Abstract

Abstract 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 R 1 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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 118 words
A hair cosmetic comprising 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 R 1 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.
Claim 2
Dependent Claim 118 words
A hair cosmetic comprising 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 R 1 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.
Claim 3
Dependent Claim 38 words
A hair cosmetic of claim 1, wherein said film-forming polymer is a compound selected from polyvinyl pyrrolidone polymer compounds, acidic acryl polymer compounds, amphoteric acryl polymer compounds, basic acryl polymer compounds, cellulose derivatives, chitin derivatives and chitosan derivatives.
Claim 4
Dependent Claim 30 words
A hair cosmetic of claim 1, wherein said poly(N-acylalkyleneimine)-modified silicone amounts from 0.01 to 10 % by weight and said film-forming polymer amounts from 0.05 to 20 % by weight.
Claim 5
Dependent Claim 66 words
A hair cosmetic of claim 1, wherein said poly(N-acylalkyleneimine)-modified silicone having a poly(N-acylalkyleneimine) segment and an organopolysiloxane segment is a compound prepared by the steps of: (i) ring-opening polymerizing a cyclic imino ether compound represented by the following formula (II): wherein R 1 and n are as defined above; and (ii) polymerizing a reaction product of the step (i) with an organopolysiloxane having a functional group.
