing an addition reaction with the hydrosilyl groups, to an addition reaction in the presence of an addition reaction catalyst (C) to obtain a crosslinked product of component (A) and component (B); and then (D) adding an amino acid or an amino acid derivative to a reaction solution of the crosslinked product.

[0061] The method for producing a crosslinked product obtained by the above-mentioned addition reaction (hydrosilylation reaction) is described in more detail below. In the hydrosilylation reaction step between the above-mentioned component (A), an organohydrogenpolysiloxane having one or more hydrosilyl groups per molecule, and (B), an organic compound having one or more alkenyl groups per molecule capable of undergoing an addition reaction with hydrosilyl groups, the molar ratio of terminal hydrosilyl groups to alkenyl groups can be selected from the range of 0.5 to 1.5, preferably 0.5 to 1.2 moles, more preferably 0.8 to 1.2, and even more preferably 0.9 to 1.1. If this ratio is too large, the amount of residual hydrosilyl groups will increase, potentially reducing stability over time. This addition reaction is carried out in the presence of (C), an addition reaction catalyst.

[0062] Furthermore, the addition reaction may be carried out in the presence of a solvent (solution) as needed. Examples of the solvent include the solvent (E) described above. Among these, ethanol, 1-propanol, and 2-propanol are preferred from the viewpoint of reactivity.

[0063] The amount of the solvent used is preferably 1 to 80% by mass, more preferably 5 to 50% by mass, of the entire reaction solution (system). Within this range, the reaction system is maintained uniformly, and the reaction proceeds efficiently.

[0064] The addition reaction conditions are not particularly limited, but it is preferable to heat under reflux at a temperature of 50 to 150°C, more preferably 80 to 120°C, for about 1 to 10 hours.

[0065] It is also possible to include a step of removing the rhodium catalyst or platinum catalyst used with activated carbon after the addition reaction. The amount of activated carbon used is preferably 0.001 to 5.0 mass % of the entire system, and more preferably 0.01 to 1.0 mass %. If the amount is within this range, coloration of the sample can be further suppressed.

[0066] After the addition reaction, a step of removing the remaining hydrosilyl groups can be included as needed. In particular, when used in applications such as cosmetics, the hydrosilyl groups may be deactivated over time by dehydrogenation. Since hydrogen gas is generated, which is a safety issue, it is preferable to include a step of removing the hydrosilyl groups.

[0067] The hydrosilyl group removal process involves adding a basic catalyst to hydrolyze unreacted hydrosilyl groups, followed by neutralization by adding an acidic catalyst in an amount equal to the molar equivalent of the basic catalyst. Examples of basic catalysts include strongly basic catalysts and weakly basic catalysts. Examples of strongly basic catalysts include alkali metal hydroxides such as lithium hydroxide, sodium hydroxide, potassium hydroxide, calcium hydroxide, and barium hydroxide. Examples of weakly basic catalysts include alkali metal carbonates such as sodium carbonate and calcium carbonate, and alkali metal bicarbonates such as sodium bicarbonate and potassium bicarbonate. In terms of promoting the dehydrogenation reaction, it is particularly preferable to use a strongly basic catalyst, and specifically, sodium hydroxide is preferred. Examples of acidic catalysts include inorganic acids such as hydrochloric acid, sulfuric acid, sulfurous acid, oleum, and phosphoric acid; sulfonic acids such as p-toluenesulfonic acid, methanesulfonic acid, and trifluoromethanesulfonic acid; and carboxylic acids such as oxalic acid, formic acid, acetic acid, propionic acid, benzoic acid, citric acid, and trifluoroacetic acid.

[0068] In general, rather than using an acid or base alone, it is preferable to use them in combination with water and heat them at a temperature below the boiling point of water. This process converts hydrosilyl groups (SiH groups) into hydroxysilyl groups (SiOH groups). However, when a crosslinked product of a silicone resin composition is treated with a base catalyst, the silanol groups and alkoxy groups in the organosilicon resin react, causing changes in physical properties, so it is not preferable to remove hydrosilyl groups using this method.

