  • Patent number: 12226509
    Abstract: Provided is a composition, in the form of an emulsion comprising a polyester from the esterification, with a polycarboxylic acid, of an aliphatic hydroxycarboxylic acid ester comprising at least two hydroxyl groups and at least one nonionic cellulose derivative comprising one or more hydrophobic substituents containing from 8 to 30 carbon atoms. Also provided is a composition comprising an active agent chosen from C-glucoside derivatives, a pasty fatty substance and a nonionic cellulose derivative comprising one or more hydrophobic substituents containing from 8 to 30 carbon atoms. Emulsions are made possible containing pasty fatty substances that are stable, even without an emulsifying surfactant or with a low content thereof (for example less than 3%), and which afford good sensory pleasure, even when the composition comprises a high content of pasty fatty substances. The emulsions can also contain active agents chosen from C-glucoside derivatives and cucurbic acid derivatives that are stable.

    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.
