Composition suitable for treating the hair or skin, which conains at least one poly-(quaternary ammonium) polymer having units of the formula: <IMAGE> (I) in which A denotes an alkylene, hydroxyalkylene, alkenylene or alkynylene radical; B denotes: (a) -O-Z-O- in which Z denotes a hydrocarbon radical or a group <IMAGE> +TR <IMAGE> in which x and 4 denote a number from 1 to 4; (b) a bis-secondary diamine radical; (c) a radical -NH-Y-NH- in which Y denotes a hydrocarbon radical or the radical -CH2-CH2-S-S-CH2-CH2-; or (d) a group -NH-CO-NH-; R1 denotes C1-C4 alkyl; R2 denotes a hydrocarbon radical or two R2 radicals can complete a radical <IMAGE> X denotes a halide; and n is 1 or an integer from 3 to 10. The polymers used in the composition of the invention have a good compatibility with anionic surface-active agents, are degradable and do not accumulate on the hair. |