[0069] The crosslinked product suffers from the problem of increased viscosity and hydrogen gas generation due to the reaction of remaining unreacted functional groups over time. While stability over time can be improved by limiting the amount of hydrogen gas generated per mass from the crosslinked product of the silicone resin composition to 1.5 mL or less under standard conditions, it is difficult to completely remove the unreacted functional groups. Therefore, when stored for a long period of time or at high temperatures, viscosity gradually increases and hydrogen gas generation occurs. This is due to the addition reaction catalyst (C) remaining in the crosslinked product. While adsorption and removal using porous materials such as activated carbon is possible, complete removal is difficult and does not result in improved stability over time. Adding the above-mentioned component (D) to the crosslinked product makes it possible to deactivate the addition reaction catalyst (C) and inhibit the reaction of remaining unreacted functional groups over time.

[0070] The amount of component (D) added is preferably 1:0.5 to 1:5 in terms of molar ratio ((C):(D)), more preferably 1:0.8 to 1:3, and even more preferably 1:0.8 to 1:2. The addition is preferably performed as a solution. In this case, the solvents listed above for component (E) can be used, with ethanol being preferred. By adding the solution, the dissolved component (D) becomes compatible with components (A) and (B), which is thought to efficiently inactivate the addition reaction catalyst (C) and further improve stability over time. A step of removing component (E) after the reaction may be included. An example of such a removal step is heating under reduced pressure. The heating temperature is not particularly limited and can be selected appropriately depending on the component (E) used.

[0071] [Cosmetics] A cosmetic is prepared by blending a liquid containing the crosslinked product of the present invention (crosslinking reaction product, hereinafter sometimes referred to as component (a)), (D) an amino acid or amino acid derivative, and (E) a solvent, and by including this, the cosmetic acts as a film-forming agent, is not sticky when applied, has an excellent feel when used, has good water resistance and oil resistance, and has good adhesion to the skin, and therefore, spreads well, has excellent finish, water resistance, oil resistance, and cosmetic wear (sustainability), and has excellent abrasion resistance such as secondary adhesion prevention effect.

[0072] The blending amount of the liquid of the present invention is not particularly limited and is appropriately selected from 1 to 99% by mass of the total cosmetic. The blending amount of the crosslinked product (a) of the present invention is preferably in the range of 0.1 to 40% by mass of the total cosmetic, and more preferably in the range of 0.1 to 10% by mass. If it is less than 0.1% by mass, sufficient oil resistance may not be obtained, and if it is more than 40% by mass, the feel during use may be poor. The amounts of (D) amino acid or amino acid derivative and (E) solvent are determined within the ranges described above based on the amount of component (a).

[0073] [Method for Producing Cosmetics] Examples of methods for producing cosmetics include a method for producing cosmetics comprising the steps of: (A) subjecting an organohydrogenpolysiloxane having one or more hydrosilyl groups per molecule, and (B) an organic compound having one or more alkenyl groups per molecule capable of addition reacting with the hydrosilyl groups to an addition reaction in the presence of an addition reaction catalyst to obtain a crosslinked product of component (A) and component (B); and (D) adding an amino acid or amino acid derivative to the reaction solution of the crosslinked product; and (E) blending the crosslinked product obtained. The addition reaction may be carried out in the presence of a solvent (solution) if necessary. Examples of the solvent include the solvent (E) described above. The crosslinked product obtained by the above production method may be blended in cosmetics in either a liquid or non-liquid form, but a liquid form is preferred from the viewpoint of ease of blending.

[0074] The crosslinked product can be incorporated into the cosmetic preparation in various ways. For example, it may be dissolved in component (E) in advance to form a solution, or it may be dried using a spray dryer or the like to make the solid content easily redissolved, or it may be incorporated into the cosmetic preparation as an O / W emulsion.

[0075] The crosslinked product of the present invention may be used as an intermediate composition by preparing an O / W emulsion, in view of the convenience of blending it into aqueous or emulsion-based compositions. That is, an O / W emulsion in which a solution of the optional oil agent of the crosslinked product of the present invention is dispersed as a dispersed phase in an aqueous phase, which is a continuous phase, serves as the intermediate composition. The method for preparing this O / W emulsion is not particularly limited, and it can be prepared by a known method. For example, it can be prepared by emulsifying using one surfactant having an HLB of 10 or more, either alone or in combination of two or more surfactants. A surfactant having an HLB of less than 10, a higher alcohol, or the like may also be used as a stabilizer. Furthermore, the aqueous phase may be thickened by using a carbomer or the like.

