The present application relates to an oil-in-water nanoemulsion comprising an oily phase dispersed in an aqueous phase in which the oil globules have an average size of less than 100 nm, characterized in that it comprises at least one amphiphilic lipid chosen from nonionic amphiphilic lipids, anionic amphiphilic lipids and their mixtures, and at least one anionic polymer comprising at least one hydrophobic chain, and in that the weight ratio of the amount of oily phase to the amount of amphiphilic lipid ranges from 1, 2 to 10. The anionic polymer can in particular be a copolymer of acrylic or methacrylic acid or a copolymer of 2-acrylamido-2-methylpropane sulfonic acid, in particular a terpolymer. The nanoemulsion obtained is transparent and stable on storage. It can constitute a composition for topical and in particular cosmetic or dermatological use, a pharmaceutical composition or an ophthalmological composition. |
