Abstract
Agents for treating keratin-containing fibers, in particular human hair, are provided. The agents comprise, in a cosmetically acceptable carrier, (a) at least one amphiphilic cationic polymer comprising respectively at least one structural unit of the formulae (I) to (IV), as provided herein, and (b) at least one copolymer comprising at least one structural unit of formula (A1) and at least one structural unit of formula (A2), as provided herein, the use of said agent for temporarily styling hair and for hair care, in particular as an aerosol hairspray or an aerosol hair mousse.
Claims19
A cosmetic agent for cosmetic treatment of keratin-containing fibers comprising:
- (a) about 0.1 wt. % to about 5.0 wt. %, relative to the weight of the agent, of at least one amphiphilic cationic polymer comprising at least one structural unit of formula (I), at least one structural unit of formula (II), at least one structural unit of formula (III), and at least one structural unit of formula (IV),
- in which
- R1 and R4 mutually independently denote a hydrogen atom or a methyl group,
- X1 and X2 mutually independently denote an oxygen atom or an NH group,
- A1 and A2 mutually independently denote an ethane-1,2-diyl group, propane-1,3-diyl group, or butane-1,4-diyl group,
- R2, R3, R5, and R6 mutually independently denote a (C1 to C4) alkyl group,
- R7 denotes a (C8 to C30) alkyl group,
- (b) about 0.1 wt. % to about 5.0 wt. %, relative to the weight of the agent, of at least one copolymer comprising at least one structural unit of formula (A1) and at least one structural unit of formula (A2),
- in which
- R1 denotes a (C1 to C18) alkyl group,
- R2 denotes a (C1 to C6) alkyl group,
- M denotes a hydrogen atom or an equivalent of a mono- or polyvalent cation, and
- (c) a cosmetically acceptable carrier
- wherein the ratio (W/W) of the at least one copolymer (a) to the at least one copolymer (b) is about 5:1 to 1:5.
A method for treating keratin-containing fibers, the method comprising:
- applying a cosmetic agent to keratin-containing fibers, the cosmetic agent comprising:
- (a) about 0.1 wt. % to about 5.0 wt. %, relative to the weight of the agent, of at least one amphiphilic cationic polymer comprising at least one structural unit of formula (I), at least one structural unit of formula (II), at least one structural unit of formula (III), and at least one structural unit of formula (IV),
- in which
- R1 and R4 mutually independently denote a hydrogen atom or a methyl group,
- X1 and X2 mutually independently denote an oxygen atom or an NH group,
- A1 and A2 mutually independently denote an ethane-1,2-diyl group, propane-1,3-diyl group, or butane-1,4-diyl group,
- R2, R3, R5, and R6 mutually independently denote a (C1 to C4) alkyl group,
- R7 denotes a (C8 to C30) alkyl group,
- (b) about 0.1 wt. % to about 5.0 wt. %, relative to the weight of the agent, of at least one copolymer comprising at least one structural unit of formula (A1) and at least one structural unit of formula (A2),
- in which
- R1 denotes a (C1 to C18) alkyl group,
- R2 denotes a (C1 to C6) alkyl group,
- M denotes a hydrogen atom or an equivalent of a mono- or polyvalent cation, and
- (c) a cosmetically acceptable carrier
- wherein the ratio (W/W) of the at least one copolymer (a) to the at least one copolymer (b) is about 5:1 to 1:5.