[0076] The crosslinked product can be dissolved in any solvent and provided as a dissolved product. When the solvent is a volatile oil having a boiling point of 250°C or less at 1,013 hPa, the solvent volatilizes, allowing the formation of a film, thereby further enhancing the effect as a film-forming agent. As the volatile oil having a boiling point of 250°C or less at 1,013 hPa, one or more selected from silicone oil, isododecane, and ethanol are preferred, and one or more can be used alone or in combination.

After confirming the reaction, 56.0 g of polyglycerol having allyl groups at both ends, represented by the following formula (E18), and 766.7 g of 2-propanol were added and heated at 80 ° C. for 3 hours.

[0150] Example 9 A decamethylcyclopentasiloxane solution of a crosslinked organosilicon resin was obtained in the same manner as in Example 2, except that the 1% L-proline / ethanol solution was replaced with a 1% aqueous glycine solution.

[0151] Example 10 A decamethylcyclopentasiloxane solution of a crosslinked organosilicon resin was obtained in the same manner as in Example 3, except that the 1% ethanol solution of L-methionine methyl ester hydrochloride was replaced with a 1% aqueous L-methionine solution.

[0152] Comparative Example 1 A decamethylcyclopentasiloxane solution of a crosslinked organosilicon resin was obtained in the same manner as in Example 1, except that the step of adding the 1% L-proline / ethanol solution was omitted.

[0153] Comparative Example 2 A decamethylcyclopentasiloxane solution of a crosslinked organosilicon resin was obtained in the same manner as in Example 5, except that the step of adding the 1% L-proline / ethanol solution was omitted.

[0154] The molar ratios of (D) amino acids or amino acid derivatives, (C) addition reaction catalysts, and (D) used in the above examples and comparative examples are shown in Table 1 below.

[0155]

[0156] <Stability over Time> The decamethylcyclopentasiloxane solutions of the crosslinked organosilicon resins obtained in the above Examples and Comparative Examples were stored in a thermostatic chamber at 50°C. Viscosity measurements were taken after 2 weeks, 1 month, and 6 months, and the stability was evaluated according to the following criteria. The results are shown in Table 1. Evaluation was based on viscosity values ​​relative to the viscosity immediately after production, which was taken as 100%. Viscosity was measured using a Cannon-Fenske viscometer according to the method described in JIS Z 8803:2011, with the solution returned to 25°C. Excellent: The difference between the viscosity immediately after production and the viscosity after storage at 50°C was less than 3%. Good: The difference between the viscosity immediately after production and the viscosity after storage at 50°C was 3% or more but less than 5%. Fair: The difference between the viscosity immediately after production and the viscosity after storage at 50°C was 5% or more but less than 10%. Bad: The difference between the viscosity immediately after production and the viscosity after storage at 50°C was 10% or more. A rating of "Fair" or better was considered acceptable.

[0157]

[0158] In all of Examples 1 to 10, the difference in viscosity between immediately after production and two weeks later was less than 3% (based on the viscosity value immediately after production), demonstrating good stability over time. In particular, the stability over time was better when L-proline and L-methionine methyl ester hydrochloride were added as an ethanol solution. Furthermore, the stability over time was better when added as an ethanol solution than when added as an aqueous solution. Comparative Examples 1 and 2 are examples where the product was finished without adding (D) an amino acid or amino acid derivative. The remaining functional groups gradually reacted with each other over time, resulting in an increase in viscosity, and after six months the difference in viscosity was 10% or more.

[0159] The crosslinked organosilicon resins obtained in the above Examples and Comparative Examples were evaluated for shape at 25°C, film-forming ability, and film properties (continuity, hardness, flexibility) immediately after production and after six months of storage in a thermostatic oven at 50°C according to the methods described below. The results immediately after production are shown in Table 3 below, and the results after six months of storage in a thermostatic oven at 50°C are shown in Table 4 below.

