Abstract
Composition in the form of a stable dispersion. This composition comprises: (a) from 60 to 98% by weight of an aqueous phase, and (b) from 2 to 40% by weight of an oily phase, said oily phase being dispersed in said aqueous phase and stabilized using cubic gel particles, said particles being essentially formed of: (i) 0.1 to 15% by weight, relative to the total weight of the composition, of at least one component selected from the group consisting of 3,7,11,15-tetramethyl-1,2,3-hexadecanetriol or phytanetriol, N-2-alkoxycarbonyl derivatives of N-methylglucamine and unsaturated fatty acid monoglycerides, and (ii) 0.05 to 3% by weight, relative to the total weight of the composition, of a dispersing and stabilizing agent, said agent being selected from the group consisting of surface-active agents which are water-soluble at room temperature, containing a linear or branched, saturated or unsaturated fatty chain having from 8 to 22 carbon atoms. Use in particular in the cosmetic, dermatological and pharmaceutical fields.
