[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a make-up base and a make-up method which have a long-lasting effect on makeup and are less likely to be twisted or broken. More specifically, the present invention relates to a makeup base material containing a tacky, fluorine-modified silicone resin having a silanol group in the molecule, and a makeup method excellent in durability of makeup effect.

2. Description of the Related Art Conventionally, the problems to be solved by the invention
As can be seen from Japanese Patent Application Laid-Open No. 1-242512, it is known that blending a resin dissolved in a volatile solvent into a makeup base or overcoat cosmetic improves the durability of the makeup effect.

[0003] However, since the resin conventionally used in cosmetics dissolves in squalene, which is the center of the sebum component, the durability is greatly improved as compared with the case where no resin is blended, but in the summer Under conditions where a large amount of sweat or sebum is secreted, etc., the sustainability was often insufficient. In addition, materials with weak adhesion among resins cannot hold powder sufficiently, and under the severe conditions of summer,
In many cases, sustainability was not sufficient.

In view of these problems, as a result of intensive studies by the present inventors, fluorine having a silanol group in the molecule, which is a compound having a property of being highly adherent while having oil resistance not dissolving in squalane. By developing a modified silicone resin (hereinafter referred to as FQ resin) and incorporating it into a makeup base material, the powder in the powder cosmetic material is strongly fixed to the skin, causing a phenomenon such as makeup breakdown and wrinkling. It has been found that a makeup base material and a makeup method, which are difficult to increase the durability of the makeup effect, can be obtained.
