Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-layer type nail polish. More specifically, the present invention relates to a two-layer separation type nail polish having good redispersibility of powder, good operability at the time of application, and a beautiful color tone of a film applied to a nail.

[0002]

2. Description of the Related Art Powders such as pigments are blended with nail polish to impart color to nails. Further, plate-like powders such as a pearl agent and a lame agent also have a beautiful pearly feeling and interference color when applied to nails, and thus are incorporated into many nail additives. However, simply blending a pigment or a pearl agent causes all or part of the sediment to settle, and the nail enamel is separated into two layers. For this reason, a thickener is compounded in the ordinary nail enamel to prevent sedimentation of pigments and pearling agents. However, in order to mix a large amount of pigments and pearling agents for a stronger color tone and pearly feeling, it is necessary to further increase the thickening agent to prevent sedimentation, and as a result, the viscosity of the nail polish must be increased. Becomes
There was a drawback that coating became difficult. In addition, there have been many demands for a variety of changes in the pearl color tone of the film applied to the nail with a single nail polish.

[0003] On the other hand, when a two-layer separation type nail polish containing no thickener is prepared, it is necessary to re-disperse the pearl with a stirring ball or the like. It was difficult to redistribute it, and it was not always satisfactory.

[0004]

It can be seen that Examples 1 to 4 of the present invention, in which a large-diameter plate-like powder having a thickness of about 1000 µm was blended, were excellent in redispersibility, operability at the time of application, and beauty of the finish.

On the other hand, Comparative Examples 1 and 2 in which a small pearl agent having an average particle diameter of 50 μm alone or a plate-like powder having an average particle diameter of 80 μm were blended had poor redispersibility and an average particle diameter of 1500 μm.
