  • Coated powder and cosmetic prepared by blending the same
    Patent number: 6740315
    Abstract: Coated powder is obtained by applying a material having a refractive index of 1.9 to 3.1 to powder having a refractive index of 1.3 to 1.8 as a core and further applying a material having a refractive index of 1.3 to 1.8 to the coated core. When this powder is used for cosmetics or paints, natural coloring can be accomplished without deteriorating lightness because a screening effect is not high.
    Type: Grant
    Filed: March 17, 1999
    Date of Patent: May 25, 2004
    Assignee: Pola Chemical Industries, Inc.
    Inventors: Kazuhiro Nishikata, Hirochika Nishimura

  • Method for evaluating make-up cosmetic product and powder composition
    Patent number: 5888879
    Abstract: A make-up cosmetic product, which enhances the appearance of complexion, is evaluated by irradiating lights having a wavelength range of visible light onto a surface on which the make-up cosmetic product is applied, from at least two directions with different incident angles, measuring a plurality of spectra of reflected lights obtained from the irradiated lights, respectively, and comparing the spectrum patterns with each other. This clarifies the optical theory by which the skin looks beautiful and provides a method for evaluating a make-up cosmetic product making the skin look beautiful.
