Abstract
Description
Technical Field
[0001] The present invention relates to a cosmetic containing a cross-linked silicone resin and a method for producing the same. Background Art
[0002] Silicone resins can improve the durability of cosmetics by being mixed with them. However, there are two problems with mixing silicone resins with cosmetics. The first problem is that the film formed is brittle. The film formed by applying cosmetics containing silicone resins to hair, face, hands, etc., breaks or peels off due to slight movements, and thus lacks followability. In particular, the M unit (R 3 SiO 1 / 2 ) and Q unit (SiO 4 / 2 ) is very strong, so it has good mechanical strength, but it is difficult to form a self-supporting film because the film is brittle. On the other hand, MTQ, MDQ, MDTQ and DT resins introduced with T units and D units have improved film flexibility compared to MQ resins, and can form a strong self-supporting film with followability. However, the strength from the resin remains, which has problems in abrasion resistance. Patent document 1 discloses that a crack-free film can be formed by applying an emulsion containing a plasticized MQ resin to a hair cosmetic. However, when a silicone rubber is added as a plasticizer, the film strength is reduced and the adhesiveness is increased, which gives an unpleasant feeling such as a sticky feeling, and the feeling of use is deteriorated.
[0003] The second problem 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 oil, ester oil, triglyceride, etc. The silicone resin used as a film-forming agent has high compatibility with these oils. Therefore, after the cosmetic is applied, the film swells over time, and there is also a problem that the physical strength of the cosmetic film is reduced and the durability of the makeup is deteriorated. On the other hand, in Patent Document 2, a highly oil-resistant composition using a silicone resin and a silicone-modified acrylic polymer is proposed. Since the silicone-modified acrylic polymer forms a soft film, it can impart some softness and followability, but it cannot obtain sufficient oil resistance and has no effect on improving the durability of the makeup.
[0004] In recent years, a cross-linked silicone resin in which a silicone resin is cross-linked with silicone has been reported. In Patent Document 3, it is reported that a silicone resin containing vinyl groups and silicone containing hydrosilyl groups are heated to produce a cross-linked silicone resin, and a cured product with high flexibility is obtained. However, since it is difficult to dissolve in volatile oils, it is difficult to use as a film-forming agent. The same cross-linked silicone resin is also reported in Patent Documents 4 and 5, but since it is a gel in nature, it does not have the ability to form a film. In Patent Document 6, a silicone resin containing hydrosilyl groups and silicone containing vinyl groups are cross-linked by heat curing to form a cross-linked silicone resin. However, the cured product obtained is sticky and has low solubility in volatile oils. In Patent Document 7, a silicone resin containing hydrosilyl groups and a silicone containing vinyl groups whose reaction points are limited are reacted to form a cross-linked silicone resin soluble in volatile oils. However, the reactivity of the hydrosilyl groups is low, and the remaining hydrosilyl groups react over time, resulting in an increase in viscosity and the generation of hydrogen, making it difficult to use. In Patent Document 8, an organopolysiloxane gel is prepared by crosslinking an organosilicone resin having an unsaturated group with an organohydrogenpolysiloxane having 30 or more D units. However, if the chain length of the crosslinking agent is long, a solvent is inserted into the network, and the property tends to become gel-like, resulting in a sticky film.

[0015] Problems to be solved by the invention
[0016] The present invention has been completed in view of the above-mentioned actual situation, and its purpose is to provide a cross-linked silicone resin that has excellent stability over time and forms a coating that is excellent in oil resistance, non-sticky, non-brittle, and highly flexible; a cosmetic material that is blended with the cross-linked silicone resin, has a good feel in use, good elongation, and excellent anti-secondary adhesion; and a method for manufacturing the same.
