W/o composition comprising ionically crosslinked cationic polymer selected from chitosans and polylysines

Abstract

A composition contains a plurality of aqueous phases comprising: (a) at least one cationic polymer; (b) at least one non-polymeric acid having two or more pKa values or a salt thereof; and (c) water, and a fatty phase comprising: (d) at least one oil. The aqueous phases are dispersed in the fatty phase, and the (a) cationic polymer is selected from the group consisting of polylysines, chitosans and mixtures thereof, preferably from chitosans. The composition can provide a keratin substance such as skin with, at least, good hydration.
