Description

  The present invention relates to a powder solid cosmetic using a specific powder, having a smooth and smooth feeling of use and usability, and having excellent appearance quality.

  As a molding method for powder makeup products such as foundations, eye shadows, and blushers, compression molding methods are generally used to obtain a predetermined shape by compressing a cosmetic base with a press mold. In view of a high degree of freedom such as a multi-color press, an increasing number of cases use a wet molding method in which a cosmetic base is mixed with a solvent and the solvent is removed after filling.

In addition, as a technology related to the present invention, a powder solid cosmetic that can be used wet while mixing a large amount of spherical powder by a wet molding method using a combination of specific powders such as dehydrated silicate clay mineral (For example, refer to Patent Document 1).
JP2002-241230

  However, solid powder cosmetics containing this powder have the drawback of being slippery and smooth. Also, in the case of the compression molding method for make-up products, if a large amount of powder that is smooth and smooth is blended, it will be overtightened and the so-called caking phenomenon will occur, and the compression will be sufficient. Otherwise, problems may occur in physical properties such as a drop in drop strength. Further, in the wet molding method, there is a problem that cracks are generated at the time of solvent removal or a gap between the container and the appearance is deteriorated. An object of the present invention is to solve such a conventional problem and provide a powder solid cosmetic satisfying both appearance quality and usability.

  As a result of diligent research to solve the above-mentioned problems, the present inventor has blended acryl silicone-treated powder, spherical powder, and synthetic phlogopite to provide a powder solid that has a good feeling and usability and satisfies the appearance quality. The present inventors have found that a mold cosmetic is provided, and have completed the present invention.
