Cosmetic hair composition

Abstract

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.
