Description

Gel type nail enamel remover composition

The present invention relates to a nail enamel remover composition that gives a fresh and neat texture when removing nail enamel, and more particularly, to a composition of a gel type nail enamel remover that is excellent in protecting nails and can prevent excessive degreasing and dehydration. .

A nail enamel remover aims at removing the nail make-up of a nail enamel film | membrane, and generally the mixture of the solvent which melt | dissolved nitrocellulose or resin is used. Common solvents are mainly acetone, ethyl acetate, butyl acetate, and the like, and a small amount of oily substance is added thereto for the purpose of protecting nails. This type of nail enamel remover uses a large amount of acetone and acetate esters, which is odorous and irritating, and removes nail enamel and also removes moisture and oil present in the nail, which leads to dehydration and degreasing of nails. Since the formulation is transparent, it is difficult to increase the aesthetic value as a cosmetic, and the viscosity is low, so that it easily penetrates into puffs or tissues, making it difficult to control the amount of use and volatilization. In addition, the conventional nail enamel remover is extremely inconvenient due to the use of glass and plastic containers, and clothing and the like may be contaminated due to breakage of the container and leakage of contents.

Due to this inconvenience, various attempts have been made for the development of a gel type nail remover.

For example, Japanese Patent Publication No. 4-164012-A discloses a gel type nail enamel remover composition in which a thickener is added to propylene carbonate, and Korean Patent Application No. 1996-14457 discloses hydroxycellulose and carbomer. Or nail enamel remover comprising N-methyl-2-pyrrolidone as a main component or an auxiliary component, which can be prepared and used in a liquid, jelly, or gel phase using polyacrylic acid, and also disclosed in Korean Patent Application 1991-022117 describes gel nail enamel removers using silica and vinylpyrrolidone / vinylacetate copolymers as gelling agents.

In addition, Korean Patent Application No. 1994-36645 discloses a gel nail enamel remover containing acrylate / alkyl acrylate crosspolymer, synthetic hectorite and hydroxypropyl cellulose as gelling agent, and Canadian Patent No. 1,154,347 describes carboxy. Polyoxymethylene polyacrylic acid is used as a gelling agent.

However, the gel enamel remover on the gel has a drawback in that it is sticky and contains a large amount of volatile substances, so that the nail enamel removing effect is inferior or the contents easily flow down on the nail. These conventional removers also have not been considered in terms of temperature stability and long term storage stability, and do not exhibit various viscosity characteristics.

The present inventors have diligently researched to provide a nail enamel remover composition of various properties from low viscosity to high viscosity, eliminating the disadvantage of inferior nail enamel removal effect due to a large amount of sticky and inert substances in use, which is a disadvantage of conventional gelling agents. The present invention has been accomplished by discovering that the nail enamel remover according to the present invention described below can exhibit desired properties.

Accordingly, an object of the present invention is to provide a nail enamel remover having various advantages such as high enamel removal effect, good usability, and very stable properties to the external environment.

In one aspect, the present invention is a gel that can be packaged in a tube or a pump container, which is easy to carry, prevents damage to the nail due to degreasing and dehydration of the nail, and reduces the odor of an unpleasant solvent such as in a liquid nail enamel remover. Nail enamel remover.

Since the nail enamel remover on the gel of the present invention can be packaged in a tube or pump type container, the nail enamel remover is extremely portable compared to a conventional liquid nail remover using a glass container and can eliminate the possibility of contamination such as clothing due to the container breakage. Can be.

Hereinafter, the nail enamel remover on the gel of the present invention will be described in more detail.

In the remover of the present invention, the gelling agent is polyacrylamide, vinylpyrrolidone / vinylacetate copolymer (molar ratio 6: 4) and gelatin. Acetone, ethyl acetate and butyl acetate are used as a solvent, and a remover is prepared by combining purified water with propylene glycol as a moisturizing agent, C _13-14 isoparaffin as a skin conditioning agent, and a protective ingredient for nails and skin.

The remover composition of the present invention has a soft gel feeling and has a mild feeling even after removing the nail enamel and has a merit of minimizing skin damage since only a desired nail part can be erased because it is a gel phase in use.

The gelling agent components used in the gel-like nail enamel remover of the present invention, the polyacrylamide is composed of a polymer of acrylamide monomer, vinylpyrrolidone / vinylacetate copolymer having a molar ratio of 6: 4, and gelatin, and the gelling agent is ethanol. Because of its excellent compatibility with polar solvents such as acetone, propylene glycol, and glycerol, the texture of the gel is unprecedented.

When the gelling agent is used alone, the polyacrylamide compounding amount may be in the range of 0.1 to 25% based on the total weight of the composition, and may represent the texture of the gel. The vinylpyrrolidone / vinylacetate copolymer Is 0.1% to 30%, and gelatin is suitable to use 0.1 to 25%. However, when the gelling agent is used alone, it is insufficient to obtain the texture and stability of the gel when used, and the gel feels poor when used, so that the gelling agent has excellent gel texture and stability and refreshing feeling through the ideal combination of three gelling agents. The nail remover on the gel could be completed.

In the remover composition according to the present invention, the preferred blending amount of the gelling agent is 0.5 to 8.0% of polyacrylamide and 0.2% to vinylpyrrolidone / vinylacetate copolymer (molar ratio 6: 4) based on the total weight of the composition. 10% gelatin and 0.1 to 6.0% of the mixture is good to use.

The most preferred blending ratios showing good texture, stability and usability of the gel were obtained by using 0.1 to 2.0% of polyacrylamide, 0.5 to 1.5% of vinylpyrrolidone / vinylacetate copolymer, and 0.2 to 0.8% of gelatin.

Acetone, ethyl acetate, and butyl acetate are used as the solvent used in the gel nail enamel remover of the present invention, and the amount of such solvents is preferably used in an amount of 20 to 90%. -65% is the most suitable.

8 to 40% of the water used in the present invention can be used, and when the blending amount is less than 8%, it is difficult to expect a sufficient gel effect even when the concentration of the mild water and the gelling agent is high, and when the concentration exceeds 40%. The nail enamel remover, a basic feature of the nail enamel remover, is slightly less effective. In addition, it is preferable to contain C ₁₃ -C ₁₄ isoparaffin as a skin conditioning agent.

In addition to the above essential ingredients used in the gel nail remover of the present invention, a suitable amount of ingredients commonly used as cosmetic additives such as moisturizers (for example, propylene glycol), dyes, pigments, pearlescents, and ultraviolet absorbers may be used. Suitable compositions suitable for the purpose of the invention can be prepared. The amount of such additives is not particularly limited, and for example, the skin conditioner may be included in an amount of 0.1 to 2.0% based on the total weight of the composition, but this is merely exemplary, and the range of use of the specific additives is determined by those skilled in the art. As it is obvious at the technical level, the content of any additive is within the scope of the present invention.

As described above, the nail enamel remover of the present invention can be easily packaged in a tube or the like, which can be easily carried, exhibits excellent texture of the gel, and has a mild feeling when removing the nail enamel, and is a gel phase when used. It can only erase the skin, which has the advantage of minimizing skin damage.
