ABSTRACT:
The present invention relates to expanded solid compositions whose matrix comprises a cellular network formed from a starch-rich product and contains at least some expanded thermoplastic hollow particles of polymer or copolymer of an ethylenically unsaturated monomer or mixture of such monomers. These compositions constitute new dosage forms for cosmetic or dermatological use. These compositions either take the form of expanded cylinders, pellets, leaves or flakes, or the form of powder. When reduced to the powder state, they may also be used as a make-up or hygiene composition to be rehydrated or to be used as such.
