Abstract
The present application relates to expanded solid compositions whose matrix comprises a cellular network formed from a starch-rich product and contains size-graded spheroidal polyamide particles. These compositions constitute new dosage forms for cosmetic or dermatological use. These compositions take either the form of expanded cylinders, pellets, leaves or flakes, or the form of powder. When reduced to the powder state, these compositions may also be used as pulverulent phase in make-up compositions, in particular make-up powders. They may be stored in the dry state and capable of being partially rehydrated after immersion in water to reconstitute make-up removal or gentle exfoliating compositions for the skin, body, face and/or neck.
