Cosmetic hair composition
View Patent ↗The hair cosmetic composition contains a solvent-containing silicone emulsion (A) which is prepared by emulsifying a mixture of high-molecular-weight polyorganosiloxane (a) obtained by emulsion polymerization and a volatile solvent (b), a surfactant (B) and water (C). The component solvent-containing silicone emulsion (A) is contained at a ratio of 0.1-10 wt % as a total amount of the high-molecular-weight polyorganosiloxane (a) and the volatile solvent (b). And, the component surfactant (B) is contained at a ratio of 0.05-40 wt %. Hair is provided with outstanding smoothness and softness, and particularly good finger combing when rinsing the hair.
1. A hair cosmetic composition, comprising:
(A) a solvent-containing silicone emulsion which is prepared by emulsifying a mixture of an emulsion (a) and a volatile solvent (b), wherein the emulsion (a) contains a high-molecular-weight α, ω-dihydroxypolydimethylsiloxane, an anionic surfactant selected from the group consisting of polyoxyethylene (2) lauryl ether sulfate, polyoxyethylene (3) lauryl ether sulfate, and polyoxyethylene (4) lauryl ether sulfate, and/or lauryl sulfate, and water, wherein the high-molecular-weight α, ω-dihydroxypolydimethylsiloxane is obtained by emulsion polymerization of an α, ω-dihydroxydimethylsiloxane,
the volatile solvent (b) is decamethyl cyclopentasiloxane or isoparaffinic hydrocarbon having a boiling point in a range of 201 to 265°;
(B) one or more surfactants selected from an anionic surfactant, an amphoteric surfactant and a nonionic surfactant; and
(C) water,
wherein the solvent-containing silicone emulsion (A) is in the range of 0.1 to 10 wt % as a total amount of the high-molecular-weight α, ω-dihydroxypolydimethylsiloxane in the emulsion (a) and the volatile solvent (b), and the surfactant (B) is in the range of 0.05 to 40 wt %.
2. The hair cosmetic composition according to claim 1 , wherein the solvent-containing silicone emulsion (A) has an average particle diameter of 150 to 350 nm.
