Abstract:
The present invention relates to a novel coloring material including a polyamide powder and/or a polyurethane powder and a water-soluble dye. The coloring material of the present invention allows a water-soluble dye to be used in anhydrous formulations. Thereby, the range of use of dyes may be widened, reflectance may be excellent, and fluorescence properties may be obtained. Accordingly, the present invention may broaden the spectrum of cosmetic coloring materials used in limited applications in the cosmetic field.
