DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cosmetics, and more particularly, to cosmetics having a smooth growth, being excellent in contact with and familiar to the skin, resistant to sweat and water, and excellent in keeping makeup.

[0002]

[Prior Art] Foundation, tofu, blush,
Cosmetics such as eye shadow have a smooth growth,
It is required that it has excellent skin adhesion and familiarity, is resistant to sweat and water, and has excellent makeup durability.

[0003] In order to improve the performance of the above-mentioned growth, adhesion to the skin, and adaptability, a suitable one is selected from clay minerals such as mica, talc, sericite, and kaolin, which are generally used as extender pigments. It is common practice to consider the compounding of the compound.

[0004]

However, the performances such as stretching and sticking to the skin are originally contradictory, and even if the selection of the clay mineral is optimally performed,
There was a limit to the performance of the resulting cosmetics.

[0005] In addition, since the clay mineral generally shows hydrophilicity, it is necessary to perform a hydrophobic treatment on the mineral in order to be resistant to sweat and water and to improve the durability of the makeup. However, depending on the silicone treatment, metal soap treatment, and the like, which are generally performed, when an attempt is made to impart sufficient hydrophobicity,
It often has an adverse effect on the feeling of use, such as spreading and familiarity with the skin, which has been a problem.

[0006] Therefore, in the past, it was difficult to spread and adhere to the skin.
In a situation where it is difficult to obtain a cosmetic which is excellent in familiarity and the like, and which is resistant to sweat and water and has a long lasting makeup, it has been desired to solve the above problems promptly.

[0007]

Means for Solving the Problems The present inventors have conducted intensive studies in view of the above-mentioned circumstances, and as a result, by blending cosmetic powder comprising an organic derivative of zirconium phosphate into cosmetics, it has been found to be effective for spreading and skin. The present inventors have found that a product which is excellent in stickiness and familiarity, and which is resistant to sweat and water and excellent in keeping makeup can be obtained, and has completed the present invention.

That is, the present invention provides a compound represented by the general formula (1)
