Alcohol-free emulsions based on nonionic surfactants, anionic amphiphilic lipids, and fat-soluble organic UV screening agents

摘要

The present invention is an oil-in-water emulsion containing oil droplets having a number average diameter of 200.0 nm or less, comprising a) a continuous aqueous phase, b) an oily phase dispersed in the aqueous phase, and c) (i) at least A mixture of non-ionic surfactants comprising one alkoxylated fatty ester and (ii) at least one fatty ester of glycerol; d) at least one anionic amphiphilic lipid; and e) at least one. With a fat-soluble organic UV screening agent, free of monoalcohols containing 2 to 8 carbon atoms, and the amount of oily phase relative to the total amount of nonionic surfactants and anionic amphiphilic lipids The present invention relates to an oil-in-water emulsion characterized by having a mass ratio of 2 to 20. The invention also relates to a cosmetic method for limiting the darkening of the skin and / or improving the color and / or uniformity of the facial skin, including the application of the composition as defined above to the surface of a keratin substance. The present invention also relates to a cosmetic method for preventing and / or treating signs of aging of keratin materials, comprising the application of a composition as defined above to the surface of keratin materials. The invention also relates to a cosmetic method for moisturizing keratin materials, comprising the application of a composition as defined above to the surface of keratin materials.
