ABSTRACT:
A description is given of the use of a nanodispersion, which comprises(a) a membrane-forming molecule,(b) a coemulsifier and(c) a lipophilic component,in cosmetic end formulation, which nanodispersion is obtainable by(α) mixing the components (a), (b) and (c) until a homogeneous clear liquid is obtained, and(β) adding the liquid obtained in step (α) to the water phase of the cosmetic end formulations, steps (α) and (β) being carried out without any additional supply of energy.The nanodispersions used according to this invention can be easily prepared and are suitable as carrier systems for a very wide range of cosmetic active agents and oil-soluble dyes.
