Abstract

The present invention addresses the problem of providing an oil-based solid cosmetic which, despite being a solid cosmetic, has a feeling of use such as melting, is easy to fade, and has excellent bleed-out stability. [Solution] The oily solid cosmetic contains (A) a high-melting-point wax having a melting point of 75 DEG C or more, (B) a low-melting-point wax having a melting point of 40-70 DEG C, and (C) a powder having a particle size of 1-50 [mu] m, the ratio of the low-melting-point wax (B) to the total amount of the high-melting-point wax (A) and the low-melting-point wax (B) being 20-80 mass%, and the mass ratio of the powder (C) to the low-melting-point wax (B) being 0.7 or more.

Description

technical field [0001] The present invention relates to oily solid cosmetics. Background technique [0002] Solid materials such as wax (ロウ) and wax (ワックス) are generally prescribed for bases of oil-based solid cosmetics such as lipsticks and lip glosses that color the lips, and makeup cosmetics such as blush (cheek) and eye shadows. . The so-called solid material is an essential material for maintaining the solid form of solid cosmetics. However, due to the solid material, there is a problem that it is difficult to obtain a soft feeling of use, luster, and moist feeling. [0003] In view of such problems, for example, Patent Document 1 describes that by blending an ethylene propylene copolymer forming a hydrocarbon wax into an oil-based solid cosmetic, the usability is improved, the gloss is excellent, and the shape retention is further improved. In addition, Patent Document 2 describes that by blending lipophilic sucrose fatty acid esters into solid cosmetics, the ability...
