2. Description of the Related Art Conventionally, polyorganosilsesquioxane resin fine particles and silicone rubber particles having rubber elasticity have been known as silicone fine particles. 1-2686
No. 15 and Japanese Patent Publication No. 7-053646 have already been proposed.

[0003]

However, the former cosmetics containing fine particles of polyorganosilsesquioxane resin, although having a high hardness of the fine particles of polyorganosilsesquioxane resin, are soft, It gave a hard feeling of discomfort. In addition, the latter fine particles having rubber elasticity have largely eliminated the disadvantages of the former, but are difficult to handle due to poor fluidity, and have a strong cohesiveness, so that they can be uniformly dispersed in various base materials. There were considerable restrictions on blending it into cosmetics, such as difficulty and poor compatibility with the base material.
