  • Patent number: 6436383
    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: i) at least one surfactant chosen from anionic, nonionic, zwitterionic or amphoteric surfactants or mixtures thereof; ii) an amino functionalised silicone; and 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.

  • Patent number: 6277361
    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: i) at least one surfactant chosen from anionic, nonionic, zwitterionic or amphoteric surfactants or mixtures thereof; ii) an amino functionalised silicone; and 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.
