Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The composition prepared according to the present invention is applied to human nails and dried to protect the surface of the nails smoothly, and at the same time, the applied film fluoresces to give a cosmetic effect. It shows up and falls into the category of cosmetics. The manicure referred to in the present application includes pentig manicure and pedicure. Nail polish is a series of cosmetics that protect your nails by applying them to your nails and make them look beautiful with gloss and colors. The related products are subdivided into nail lacquers, base coats, top coats, nail polish, cuticle creams, removers, etc., and the present invention is applied thereto.

[0002] Nail polish is applied to the nails of the hands, and the case of the nails of the toes is referred to as pedicure. These cosmetic methods have been around for a long time, and are sometimes called general nail enamels because the name gives another bad impression because people of special occupations performed before the war. Also, called false nails,
Other artificial nails are glued on the nails of the limbs as needed, but this is a resin film cut into nail molds and painted on it, and the coloring is also done with nail polish related products Is done.

2. Description of the Related Art In recent years, the degree of makeup has rapidly increased, even for women and some men, in order to improve the sense of beauty, and it is now common sense to apply nail polish to fingernails. Moreover, besides the conventional clear, pink and red-based natural ones,
Rough colors such as black, purple, and silver are also used, or they are extremely diverse such as color coding and pattern writing. In the past, it was a kind of nail polish, but recently, a haze coat that easily adheres to nails, then a color that makes the color flashy, deepens, or writes a pattern, then hardens the surface and scratches Nail makeup is performed in the order of a top coat to prevent sticking, and a nail polish for gloss.

[0004]

Women's insatiable pursuit of makeup is on the left with respect to manicure, and there is a need for new shades that depart from conventional shades. However, coloring pigments have been almost tried, and nothing new has been born. To put it bluntly, for example, in the early days, a nail lacquer base was mixed with a cosmetic tar dye or pigment fine powder, but an interference color was obtained by using a pearl pigment such as surface-deposited mica as a pigment, There are ones that emit a spectral rainbow by using a laminated thin film powder or the like, and those that exhibit pearl luster by a multilayer coating.

[0005]

Means for Solving the Problems The dye which the present inventors have tried to solve this problem is to employ a dye which emits fluorescence upon application (hereinafter referred to as a fluorescent dye). This fluorescent dye emits fluorescence in a dark place, creating a special atmosphere. Since fluorescence is constantly emitted even in a dark place, it is an expected effect that, when used in combination with a conventional dye or pigment, a completely different color effect is exhibited.

As a means for solving the problem, "a film-forming agent dissolved in a solvent, a fluorescent dye and, if necessary, an oil component, a resin component, a plasticizer, a cosolvent, a diluent, Powders, sizing agents, stabilizers, surfactants, acid-alkali agents, coloring dyes, coloring pigments, concealing agents, brighteners, and fragrances.

Here, a general description of nail polish will be given. First, what is called a nail polish base is a mixture of a film forming agent, a resin component, a fat component, and a plasticizer dissolved in a solvent, and is separately prepared in advance of the preparation of the nail polish. The most commonly used film-forming agent is nitrocellulose (hereinafter sometimes abbreviated as NC), and also includes acetylcellulose and cellulose acetate butyrate. NC is obtained by reacting concentrated nitric acid with cellulose such as cotton and pulp. Depending on the degree of the reaction, the nitrification degree at each stage can be obtained.
A value of about 0.5 to 12.0 is appropriate. Since NC is a main raw material, grasping its count is an important matter for quality control in manufacturing.

A resin is often added in order to improve the properties such as flexibility, adhesion and glossiness of the film. Alkyd resin, acrylic resin, methacrylic resin, melamine resin, polyester resin, vinyl resin, styrene resin, maleic acid resin and the like, and modified resins thereof and copolymers thereof. As a natural resin, a dammer, shellac, cyclone, or the like may be used.

Similarly, fats and oils are sometimes blended for the purpose of improving the physical properties such as the removability and repairability of the film and the compatibility of the raw materials. Examples include paraffins, waxes, fatty acids and their glycerides, higher fatty alcohols, carnauba wax, beeswax and silicone waxes. These formulations are also effective in preventing excessive defatting of the skin and nails by the solvent during use.

[0010] Similarly, a plasticizer is added to impart flexibility to the film and prevent cracking and peeling of the film. Dibutyl phthalate, dioctyl phthalate, diisooctyl adipate, acetyl tributyl citrate, dibenzyl sebacate, dicetyl triacetin lactate (DCM) and the like are used. For NC, camphor is used as a unique plasticizer.

