Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an extremely useful nail beauty preparation, and more specifically, to a nail beauty preparation containing nitrocellulose as a film-forming agent as a main component. The present invention relates to a nail polish that has a coating film with significantly less gloss than other nail polishes, and has good film properties, usability, and stability over time.

[Prior Art] Nail beauty products that have been commonly used in the past have nitrocellulose as a film-forming agent as a main component, and this type of nail beauty product has one of the important qualities of nail beauty products. It has excellent film-forming properties, gives gloss to the coating film, is easy to apply to the nail surface, and has good stability over time.

However, in recent years, consumer demands for cosmetics have diversified, and nail beauty products with suppressed gloss are also desired.

From this point of view, the average particle size of 0, OI ~
A technology has been proposed that suppresses the gloss of the paint film and gives it a matte feel by blending 30 l of silica (Japanese Patent Laid-Open No. 8
0-1 [1910 publication].

[Problems to be Solved by the Invention] As mentioned above, in the past, it has been an important quality requirement for nail cosmetics that the coating film has gloss, and that It has also been common practice to increase gloss by combining other components such as resins.

Therefore, on the contrary, there have been few attempts to suppress the gloss of coating films, and there are only a few examples mentioned above, and the reality is that they have not been studied in detail.

[Means for Solving the Problems] In view of the above, the present inventors have developed film properties, usability, and
As a result of intensive research in order to obtain a nail polish that suppresses the gloss of the paint film without impairing its stability over time, it was discovered that by incorporating nylon powder, a remarkable gloss suppressing effect can be obtained.1 The present invention was developed. It has been completed.

That is, the present invention is characterized in that nylon powder is blended in an amount of 1 to 10% by weight in a nail beauty product whose main component is nitrocellulose as a film-forming agent.

In addition to nail enamel, the nail beauty agent used in the present invention includes base coats used to improve the adhesion and durability of nail enamel, and top coats used to strengthen the nail enamel film. It is something that

The nitrocellulose that is the main component in the nail beauty product according to the present invention may be any conventionally used and well-known nitrocellulose, such as nitrocellulose nitrocellulose, nitrocellulose %, etc., and one or two of these may be used. The above is blended. The blending amount is usually used in the range of 5 to 20% by weight.

In addition, the nylon powder essential to the present invention is
Any material commonly used in cosmetics may be used, such as powders of nylon 6, nylon 12, and the like. The average particle size is preferably 5 to 30 particles, and may be selected appropriately taking into account the color of the product and other ingredients. These may be selected as necessary and used alone or in combination. . It is sufficient to use the blending amount in the range of 1 to 10% by weight,
More preferably, it is 5 to 10% by weight.

By changing the blending amount of nylon powder within the above range, the degree of suppression of the gloss of the coating film can be controlled. If it is less than 1% by weight, the matting effect will not be sufficient, and if it exceeds 10% by weight, the viscosity will increase, affecting the strength of the coating film and usability, and the makeup retention will tend to decrease. The shape of the nylon powder is not particularly limited, and the particle size is 7. S may be within the above range.

Furthermore, in addition to the above-mentioned essential ingredients, the nail beauty preparation of the present invention contains resins, plasticizers, and solvents that are commonly used in nail beauty preparations.

Resins are those commonly used in nail beauty products, and include synthetic resins such as alkyd resins and acrylic resins, as well as natural resins such as shellac and rosin, and are blended in a range of 5 to 20% by weight. The plasticizer is a well-known one such as camphor, phthalate ester, citric liquor ester, etc., and the blending amount is 2 to 8.
Weight%. In addition, the solvents are ester-based, alcohol-based,
It is an aromatic type, and the blending amount is generally 80 to 85% by weight.

In addition to the above-mentioned components, pigments, pearlescent agents, fragrances, ultraviolet absorbers, humectants, and other minor components may be appropriately selected and blended in the nail beauty preparation according to the present invention within a range that does not interfere with the present invention.

[Example] Next, the present invention will be further explained by giving examples. These do not limit the invention in any way.

First, 10 types of nail beauty preparations, whose formulations are shown in Table 1, Examples [1] to [3] and Comparative Examples [1] to [71] were prepared, and in order to confirm the effects of the present invention, the following experiments were carried out. In Table 0, the amounts are in parts by weight.
