Abstract: [Technical problem] To suppress the occurrence of color streaks in a cosmetic comprising two or more kinds of pigments having different average particle diameters.
[Solution] A cosmetic comprises at least two kinds of pigments having different average particle diameters. The cosmetic preparation has a lightness L* defined by CIE 1976 L*a*b* color system of 65 or less. The lightness L* is determined by filling a borosilicate glass container having a shell diameter φ of 35 mm with the cosmetic preparation to a height of 10 mm, and measuring according to an SCI method from the bottom surface of the filled glass container with use of an illuminant C. The cospmetic comprises behenic acid or a derivative thereof, wherein the blending amount is 0.15 to 2% by mass based on the total amount of the cosmetic.
