  • Patent number: 7871600
    Abstract: A leave on hair care composition comprising a) a wax dispersion; and b) an aqueous oil emulsion wherein the oil phase is a liquid and comprises: i) one or more non-volatile oils, where the dynamic viscosity of any single non-volatile oil or the dynamic viscosity of a blend of non-volatile oils is less than 1000 mPa·s at 35° C. and 5 s-1; ii) an oil dispersible structurant such that the dynamic viscosity of the structured oil phase at 35° C. prior to formation of the emulsion is at least 50,000 mPa·s at a shear rate of 0.5 s-1 and is less than 6,000 mPa·s at a shear rate of 500 s-1.

  • Patent number: 6432420
    Abstract: The invention provides a hair treatment composition such as a shampoo or conditioner suitable for topical application to hair for the repair and prevention of damage, comprising (i) cholesterol, and (ii) a hair benefit agent which is a mixture of a basic amino acid and a fatty acid. Preferably the cholesterol and hair benefit agent are compounded into a dispersion of multilamellar vesicles, stabilised with nonionic surfactant.
