A subject-matter of the present invention is a cosmetic composition in the form of an oil-in-water emulsion comprising: (1) at least one organopolysiloxane elastomer; (2) at least one hydrophobic silica; and (3) at least one gemini surfactant of formula (I): in which R 1 and R 3 denote, independently of one another, an alkyl radical having from 1 to 25 carbon atoms; R 2 denotes a spacer consisting of a linear or branched alkylene chain having from 1 to 12 carbon atoms; X and Y denote, independently of one another, a -(C 2 H 4 O) a -(C 3 H 6 O) b Z group; and n ranges from 1 to 10. The composition in accordance with the invention makes it possible to obtain mattifying properties and/or to mask skin imperfections while having good cosmetic properties, such as softness and freshness on application, a non-greasy finish, an ease of penetration and good moisturisation of the skin. |
