The present invention relates to a cosmetic.
Conventionally, silicone resin has film-formation ability and is excellent in water resistance, perspiration resistance, and sebum resistance, and is therefore used as a raw material for cosmetics such as make-up cosmetics including foundation, lipstick, eye shadow, mascara, etc., ultraviolet protection cosmetics, and hair cosmetics. For example, the following are known: a skin cosmetic containing an organic silicone resin composed of units having an average formula of RnSiO4-n/2 and a volatile hydrocarbon oil (Patent Document 1); a skin cosmetic containing a resin composed of an R3SiO1/2 unit and an SiO4/2 unit and a volatile silicone oil (Patent Document 2); a sunscreen cosmetic containing a silicone resin having two or more kinds of an R2SiO2/2 unit, an RSiO3/2 unit, and an SiO4/2 unit and optionally having the terminals blocked with R3SiO1/2 units, a volatile oil agent, and an ultraviolet absorber and/or ultraviolet scattering agent (Patent Document 3); a skin cosmetic containing 1 to 70 mass % of an organic silicone resin, 70 mol % or more of the organic silicone resin consisting of an R3SiO1/2 unit and an SiO4/2 unit, and the molar ratio of an R3SiO1/2 unit to an SiO4/2 unit being from 0.5/1 to 1.5/1 (Patent Document 4); and so forth. These disclose that a film excellent in water resistance can be obtained, but do not disclose details regarding stiffness or feel of the film owing to the composition of the silicone resin.
In these known techniques, an SiO4/2 unit is contained, so that there is a problem that a stretched feeling is often given due to the stiffness of the film. Accordingly, to improve stiffness and brittleness of the film, the following are proposed: a cosmetic containing a silicone resin composed of 50 to 99 mol % of an RSiO3/2 unit and 1 to 50 mol of an R3SiO1/2 unit (Patent Document 5); a cosmetic containing a silicone resin, the molar ratio of (A) an R3SiO1/2 unit to (B) an RSiO3/2 unit being 1:4.7 to 1:7, and the silicone resin having a softening point of 50 to 110° C. and a weight-average molecular weight of 8000 to 400000 (Patent Document 6).
In these proposals, the crosslinking components of the silicone resin are constituted solely of RSiO3/2 units, and therefore, there are few crosslinking points. Accordingly, in order to improve water resistance, perspiration resistance, resistance to friction, and so forth more than before, the weight-average molecular weight needs to be 8000 or more. Moreover, since silanol groups remaining in the silicone resin exhibit thermosetting properties due to heating at a high temperature over a long period, the cosmetics are manufactured in a two-stage process including blocking with R3SiCl or the like in order to reduce the silanol groups.
In Patent Document 7, a cosmetic excellent in cosmetic durability and secondary adhesion is obtained by blending a silicone resin, the molar ratio of an RSiO3/2 unit and an SiO4/2 unit being 0.8:1.0 to 2.5:1.0, and the silicone resin having a weight-average molecular weight of 1500 to 20000. However, silicone resin has high compatibility with hydrocarbon oil, ester oil, triglyceride, etc., which are components of sebum, and physical strength of a cosmetic film is degraded over time, so that cosmetic durability is degraded. Therefore, further improvement of cosmetic durability is required. Furthermore, since more RSiO3/2 units are contained compared with a resin containing R3SiO1/2 units and SiO4/2 units in the same molecular weight, strength of a film is low, and issues are found in abrasion resistance.

The silicone resin (I) has a weight-average molecular weight of more than 20000 and 100000 or less. The weight-average molecular weight is more preferably more than 20000 and 50000 or less. This silicone resin (I) is capable of forming a film having no stickiness. In particular, the silicone resin (I) contains tetrafunctional SiO4/2 units in a composition within a specific range, so that a film having no stickiness can be formed, and stability over time, water resistance, and so forth are favorable. In addition a film having excellent abrasion resistance can be obtained compared with a silicone resin having a weight-average molecular weight of 20000 or less. Accordingly, the inventive cosmetic, containing this silicone resin, has no stickiness upon application, has smooth spreadability, excellent feeling on use, good water resistance, and excellent cosmetic durability owing to good adhesion to skin, can prevent adhesion to clothes or the like (secondary adhesion), and has excellent abrasion resistance. Note that the weight-average molecular weight can be determined as a weight-average molecular weight in terms of polystyrene in a gel permeation chromatography (GPC) analysis.
The silicone resin (I) is usually solid, and therefore, may be a ground solid, or may be a solution diluted with an oil agent that can be used in cosmetics.
The silicone resin (I) can be manufactured by a known method. That is, the silicone resin (I) can be manufactured by performing a hydrolysis condensation reaction between organosilicon compounds shown by the following general formulae (1) and (2) and compounds shown by the following formula (3), the following formula (4), and the following formula (5). Note that regarding the compounds shown by the following formulae (3) to (5), partial hydrolysis products thereof may be used instead of the compounds, or partial hydrolysis products thereof may be used in addition to the compounds.

