Abstract
Abstract A cleaning composition suitable for the hair and/or skin, which comprises a cosmetically acceptable medium containing (a) at least one surface-active agent of the formula: <IMAGE> (I) in which R denotes a linear or branched alkyl group and M denotes an alkali metal or alkaline earth metal or an amine, and (b) at least one cationic polymer selected from (i) cellulose ether derivatives containing quaternary ammonium groups, (ii) cyclic polymers containing, as the main constituent of the chain, units corresponding to the formula (III), or (III') <IMAGE> (III) <IMAGE> (III') in which l and t are 0 or 1 and l+t=1, R'' denotes hydrogen or methyl, R''' and R' independently of one another denote an alkyl group having 1 to 22 carbon atoms, a hydroxyalkyl group or a lower amidoalkyl group or R''' and R', together with the nitrogen atom to which they are attached, denote a heterocyclic group and Y- denotes an anion, and (iii) copolymers containing said units of the formula (II) or (II') and units derived from acrylamide or from diacetoneacrylamide.