[0017] Means for solving problems
[0018] The present inventors have conducted intensive studies to achieve the above-mentioned purpose, and as a result, have found that, compared with silicone resins containing hydrosilyl groups, silicone resins containing alkenyl groups have high reactivity of alkenyl groups, and can reduce the amount of unreacted functional groups. Also, by controlling the ratio of the amount of hydrosilyl groups to the amount of alkenyl groups, the amount of residual hydrosilyl groups can be reduced, thereby suppressing the increase in viscosity over time and the generation of hydrogen gas.
[0019] Furthermore, the alkenyl group content of the alkenyl group-containing silicone resin and the chain length of the organohydrogenpolysiloxane were determined, and it was found that the cross-linked silicone resin obtained in this way can form a soft coating film that is not sticky and has high flexibility.
[0020] Generally, it is said that hard coatings tend to have low flexibility, and coatings with high flexibility tend to be soft, and there is a paradoxical relationship between the strength and flexibility of the coating. However, although the cross-linked silicone resin of the present invention forms a firm coating, it has high flexibility and therefore excellent followability. Furthermore, the oil resistance to oil agents such as sebum is greatly improved compared to before modification. As the molecular weight of the silicone resin increases, the oil resistance tends to increase, but there is a limit to increasing the molecular weight of the silicone resin, so the oil resistance also has a limit point. The cross-linking of the silicone resin produced by the cross-linking agent may lead to an increase in the molecular weight of the silicone resin, so it has the effect of increasing its limit point. Therefore, the cross-linked silicone resin has oil resistance that cannot be achieved for existing silicone resins. In addition, by being mixed in the cosmetic as a coating forming agent, it becomes a cosmetic that is not sticky when applied and has a good sense of use. In addition, due to the good adhesion to the skin, a cosmetic with excellent abrasion resistance such as good elongation and the effect of preventing secondary adhesion is obtained.

[0064] [(B) ingredient]
[0065] The component (B) of the present invention is an organohydrogenpolysiloxane represented by the following average composition formula (2) and having two or more hydrosilyl groups in one molecule, and one type thereof can be used alone or in combination of two or more types thereof. The addition reaction amount is such that the amount of hydrosilyl groups becomes 0.5 to 1.2 mol relative to 1 mol of the alkenyl groups in the component (A), preferably 0.5 to 1.2 mol, more preferably 0.8 to 1.2 mol, and still more preferably 0.9 to 1.1 mol.
[0066] [Chemistry 7]
[0067] (R 4 3SiO 1 / 2 ) e (R 4 2SiO 2 / 2 ) f (R 2 SiO 3 / 2 ) g (SiO 4 / 2 )h (2)
[0068] [Where R 2 Same as above, R 4 are independently a hydrogen atom or the above R 2 The groups represented by all R 4 Two or more of them are hydrogen atoms, and e, f, g, and h are 0 or positive numbers, but 2≤e+f+g+h<32. ]
[0069] In the above formula, R 1 Each of them is independently an alkenyl group having 2 to 8 carbon atoms. More specifically, vinyl, allyl, isopropenyl, butenyl, pentenyl, hexenyl, cyclohexenyl, octenyl, etc. are exemplified. Vinyl and allyl are particularly preferred.
[0070] In the above formula, R2 are independently selected from an alkyl group having 1 to 30 carbon atoms, an aryl group having 6 to 30 carbon atoms, or an aralkyl group having 7 to 30 carbon atoms. Among them, an alkyl group, an aryl group, an aralkyl group, or a fluorine-substituted alkyl group having 1 to 10 carbon atoms is preferred. More specifically, methyl, ethyl, propyl, butyl, pentyl, cyclopentyl, cyclohexyl, phenyl, tolyl, trifluoropropyl, etc. are listed. An alkyl group having 1 to 5 carbon atoms, a phenyl group, or a trifluoropropyl group is particularly preferred. In addition, R 2 A part of may contain one or more groups selected from a hydroxyl group or an alkoxy group having 1 to 8 carbon atoms.
