PURPOSE: To obtain a color tone cosmetic composition without requiring a complex treating process and excellent in color-expression, color-retention, use feeling and spreadability by using Phaffia yeast cells as they are for utilizing the effective content in the Phaffia yeast without damaging. CONSTITUTION: This Phaffia yeast powdery material is obtained by sterilizing the yeast of the genus Phaffia, dispersing the yeast in a distilled water e.g. so as to become <=20 wt.% solid content concentration and spray drying to obtain a raw material having an excellent use feeling without aggregating the cells. A color tone cosmetic composition is obtained by using the obtained yeast of the genus Phaffia powdery material as an active ingredient. As the yeast of the genus Phaffia, Phaffia rhodozyma strain, and astaxanthin-producing mutants,β-carotene-accumulating mutants and white carotenoid-based pigment- producing mutants therof are cited. The content of the yeast of the genus Phaffia powdery material is preferably 0.1-50 wt.% based on the total weight of the color tone cosmetic composition. |
