Description

Nail Enamel Topcoat Composition

The present invention relates to a fast-drying parfum nail enamel top cord composition which applies a nail enamel and then reapplies it to impart gloss and a pleasant scent, and more specifically, methyl acetate; Carbitol or methylcellosulf alone or mixtures thereof; And diacetone alcohol or ethyl alcohol alone or mixtures thereof.

Nail enamel top coat is a kind of transparent nail enamel which aims to form beautiful appearance by maintaining the color appearing after applying ordinary nail enamel to nails and enhancing gloss. Nail enamel top coat is usually It is composed of the same composition as the transparent nail enamels, and nitrocellulose is used as the main film former to enhance only gloss, and auxiliary film formers include toluene sulfonamide / formaldehyde resin and the like.

In addition, it contains a plasticizer and a solvent, and esters such as butyl acetate and ethyl acetate are used as main solvents, and alcohols are used as a co-solvent. Therefore, the smell of the conventional nail enamel topcoat does not escape the irritating odor of the conventional lacquer base of the ester system, and the drying speed is also typically applied because the topcoat composition is applied three times after applying the nail enamel twice. It is the same as triple application of nail enamel, so the drying speed is very slow.

The present inventors have completed the present invention as a result of diligent research to improve the fragrance of the conventional nail enamel topcoat and to provide a quick drying nail enamel topcoat composition under such a situation.

That is, an object of the present invention is a nail enamel topcoat composition containing a film former, a plasticizer, an auxiliary film former, and a solvent, wherein the solvent is one selected from methyl acetate, carbitol, metelcellosulf, and diacetone alcohol. Or it provides a quick-drying nail enamel topcoat composition characterized in that it contains a mixture of two or more kinds.

Another object of the present invention is a film former, nitrocellulose 10 to 40% by weight auxiliary film former is one or a mixture of two or more selected from toluene sulfonamide / formaldehyde resin or sucrose acetate / isobutyrate resin 5 to 20% by weight; 3 to 10% by weight of dibutylphthalate or die camper alone or mixtures thereof as a plasticizer; 3 to 30% by weight of butyl acetate or ethyl acetate alone or a mixture thereof and 0.3 to 40% by weight of one or more mixtures selected from methyl acetate, carbitol, methylcellosulf and diacetone as solvents. It is to provide a quick-drying nail enamel topcoat composition characterized in.

The nail enamel topcoat composition according to the present invention is nitrocellulose, resin, etc. as a main film forming agent, dibutyl phthalate, die camphor as a plasticizer, butyl acetate, ethyl acetate, methyl acetate, etc. , Carbitol, niacetone alcohol ethyl alcohol and the like, and in addition, it further contains pigments and flavors.

Referring to each component of the composition of the present invention in detail as follows.

The quick-drying nail enamel topcoat composition according to the present invention comprises 10 to 40% by weight of nitrocellulose. When the amount of nitrocellulose is less than 10% by weight, there is a concern that the formation of the film is poor, and when the amount is more than 40% by weight, the pressure on the nail is large and the film tends to be broken due to the formation of an excessive film.

Toluene sulfonamide / formaldehyde resin and sucrose acetate / isobutyrate, which are auxiliary film formers in the composition of the present invention, are used alone or as a mixture in an amount of 5 to 20% by weight, and are glossy to the coating of nitro cellulose, which is the main film forming agent. And action to enhance adhesion.

The main plasticizer used in the composition of the present invention is dibutyl phthalate or die camphor or mixtures thereof, and the amount used is 3 to 10% by weight.

These plasticizers impart flexibility to the ends of the cellulose tissue of the nitrocellulose film to make the film flexible. If the plasticizer is used in an amount outside the above range, 3 to 10% by weight is appropriate because the drying rate, hardness of the formed film, or plasticizing effect are lowered.

Solvents used in the composition according to the present invention include one or a mixture thereof selected from butyl acetate or ethyl acetate and are used in an amount of 3 to 30% by weight. If the amount of these solvents is 3% by weight or less, the existing strong nail enamel base odor cannot be masked, and when used in the range of 3 to 30% by weight, the persistence of the fragrance may be increased to achieve the desired object of the present invention. Can be.

In addition, methyl cellosolve and carbitol selected from methyl acetate, methyl cellosulf, carbitol, diacetone alcohol and one or two or more kinds thereof in an amount of 0.3 to 40% by weight are odorless solvents. It plays a role in reducing base odor, especially methyl acetate, which gives the composition a pleasant odor and its high volatility gives it a refreshing feel when used on nails.

In addition, by using methyl cellosulf and carbitol in an appropriate amount, it plays an important role to enhance the fragrance and persistence of the fragrance by enhancing the sticking and dissipation of the fragrance, and also plays an auxiliary role to simultaneously promote the plasticity and gloss of the top coat composition. do.

Alcohols usable as the solvent of the composition of the present invention include diacetone alcohol or ethyl alcohol, and these act as a co-solvent to enhance the solvent ability of the esters, the main solvent, and quick drying with methyl acetate and refreshing feeling after use. Play a role.

By using methyl acetate, alcohols, and odorless solvents as described above, it is possible to manufacture a product of odor that can sufficiently mask the base odor by facilitating the release of the odor.

In addition, color can be added to the appearance by adding a dye.

Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to these Examples.
