  • Patent number: 6447792
    Abstract: The present invention relates to the use in cosmetics of rigid gels containing at least 20% by weight of one or more water-soluble or hydrophilic gelling agent(s) which may be obtained from the said water-soluble or hydrophilic gelling agent in the presence of water by mixing, blending, compression and extrusion in a twin-screw extruder. These gels constitute novel pharmaceutical forms for cosmetic or dermatological use. These gels are generally in the form of sticks, pencils or cakes. They may be aqueous with a matrix consisting of an aqueous gelled network. They may be in anhydrous form with a matrix consisting of a dehydrated gelled network. They may constitute many products in solid form applied to making up, to care of and/or to treatment of the skin, the scalp, the hair or the mucous membranes, or alternatively applied to the hygiene of the body, the skin, the scalp, the hair or the mucous membranes.

  • Patent number: 6007830
    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.

  • Patent number: 5976596
    Abstract: For preparing an extrusion-cooked food product, a food component emulsifier is combined with water to obtain an aqueous dispersion of the emulsifier, and the dispersion is fed into an extruder for being mixed with food components being mixed and heated in the extruder to prepare the extrusion-cooked product.

  • Patent number: 5965179
    Abstract: To incorporate water into a chocolate, chocolate and an emulsion or dispersion of a thickening or gelling substance in water, particularly a dispersion of microcrystalline cellulose in water, are introduced into an extruder and mixed and passed to an extruder nozzle so that the chocolate mass extrudate from the nozzle has a temperature of from 0.degree. C. to 28.degree. C.

  • Patent number: 5900241
    Abstract: The use in cosmetics of expanded solid compositions whose matrix contains an alveolar network made from a natural product or from a derivative of a natural product capable of being expanded. These compositions constitute novel galenic forms for cosmetic or dermatological use. These compositions may be in the form of rolls, pellets, sheets or flakes which are expanded or in the form of powder. When reduced to a powdered state, these compositions can also be rehydrated or employed as a pulverulent phase in make-up compositions, in particular, in compacted make-up powders.

  • Patent number: 5763500
    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.