[0071] In the alkenyl-containing silicone resin represented by the above formula (1), a1, a2, a3, b, c and d are 0<a1≤5, preferably 0<a1≤4.5, more preferably 1≤a1≤4, and further preferably 1≤a1≤3. If a1 is larger than 5, the possibility of gelation increases and the film forming property is also poor. It is 0≤a2≤400, preferably 0≤a2≤100, and more preferably 0≤a2≤50. It is 0≤a3≤400, preferably 0≤a3≤100, and more preferably 0≤a3≤50. If a3 is larger than 400, the melting point of the resin decreases, so the film forming property is poor. It is 0≤b≤320, 0≤c≤320, preferably b=0, and c=0. The number is a number satisfying 0<d≤1000, 0.5≤(a1+a2+a3) / d≤1.5, preferably a number satisfying 0.7≤(a1+a2+a3) / d≤1.2. If the value of (a1+a2+a3) / d is less than the above lower limit, the degree of crosslinking increases, the molecular weight increases, and thus the gel is formed. If the above upper limit is exceeded, the molecular weight decreases, and thus the film forming property is poor.
[0072] The alkenyl-containing organic silicone resin represented by the above formula (1) has a Q unit (SiO 4 / 2 )、M unit (R 2 3SiO 1 / 2 and R 1 R 2 2SiO 1 / 2 ) is a necessary structure, with D unit (R 2 2SiO 2 / 2 )、T unit (R 2 SiO 3 / 2) is an optional structure. It can be solid or liquid at 25°C, and is preferably solid from the perspective of film forming properties. For example, MQ resin, MTQ resin, MDQ resin, and MDTQ resin can be listed. The weight average molecular weight is preferably in the range of 1000 to 30000, and is more preferably in the range of 3000 to 15000 in terms of performance and operability such as filtration. It should be noted that the weight average molecular weight can be obtained as a weight average molecular weight converted to polystyrene in gel permeation chromatography (GPC) analysis.
[0073] In the organohydrogenpolysiloxane represented by the above formula (2) having two or more hydrosilyl groups in one molecule, R 4 are independently a hydrogen atom or a monovalent hydrocarbon group having 1 to 30 carbon atoms and having no aliphatic unsaturated bond, and all R 4 Two or more of them are hydrogen atoms.
[0074] In the above formula (2), e, f, g, and h are 0 or positive numbers, and can be selected as long as they satisfy 2≤e+f+g+h<32. Preferably, g=0 and h=0, more preferably, e=2, 0≤f<30, g=0, and h=0, and further preferably, e=2, 0≤f≤20, g=0, and h=0. If the number of silicon atoms contained in component (B) is 32 or more, the cross-linked silicone resin embraces the solvent, and the property is likely to become a gel. Therefore, after the solvent evaporates, it is easy to become a sticky film. If the number of silicon atoms contained in component (B) is less than 32, the cross-linked silicone resin dissolves in the solvent, and the property is likely to become a liquid. Therefore, after the solvent evaporates, it is easy to obtain a non-sticky film.
[0075] The above R 3 are independently selected from a group containing an organopolysiloxane, or the above R 2 The group containing the organopolysiloxane includes, for example, groups represented by the following general formulae (3) to (6). 3 3SiO 1 / 2 In each unit, one or more R 3 is a group containing an organic polysiloxane. In addition, optionally, R 3 A portion of may be a hydroxyl group.

[0082] m is an integer of 0≤m≤5, preferably 0≤m≤2, and i is an integer of 0≤i≤500, preferably 1≤i≤100, more preferably 1≤i≤50. If i is greater than 500, the melting point of the resin decreases, thereby poorly forming a film. j1 to j3 are each an integer of 0 to 2.
[0083] In the above formula (1), preferably b=0 and c=0. When b and c are 0, the alkenyl-containing silicone resin does not contain a flexible skeleton such as a D unit or a T unit, and is composed only of an M unit and a Q unit. By using an alkenyl-containing silicone resin that does not contain a D unit or a T unit as a raw material, a cross-linked silicone resin as an addition reaction product can form a strong coating.
