Description

    The present invention relates to a solid powder cosmetic excellent in make-up effects such as glossiness and color rendering effects, and excellent usability.

  In recent years, solid powder cosmetics such as powder foundation have become the mainstay of powder cosmetics because of their excellent portability. The foundation is required to have an effect of hiding troubles such as skin blotches and dullness, and at the same time, it is required to have a so-called “color rendering effect” that gives the skin a so-called “gloss” and makes the skin color brighter and more gorgeous. ing. In order to achieve such a subject, there exists a technique which mix | blends the titanium dioxide coating mica which has glossiness with base makeup materials, such as a foundation (for example, patent document 1, patent document 2, patent document 3). However, in these technologies, the particle size of the interference pearl agent is relatively large and the feeling of close contact with the skin is insufficient. In some cases, the gloss is not sufficiently applied to the skin, or the color rendering effect that brightens the skin by the interference color is not sufficient.

  Further, it is well known to improve the adhesion of powder cosmetics to the skin by containing an oily agent having adhesiveness to powder cosmetics such as foundations. However, when these adhesive oils are blended with solid powder cosmetics, the adhesion between the solid powder cosmetics increases, and the surface becomes hard during use of the solid powder cosmetics, making subsequent use difficult. In some cases, so-called “tekari” occurred.

Accordingly, there has been a demand for solid powder cosmetics that are excellent in usability, such as being excellent in make-up effects such as a color rendering effect that gives gloss or brightens the skin, and does not cause shine even in long-term use.

On the other hand, in solid powder cosmetics, it is quite known that the quality of the final molded product will appear greatly by adjusting the olsen penetration hardness of the solid powder cosmetic by a wet molding method using a volatile solvent. It wasn't. In addition, a solid powder cosmetic compounded with a solubilized oil agent and glossy titanium dioxide-coated mica and molded by a so-called wet molding method is highly effective in providing gloss to the skin, and makes the skin brighter. It has not been known that it is excellent and does not cause a decrease in usability due to the occurrence of light.