[0160] 1) The decamethylcyclopentasiloxane solution or other solution obtained in the above Examples and Comparative Examples was heated to 120-130°C under reduced pressure, and the decamethylcyclopentasiloxane or other solvent was removed to obtain a crosslinked organosilicon resin. The shape of the resulting resin at 25°C was observed. 2) Film-forming ability was evaluated by dropping 1.5 g of a solution diluted with 30% solvent (isododecane or decamethylcyclopentasiloxane) into a PTFE (fluororesin) container, drying at 105°C for 3 hours, and determining whether a free-standing film formed. 3) Film continuity was evaluated by determining whether the film prepared in 2) above was continuous (i.e., whether it was crack-free). Films without cracks were rated as "continuous." 4) Film hardness was evaluated by determining whether a fingernail could be inserted into the film prepared in 2) above. Films that could be inserted with a fingernail were rated as "soft." 5) The stickiness of the film was evaluated by rating the stickiness of the film prepared in 2) above as "not present" or "present." 6) The flexibility was evaluated by rating whether the film formed on an aluminum dish by the method in 2) above could be bent. If the film cracked, the flexibility was recorded as "not present."

[0161]

[0162] Immediately after production, uniform continuous films were obtained in Examples 1 to 10 and Comparative Examples 1 and 2. The films were neither sticky nor brittle and had high flexibility when bent.

[0163]

[0164] In Examples 1 to 10, which were stored in a thermostatic oven at 50°C for 6 months, uniform continuous films were obtained, and the films were neither sticky nor brittle. Furthermore, the films had high flexibility when bent. Since the film performance did not change from immediately after production, the stability over time was good. On the other hand, in Comparative Examples 1 and 2, the films had low continuity and flexibility. This is thought to be due to an increase in the crosslink density of the crosslinked organosilicon resin caused by the reaction of the remaining functional groups over time.

[0165] For each of the crosslinked organosilicon resin coatings obtained in the above Examples and Comparative Examples immediately after production and after six months of storage in a thermostatic oven at 50°C, 3 μL each of squalane, oleic acid, and triethylhexanoin was dropped, and the contact angle was measured to evaluate oil resistance. The results immediately after production are shown in Table 5 below, and the results after six months of storage in a thermostatic oven at 50°C are shown in Table 6 below.

[0166]

[0167] Immediately after production, Examples 1 to 10 and Comparative Examples 1 and 2 had large contact angles with all of the oils, squalane, oleic acid, and triethylhexanoin, and exhibited high oil resistance.

[0168] The figures in parentheses are the percentage change in contact angle compared to immediately after production.

[0169] All of Examples 1 to 10 stored in a thermostatic oven at 50°C for 6 months had large contact angles with squalane, oleic acid, and triethylhexanoin, demonstrating high oil resistance, and there was no significant change in the rate of increase or decrease in contact angle immediately after production. On the other hand, in Comparative Examples 1 and 2, the oil resistance began to decrease once the contact angle with each oil decreased. This is thought to be due to a decrease in continuity caused by a change in the film properties of the crosslinked organosilicon resin over time.

[0170] Example 11 Method for producing a 30% solution of crosslinked organosilicon resin containing L-proline in isododecane A reactor was charged with 1,000 g of a 50% isododecane solution of a powdered alkenyl group-containing organosilicon resin (weight average molecular weight 7,430, vinyl value: 0.229 mmol / g) represented by the average composition formula (E1) below, 700 g of isododecane, 126.9 g of an organopolysiloxane having hydrosilyl groups at both ends represented by the formula (E2) below (amount of hydrogen gas generated: 20.3 mL / g, hydrosilyl group / vinyl group=1.0), and 3.0 g of a 0.3% ethanol solution of platinum-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex (equivalent to 0.024 mol of platinum metal atoms), and the mixture was heated at 120°C for 8 hours to carry out a reaction. Next, 0.41 g of a 1% ethanol solution of L-proline (molar ratio of platinum catalyst:L-proline=1:1.5) was charged into the reactor, and after stirring at room temperature for 1 hour, the solvent was distilled off by heating under reduced pressure. Isododecane was added to adjust the concentration to 30%, and then the mixture was filtered to obtain an isododecane solution of a crosslinked organosilicon resin.

[0171] Furthermore, when the resulting crosslinked organosilicon resin solution in isododecane was heated to 120-130°C under reduced pressure and the isododecane was removed, the resulting product was a solid powder (weight average molecular weight 175,000, solvent: toluene). The conversion of alkenyl groups was 91%, and the amount of hydrogen gas generated from the remaining hydrosilyl groups was 0.9 mL / g. Formula (E1): Formula (E2):

