Abstract
Composition suitable for treating the hair or skin, which conains at least one poly-(quaternary ammonium) polymer having units of the formula: ##STR1## in which A denotes an alkylene, hydroxyalkylene, alkenylene or alkynylene radical; PA1 B denotes: PA2 (a) --O--Z--O-- in which Z denotes a hydrocarbon radical or a group ##STR2## in which x and 4 denote a number from 1 to 4; (b) a bis-secondary diamine radical; PA2 (c) a radical --NH--Y--NH-- in which Y denotes a hydrocarbon radical or the radical --CH.sub.2 --CH.sub.2 --S--S--CH.sub.2 --CH.sub.2 --; or PA2 (d) a group --NH--CO--NH--; PA1 R.sub.1 denotes C.sub.1 -C.sub.4 alkyl; R.sub.2 denotes a hydrocarbon radical or two R.sub.2 radicals can complete a radical ##STR3## 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.
