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 on 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 a pigment comprising a polyvalent metal salt of alkylphosphoric acid with a fluorine compound, and a cosmetic material 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, there are problems in cosmetic properties such as elongation on the skin, smoothness, and makeup loss, and above all, makeup loss due to sebum.

In recent years, it has been proposed to treat the powder with a fluorine compound so as 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-mentioned 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 as compared with those before treatment with a fluorine compound in terms of feeling in use.

On the other hand, for the purpose of improving the smoothness, it has been proposed to add a polyvalent metal salt of alkylphosphoric acid (see JP-A-60-248605), but the above water-repellent / oil-repellent powder has been proposed. When a polyvalent metal salt of alkylphosphoric acid is used in combination with the above, there is a problem that the effect of preventing the makeup from being damaged by sebum is reduced. 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 from being damaged by sebum (makeup lasting), and has excellent spreadability on the skin. The object is 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 research aimed at achieving the above object, the present inventors have found that a treatment obtained by surface-treating a pigment composed of a polyvalent metal salt of alkylphosphoric 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 based on the above findings, and provides a water-repellent / oil-repellent cosmetic powder obtained by surface-treating a pigment comprising a polyvalent metal alkylphosphate salt with a fluorine compound. . Further, the present invention is
The present invention also provides a cosmetic containing the water-repellent / oil-repellent cosmetic powder of the present invention.

Examples of the alkylphosphoric acid polyvalent metal salt constituting the cosmetic powder of the present invention include Ca dicetyl phosphate, Ca monolauryl phosphate, Zn monolauryl phosphate, Ba monolauryl phosphate, and dicetyl phosphate. Examples thereof include Zn salt and Ba salt of dicetyl phosphate, and monoalkyl phosphate polyvalent metal salt is preferable.

Since the above-mentioned polyvalent metal salt of alkylphosphoric acid is used as a pigment component of cosmetics, it must be water-insoluble or sparingly soluble. As the above-mentioned polyvalent metal salt of alkylphosphoric acid (powder), for example, those described in JP-A-63-91309 can be used, but they can also be produced in the same manner as a usual metal soap synthesis method. it can.
