Description

The present invention relates to an oil-based solid cosmetic having a smooth feeling of use and excellent cosmetic durability.

In recent years, oil-based solid cosmetics such as lipsticks are required to have various effects other than the cosmetic effect of imparting color to the lips. For example, improvement and improvement of usability such as smooth wearing comfort are required. On the other hand, since the lips are three-dimensional and violently moving parts, there is a problem that the cosmetic film is liable to collapse because it cannot respond to the movement of the lips. As a result, if the adhesive force to the lips is increased (see, for example, Patent Document 1), the feeling of use becomes heavier, and the makeup lasting due to the secondary adhesiveness due to the transfer to the part in contact with the lips such as the cup has been a problem. .. In addition, technologies that increase the adhesive force and enhance the makeup retention by blending an oil-soluble resin (see, for example, Patent Document 2) have poor followability of the makeup film to the movement of the lips, resulting in a feeling of film. There was a problem that the film was torn and became non-uniform.

On the other hand, 0.1 to 0.8% by weight of wax and hydrophobic treatment fumed silicic anhydride having a linear or branched _C 10 _{-C 22} fatty chains of 65 ° C. hereinafter mp 30 ° C. or higher and a melting point It has not been known that an oil-based solid cosmetic containing a wax having a melting point of 75 ° C. or higher achieves both smooth wearing comfort, followability of a cosmetic film, and cosmetic durability.
