Abstract
The conditioning performance of small particle size emulsified silicone in a surfactant-based shampoo composition can be significantly boosted by the inclusion in the shampoo composition of an amino functionalised silicone. Accordingly, the invention provides an aqueous shampoo composition comprising, in addition to water: PA1 i) at least one surfactant chosen from anionic, nonionic, zwitterionic or amphoteric surfactants or mixtures thereof; PA1 ii) an amino functionalised silicone; and PA1 iii) emulsified particles of an insoluble, non-amino functionalised silicone, in which the average silicone particle size of the emulsified non-amino functional silicone in the shampoo composition is less than 2 microns.
