A hair cosmetic is disclosed, which comprises the following components (a) and (b):
(a) a poly(N-acylalkyleneimine)-modified silicone having a poly(N-acylalkyleneimine) segment and an organopolysiloxane segment at a weight ratio of said poly(N-acylalkyleneimine) segment to said organopolysiloxane segment of from 1/20 to 20/1, and having a molecular weight of from 500 to 500,000, wherein said poly(N-acylalkyleneimine) segment comprises a repeating unit represented by the following formula (I):
wherein R1 represents a hydrogen atom, an alkyl group having 1 to 22 carbon atoms, a cycloalkyl group having 3 to 22 carbon atoms, an aralkyl group having 7 to 22 carbon atoms or an aryl group having 6 to 22 carbon atoms; and n is 2 or 3; and
(b) a film-forming polymer. The hair cosmetic of the present invention is effective in imparting a natural gloss, smoothness, flexibility, smooth-combing properties and water repellency to the hair without deteriorating the hair setting retention function.
本发明公开了一种头发化妆品,由以下成分(a)和(b)组成:
(a) 聚(N-酰基亚烷基亚胺)改性硅氧烷,具有聚(N-酰基亚烷基亚胺)段和有机聚硅氧烷段,所述聚(N-酰基亚烷基亚胺)段与所述有机聚硅氧烷段的重量比为 1/20 至 20/1,分子量为 500 至 500,000,其中所述聚(N-酰基亚烷基亚胺)段包括下式(I)所代表的重复单元:
其中 R1 代表氢原子、具有 1 至 22 个碳原子的烷基、具有 3 至 22 个碳原子的环烷基、具有 7 至 22 个碳原子的芳基或具有 6 至 22 个碳原子的芳基;且 n 为 2 或 3;以及
(b) 成膜聚合物。本发明的护发化妆品能有效地赋予头发自然光泽、顺滑度、柔韧性、梳理顺畅性和防水性,而不会降低头发的定型功能。
