Description

[Technical Field]

[0001] This invention relates to organopolysiloxanes and cosmetics using the same. [Background technology]

[0002] Silicone-based surfactants are widely used because they provide a refreshing, non-greasy feel and excellent usability. For example, numerous emulsifying compositions containing polyether-modified silicones or polyglycerin-modified silicones have been proposed (Patent Documents 1 and 2). However, when polar oils such as ester oils are used as the oiling agent, the emulsification stability is insufficient, and phase separation can occur over time.

[0003] Furthermore, Patent Document 3 proposes the use of carboxyl-modified silicone in oil-in-water emulsion compositions. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2021-075488 [Patent Document 2] International Publication No. 2018 / 117172 [Patent Document 3] Japanese Patent Publication No. 2020-172481 [Overview of the project] [Problems that the invention aims to solve]

[0005] However, there is still room for improvement in the emulsification stability performance of silicone-based surfactants, as the use of fine-particle zinc oxide in combination can sometimes worsen emulsification stability. Therefore, increasing the amount of emulsifiers and thickeners to improve emulsion stability resulted in increased stickiness, which worsened the pleasant feel that is a key advantage of silicone-based surfactants.

[0006] The present invention has been made in view of the above circumstances, and aims to provide an organopolysiloxane having excellent emulsification stability, and a cosmetic composition using the organopolysiloxane. [Means for solving the problem]

[0007] As a result of diligent research to achieve the above objective, the inventors of the present invention discovered that using an organopolysiloxane having both a (poly)glycerin group or a polyoxyalkylene group and a carboxyl group as an emulsifier results in an emulsified composition with extremely excellent storage stability, leading to the present invention.

[0008] In other words, the present invention provides a carboxyl group-modified organopolysiloxane having a (poly)glycerin group or a polyoxyalkylene group as shown below, and cosmetics using this organopolysiloxane.

[0038] The hydrosilylation reaction can be carried out using known methods. The composition in formula (1) can be adjusted by changing the raw materials used and their proportions. For example, organohydrogenpolysiloxane (H), compounds represented by formulas (ii) and (iii), and optionally compounds represented by formulas (iv) and (v) can be added to the reactor in the desired molar ratio, and then a platinum catalyst can be added to carry out the reaction. The order in which the compounds represented by formulas (ii), (iii), (iv), and (v) are added is not particularly limited, but for example, they can be added in the order of formulas (iv), (ii), (v), and (iii). Examples of platinum catalysts are not particularly limited, but include PtCl4, H2PtCl6·6H2O, Pt-ether complexes, Pt-olefin complexes, PdCl2(PPh3)2, PdCl2(PhCN)2, RhCl2(PPh3)3 (wherein Ph is a phenyl group), platinum chloride, chloroplatinic acid or chloroplatinate, and complexes of vinyl group-containing siloxanes. These catalysts may be used individually or as a mixture of two or more. Among these, Karstedt catalysts are particularly preferred (a complex of 1,1,3,3-tetramethyl-1,3-divinyldisiloxane and a sodium bicarbonate neutralized product of chloroplatinic acid). The amount of platinum catalyst is not particularly limited and should be a catalytic amount. The catalytic amount is an amount sufficient to carry out the hydrosilylation reaction, for example, per 100 parts by mass of the organohydrogenpolysiloxane (H), the amount of platinum catalyst in terms of platinum metal atoms is preferably 0.02 parts by mass or less, more preferably 0.00001 to 0.02 parts by mass, even more preferably 0.0001 to 0.01 parts by mass, and particularly preferably 0.0003 to 0.005 parts by mass.

While there are no particular limitations on the solvent, examples include isopropyl alcohol, tetrahydrofuran, and toluene. If the compound represented by formula (ii) is one in which the carboxyl group is substituted with a protecting group such as a trimethylsilyl group, deprotection is performed. Deprotection can be carried out, for example, by heating in the presence of an alcohol.
