Description

  The present invention relates to an oily solid cosmetic.

  Conventionally, oily solid cosmetics have been widely used in lip cosmetics such as lipsticks and lip glosses, and in general, the feeling of use at the time of application is required to be uniform and have a good spread. On the other hand, with respect to the finish, the needs have been diversified in recent years, and it has been demanded that the finish should have a matte texture that does not give an unnatural luster.

  For example, as a technique for improving the spread of spread, a technique using a polyethylene wax having an average molecular weight of 500 to 3000, a fatty acid 2-octyldodecanol ester having a freezing point of −10 ° C. or lower, and a pigment (Patent Document 1), a matte texture is improved. As a technique, a technique using a porous inorganic powder, a crosslinked organopolysiloxane, a polymer containing a colored inorganic pigment (Patent Document 2), and the like has been studied.

  However, in the technique of Patent Document 1, a gloss feeling peculiar to oil derived from fatty acid 2-octyldodecanol ester having a freezing point of −10 ° C. or lower was obtained, and a satisfactory matte texture was not obtained. Further, in the technique of Patent Document 2, although a matte texture is obtained, a rough feeling derived from the porous inorganic powder is produced, and a satisfactory expansion and spread cannot be obtained.

  That is, an object of the present invention is to provide an oily solid cosmetic material that has a matte texture and is excellent in stretch spread.

  As a result of earnest research in view of the above circumstances, the present inventors have focused on the fact that kaolinite having irregularities on the surface of the particles causes diffuse reflection of light, and the oily solid cosmetic contains kaolinite. The present inventors have found that a matte texture can be realized when the content is in the range of 15 to 30% by mass. Furthermore, when spherical silica with high transparency and excellent extensibility and dimethylpolysiloxane with an average molecular weight of 500-1500 having a low surface tension and a dry feel are combined, it has a matte texture while being applied. The present invention was completed by finding that an oily solid cosmetic material having a good elongation spread, good color development and excellent stability of drainage can be obtained.