R13SiOR4 (2)
R22Si(OR4)2 (3)
R3Si(OR4)3 (4)
Si(OR4)4 (5)
R1, R2, and R3 are as defined above, and R4 represents either a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
This hydrolysis condensation reaction is preferably performed under acidic condition, and an acidic substance is added as a catalyst. Examples of the acidic substance include hydrochloric acid, sulfuric acid, p-toluenesulfonic acid, methanesulfonic acid, trifluoromethanesulfonic acid, phosphoric acid, acetic acid, citric acid, etc. The amount of the acidic substance to be used may be a small amount, and is preferably 0.001 to 10 mass %, of the entire system.
In addition, a solvent can be used when performing the hydrolysis condensation reaction. Examples of the solvent include hydrocarbon-based solvents such as toluene, xylene, and isoparaffin, ether-based solvents such as tetrahydrofuran, and alcohol-based solvents such as methanol, ethanol, (iso)propyl alcohol, and butanol.

The temperature when dropping the water is preferably 0 to 80° C., particularly preferably 0 to 50° C., and the amount of the water to be dropped in is preferably within the range of 0.6 to 2.0 by molar ratio relative to the hydrolysable group. After dropping the water in, the mixture is heated at 50 to 150° C., preferably 80 to 120° C. for 2 to 8 hours to perform a hydrolysis condensation reaction. After the hydrolysis, acid is removed. To remove the acid, it is possible to employ a method of neutralization with alkali metal carbonate, alkali metal hydrogencarbonate, alkali metal hydroxide, etc. The acid may also be removed in a step of washing with water. After neutralizing the acid, an oil agent that can be used in cosmetics is added, and only the generated alcohols and excess water are removed by heating under normal pressure or reduced pressure. Thus, a silicone resin solution can be obtained. In addition, the oil agent that can be used in cosmetics may also be added during the hydrolysis condensation reaction.

After that, 400 g of decamethylcyclopentasiloxane was added thereto, and the mixture was heated to 130° C. to remove the generated ethanol and excess water and then cooled. Furthermore, after distillation under reduced pressure, the solution was diluted with decamethylcyclopentasiloxane, and then filtered. Thus, a 50% solution of silicone resin in decamethylcyclopentasiloxane was obtained, the silicone resin having a weight-average molecular weight of 9350, and the molar ratio of (CH3)3SiO1/2 unit:CH3SiO3/2 unit:SiO4/2 unit being 0.32:0.40:0.28.

