Abstract
Improved conditioning performance from a surfactant-based shampoo composition can be achieved by the inclusion in the shampoo composition of a specific combination of silicones, namely amino functionalised silicone and high viscosity non-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 viscosity of the silicone itself is at least 500,000 cst, preferably at least 1,000,000 cst.
