Abstract
A cosmetic or dermatological composition, comprising: an aqueous phase dispersed in an oily phase with a silicone emulsifying agent, wherein the viscosity of the composition, measured with a Rheomat 180 viscometer at a shear rate of 200 s−1 and at 25° C., ranges from 3 Pa·s (30 poises) to 20 Pa·s (200 poises), the aqueous phase constituting at least 78% by weight with respect to the total weight of the composition with the water of the aqueous phase constituting at least 65% of the total weight of the composition, and the emulsifying agent consisting of the dimethicone copolyol of formula (I): wherein R1 is 1 (C3H6O)(OC2H4)18(C3H6OH)18, p=394 and n=4.