[0084] In the above formula (2), preferably g = 0 and h = 0. When g and h are 0, the organohydrogenpolysiloxane becomes a linear molecule consisting only of M units and D units without branching components such as T units and Q units. By using a linear organohydrogenpolysiloxane as a raw material, a cross-linked silicone resin as an addition reaction product can form a soft coating.
[0085] In addition, there may be two or more groups represented by formula (2). As the chain length of the group represented by formula (2) increases, it has the effect of imparting flexibility to the silicone resin. Therefore, for example, by including two groups represented by formula (2) having different chain lengths, the coating properties can be controlled.
[0086] [Physical properties of cross-linked silicone resin]
[0087] The weight average molecular weight of the cross-linked silicone resin of the present invention is preferably 5,000 to 1,000,000, more preferably 8,000 to 500,000, and further preferably 10,000 to 500,000. By being within such a range, it is more preferred in terms of performance and operability such as filtration. It should be noted that the weight average molecular weight can be obtained as a weight average molecular weight converted to polystyrene in gel permeation chromatography (GPC) analysis (the same below).
[0088] The cross-linked silicone resin can be solid, gel or liquid at 25°C. For example, by dissolving it in a liquid oil and volatilizing it, a coating can be easily formed. The coating is a brittle and strong coating before cross-linking, but its brittleness is improved after cross-linking, resulting in a non-sticky and soft coating. From the perspective of film formation, a solid or gel state is preferred, and a solid state is more preferred. The film forming ability can be determined by dropping 1.5 g of a dissolved product diluted with 30% by mass of isododecane or decamethylcyclopentasiloxane on PTFE (fluororesin), drying it at 105°C for 3 hours, and whether a self-supporting film is formed. In the case where a coating is not formed, oil seeps out from cracks in the coating, the oil resistance is significantly reduced, and the followability to the skin is low, resulting in an unnatural finish.
[0089] The cross-linked silicone resin of the present invention can be used more preferably as a film-forming agent. The silicone resin before cross-linking forms a strong film with brittleness. On the other hand, as for the cross-linked silicone resin after cross-linking, its brittleness is improved, and a non-sticky and soft film is formed. This is because the silicone resin before cross-linking forms a strong film, and the film is given softness by cross-linking with soft chains. In general, it is said that hard films have low flexibility, and films with high flexibility tend to be soft, so there is a paradoxical relationship between the strength and flexibility of the film. However, the cross-linked silicone resin of the present invention has the following characteristics: although a strong film is formed, it has high flexibility and therefore excellent followability.
[0090] In addition, the coating formed with the cross-linked silicone resin has a significantly improved oil resistance to oils such as sebum compared to the coating formed with the silicone resin before cross-linking. The oil resistance of silicone resin tends to improve as the molecular weight increases, but there is a limit to how much the molecular weight of silicone resin can be increased, so the oil resistance also has a limit point. The cross-linking of silicone resin by the cross-linking agent may increase the molecular weight of the silicone resin, which has the effect of raising its limit point. Therefore, the cross-linked silicone resin has oil resistance that cannot be achieved with existing silicone resins.
[0091] A cross-linked silicone resin in which f in the formula (2) is an integer satisfying 0<f<30 is solid at 25° C. and can provide a cross-linked silicone resin having particularly excellent film-forming properties.
[0092] In addition, f in the above formula (2) satisfies 0≤f<30, R 4 A cross-linked silicone resin in which two of the atoms are hydrogen atoms is solid at 25° C., and a cross-linked silicone resin having particularly excellent film-forming properties can be obtained. 4 When three or more of the atoms are hydrogen atoms, the possibility of becoming a gel when the diluting solvent is removed may increase. In this case, the film-forming property is maintained, but the feeling is that of a gel.
