  • Method for Manufacturing Highly Iridescent Titanium Oxide Composition
    Publication number: 20120128604
    Abstract: A highly iridescent titanium oxide composition, which not only produces new and outstanding luster as well as color brightness within a recognized color range by interference colors but also retains clear complementary colors. The highly iridescent titanium oxide composition is a coating composition forming a coating layer over the surface of a thin flake-shaped matrix, whose size is 50-800 ?m. The coating layer is 0.05-0.6 ?m thick containing a titanium composition whose content is 70-95% by mass. This titanium oxide-contained coating layer is the highly iridescent titanium oxide composition exfoliated from the coating composition. The highly iridescent titanium oxide composition is a beneficial element, especially as a cosmetic ingredient.
