A hair cosmetic composition including components (A) to (C), wherein the content of component (A) is 0.01 to 5.00% by mass and the content of component (B) is 5.00 to 96.77% by mass: (A) an epoxyaminosilane copolymer, which is a reaction product of compounds (a) to (d): (a) a polysiloxane having two or more oxiranyl groups or oxetanyl groups; (b) a polyether having two or more oxiranyl groups or oxetanyl groups; (c) aminopropyltrialkoxysilane; (d) a specific amine; (B) a micelle formation inhibitor selected from (b1) to (b3): (b1) an organic compound having a solubility parameter δ H of 10.0 to 15.8 MPa 1/2 , excluding (b3); (b2) a compound selected from ethanol and the like; (b3) an organic salt; (C) water.

First claim

Opening claim text (preview).

The invention claimed is: 1. A hair cosmetic composition comprising the following components (A) to (C), wherein a content of component (A) is 0.2% by mass to 2.00% by mass, a content of component (B) is 15% by mass to 95% by mass, and a mass ratio of component (B) to component (A), (B)/(A), is 20 to 93.5: (A) polysilicone-29; (B) ethanol; and (C) water, wherein the hair cosmetic composition has a pH of 1.0 to 4.0. 2. The hair cosmetic composition according to claim 1 , which is applied to hair and then dried without being rinsed off. 3.
