Description

Detailed Description of the Invention

[0001]

The present invention has excellent water and oil repellency,
The present invention relates to a water-repellent / oil-repellent cosmetic powder which does not break down in makeup, has good spreadability on the skin, and has a good feeling in use, and a cosmetic material containing the powder. More specifically, it relates to a water-repellent / oil-repellent cosmetic powder obtained by surface-treating an amidesulfonic acid polyvalent metal salt with a fluorine compound, and a cosmetic containing the powder.

[0002]

2. Description of the Related Art Cosmetics containing cosmetic powders include makeup cosmetics such as foundation, white powder, blusher, eye shadow, eyebrow, body powders and baby powders. Cosmetics are commercially available. In cosmetics containing these cosmetic powders, cosmetic properties such as elongation on the skin, smoothness, and makeup loss, especially makeup loss due to sebum are problems.

In recent years, it has been proposed to treat the powder with a fluorine compound to impart water repellency and oil repellency to the powder for the purpose of preventing the makeup from being damaged by the sebum of the above cosmetics (Japanese Patent Application Laid-Open No. 2000-242242). JP-A-55-167209, JP-A-62-250074
No. 1-180811 and U.S. Pat. No. 3,632,744). However, these water-repellent / oil-repellent powders have a drawback that they are extremely inferior in smoothness in terms of feeling in use as compared with those before treatment with a fluorine compound.

On the other hand, for the purpose of improving smoothness, it has been proposed to blend a polyvalent metal salt of amide sulfonic acid (see Japanese Patent Laid-Open No. 3-294210), but the above-mentioned water repellency
There is a problem in that the effect of preventing the makeup from being damaged by sebum is lowered when the oil-repellent powder is used in combination with a polyvalent metal salt of amide sulfonic acid. Therefore, the object of the present invention is to provide excellent water and oil repellency, and also a feeling of use, especially smoothness.
Oil-repellent cosmetic powder, and containing the powder, has good water resistance, sebum resistance, and oil resistance, has an excellent effect of preventing makeup deterioration due to sebum and the like (makeup lasting), and spreads on the skin. It is intended to provide a cosmetic composition which is good and has a feeling in use, and particularly excellent in smoothness.

[0005]

Means for Solving the Problems As a result of intensive studies to achieve the above object, the present inventors have found that a treatment obtained by surface-treating a pigment composed of a polyvalent metal salt of amidosulfonic acid with a fluorine compound. It was found that the powder and the cosmetic containing the treated powder have excellent smoothness and excellent water and oil repellency. The present invention has been made on the basis of the above findings, and the amide sulfonic acid polyvalent metal salt represented by the following general formula (I) represented by the general formula (I) is surface-treated with a fluorine compound. A treated water-repellent / oil-repellent powder for cosmetics is provided.

(Evaluation method of water repellency) About 0.05 g of each powder
15 ml of water was put in a beaker for 30 ml and floated, and the beaker was shaken to observe the dispersibility of the powder in water and squalane. The evaluation was based on the following criteria. 0: The powder was dispersed in water and squalane. 1: When the beaker was shaken, the powder was almost dispersed within 30 seconds. 2: After shaking the beaker, the water became cloudy after 1 minute, but some powder floated on the water. 3: After shaking the beaker, the water became cloudy after 1 minute, but many powders floated on the water. 4: When the beaker was shaken, the water did not turn cloudy after 1 minute, and no powder dispersed in water was observed. Even if the beaker was shaken for 5 minutes or longer, no powder dispersed in water or squalane was observed.

(Evaluation Method of Oil Repellency) Evaluation was carried out in the same manner as in the evaluation method of water repellency except that squalane was placed in a beaker for 30 ml instead of water.

(Evaluation Method for Feeling in Use) Five expert panelists evaluated the feel of the powder on the basis of the following five grades from 1 to 5 from the smoothness, squeaky feeling, and roughness of the powder. Shown by value. 1: The feeling of smoothness is poor. 2: The feeling of smoothness is a little bad. 3: Normal. 4: Feeling such as smoothness is slightly good. 5: Good feeling such as smoothness.
