Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nail pill, and more particularly to a nail pill having good stability over time, good usability, and excellent cosmetic effect and long-lasting effect.

[0002]

2. Description of the Related Art Nail preparations are cosmetics that can be applied to nails to impart color or change texture. Conventionally, in the case of a beautiful nail material, an organically modified clay mineral or silicic anhydride has been used in order to maintain the stability of the system.
In addition, various types of coloring pigments such as inorganic pigments such as tar pigments, black iron oxide, carbon black, red iron oxide, and ultramarine blue have been used to realize a wide range of color tones.

[0003]

However, black pigments, such as black iron oxide, which are blended in the nail polish have poor pigment dispersibility, and depending on the system, may cause abnormal color tone due to pigment aggregation or poor dispersion, It is difficult to secure stability such as sedimentation. In addition, for example, carbon black has a problem that gelation is promoted with the passage of time depending on the amount of the oil absorbed due to the amount of oil absorption, and the usability is deteriorated.

[0004]

Under these circumstances, the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that, in the case of a nail preparation containing a film-forming agent and a solvent, component (a) anhydrous By using a specific amount of silicic acid and component (b) titanium / titanium oxide sintered product, the stability with time is good,
In addition, the present inventors have found a beautiful nail preparation which has good usability, and is excellent in cosmetic effect and persistence, and has led to the development of the present invention. That is, the present invention relates to a nail pill containing a film forming agent and a solvent, wherein component (a) silicic anhydride is 0.1 to 10% by mass (hereinafter simply referred to as "%"), and component (b) titanium. The present invention provides a beautiful nail material characterized by containing 0.1 to 10% of a titanium oxide sintered product.
