Product for treating keratin-containing fibers, especially human hair, comprising, in a cosmetically acceptable carrier: (a) at least one amphiphilic, cationic polymer, respectively comprising at least one structural unit of formulae (I) to (IV), wherein R 1 and R 4 are independently a hydrogen atom or a methyl group, X1 and X2 are independently an oxygen atom or an NH group, A 1 and A 2 are independently 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 a (C1-C4)-alkyl group, and R 7 is a (C 8 -C 30 )-alkyl group, and (b) at least one amphiphilic anionic polymer, comprising 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 a hydrogen atom or a methyl group, R 10 is (C 8 -C 30 )-alkyl group, M+ is a physiologically compatible cation, and A 3 is a *—(CH 2 CH 2 O) x —* group wherein x is a whole number between 5 and 35, a *—(CH 2 CHMeO) y —* group wherein y is a whole number between 5 and 35 or a *—(CH 2 CH 2 O) x —(CH 2 CHMeO) x —* group wherein the sum of x+y is a whole number between 5 and 35, and x and y are higher than zero. The invention also relates to the use of said product for temporary hair styling and for hair care, especially in the form of a hair cream or a hair gel. |
