Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid powder cosmetic, and more particularly, to a method in which good adhesion to props does not occur, caking does not occur, the spreadability is good, and uniform application is possible. The present invention relates to obtaining a solid powder cosmetic which is excellent in usability and a feeling of use such that a cosmetic film on the skin is not powdery, the texture is fine, and an emollient feeling can be imparted to the skin.

[0002]

2. Description of the Related Art Solid powder cosmetics contain a large amount of powder, so that the cosmetic film on the skin looks powdery and the texture looks coarse, and the like, and the oil content of the skin is reduced to powder. Caused skin troubles such as absorption of the skin and drying of the skin. For this reason, solid powder systems have not been favored by people with dry skin or during the dry season. Various methods have been conventionally studied to solve these disadvantages. For example, if a large amount of oil is mixed, the above-mentioned problems can be solved to some extent. However, if the surface is rubbed with an applicator such as a sponge or mat, a phenomenon that the surface becomes hard (generally called caking) occurs, and the coating is thereby performed. There was a problem that cosmetics could not be transferred to the tool. In addition, the tendency of this caking increased when water was used in the applicator. In addition, caking caused by excess oil is prevented by blending powder with high oil absorption, a method of treating oil on the surface of the powder, and emollient by blending silicone oil or fluorine-based oil in oil. There is a method of imparting a feeling, a method of mixing a powder treated with a fluorine compound with the powder, and preventing caking.

[0003]

However, those containing a large amount of the above-mentioned oils have a high emollient feeling, but have poor adhesion to props, cause caking, spread poorly, and have a poor spread on the skin. There was a problem that it could not be applied to the surface. In addition, the combination of excess oil and powder with high oil absorption at the same time has the disadvantage that the emollient feeling and the feeling of adhesion to the skin are not sufficient, and the decorative film is powdery and the texture is rough. Had. The method of treating the powder with the oil agent and the addition of silicone oil or fluorine oil as the oil agent alone increased the feeling of adhesion to the skin and the emollient feeling, but did not satisfy the removal and expansion of props. . When a powder containing a fluorine-based compound was blended as a powder, there was an effect of preventing caking because it did not wet with other oils, etc., but in a system containing a large amount of oil to enhance the emollient feeling, caking was completely prevented. Could not.

[0004]

Means for Solving the Problems The present inventors have made intensive studies in the above circumstances, and as a result, have found that a fluorinated oil and a partially crosslinked polyether-modified organopolysiloxane polymer and / or a partially crosslinked organopolysiloxane are obtained. If it contains a polymer, it has good removal to props, does not cause caking, has good spreadability and can be uniformly applied, and has a cosmetic film that is not powdery on the skin and has a texture. The present inventors have found that a solid powder cosmetic preparation having an excellent feeling upon use, such as being capable of imparting an emollient feeling to the skin with a fine finish, has been obtained, thereby completing the present invention. That is, the present invention relates to a component (a) a fluorinated oil agent and a component (b) a partially crosslinked polyether-modified organopolysiloxane polymer and / or
