  • Patent number: 6254877
    Abstract: The present invention relates to a care and/or make-up anhydrous composition, in particular a cosmetic, dermatological, hygienic or pharmaceutical composition, for the skin, which may be provided in the form of a cast product or a gel comprising at least one, in particular pulverulent, coloring matter and a dispersion of non-film-forming polymer particles which are surface-stabilized in a partially nonvolatile liquid fatty phase. Depending on the quantity of polymer and of nonvolatile oil, it is possible to obtain, on the lips or the skin, a nonfatty soft film having remarkable transfer-free properties, while imparting a very high degree of comfort. The invention also relates to the use of this dispersion in such a composition.

  • Patent number: 6214318
    Abstract: Aerosol compositions are provided that enhance the therapeutic action of ointments by producing, upon topical application thereof, a sustained cooling effect that provides fast relief form pain and itching as well as a tendency to shrink swollen, inflamed tissue. The compositions contain oils, thickening agents for the oils, and propellant. Aqueous solutions, therapeutic ingredients and various adjuvants may also be present. The specific propellant and the proportion used are selected to provide a deposit with a temperature of about −5° C. to about +5° C. In this temperature range, the deposit is cold enough for the required therapeutic effect, but not so cold as to cause pain or tissue damage. The choice and proportion of thickening agents used are selected to provide a deposit that does not flow or spread. Were the deposit to spread, it would present a large surface area from which propellant present in the deposit would evaporate rapidly.
