Abstract

A novel powder-containing solid cosmetic preparation characterized by comprising as essential ingredients (A) 25-55 mass% elastic-powder mixture, (B) 20-40 mass% powder composed of nonelastic spherical silicone resin particles having an average particle diameter of 0.1-50 [mu]m, and (C) 25-55 mass% oil ingredient, the elastic-powder mixture (A) comprising one or more elastic powders (A1) and one or more composite powders (A2) each obtained by coating an elastic powder with a nonelastic substance. The powder-containing solid cosmetic preparation is obtained by solidifying a mixture composition comprising these essential ingredients. The cosmetic preparation appears transparent and has excellent applicability. It gives a nontacky feeling when applied and gives excellent use feelings including a dry feeling and fresh feeling.

Description

technical field [0001] The present invention relates to a solid powder cosmetic having a transparent appearance, excellent aesthetics, excellent usability such as sticking when using puffs, powder brushes, etc., and improved senses of use such as dryness and refreshment. Background technique [0002] In recent years, various dosage forms of cosmetics having a transparent appearance have been developed for the purpose of adding value such as a beautiful appearance. As such transparent cosmetics, cosmetics mainly composed of water-based components such as lotions and emulsions (for example, refer to Japanese Patent No. A lot of studies have been conducted with reference to JP-A-11-222413). [0003] On the other hand, it is very difficult to apply this clearing technology to powder cosmetics because there is little oil as a binder. Although the applicant of the present application has disclosed an invention of a solid powder cosmetic in Patent No. 3621233, this solid powder c...
