Abstract
A composition in the form of an anhydrous gel containing a wax-free fatty phase in which are dispersed an organomodified clay, expanded thermoplastic hollow particles of polymer or copolymer formed from a monomer or a mixture of monomers containing ethylenic unsaturation and a pyrogenous silica, as well as to its uses in topical application. This composition has a creamy, non-greasy, smooth and melting texture and good stability over time. It may be used as a base for make-up products or care products for the skin and/or the face.
