Alcohol-free emulsion based on nonionic surfactants, on an anionic amphiphilic lipid and on liposoluble organic uv-screening agents

Abstract

The present invention relates to an oil-in-water emulsion with globules of oil, the number-average size of which is less than or equal to 200.0 nm, comprising: a) a continuous aqueous phase, b) an oily phase dispersed in said aqueous phase, c) a mixture of nonionic surfactants comprising: (i) at least one alkoxylated fatty ester, and (ii) at least one fatty ester of glycerol, d) at least one anionic amphiphilic lipid, e) at least one liposoluble organic UV-screening agent, characterized in that it does not comprise any monoalcohol comprising from 2 to 8 carbon atoms, and that the weight ratio of the amount of oily phase to the total amount of nonionic surfactants and anionic amphiphilic lipid is from 2 to 20. The invention also relates to a cosmetic process for limiting the darkening of the skin and/or improving the colour and/or uniformity of the complexion, comprising the application, to the surface of the keratin material, of a composition as defined previously. It also relates to a cosmetic process for preventing and/or treating the signs of ageing of a keratin material, comprising the application, to the surface of the keratin material, of a composition as defined previously. It also relates to a cosmetic process for moisturizing a keratin material, comprising the application, to the surface of the keratin material, of a composition as defined previously.
