    • PROBLEM TO BE SOLVED: To provide a colored titanated mica having excellent dichroism and transmission light with high chroma and useful as a powdery cosmetic for the control of the skin color to make the dark spot of the skin inconspicuous.
      SOLUTION: Titanated mica particle is coated with fine iron oxide powder having an average particle diameter of 60-150 nm. The product is used as a skin color controlling agent for making the dark spot of the skin inconspicuous (a substance having a transmission interference color complimentary to the color of the skin to be controlled). The transmitted interference color is not weakened with the coloring agent because the product has small absorption of light with the surface iron oxide.

    • 要解决的问题:提供一种具有优异的二色性和透明光的彩色钛白云母,具有高色度,并且可用作粉状化妆品,用于控制皮肤颜色,使皮肤的黑斑不显眼。 解决方案:钛酸云母颗粒涂覆有平均粒径为60-150nm的细小的氧化铁粉末。 该产品用作皮肤颜色控制剂,用于使皮肤的黑斑不显眼(具有与待控制的皮肤颜色互补的透射干涉色的物质)。 由于产品与表面氧化铁的光吸收小,因此着色剂不会减弱透射干涉色。

    • PURPOSE: To obtain a composition for adjusting skin color capable of making dark colored parts in the skin caused by a nevus, a hemangioma, a ruddy face, spots, freckles, etc., inconspicuous. CONSTITUTION: This composition for adjusting skin color comprises blending >=10-wt.% preferably >=25wt.% material based on the total amount of powder, having a transmitted light in the color range of a complementary color or of the vicinity of the complementary color against a skin color for adjusting. As the above material, in the case of the dark colored parts having a reddish color, the material having the transmitted light with a maximum reflection peak at 400-550nm (blue to greenish), e.g. a titanium dioxide covered mica produced by covering the mica with the titanium dioxide having 190-270nm or 405-500nm optical membrane thickness, and in the case of the dark colored parts having a blueish color, a material having the transmitted light with a minimum reflection peak at 400 550nm (yellow to reddish), e.g., the titanium dioxide covered mica produced by covering the mica with titanium dioxide having 290-380nm or 530-660nm optical membrane thickness are cited. Since the composition takes the advantage of filtering effects, it can make the dark colored part inconspicuous in a natural way without damaging the transparent feeling of the skin.
