A quaternized polymer for use as a cosmetic agent, has recurring units of the formula <IMAGE> wherein R is lower alkyl or -CH2-CH2OH; 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; A is a divalent group selected from o-, m- or p-xylylidene of the formula (1) <IMAGE> <IMAGE> (2) 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, -(CH2)n -S-(CH2)n-, (3) -(CH2)n-O-(CH2)n-, (4) -(CH2)n-S-S-(CH2)n-, (5) -(CH2)n-SO-(CH2)n-, (6) -(CH2)n-SO2-(CH2)n-and (7) <IMAGE> (8) wherein n is equal to 2 or 3; B represents a divalent group selected from o-, m- or p-xylylidene of the formula (1) <IMAGE> <IMAGE> (2) 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 and u simultaneously being capable of being 0, such that the sum (v+z+u) is greater than or equal to 1 and lower than 18 and such that the sum (v+z+u) is greater than 1 when the sum (x+y+t) is equal to 0, <IMAGE> (3) (CH2)nO(CH2)n (4) - wherein n is 2 or 3; and X(-)is an anion derived from an organic or mineral acid. The quaternized polymer is employed in cosmetic compositions for the hair and skin.