[0093] In the above formula (1), a1 is 0<a1≤3, f in the above formula (2) satisfies 0≤f<20, R 4 The crosslinked silicone resin in which two of the atoms are hydrogen atoms is solid at 25° C., and a crosslinked silicone resin having particularly excellent film-forming properties can be obtained. The obtained film exhibits particularly excellent flex resistance and oil resistance.
[0094] The amount of hydrogen per unit mass generated by the cross-linked silicone resin is 1.5 mL or less under standard conditions. If it exceeds 1.5 mL / g, the viscosity may increase over time due to hydrogen generation or reaction of the remaining hydroxyl group and alkoxy group with the hydrosilyl group, thereby deteriorating the stability over time. The amount of hydrogen generation is preferably 0.01 to 1.2 mL / g, and more preferably 0.02 to 1.0 mL / g.
[0095] The amount of hydrogen gas per unit mass can be calculated from the volume of hydrogen gas generated by the reaction of the hydrosilyl group and the base. For example, the following method can be used, but the calculation method is not limited to this.
[0096] <Method for measuring the amount of hydrogen>
[0097] 10 g of 20% by mass sodium hydroxide aqueous solution was added dropwise to a mixed solution of 50 g of a crosslinked silicone resin diluted to 50% by mass with decamethylcyclopentasiloxane and 10 g of 1-butanol. The volume of generated hydrogen gas was divided by the purity of the crosslinked silicone resin to determine the amount of hydrogen gas per unit mass.
[0098] [Manufacturing method]
[0099] Since it is difficult to completely control the amount of silanol groups on the surface of the silicone resin, it is difficult to control the amount of the cross-linked organopolysiloxane with high precision. In addition, the synthesis can be performed by an addition reaction of an organosilicone resin having a hydrosilyl group and an organopolysiloxane having alkenyl groups at both ends. However, the reactivity of the hydrosilyl groups in the silicone resin is low, and there are problems such as increased viscosity and generation of hydrogen due to the reaction of the remaining hydrosilyl groups over time. Therefore, as a method for manufacturing a cross-linked silicone resin cross-linked with silicone, it is preferred to use a synthesis method of an addition reaction of an organosilicone resin having alkenyl groups and an organopolysiloxane having hydrosilyl groups at both ends.
[0100] The method for producing a cross-linked silicone resin using the hydrosilylation reaction is described in detail below.
[0101] In the hydrosilylation reaction step of the alkenyl group-containing organosilicon resin represented by the above average composition formula (1) and the organohydrogenpolysiloxane represented by the above formula (2), the molar ratio of the terminal hydrosilyl group / unsaturated group can be selected from the range of 0.5 to 2.0, preferably 0.5 to 1.2 mol, more preferably 0.8 to 1.2, and further preferably 0.9 to 1.1. If the above ratio is too large, the residual amount of the hydrosilyl group increases, and the stability over time may deteriorate.
[0102] The hydrosilylation reaction is preferably carried out in the presence of a platinum catalyst or a rhodium catalyst. For example, preferably chloroplatinic acid, alcohol-modified chloroplatinic acid, chloroplatinic acid-vinylsiloxane complex, etc. In addition, with regard to the usage amount of the catalyst, if it is contained excessively, the sample is colored, so in terms of the amount of platinum or rhodium, preferably below 50ppm, more preferably below 20ppm.
[0103] Furthermore, the above addition reaction can be carried out in the presence of an organic solvent as required. As organic solvents, cyclic organopolysiloxanes such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane can be listed; aromatic hydrocarbons such as toluene and xylene; ketone organic solvents such as acetone, methyl ethyl ketone, diethyl ketone, and methyl isobutyl ketone; aliphatic hydrocarbons such as hexane, heptane, octane, and cyclohexane; 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 aliphatic alcohols such as 1,2-propylene glycol can be listed. In particular, from the viewpoint of reactivity, ethanol, 1-propanol, and 2-propanol are preferred.
