Abstract
Agents for treating keratin-containing fibers, in particular human hair, and methods for the use of such agents are provided. The agent includes at least one copolymer (a) and at least one copolymer (b). The copolymer (a) includes at least one structural unit of a formula (I) and at least one structural unit of a formula (II). Copolymer (b) includes at least one structure unit of formula (AI) and at least one structural unit of formula (A2). The agent is contained in a cosmetically acceptable carrier.
Claims20
An agent for cosmetic treatment of keratin-containing fibers, in particular human hair, comprising:
- (a) at least one copolymer (a) comprising at least one structural unit of formula (I) and at least one structural unit of formula (II),
- in which
- R1 denotes a hydrogen atom or a methyl group,
- X1 denotes an oxygen atom or an NH group,
- A1 denotes an ethane-1,2-diyl, propane-1,3-diyl or butane-1,4-diyl group,
- R2 and R3 mutually independently denote a (C1 to C4) alkyl group,
- and
- (b) at least one copolymer (b) 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 C8) 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
- a cosmetically acceptable carrier.
A method of temporarily deforming hair and/or for hair care, the method comprising the steps of:
- applying an agent to the hair, wherein the agent comprises;
- (a) at least one copolymer (a) comprising at least one structural unit of formula (I) and at least one structural unit of formula (II),
- in which
- R1 denotes a hydrogen atom or a methyl group,
- X1 denotes an oxygen atom or an NH group,
- A1 denotes an ethane-1,2-diyl, propane-1,3-diyl or butane-1,4-diyl group,
- R2 and R3 mutually independently denote a (C1 to C4) alkyl group;
- and
- (b) at least one copolymer (b) 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 C8) alkyl group,
- R2 denotes a (C1 to C6) alkyl group,
- M denotes a hydrogen atom or an equivalent of a mono- or polyvalent cation.
