Abstract

A quaternized polymer for use as a cosmetic agent, has recurring units of the formula ##STR1## wherein R is lower alkyl or --CH.sub.2 --CH.sub.2 OH; PA0 R' is an aliphatic, alicyclic or arylaliphatic radical containing a maximum of 20 carbon atoms, or R and R' together with the nitrogen atom to which they are attached form a heterocycle capable of containing a heteroatom other than nitrogen; PA0 A is a divalent group selected from ##STR2## wherein x, y and t are whole numbers ranging from 0 to 11 such that the sum (x+y+t) is greater than or equal to 0 and lower than 18, and E and K represent hydrogen or an aliphatic radical having less than 18 carbon atoms, EQU --(CH.sub.2).sub.n --S--(CH.sub.2).sub.n --, (3) EQU --(CH.sub.2).sub.n --O--(CH.sub.2).sub.n --, (4) EQU --(CH.sub.2).sub.n --S--S--(CH.sub.2).sub.n --, (5) EQU --(CH.sub.2).sub.n --SO--(CH.sub.2).sub.n --, (6) EQU --(CH.sub.2).sub.n --SO.sub.2 --(CH.sub.2).sub.n --and (7) ##STR3## wherein n is equal to 2 or 3; B represents a divalent group selected from ##STR4## wherein D and G represent hydrogen or an aliphatic radical having less than 18 carbon atoms and v, z and u are whole numbers ranging from 0 to 11, with two of v, z…
