Description

The present invention relates to a powder composition for solid powder cosmetics molded into a variety of three-dimensional shapes such as dome shape, hemispherical shape, conical shape, pyramid shape, diamond cut shape, and the like, and a molded solid powder cosmetic material. In more detail, when molded into a three-dimensional shape, it is excellent in moldability (impact resistance), usability such as the spread and adhesion of the powder during application, and it can be easily applied to the applicator, making caking The present invention relates to a three-dimensional molding powder composition having good usability that does not occur and the obtained solid powder cosmetic.

Conventionally, in solid powder cosmetics, investigations to obtain strength by changing the composition and blending amount of solid oil, semi-solid oil, liquid oil, color pigment, glitter pigment, extender powder, excipient ,
Attempts have been made to produce various sensuality, texture, and color tone, such as studies for improving stability over time.
On the other hand, not only the color tone but also the brand logo is put on the surface of the solid powder cosmetics, or the uneven pattern is given to change the shape of the appearance to further enhance the cosmetic appearance. Such a three-dimensionally molded solid powder cosmetic can be molded using a method of filling a slurry composition with a solvent, drying and molding (for example, see Patent Document 1), or using two types of press heads. A molding method (see, for example, Patent Document 2) has been studied.

However, although the formulation method has been studied, the present situation is that the powder composition for three-dimensional molding is not so much studied. As a technology to increase the impact resistance of conventional flat-shaped solid powder cosmetics, a method of increasing the amount of oil or a method of increasing the amount of excipients such as metal soap has been adopted. In this case, the press pressure on the surface is not evenly applied or the number of corners is increased, which adversely affects the shape retainability where the flat plate shape cannot be predicted, and the production efficiency may decrease. Furthermore, there are problems that caking that causes the cosmetic surface to solidify during use, that it becomes difficult to take off the applicator, and that the spread of spread during application is reduced, and that satisfactory quality is difficult to obtain. It was. In particular, recently, since a lot of pearl agents, lame agents and the like have been used, these tendencies are becoming more prominent.

In addition, by containing a specific oil component, the moldability (impact resistance) can be improved, so use of moldability (impact resistance), removal to the applicator, spread at the time of application, etc. The present inventors have found that a solid powder cosmetic with better properties and usability can be obtained, and have completed the present invention. Furthermore, it has been found that the oil component can be effectively dispersed by blending a specific amount or more of the surface-treated powder, and good moldability can be obtained without blending a large amount of the oil component, The present invention has been completed.
