Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a novel nail beauty product. More specifically, the present invention relates to a nail polish containing organically modified montmorillonite, silica, and a non-aromatic solvent.

That is, the present invention relates to a nail beauty product that is safe for the human body, does not cause sedimentation of pigments or burl agents, has excellent stability over time, and has good coating film properties and usability.

[Prior Art] Conventionally, organically modified montmorillonite has been blended into nail care preparations to utilize its good thixotropy properties derived from clay minerals to prevent pigments and varnish from settling. In this case, toluene as a solvent,
Aromatic hydrocarbon solvents such as xylene have been used. Aromatic hydrocarbon solvents such as toluene swell the clay and form the best gels, and nail polishes containing such gels exhibit relatively good dispersion stability and do not settle or split over time. For this reason, toluene and the like were considered indispensable as solvents for this type of nail polish.

There is also an example (Japanese Unexamined Patent Publication No. 174003/1983) in which hydrophobic silica was added to further improve dispersion stability and stability over time.
These use gel compositions that require toluene, so
Naturally, nail polishes also contain toluene. On the other hand, there is an example (Japanese Patent Publication No. 31-001044) in which a hydroxyl group-containing polar substance and a phenyl group-containing organosilicon compound are specifically blended as a nail beauty gel composition that does not contain aromatic hydrocarbon solvents such as toluene and xylene. The technology for safe nail polish has been established.

[The problem that the invention is trying to solve MJ Aromatic hydrocarbon solvents such as toluene and xylene have been reported to be safe for the human body, and they can damage and make nails especially if you use nail polish frequently. Known to be of concern. In addition, Japanese Patent Publication No. 61-001044, which does not contain toluene, xylene, etc., is safe for the human body and has thixotropic properties, and has somewhat good dispersion stability and stability over time, but in terms of stability it is even worse. There was still room for improvement.

In view of these circumstances, the present inventors have developed a coating film that is safe for the human body, has excellent dispersion stability, and stability over time, and has excellent coating film properties.
As a result of intensive research to develop a nail polish that is easy to use, we have developed a nail polish that is safe for the human body, contains organically modified montmorillonite, silica, and a non-aromatic solvent, and does not cause the settling of pigments or pearlescent agents. , has excellent stability over time, and has good coating film properties.
We have discovered a nail beauty product with good usability and completed the present invention.

[Means for Solving the Problems] That is, the present invention provides a nail polish that essentially contains organically modified montmorillonite, silica, and a non-aromatic solvent. Aromatic hydrocarbon if agents such as toluene and xylene, phenyl group-containing organic silicones, and the like that have been used so far are substances that swell the clay and impart thixotropic properties. However, the present invention does not use toluene, xylene, etc. at all, uses a non-aromatic solvent that is safe for the human body, and provides excellent thixotrivy properties through the interaction of organically modified montmorillonite and silica, achieving a major objective. There is.

The configuration of the present invention will be described below.

The organically modified montmorillonite used in the present invention is a substance in which a quaternary ammonium salt type cation activator and a nonionic higher organic polar compound are chemically bonded to montmorillonite, which is a clay mineral, and is a commercially available product. For example, Benton (Benton 27 manufactured by National Red Co., Ltd.)
Bentone 34, Bentone 38, etc.), any of which can be used. These can be arbitrarily selected as required, and one or more types can be blended. The preferred amount of these components is 0.2 to 3.0% by weight, more preferably 0.2 to 2.0% by weight. If it is less than 0.2% by weight, good thixotropy cannot be obtained;
When you look at the weight percentage, does it affect the gloss and age of the nail polish coating? 3
(Peeling) gets worse.

The silica used in the present invention may be well-known, for example,
Commercially available products include Aerosil #200 and Aerosil #30.
0, Aerosil #380, or Aerosil R972. Among these, Aerosil IT 200,
The particle size of Aerosil #300, Aerosil R972, etc. is 0.
．． It is preferable to have a particle diameter of less than 0.01 μm from the viewpoint of thixotropy.

The preferred amount of these components is 0.1 to 2.0% by weight, more preferably 0.5 to 1.5% by weight.

If it is less than 0.1% by weight, good thixotropy will not be obtained and stability over time will deteriorate. If it exceeds 2.0% by weight, the enamel coating will have poor gloss and poor durability over time.

The non-aromatic solvent used in the present invention broadly refers to organic solvents other than aromatic hydrocarbons such as toluene and xylene, such as n-butyl acetate, isobutyl acetate, ethyl acetate,
Examples include methyl ethyl ketone, acetone, n-butanol, isopropyl alcohol, and ethyl alcohol. One or more of these solvents can be blended. The preferred amount of these components is 60 to 85% by weight.

Furthermore, in addition to the above-mentioned essential ingredients, the nail beauty preparation of the present invention contains film-forming agents, resins, plasticizers, pigments, pearlescent agents, etc. that are usually used in nail beauty preparations, and also contains ultraviolet absorbers, humectants, It is difficult to mix drugs, fragrances, and water in appropriate amounts. Of course, these must be used under qualitative and quantitative conditions that do not impair the purpose of the present invention.

[Effects of the Invention] The present invention relates to a nail beauty product that is safe for the human body, does not cause sedimentation of pigments or pearlescent agents (has excellent stability over time, and has good coating film properties and usability. Compared to aromatic hydrocarbon solvents such as toluene and xylene, they are safer for the human body, cause very little damage or pain to nails, and have superior durability over time. Beautiful nail fx that does not contain aromatic hydrocarbon solvents
Compared to I, the precipitation of Burr agent, stability over time, physical properties of coating film,
The quality is even better in terms of usability.

[Examples] Hereinafter, the present invention will be explained in detail with reference to Examples, and the blending amounts are expressed in % by weight.
