Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin external preparation containing an aqueous component, which has improved usability such as moist feeling, dry feeling, refreshing feeling, and good spreadability. Things.

[0002]

2. Description of the Related Art Conventionally, an aqueous component has been blended into an external preparation for skin to impart a moist feeling and a moisturizing property. However, while a moist feeling and a moisturizing property are imparted, stickyness occurs, and in some cases, the feeling of smoothness and spreading is poor.
In order to improve the usability and usability, a volatile solvent is compounded, or a powder such as silica or silicone resin powder is compounded, and various methods have been studied. No usability has been obtained.

[0003]

As the silicone resin powder, fine particles of polyorganosilsesquioxane resin,
Silicone rubber particles having rubber elasticity are known, and blending them into cosmetics has already been proposed in, for example, JP-A-1-268615 and JP-B-7-053646. However, the cosmetics containing the fine particles of the polyorganosilsesquioxane resin of the former have a high hardness of the fine particles of the polyorganosilsesquioxane resin, but although they are dry, they give an uncomfortable feeling of a hard touch. Was. On the other hand, the latter fine particles having rubber elasticity have largely eliminated the disadvantages of the former,
Due to poor fluidity, it was difficult to handle, and because of its strong cohesiveness, there were considerable restrictions on blending it into cosmetics, such as difficulty in uniform dispersion on various substrates and poor compatibility with the substrate. . Therefore, there has been a demand for the development of an external preparation for skin that has a moist feeling, a dry feeling, a refreshing feeling, and a usability such as good spreadability.

[0004]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, using a composite powder composed of different organopolysiloxanes as an external preparation for skin containing an aqueous component.
