Abstract: A silicone oil-based anhydrous cosmetic or dermatological anhydrous composition having a homogeneous fatty phase wherein said fatty phase contains a silicone oil having the formula ##STR1## wherein R represents alkyl having 1 to 30 carbon atoms, aryl or aralkyl,n represents a whole number between 0 and 100, andm represents a whole number between 0 and 100, provided that the sum of n + m is between 1 and 100; and(ii) a wax in an amount ranging from 3 to 50 percent by weight based on the total weight of said fatty phase having a melting point between 50.degree. and 135.degree. C., comprising at least polymer having a molecular weight between 200 and 1,500 and selected from ethylene homopolymers and copolymers, and a monomer having the formula:CH.sub.2 .dbd.CH--R' (II)whereinR' represents alkyl having 1 to 30 carbon atoms, aryl or aralkyl.

Abstract: Porous microspheres have fixed on the exterior surface thereof a coating of at least one of a perfluorinated oil, a fluorinated silicone oil or a silicone gum. The pores of the microspheres can be charged with a hydrophilic, lipophilic or perfluorinated phase. The microspheres are employed in cosmetic compositions.
