Abstract
The invention provides a personal cleansing composition comprising, in an aqueous continuous phase: (i) from 5 to 30% by weight of one or more anionic cleansing surfactants; (ii) from 0.1 to 10% by weight of discrete, dispersed droplets of emulsified silicone with a mean diameter (D3,2) of 4 micrometres or less; (iii) from 0.1 to 5% by weight of microcapsules in which a core comprising benefit agent is encapsulated in a polymeric shell, and (iv) from 0.1 to 0.5% by weight of a combination of cationic polymers comprising: (a) at least one cationic polygalactomannan derivative having a mean charge density at pH 7 from 0.2 to 2 meq per gram; and (b) at least one acrylamidopropyltrimonium chloride/acrylamide copolymer having a mean charge density at pH 7 from 1 to 3 meq per gram.