[0104] 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 the above range, the solvent is uniformly maintained in the reaction system, and the reaction proceeds efficiently.
[0105] The addition reaction conditions are not particularly limited, but heating is preferably performed at 50 to 150° C., more preferably 80 to 120° C., under reflux for about 1 to 10 hours.
[0106] After the addition reaction, the step of removing the used rhodium catalyst or platinum catalyst with activated carbon may also be included. The amount of activated carbon used is preferably 0.001 to 5.0% by mass of the entire system, and more preferably 0.01 to 1.0% by mass. If it is within the above range, the coloring of the sample can be further suppressed.
[0107] After the addition reaction, a step of removing the remaining hydrosilyl group may be included as needed. In particular, when used in cosmetics, the hydrosilyl group may be deactivated by dehydrogenation reaction after a period of time. Since hydrogen gas is generated, there is a problem from the perspective of safety, so it is preferred to include a step of removing the hydrosilyl group.
[0108] As a process for removing the hydrosilyl group, a formula in which an acidic catalyst equal to the molar equivalent of the alkaline catalyst is added after the unreacted hydrosilyl group is hydrolyzed can be listed. As an alkaline catalyst, a strong alkaline catalyst and a weak alkaline catalyst can be listed. As examples of strong alkaline catalysts, alkali metal hydroxides such as lithium hydroxide, sodium hydroxide, potassium hydroxide, calcium hydroxide, and barium hydroxide can be listed. As examples of weak alkaline catalysts, alkali metal carbonates such as sodium carbonate and calcium carbonate, alkali metal bicarbonates such as sodium bicarbonate and potassium bicarbonate can be listed. In terms of promoting the dehydrogenation reaction, it is particularly preferred to use a strong alkaline catalyst, specifically, sodium hydroxide is preferred. As examples of acidic catalysts, inorganic acids such as hydrochloric acid, sulfuric acid, sulfurous acid, oleum, phosphoric acid, sulfonic acids such as p-toluenesulfonic acid, methanesulfonic acid, and trifluoromethanesulfonic acid, oxalic acid, formic acid, acetic acid, propionic acid, benzoic acid, citric acid, and trifluoroacetic acid can be listed.
[0109] In addition, generally, it is preferred to use an acid or a base in combination with water and to heat at a temperature below the boiling point of water rather than using the acid or the base alone. Through this process, the hydrosilyl group (SiH group) becomes a hydroxysilyl group (SiOH group). However, when a cross-linked silicone resin is treated with an alkali catalyst, the silanol group and the alkoxy group in the silicone resin react, thereby changing the physical properties. Therefore, it is not preferred to remove the hydrosilyl group by this method.
[0110] [Cosmetics]
[0111] By blending the cross-linked silicone resin of the present invention (hereinafter sometimes referred to as component (a)) into a cosmetic, the cross-linked silicone resin functions as a film-forming agent, does not feel sticky when applied, has an excellent feel during use, has good water resistance and oil resistance, and has good adhesion to the skin, thereby obtaining a cosmetic having good elongation, excellent finishing properties, water resistance and oil resistance, excellent makeup durability (sustainability), and excellent abrasion resistance such as an effect to prevent secondary adhesion.
[0112] In terms of the convenience of compounding the cross-linked silicone resin of the present invention in water-based and emulsified compositions, an O / W emulsion can be prepared to form an intermediate composition. That is, an O / W emulsion in which a dissolution product of any oil agent of the cross-linked silicone resin of the present invention is dispersed as a dispersed phase in an aqueous phase as a continuous phase becomes an intermediate composition. There is no particular limitation on the method for preparing the O / W emulsion, and it can be prepared by a known method. For example, a method of emulsifying using one or two or more active agents with an HLB of 10 or more can be cited, and as a stabilizer, an active agent with an HLB of less than 10, a higher alcohol, etc. can be used. In addition, carbomer, etc. can be used in the aqueous phase to increase the viscosity.
