Quaternized polyamine polymers are employed in cosmetic compositions for application to the hair or skin. The polymer has recurring units of the formula: <IMAGE> WHEREIN A is polymethylene having 2-10 carbon atoms, B is selected from polymethylene having 3-10 carbon atoms, xylylidenyl group -CH2-C6H4-CH2- ortho, meta or para, -(CH2)x-O-(CH2)x- wherein x is 2 or 3, or -CH2-CHOH-CH2-; R1 and R3 represent an aliphatic radical having 1-12 carbon atoms; R2 and R4 represent an aliphatic radical having 1-20 carbon atoms; R5 is hydrogen or an aliphatic, alicyclic, aryl or arylaliphatic radical containing 1-20 carbon atoms; R6 is an aliphatic or arylaliphatic radical containing 1-20 carbon atoms; X is a halide anion; Y is selected from a halide anion, SO4H(-) or CH3SO4(-) ; and n and p are whole numbers with p being able to be 0, such that the ratio p/n+p ranges from 0 to 0.95. |
