DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdered cosmetic composition having an excellent feel upon use.

[0002]

2. Description of the Related Art Powdered cosmetics are used to clean skin by adsorbing dirt on the skin and excess sebum and sweat to the powder. It is widely used for the purpose of enhancing the cosmetic durability and improving the feeling of use by utilizing the smooth touch.

For example, as a lotion, calamine (0.
There is a lotion containing zinc oxide containing about 5% ferric oxide, which is widely used as a summer lotion having a drying, cooling and protective action.

[0004]

However, since the above-mentioned powder-containing cosmetics are basically intended for moisturizing or astringent, their feeling of use has not been considered much. In the case of emulsified cosmetics containing powder,
Since a large amount of powder could not be blended due to emulsification balance, it was not sufficient to give a dry feeling and was not satisfactory.

[0005] On the other hand, baby powder and talcum powder are known as body powder cosmetics that are used for the whole body after a summer bath or after shaving to give a soft feeling to the skin and to absorb sweat and moisture. Have been. Also, dusting powders for blending fragrances into powders are known.

[0006] However, these powdered body powder cosmetics to be used after powdering are inconvenient in terms of usability such as scattering of powder and soiling of clothes and peripheral parts.
Further, after powdering, there was a problem that the powder remained white.

The inventors of the present invention have made intensive studies in view of the above-mentioned problems. As a result, when a cosmetic is blended with a polyoxyethylene dicarboxylic acid ester, an alkyl-modified carboxyvinyl polymer, and a powder, the feeling of use, particularly the smoothness, is improved. The present invention has been found to provide a cosmetic composition which has excellent stickiness, has no sticky feeling, and inconspicuous whiteness of the powder after use, and has completed the present invention.

[0008] An object of the present invention is to provide a powdered cosmetic composition which is excellent in use feel, particularly smoothness, has no sticky feeling, and in which the whiteness of the powder after use is not conspicuous.

[0009]

That is, the present invention provides a cosmetic containing a polyoxyethylene dicarboxylic acid ester represented by the following chemical formula (1), an alkyl-modified carboxyvinyl polymer, and a powder. .

Embedded image (1) (wherein, R 1 and R 2 are hydrogen or an alkyl or branched alkyl group having 1 to 4 carbon atoms, and m, n, X and Y are 0 to 5
Do not become 0 at the same time. R3 has 0 to 10 carbon atoms