[0113] The content of the crosslinked silicone resin (a) of the present invention is preferably in the range of 0.1 to 40% by mass, more preferably in the range of 0.1 to 10% by mass, of the total cosmetic. If it is less than 0.1% by mass, sufficient oil resistance cannot be obtained, and if it is more than 40% by mass, the feeling of use may be deteriorated.
[0114] The cross-linked silicone resin of the present invention can also be dissolved in any solvent and provided as a dissolved product. When the solvent is a volatile oil agent having a boiling point of 250°C or less at 1013 hPa, a film can be formed by the volatilization of the solvent, and the effect as a film-forming agent can be further manifested. As the volatile oil agent having a boiling point of 250°C or less at 1013 hPa, it is preferably selected from one or more of silicone oil, isododecane and ethanol, and one or more of them can be used alone or in combination.
[0115] (b) Volatile oil
[0116] As the volatile oil agent, it is preferred that a film is formed early after the application of the cosmetic material to show its effect, and from this point of view, it is preferred to mix a volatile oil agent with a boiling point of 250° C. or less.

In addition, lower alcohols such as ethanol (INCI: Alcohol) and isopropyl alcohol (INCI: Isopropyl Alcohol), and acetates such as ethyl acetate (INCI: Ethyl Acetate) and butyl acetate (INCI: Butyl Acetate) can be listed. These volatile oils can be appropriately selected and combined according to the type of the base of the cosmetic. For example, when the base is a silicone-based base, it is appropriate to select silicone oil in order to improve the compatibility of the entire cosmetic composition. If the base is silicone oil, a good feeling is obtained, so it is preferred, and commercially available products include TMF-1.5, KF-995, KF-96L-1cs, KF-96L-1.5cs, KF-96L-2cs, KF-4422, etc. manufactured by Shin-Etsu Chemical Co., Ltd. The amount of the volatile oil (B) is preferably in the range of 0.1 to 70% by mass, more preferably in the range of 0.1 to 20% by mass, of the total cosmetic or dissolved product. If it is less than 0.1% by mass, solubility may be lacking, and if it is more than 70% by mass, a dry feeling may be felt.

[0432] <Temporal stability>
[0433] The decamethylcyclopentasiloxane solutions of the crosslinked silicone resin obtained in the above Examples and Comparative Examples were stored in a thermostat at 50° C., and the viscosity was measured after 2 weeks and one month, and evaluated according to the following criteria. The results are shown in Table 1.
[0434] ◎: The difference between the viscosity value immediately after production and the viscosity value after storage at 50°C is less than 5%
[0435] ○: The difference between the viscosity value immediately after production and the viscosity value after storage at 50°C is 5% or more and less than 10%
[0436] ×: The difference between the viscosity value immediately after production and the viscosity value after storage at 50°C is 10% or more

[0439] For Examples 1 to 15, the difference between the viscosity value just after manufacture and the viscosity value after 2 weeks and 1 month is less than 5%, and the stability after time is good. It is believed that the alkenyl group in the silicone resin has high reactivity and the amount of residual hydrosilyl groups is small, so the reaction after time is suppressed as the main reason. Comparative Example 1 is a solution of a cross-linked silicone resin using a silicone resin containing a hydrosilyl group as a raw material. It is believed that since the reactivity is low compared to the alkenyl group and the amount of residual hydrosilyl groups is large, the slow reaction after time is the main reason for the increase in viscosity. Comparative Example 2 is a solution of a cross-linked silicone resin using a silicone resin containing a hydrosilyl group as a raw material and subjected to an alkali treatment. It is believed that the residual hydrosilyl groups in the silicone resin cannot be completely inactivated even with an alkali treatment, and the slow reaction after time is the main reason for the increase in viscosity. Furthermore, it is believed that the main reason is that the pH is biased towards alkalinity compared to Comparative Example 1, and the rate of increase in viscosity is accelerated.
