Patent ID: 8506941

Claim:
An agent for treating keratin-containing fibers comprising, in a cosmetically acceptable carrier: (a) at least one amphiphilic, cationic polymer having 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), wherein R 1 and R 4 are, independently of one another, a hydrogen atom or a methyl group, X 1 and X 2 are, independently of one another, an oxygen atom or an NH group, A 1 and A 2 are, independently of one another, an ethane-1,2-diyl, propane-1,3-diyl or butane-1,4-diyl group, R 2 , R 3 , R 5 and R 6 are, independently of one another, a (C 1 to C 4 ) alkyl group, and R 7 is a (C 8 to C 30 ) alkyl group, and (b) at least one additional film-forming cationic and/or setting cationic polymer having at least one structural unit of Formula (I), at least one structural unit of Formula (V) and at least one structural unit of Formula (VI) wherein R 1 and R 4 are, independently of one another, a hydrogen atom or a methyl group, A 1 and A 2 are, independently of one another, an ethane-1,2-diyl, propane-1,3-diyl or butane-1,4-diyl group, R 2 , R 3 , R 5 and R 6 are independently of one another, a (C 1 to C 4 ) alkyl group, and R 7 is a (C 8 to C 30 ) alkyl group.