Thus, a 50% solution of silicone resin in decamethylcyclopentasiloxane was obtained, the silicone resin having a weight-average molecular weight of 25500, and the molar ratio of (CH3)3SiO1/2 unit:CH3SiO3/2 unit:SiO4/2 unit being 0.28:0.55:0.17.
Except that the raw materials were changed to 150 g of hexamethyldisiloxane, 154 g of triethoxymethylsilane, and 480 g of ethyl polysilicate containing 40% of an SiO2 component, the 600 g of decamethylcyclopentasiloxane was changed to 300 g of isododecane, and that the diluent used after the distillation under reduced pressure was changed to isododecane, the same operation as Comparative Synthesis Example 1 was carried out. Thus, a 50% solution of silicone resin in isododecane was obtained, the silicone resin having a weight-average molecular weight of 24000, and the molar ratio of (CH3)3SiO1/2 unit:CH3SiO3/2 unit:SiO4/2 unit being 0.31:0.15:0.54.
Except that the raw materials were changed to 120 g of hexamethyldisiloxane and 791 g of triethoxymethylsilane, the same operation as Comparative Synthesis Example 1 was carried out. Thus, a 50% solution of silicone resin in decamethylcyclopentasiloxane was obtained, the silicone resin having a weight-average molecular weight of 3190, and the molar ratio of (CH3)3SiO1/2 unit:CH3SiO3/2 unit being 0.25:0.75.
Except that the raw materials were changed to 150 g of hexamethyldisiloxane and 420 g of ethyl polysilicate containing 40% of an SiO2 component, the 400 g of decamethylcyclopentasiloxane was changed to 300 g of isododecane, and that the diluent used after the distillation under reduced pressure was changed to isododecane, the same operation as Comparative Synthesis Example 1 was carried out. Thus, a 50% solution of silicone resin in isododecane was obtained, the silicone resin having a weight-average molecular weight of 5220, and the molar ratio of (CH3)3SiO1/2 unit:SiO4/2 unit being 0.40:0.60.
Except that the raw materials were changed to 120 g of hexamethyldisiloxane, 264 g of triethoxymethylsilane, and 148 g of ethyl polysilicate containing 40% of an SiO2 component, the same operation as Comparative Synthesis Example 1 was carried out. Thus, a 50, solution of silicone resin in decamethylcyclopentasiloxane was obtained, the silicone resin having a weight-average molecular weight of 19500, and the molar ratio of (CH3)3SiO1/2 unit:CH3SiO3/2 unit:SiO4/2 unit being 0.38:0.38:0.24.
The weight-average molecular weight and units of each silicone resin obtained in Synthesis Examples 1 to 10 and Comparative Synthesis Examples 1 to 7 were as shown in the Table 1 below. In addition, the R3SiO1/2 unit, the R2SiO2/2 unit, the RSiO3/2 unit, and the SiO4/2 unit were respectively denoted as described below. R3SiO1/2 unit→M, R2SiO2/2 unit→D, RSiO3/2 unit→T, and SiO4/2 unit→Q
Note that each of the M/D/T/Q in the Table respectively corresponds to the value of “a”, “b”, “c”, and “d” of the general formulae (A) to (D), M/(T+Q) corresponds to a/(c+d), and T/Q corresponds to c/d.
The solvent of the solution of silicone resin obtained in the Synthesis Examples and Comparative Synthesis Examples were distilled off, and a film was formed. Then, appearance, stickiness, and brittleness due to friction were evaluated. Table 2 shows the results.
In each of Synthesis Examples 1 to 10, a cracked film was obtained, and there was no stickiness. In each of Comparative Synthesis Examples 1 and 2, the molecular weight was low, and a uniform continuous film having no stickiness was obtained. In Comparative Synthesis Example 3, a sticky uniform continuous film was obtained since many T units were contained. In Comparative Synthesis Example 4, many Q units were contained, but as in Synthesis Examples 1 to 10, a cracked film was obtained, and there was no stickiness. In Comparative Synthesis Example 5, a film was not formed, and a highly viscous liquid was obtained since no Q units were contained, and the silicone resin was composed of M units and T units. In Comparative Synthesis Example 6, as in Synthesis Examples 1 to 10, a cracked film was obtained, and there was no stickiness since no T units were contained, and the silicone resin was composed of M units and Q units. In Comparative Synthesis Example 7, as in Synthesis Examples 1 to 10, a cracked film was obtained, and there was no stickiness, but the weight-average molecular weight was outside the range of the present invention.
The silicone resin to be contained in the inventive cosmetic gives a hard, brittle film on its own as described above. However, as described below, a cosmetic containing this silicone resin can be a cosmetic that has no stickiness upon application, has smooth spreadability, excellent feeling on use, good water resistance, and excellent cosmetic durability owing to good adhesion to skin, can prevent adhesion to clothes or the like (secondary adhesion), and has excellent abrasion resistance.

The components (12) to (15), the remainder of the component (5), and the component (25) were added to the emulsion and mixed. The mixture was loaded into a prescribed container to prepare an emulsion cream foundation. The following evaluations were conducted on the resulting emulsion cream foundations.
Spreading at the time of application (spreadability), sticky feeling, finished color unevenness, cosmetic durability (durability (evaluation 8 hours after application)), and secondary adhesion of the resulting emulsion cream foundations were evaluated by 50 female expert panelists according to the following criteria and the evaluation results were averaged.
The emulsion cream foundations were applied to the foreheads of the expert panelists respectively by the same operation, and at 20 minutes after the application, tissue paper was pressed against the applied part, and the secondary adhesion prevention effect of the cosmetic was evaluated according to the criteria of the following Table 4. The average of the evaluation results was taken.
On the basis of the average points of the obtained evaluation results, the results are shown in Table 5 based on the following.
⊚⊚: Excellent: the average point is 4.5 points or more
⊚: Good: the average point is 4.0 points or more and less than 4.5 points

In addition, the inventive cosmetics were significantly superior to Comparative Example 2 regarding spreadability, color unevenness, and secondary adhesion prevention, since the amount of T units contained in the film was large. Furthermore, the inventive cosmetics were significantly superior to Comparative Example 3 regarding spreadability, sticky feeling, color unevenness, cosmetic durability, and secondary adhesion prevention, since the molecular weight of the film was high and T units were contained.
