Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a composite powder composed of different kinds of organopolysiloxanes and a partially crosslinked organopolysiloxane polymer, which provides a smooth and excellent spreadability and a refreshing feeling. The present invention relates to a cosmetic product that has a long lasting feeling, has a long lasting makeup, is excellent in persistence of makeup, and is excellent in usability.

[0002]

2. Description of the Related Art In recent years, silicone oil has been widely used as an oil agent in cosmetics in order to make it less sticky and to improve the long-lasting makeup. However, since silicone oil has poor compatibility with other cosmetic oils and does not have a yield value as a flow characteristic, there is a problem that it is difficult to mix substances having a specific gravity difference such as pigment. Therefore, by mixing a partially crosslinked organopolysiloxane polymer and silicone oil, a gel composition having excellent softness and stability can be obtained.
It has been proposed that the incorporation of this compound improves stability and usability (JP-A-1-190575, JP-A-1-250306, etc.).

[0003]

However, if the partially crosslinked organopolysiloxane polymer is blended in a large amount for the purpose of improving the stability and for improving the refreshing feeling and the durability of the makeup, the soft touch is lost. The spread was poor, and the feeling of use was not completely satisfied. On the other hand, in order to improve the usability, it has been proposed to mix fine particles of polyorganosilsesquioxane resin or fine particles of silicone such as silicone rubber powder having rubber elasticity in cosmetics (Japanese Patent Application Laid-Open No. HEI 1-1990). -268615
And Japanese Patent Publication No. 7-053646. However, the former, in which fine particles of polyorganosilsesquioxane resin are blended, has a high hardness of the fine particles of polyorganosilsesquioxane resin, but gives a sense of incongruity of a hard touch, though it is dry. Was. In addition, the latter fine particles having rubber elasticity, although the disadvantages of the former are largely solved, are difficult to handle due to poor fluidity and strong cohesiveness, so that it is difficult to uniformly disperse them in various base materials. There were considerable restrictions on blending into cosmetics, such as poor compatibility with the base material. Therefore, good usability,
There has been a demand for the development of cosmetics which are excellent in usability and stability over time, and which are satisfactory in terms of long-lasting makeup and long-lasting makeup.

[0004]
