Patent ID: 8685377

Claim:
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, R 7 is a (C 8 to C 30 ) alkyl group, and b) 0.1 wt % to 20.0 wt. %, based on total weight of the agent of at least one film-forming anionic and/or setting anionic polymer having at least one structural unit of Formula (V) and at least one structural unit of Formula (VI), wherein R 8 and R 9 are, independently of one another, a hydrogen atom or a methyl group, with the proviso that R 8 and R 9 are not simultaneously methyl, R 10 is a hydrogen atom or a methyl group, R 11 is a carbamoyl group, a linear or branched (C 4 to C 12 ) alkylaminocarbonyl group, a linear or branched (C 4 to C 12 ) alkylaminoethyl-aminocarbonyl group, a linear or branched (C 4 to C 12 ) alkylaminopropyl-aminocarbonyl group, a linear or branched (C 4 to C 12 ) alkyloxycarbonyl group, a linear or branched (C 4 to C 12 ) alkylaminoethyloxycarbonyl group, a linear or branched (C 4 to C 12 ) alkylaminopropyloxycarbonyl group, a linear or branched (C 2 to C 12 ) acyloxy group, A 3 is a hydroxyl group or an organic group having at least one sulfonic acid group that bonds through an oxygen atom or an NH group to the structural fragment.
