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.
Claims2
An improved hydrophobic, low bulk density dispersible, high-loading cosmetic material with a low surface area-to-volume ratio, comprising a pulverized inorganic cosmetic pigment material coating coupled to from 15 to 35% of an organic polymeric microspherical powder of diameter less than 100 microns said microspherical powder being selected from the group consisting of polyethylene, polymethylmethacrylate and nylon copolymers by from 1 to 5% of a titanate coupling agent said coupling agent wherein the inorganic material has a particle size sufficiently smaller than the organic microspheres that the coupled product has a generally spherical particulate shape, said inorganic cosmetic material and said cosmetic material being capable of being coupled by said titanate coupling agent.