Solvents for uniformly dissolving the above materials are important, and the uniform solubility of each material, the drying speed of the coating film, spreadability, smooth finish, feeling of use, smell and the like must be examined. At the time of use, the solvent should evaporate as quickly as possible to form a film. However, after the solvent is obtained, some components are separated and deposited on the way, or blisters that generate latent heat of evaporation occur. For this reason, the solvent is usually mixed with several or more types separately from the true solvent, the co-solvent and the diluent. Also, depending on its boiling point, a low boiling point of 100 ° C. or less: ethyl acetate, methyl formate, dimethyl carbonate, ethyl ether, acetone, methyl ethyl ketone, ethyl alcohol, isopentane,
Cyclopentane, petroleum ether, etc. 100-150 °
Medium boiling point of C: butyl acetate, isobutyl acetate, methyl ethyl ketone, cellosolve, cellosolve acetate, cyclohexanone, furfural, butyl alcohol, amyl alcohol, toluene, solvent naphtha, and the like. 1
High boiling point of 50 to 180 ° C: diacetone alcohol,
Penzyl alcohol, carbitol, butyl lactate, ethyl benzoate, decalin, highly soluble naphtha, pine oil, turpentine oil, etc. Inexpensive lacquer mixed solvents are commercially available. The above-mentioned organic solvents are selected from among them and used for dissolving the substrate.
It is also used as a cosolvent for improving the drying property and finish lubricity of the lacquer, and as a diluent for adjusting the consistency and applicability of the product.

[0012] Basically, the above melt-mixed composition is called a nail lacquer base, which can be used as a clear coat. However, in the case of the base coat and the top coat, the number and composition of the raw materials are slightly different in order to meet the purpose. That is, in the case of the base coat, in order to improve the adhesion of the coating film, NC having a nitrification degree of about 12 is used, the resin content is slightly increased, and the medium boiling point solvent is increased. It is better to use NC having a nitrification degree of about 11 in order to harden the coated surface, to increase the evaporation rate of the solvent and to reduce the Kauri-Butanol coefficient in order to harden the coated surface.

Various color materials are used depending on consumers' desire for manicure. Conventional ones are inorganic pigments, organic pigments,
Organic dyes, metal foils, plastics foils, fish scales, mica flour, and the like. In the present invention, these are coloring materials described collectively as coloring dyes and coloring pigments, and one or more of them are used. These are, of course, color materials that include not only tones such as red, blue and yellow, but also decorative colors such as white and black lightness, spectral colors and interference colors. However, manicure falls under the category of cosmetics under the Pharmaceutical Affairs Law, and therefore the raw materials used in its manufacture were limited to items that had been licensed by the former Ministry of Health and Welfare. However, from this year, it has become the policy of the Ministry of Health, Labor and Welfare to allow the manufacturer to choose freely if safety is confirmed. Therefore, the present inventor searched for a new coloring material having a remarkable effect, and found that a fluorescent dye was extremely effective.

That is, a nail varnish containing a fluorescent dye is:
Fluorescence was emitted in the dark, and it was confirmed that it exerted a special aesthetic effect by multiplying with finger movement. Furthermore, when combined with a conventional color material, a new color with a changed basic color is exhibited even in a dark place.

The fluorescent dye emits fluorescence by a spontaneous emission from a singlet state, and includes a light emission from itself and a light emission from an external stimulus. Further, there are a case where they emit intrinsic fluorescence in a pure state, and a case where they emit fluorescence when a solution in an appropriate solvent or a solution (melted in glass) is formed. Representative examples of the former are CaWO _{3 for} inorganic substances and anthracene for organic substances, and examples of the latter are solutions of fluorescein and rhodamine, and examples thereof include glass in which uranium oxide is co-dissolved.

Organic light-emitting material: polycyclic aromatic anthracene,
Berylene derivatives (helylene, Tafel, trans stilbene, tetraphenylbutadiene, 2,5-phenyloxol, fluorescein, hydroxycoumarin,
4-methoxynastrilenbenzimidazole, 8-quinolinol aluminum complex. ) Etc. Photoluminescence (wavelength conversion functional material): oxadiazole derivatives, rhodamine dyes, coumarin dyes,
Polymethine dyes, etc. These are fluorescent dyes that can be used in the present invention and can be used in their original form, but they are often commercially available in their diluted form, in which case they are trade names and their contents are not disclosed. .

[0017] In addition, the chemicals that may be added as required are one or more of powders, sizing agents, surfactants, stabilizers, acid alkali agents, concealing agents, brighteners, and fragrances. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1. FIG. ~ 4. Table 1. As listed in

[Table 1]

The color tone when these nail varnishes are applied to nails. Embodiment 1 FIG. It is red-red when viewed in the normal direction, but emits a green fluorescent color like alexandrite when viewed diagonally. Embodiment 2. FIG. Although it is a light blue-violet transparent lacquer, it emits blue fluorescent light and is like a Victoria stone in terms of jewelry. The effect is great if a white coat is applied to the base and overlaid. Embodiment 3 FIG. The lacquer containing fish scales and mica is easily adhered to the nails and is easily damaged, so it is better to apply it on this base coat. The product itself is white, but it contains a fluorescent bleaching dye to enhance the whiteness. If you apply another nail lacquer on top of this, you can enjoy another coloring. For example, based on this product, the embodiment 1 When applied with enamel, it looks like a moonstone. If you want a Mexican opal feel, use a black haze coat. Embodiment 4. FIG. A nail polish that forms a hard coat. If a fluorescent dye is also added to the nail polish, in the case of this example, the persistence of fluorescence is maintained by afterglow in a dark place, and a special atmosphere is created. Thus, the product of the present invention can be expected to develop new as a lacquer capable of producing the art of nails by the combination of its application.

There is no concern about the toxicity of nail polish containing a fluorescent dye. The amount is small and the nails are the least affected area for chemical pollution of the human body. Although there are reports of keratinous defatting and inhalation toxicity with solvents and the like, this is the same as with ordinary nail polish.
