Abstract: A method for producing a powder solid composition including a base containing non-volatile liquid oil, the method includes: blending wax in a powder form into the base; dispersing the base in a solvent; volatilizing the solvent at a first temperature where the wax does not dissolve; and heating the base at a second temperature where the wax dissolves, wherein a blending amount of the non-volatile liquid oil is 15% by mass or more and 40% by mass or less with respect to the base.

Abstract: The purpose of the present invention is to provide a novel transparent oil-based cosmetic product which, when decorating the transparent oil-based cosmetic product, enables decoration with a variety of designs using a cosmetic ingredient, and which also enables decoration in a simplified method using a printing technique or the like. The present invention pertains to an oil-based solid cosmetic product which has a transparent oil-based base (A) and at least one decorative layer (B), and which is characterized in that: the transparent oil-based base (A) contains a thickener (a1) and a liquid oil (a2); the decorative layer (B) contains a powder component (b1); and the powder component (b1) contains at least one type of powder that has a higher refractive index than that of the liquid oil (a2).

Abstract: An oil based composition having a smooth sensation of use, which exhibits a superior unevenness correcting effect, and which may be filled in a container which is not airtight, is provided. An oil based composition includes, with respect to 100% by mass of the oil based composition: (a) 1 to 20% by mass of a dextrin fatty acid ester; (b) less than 5% by mass of a volatile oil component having a boiling point of less than or equal to 250° C. at normal pressure; (c) 10 to 60% by mass of a non volatile oil which is a liquid at normal temperature and normal pressure; and (d) 10 to 50% by mass of a silicone resin powder.
