Abstract: Provided is a composition solidified using a solidifying agent that is dissolved in a single-phase composition, which has been obtained by making a moisturizer with an expected moisturizing effect compatible with an oil phase having an occlusion effect.
A solid composition comprising: an oily liquid medium that separates when mixed with water at 1:1; an aqueous liquid medium that is an organic liquid medium other than water, that forms a homogeneous phase when mixed with water at 1:1, and that forms a homogeneous phase when mixed with the oily liquid medium; and an aqueous solidifying agent that is soluble in the aqueous liquid medium and that gels and/or solidifies the aqueous liquid medium, and/or an oily solidifying agent that is soluble in the oily liquid medium and that gels and/or solidifies the oily liquid medium, wherein the oily liquid medium and aqueous liquid medium are gelled and/or solidified with the aqueous solidifying agent and/or oily solidifying agent, and the total amount of the aqueous liquid medium, oily liquid medium, aqueous solidifying agent, and oily solidifying agent is 90% by mass or more of the amount of the composition excluding powder.

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.
