    Abstract: Cosmetic emulsion containing a gemini surfactant and a lipophilic polymer The invention relates to a composition in the form of an emulsion, in particular in the form of an oil-in-water emulsion, comprising a gemini surfactant having a specific chemical structure with at least two fatty amide groups and at least one lipophilic polymer comprising at least hydroxyethyl acrylate units and acrylate units bearing a lipophilic group, wherein the weight ratio of the sum of all the hydroxyethyl acrylate units to the sum of all the acrylate units bearing a lipophilic group ranges from 1:30 to 1:1 and wherein the lipophilic polymer has a number-average molecular weight Mn ranging from 2000 to 9000 g/mol. The composition in accordance with the invention makes it possible to obtain a cosmetic emulsion having an increased sun protection factor, while at the same time having good cosmetic properties, such as a non-greasy and non-tacky feel, while at the same time being stable, in particular from the physicochemical viewpoint.

    Abstract: The present invention relates to a composition for topical application comprising at least one fatty phase; at least one volatile hydrocarbon-based oil; and at least one lipophilic polymer comprising at least hydroxyethyl acrylate units and acrylate units bearing a lipophilic group, the weight ratio of the sum of all the hydroxyethyl acrylate units to the sum of all the acrylate units bearing a lipophilic group ranging from 1:30 to 1:1 and the lipophilic polymer having a number-average molecular weight Mn ranging from 2000 to 9000 g/mol. The composition in accordance with the invention has improved sensory properties, allowing faster and more complete absorption into the skin. In particular, the composition in accordance with the invention leaves a non-greasy and non-tacky feel on the skin, during and after application, even in the presence of solid fatty substances such as waxes.
