Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a nail polish, and more particularly to an antibacterial nail polish.

[0002]

[Prior art]

 Conventionally, nail polishers have been used to polish the surface of nails to make them beautiful.

A typical example of a conventional nail polisher is indicated by reference numeral 1 in FIG. The nail polisher of FIG. 1 (A) comprises a base material 4 and a polishing layer 5 and a polishing layer 7 formed on the opposite surface of the polishing material 5 with the base material 4 sandwiched between them. Both end surfaces 2 and 3 are curved surfaces.

FIG. 1B is an enlarged sectional view of FIG. 1A taken along the line aa. On a base material 4 made of a material such as wood, hard paper or plastic, a binder adhesive 10 is kneaded with abrasive grains 9 (a) and a curing agent, and the coated and dried polishing layer 5 is formed. A polishing layer 7 is formed on the opposite surface of the base material 4 with the binder adhesive 10 kneaded with the abrasive grains 9 (b) and a curing agent, and then dried. The abrasive grains 9 (a) and 9 (b) contained in the polishing layers 5 and 7 have different particle diameters, and the polishing layer 5 having the large abrasive grain 9 (a) has The roughened surface 6 is formed on the surface of the polishing layer 7 having the abrasive grains 9 (b) having a small grain size, and the finished surface 8 is formed on the surface thereof.

When the nail polisher 1 shown in FIG. 1 is used, first, the rough surface 6 of the nail polisher 1 is applied to the finger against the nail to be polished, and the nail is made to reciprocate laterally. Next, finish using the opposite finishing surface 8 in the same way.

[0006]

[Problems to be Solved by the Invention] The conventional nail polish has the following problems.

[0007] Conventional nail polishes come into contact with nails and skin, and organic substances such as scraped nails and skin and water adhere to the nail polisher, so that bacteria such as Gram-negative bacteria and Gram-positive bacteria attach and increase. In some cases, fungi grew due to the colonization with fungi such as filamentous fungi. Some of these bacteria and fungi are pathogenic to humans.

On the other hand, since the nail and the skin are almost on the same surface, it is difficult to polish only the nail with a conventional nail polisher. There is a case that the part of is abraded and scratched. Also, since the polishing layer is formed on the surface of the nail polisher, it may inadvertently scratch the skin such as the back of the hand during handling.

Bacteria and fungi adhering to the nail polish may enter the human body through such a wound and may adversely affect the human body. An example of a bacterium that adversely affects the human body is Trichophyton rubrum, but if the toenails are scratched and the toes are scratched while the bacteria are attached to the nail polish, the wounds will be damaged. There is a risk of becoming infected with this bacterium and becoming so-called athlete's foot.

In addition, if molds are formed by fungi such as filamentous fungi, it is apparently unsanitary.

In order to overcome the above-mentioned problems, the antibacterial nail polish according to the present invention has been developed.

[0012]

[Means for Solving the Problems]

 The nail polisher according to the present invention comprises a base material, and a polishing layer formed by kneading and drying abrasive abrasive grains in a binder adhesive on at least a part of the base material. It is characterized by containing antibacterial agent-carrying particles or organic antibacterial agent in the polishing layer without adding it, which has an antibacterial function that bacteria and fungi are less likely to adhere to the nail polisher. Therefore, even if a small scratch is made during the nail polish, there is no risk that bacteria attached to the nail polish will enter the body through the part. Also, there is no risk of mold becoming unsanitary in appearance.

Here, the antibacterial agent of the antibacterial agent-supporting particles is silver or a silver complex, in which case the carrier is silica gel, calcium phosphate, glass, zeolite, zirconia phosphate, Ca / Zn / Al phosphate double salt and At least one of calcium silicate is selected.

The organic antibacterial agent is preferably an organic pyrazolopyrimidine derivative such as dimethylpyrazolylhydroxyphenylpyrimidine.

Further, the nail polisher according to the present invention can have a rough-cut surface and a finish surface, and one nail-polish tool can perform rough-cut and finish. Further, as will be described later, it is possible to identify the roughness of the particles on the polishing surface by applying different coloring to both. If it can be identified, the nail finished with the finished surface is accidentally scraped with the rough surface, and the gloss of the finished surface is damaged, or on the contrary, the first finished surface is mistakenly used, and it takes a long time to polish. There is no fear of spending money.

Further, not only for identification, but also by applying a beautiful color or a pattern on the surface, it is possible to make a nail polish that a consumer can easily select.

Furthermore, in the nail polisher according to the present invention, the roughened surface and the finished surface may have different shapes so that the roughness of the particles on the polished surface can be distinguished. Another advantage of having different shapes for the rough surface and the finished surface is that the other surface can still be used, for example by increasing the surface where abrasive particles wear faster. While it is possible, it is sometimes possible to eliminate the uneconomical situation that the other side becomes worn and unusable. In addition, by increasing the width of the roughing surface that is moved widely, it is possible to shorten the time for roughing work, and by narrowing the width of the finishing surface for fine work, it is easier to perform finer work. You can also do it.

In addition, the nail polish according to the present invention may include a fragrance, thereby enhancing the cleanliness and making it easier for the consumer to select the nail polish.

Further, if the conventional nail polisher is covered with a case made of cloth or vinyl, the air permeability may be poor and the humidity in the case may be high, which may result in an environment in which bacteria are likely to grow. However, since the nail polish of the present invention has an antibacterial function, it is less likely to cause such a problem and can be covered with a case. By covering it with a case, it is possible to prevent scratches from coming into contact with the nail polisher, and to prevent the nail polisher body from being damaged.
