Description

  The present invention relates to a beautiful nail material having a novel appearance and a cosmetic effect, and more specifically, has an appearance with high chroma and glitter, and a cosmetic film formed at the application site has high chroma, The present invention relates to a beauty nail material which can impart unprecedented cosmetic effects such as a sense of transparency, a three-dimensional effect, and a glossy feeling to the nail by optically changing the texture of the application site, and also has good stability.

  Beauty nail is one of the point makeup products that require a wide range of colors. Conventionally, coloring agents such as organic pigments and inorganic pigments, and glittering powders such as pearls and lamés have been widely used and formulated in this nail polish. Therefore, techniques for blending into cosmetics are being studied. For example, coloring with a technique for blending hologram glitter that can provide a three-dimensional gloss effect due to the uneven shape of the surface (see, for example, Patent Document 1), or a high-saturation colorant that obtains an unprecedented high-saturation cosmetic film, and the surface A technique (for example, see Patent Document 2) for blending treated fibers is known. On the other hand, a beautiful nail material blended with short fibers for the purpose of reinforcing the nail has also been studied (see Patent Document 3, for example).

  However, when these pearls and lamés are blended, a unique brightness can be obtained, but there are drawbacks such as the precipitation of the colorant at the time of standing, and the loss of transparency by increasing the blending amount. It was. In addition, when conventional fibers are used for the purpose of reinforcing nails, an effect of preventing two nails can be obtained, but it cannot be said to be a colorant that improves the aesthetic appearance.

  Therefore, not only high saturation but also new materials that can optically change the texture of the application site have been found, and this has been used to create cosmetic effects such as unprecedented transparency, three-dimensionality and gloss. Development of a beautiful nail material that can be applied to the skin is required, and it is an object of the present invention to provide such a beautiful nail material.

  As a result of diligent research to solve the above-mentioned problems, the present inventors have laminated two or more kinds of polymer compounds having different refractive indexes and have colored interference light, a film-forming agent and a non-fragrance. By using a group-based solvent, the appearance is a high-saturation appearance with a new texture with excellent luster, and when used, the nail that is the application site is given high saturation and the texture is optical The beauty of the nail polish has a new cosmetic effect and has good stability. As a result, the present invention has been completed.

As described above, the beauty nail material of the present invention comprises: (A) a colored interference fiber containing two or more kinds of polymer compounds having different refractive indexes; (B) a film-forming agent; and (C) a non-aromatic solvent. Contains ingredients.

  Among the above components, the colored interference fibers (hereinafter referred to as “colored interference fibers”) that are two or more kinds of polymer compounds having different refractive indexes, which are the component (A), are at least two kinds of high A fiber in which a composite fiber having a layered cross-sectional structure (laminated cross section) composed of molecular compounds is colored with a colorant, and this composite fiber exhibits red, yellow, green, blue, purple, etc. as interference colors It is. As for the cross-sectional shape, the flat cross-section interference fiber in which the parallel laminated portion is sandwiched by the protective layer is preferable as it is easily attached to the nail or the like as a cosmetic and more strongly develops color from one direction. The polymer compound used in the colored interference fiber is not particularly limited as long as it is usually used in cosmetics. Examples thereof include nylon, polyethylene terephthalate, polypropylene, polycarbonate, polymethyl methacrylate, and polyester. . Among these polymer compounds, a combination of polyethylene terephthalate and nylon is preferable because it strongly exhibits interference light and has good fiber process stability, and the effects of the present invention appear more remarkably.

  As a coloring agent used for manufacture of the said (A) component, if normally used for cosmetics, it will not restrict | limit, Any thing can be used. For example, Red No. 2, Red No. 3, Red No. 102, Red No. 104 (1), Red No. 105 (1), Red No. 106, Yellow No. 4, Yellow No. 5, Green No. 3, Blue No. 1, Blue No. 2 No., Red 201, Red 213, Red 214, Red 215, Red 227, Red 230 (1), Red 230 (2), Red 231, Red 232, Orange 205, Orange 207 No., Yellow 203, Green 201, Green 204, Green 205, Blue 202, Blue 203, Blue 205, Brown 201, Red 401, Red 502, Red 503, Red 504 Red 506, orange 402, yellow 402, yellow 403 (1), yellow 406, yellow 407, green 401, green 402, purple 401, black 401, etc. Dye, red 202, Color 218, Red 223, Red 226, Red 228, Orange 201, Yellow 201, Yellow 205, Blue 201, Blue 204, Purple 201, Red 404, Red 405, Orange 401 No., yellow 401, yellow 404, yellow 405, blue 403, blue 404, etc. Examples thereof include dyes, acidic dyes, basic dyes, and disperse dyes.