[0440] The shape at 25° C., film-forming ability, and physical properties (continuity, hardness, and bendability) of each silicone resin obtained in the above Examples and Comparative Examples were evaluated as follows. The results are shown in Table 2 below.
[0441] 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 silicone resin, and the shape at 25° C. was observed.
[0442] 2) Regarding the film forming ability, 1.5 g of a 30% solution diluted with a solvent (isododecane or decamethylcyclopentasiloxane) was dropped into a PTFE (fluororesin) container and then dried at 105°C for 3 hours to evaluate whether a self-standing film was formed.
[0443] 3) Regarding the continuity of the film, whether the film produced in 2) above was a continuous film (that is, whether there were cracks) was evaluated. The film without cracks was evaluated as "having continuity".
[0444] 4) Regarding the hardness of the coating, whether or not a nail could penetrate into the coating produced in the above 2) was evaluated. The coating that could be penetrated by a nail was recorded as "soft".
[0445] 5) Regarding the stickiness of the film, the stickiness of the film produced in the above 2) was evaluated as "absent" or "present".
[0446] 6) Regarding bendability, whether the coating formed by the method 2) above bends when it is bent on an aluminum dish was evaluated. If the coating is cracked, the bendability is recorded as "None".
[0447] [Table 2]

[0449] Examples 1 to 15 all obtained uniform continuous films, which were non-sticky and non-brittle films. In addition, they were films with high bendability when bent. Comparative Example 3 reacted an alkenyl-rich silicone resin with an organohydrogenpolysiloxane, resulting in a high crosslinking density and a gel, without obtaining film formation properties. Comparative Examples 4 and 5 were films composed of a crosslinked silicone resin crosslinked with an organohydrogenpolysiloxane with a long chain length. They were both continuous, soft films, and were in the form of raw rubber, so they were highly sticky. Comparative Examples 6 and 7 were films composed of a non-crosslinked silicone resin composed of M units and Q units. They were non-sticky but cracked hard films, and the films could be easily cracked by bending. From the above, it can be seen that the crosslinked silicone resin of the present invention has greatly improved bending and stickiness properties compared to existing non-crosslinked silicone resins.
[0450] 3 μL of squalane, oleic acid, and triisooctanoin were dropped into each of the films obtained in Examples 1 to 15 and Comparative Examples 6 and 7, and the contact angles were measured. The results are shown in Table 3 below.
[0451] [Table 3]
[0452]
[0453] In Examples 1 to 15, the contact angles for all oils including squalane, oleic acid, and triethylhexanoin were large, indicating high oil resistance. On the other hand, in Comparative Examples 6 and 7, the contact angles for all oils were low, indicating low oil resistance. The oil resistance of non-crosslinked silicone resins tends to improve as the molecular weight increases, but since the molecular weight increase of non-crosslinked silicone resins is limited, the oil resistance also has a limit. The crosslinking of the silicone resin by the crosslinking agent may cause the molecular weight of the silicone resin to increase, and thus has the effect of increasing its limit. Therefore, the crosslinked silicone resin of the present invention can have oil resistance that conventional non-crosslinked silicone resins cannot achieve.
[0454] The solid powder obtained in Example 3 was mixed with isododecane, methyl trimethyl polysiloxane, dimethyl polysiloxane (KF-96-2cs and 6cs), triethylhexanoin, and isotridecyl isononanoate at a solid content concentration of 50%, and a solubility test was performed. The results are shown in Table 4 below.
[0455] ○: Transparent dissolution
[0456] △: Slightly turbid
[0457] ×: Separated.

[0460] Furthermore, the obtained polymer can also be dissolved in silicone and ester oils used in cosmetics other than the above-mentioned oils. In addition, the viscosity of these solutions can vary depending on the composition and molecular weight of the polymer.