[0172] Example 12 Method for producing a 30% solution of crosslinked organosilicon resin containing L-proline / methyl trimethicone 1,000 g of a 50% methyl trimethicone solution of a powdery alkenyl group-containing organosilicon resin (weight average molecular weight 7,430, vinyl value: 0.229 mmol / g) represented by the average composition formula (E1) below, 700 g of methyl trimethicone, 126.9 g of an organopolysiloxane having hydrosilyl groups at both ends represented by the formula (E2) below (amount of hydrogen gas generated: 20.3 mL / g, hydrosilyl group / vinyl group=1.0), and 3.0 g of a 0.3% ethanol solution of platinum-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex (equivalent to 0.024 mol of platinum metal atoms) were charged into a reactor and reacted by heating at 120°C for 8 hours. Next, 0.41 g of a 1% ethanol solution of L-proline (molar ratio of platinum catalyst:L-proline=1:1.5) was charged into the reactor, and after stirring at room temperature for 1 hour, the solvent was distilled off by heating under reduced pressure. Methyl trimethicone was added to adjust the concentration to 30%, and the mixture was then filtered to obtain a methyl trimethicone solution of a crosslinked organosilicon resin.

[0173] Furthermore, the resulting methyl trimethicone solution of the crosslinked organosilicon resin was heated to 120-130°C under reduced pressure to remove the methyl trimethicone, leaving a solid powder (weight average molecular weight 225,000, solvent: toluene). The conversion of alkenyl groups was 93%, and the amount of hydrogen gas generated from the remaining hydrosilyl groups was 0.7 mL / g. Formula (E1): Formula (E2):

[0176] <Preparation of Cosmetics> A: Components 1 to 7 were mixed uniformly. B: Components 8 to 13 were dispersed using a triple roll. C: Components 17 to 21 were mixed uniformly. D: The mixture obtained in C was added to the mixture obtained in A and emulsified, and B and components 14, 15, and 16 were added to obtain an emulsion cream foundation. E: The obtained emulsion cream foundation was stored in a constant temperature oven at 50°C for 6 months and then evaluated as follows.

[0177] [Feeling when used (sticky feeling)] Ten female expert panelists evaluated the "sticky feeling" of the obtained emulsion cream foundations according to the following criteria, and the average of the evaluation results was calculated. Based on the obtained average scores, a judgment was made according to the following criteria. The results immediately after preparation are shown in Table 8 below, and the results after 6 months of storage in a thermostatic chamber at 50°C are shown in Table 9 below. [Evaluation criteria] 5 points: very good 4 points: good 3 points: average 2 points: somewhat poor 1 point: poor [Judgment criteria] ◎: average score is 4.0 points or more ○: average score is 3.0 points or more and less than 4.0 points △: average score is 2.0 points or more and less than 3.0 points ×: average score is less than 2.0 points

[0178] [Elongation (Spreadability)] Dynamic friction of the obtained emulsion cream foundation was measured using a Trinity Lab TL201Tt and compared with a blank and evaluated according to the following criteria: ◎: Less than 105% ○: 105% or more but less than 110% △: 110% or more but less than 115% ×: 115% or more

[0179] [Secondary adhesion prevention] The same amount of the obtained emulsion cream foundation was applied to synthetic leather and dried at 50°C for 3 hours. After that, filter paper was placed on top and a 500g load was applied to compare the transfer to the filter paper and evaluated according to the following criteria: ◎: Almost no transfer ○: Slight transfer △: Transferred ×: Considerable transfer A rating of "○" or higher was considered to be acceptable.

[0180]

[0181] As shown in Table 8 above, the cosmetic compositions of the present invention were significantly superior to those of Comparative Examples 3 to 5 in terms of feel during use, spreadability, and prevention of secondary adhesion.

[0182]

[0183] As shown in Table 9 above, the cosmetic of the present invention was remarkably excellent in terms of usability, spreadability, and secondary adhesion prevention even after storage at 50°C. Therefore, the stability of the cosmetic was good. On the other hand, Comparative Example 5, in which the amino acid was added separately to the cosmetic, showed a decrease in spreadability and secondary adhesion prevention after storage at 50°C. This is thought to be because adding the amino acid separately to the cosmetic rather than blending it with the solution of the present invention does not provide the desired effect as an inactivator of the platinum catalyst.

[0184] Examples of cosmetics are shown below. The following were evaluated using the same criteria as above. [Example 14] Non-aqueous foundation <Preparation of cosmetic> A: Components 1 to 11 were mixed uniformly. B: Components 12 to 15 were mixed uniformly using a homomixer.
