  • Patent number: 5310578
    Abstract: A process for coating the surface of pigment and filler particles with an oleaginous and cosmetically functional material, characterized in that an aqueous suspension of the pigment or filler is mixed with an emulsion of said oleaginous material to be coated onto the surface of pigment or filler particles, followed by adding a component capable of breaking the emulsion to the thus obtained mixture, whereby the emulsified material coalesces onto the surface of the pigment or filler particles. The thus obtained pigments or fillers exhibit excellent properties when used in cosmetics.

  • Patent number: 5280019
    Abstract: A method of treating human skin to enhance the ability of skin in the absorption and retention of moisture in order to retard skin moisture loss. There is applied to skin an organosilicon compound exhibiting humectant-like characteristics which is a carboxylic acid salt functional polysiloxane. An alternate method treats human skin to reduce the transepidermal water loss of skin in order to enhance skin softness. There is applied to skin an occlusive film forming organosilicon compound which is a carboxyfunctional polysiloxane or its metal carboxylate salt.

  • Patent number: 5223251
    Abstract: Liquefiable powder compositions are disclosed for the delivery of fragrances. In particular, microporous cellulosic powders, such as cellulose acetates or nitrates, are disclosed as high liquid content vehicles for the delivery of fragrance preparations dissolved or dispersed in a liquid carrier. The resulting powders permit the application of the fragrance preparations by simply rubbing or otherwise applying the formulation onto the skin in such a manner that the powder liquefies and appears to vanish. Upon application, the frangible liquid loaded cellulosic powders break up into minute particles that do not pass easily beyond the initial layers of the skin, but do permit the slow release of the fragrance agent.
