PURPOSE:To obtain a cosmetic providing a product having color tone corresponding to purpose and wide color tone, having excellent spread and smooth touch, free from make-up collapse, by adsorbing high-purity carthamin on cellulose acetate powder to give colored powder and adding the colored powder to a cosmetic. CONSTITUTION:High-purity carthamin having >=E(0.0006%/1cm)=0.10 is dissolved in an alkali aqueous solution, the solution is blended with cellulose acetate powder having 0.5-100mu average particle diameter, then fixed with an organic acid (e.g. citric acid or acetic acid), colored, separated, washed with water and dried to give colored powder. The amount of the powder blended is 1-70wt.% preferably 5-50wt.% based on total weight of cosmetic components. The color tone of the colored powder can be controlled by acetylation degree of cellulose acetate and pH of the solution in adsorption, color tone of orange is obtained at 40-54% acetylation degree, color tone of pink - reddish purple at 55-63% acetylation degree when the pH of the solution is fixed. The power can be adjusted to pink - orange by changing pH.
