  • Patent number: 5356617
    Abstract: New cosmetic raw materials are provided in the form of complexes of pigment materials coupled to small microspheres providing complexes that impart richness and feel, with low oil absorbency while displaying the optical and other properties of the pigment. Improvements in spatial disposition of small pigment particles provide a better dispersion of pigment in and products such as makeups, creams, lipsticks, blushers, nail enamels, and the like. Preferred embodiments include talc, nylon, silica, starches and iron oxide pigments coupled by a liquid titanate coupling agent to microspheres of polyvinylidene chloride copolymer, polyethylene, nylon and silica. Simple methods of manufacture include spraying a liquid titanate in solution on a blended mixture of pigment and microsphere and drying the product while blending, to cure it.

  • Patent number: 5314683
    Abstract: A method of coupling organic and inorganic cosmetic materials is disclosed. Spherical shaped powders have beneficial characteristics as applied to cosmetics. These characteristics include uniform reflectivity, improved dispersion and superior viscosity characteristics in the final product. Coupling inorganic pigments to organic microspheres provides the benefits associated with the microspheres and allows a greater loading of inorganics into a cosmetic without sacrificing the benefits of the microspheres.
