摘要

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 R1 and R4 are independently a hydrogen atom or a methyl group, X1 and X2 are independently an oxygen atom or an NH group, A1 and A2 are independently an ethane-1,2-diyl, propane-1,3-diyl or butane-1,4-diyl group, R2, R3, R5 and R6 are independently a (C1-C4)-alkyl group, and R7 is a (C8-C30)-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 R8 and R9 are independently a hydrogen atom or a methyl group, R10 is (C8-C30)-alkyl group, M+ is a physiologically compatible cation, and A3 is a *—(CH2CH2O)x—* group wherein x is a whole number between 5 and 35, a *—(CH2CHMeO)y—* group wherein y is a whole number between 5 and 35 or a *—(CH2CH2O)x—(CH2CHMeO)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.
