Description

3-layer nail lacquer remover composition

The present invention relates to a three-layer nail lacquer remover composition, and more particularly to a whitening phenomenon caused by degreasing and dehydration of nails and to damage of the resulting nails, and to a stable three-layer nail lacquer remover composition having a beautiful appearance of various colors. will be.

Conventional monolayer nail lacquer removal liquid consists of alkylacetate and acetone, which are low boiling point organic solvents capable of dissolving the main components of nail lacquer, such as nitrocellulose, which is the main film-forming agent of nail lacquer, and resins that provide adhesion. However, they cause strong degreasing and dehydration for the nails, which in turn causes damage to the nails and their surrounding skin.

In addition, moisturizers such as propylene glycol, glycerin or 1,3-butylene glycol were added to the nail lacquer removal liquid composition to protect the nails and the surrounding skin, but they reduced the nail lacquer removal effect, which is the fundamental function of the nail lacquer removal liquid. Precipitation or separation of the components resulted in damage to the appearance.

Various multilayer nail lacquer removal solutions have been proposed to solve the problem of the single layer nail lacquer remover and to make the appearance of the product beautiful.

Hereinafter, a conventional method and a known technique for removing a single layer nail lacquer will be described.

In Japanese Laid-Open Patent Publication No. 57-122013, a two-layer nail lacquer removal liquid having an oil layer has been proposed, but vigorous stirring conditions are required to disperse the oil phase. There was a drawback of mixing them by shaking, and Japanese Laid-Open Patent Publication No. H1-143818 describes a two-layer nail lacquer removal liquid using acetone, liquid oil, and a body of titanium oxide, mica, iron oxide, kaolin, etc. This large mica and titanium oxide were precipitated, making it difficult to maintain a beautiful appearance.

In addition, the Japanese Patent Application Laid-Open Nos. 57-122013 and 1-1-143818 are separated into two-layered forms, and are not only limited in terms of color expression, but also have a monotonous limitation in appearance.

In the case of the multi-layer nail lacquer removal liquid described in Korean Patent Application No. 87-4544, silicone oil such as methyl polysiloxane is added to prevent nail degreasing and dehydration. Due to the effects of the active bar silicone oil, there was a disadvantage that the nail lacquer stains on the nail.

In addition, Japanese Patent Laid-Open No. Hei 1-160908 proposes a three-phase nail lacquer removal liquid containing acetone, purified water, propylene carbonate, and a hydrocarbon solvent when the boiling point is 30 ° C. or higher. However, the present invention claims that the three-phase nail lacquer composition of the upper layer mainly composed of liquid oil and the middle layer composed of propylene tansan, a hydrocarbon aqueous solution, acetone, and the lower layer composed of water and acetone, but the propylene carbonate has a specific gravity of 1.2 or more. As it is heavier than the water phase component constituting the lower layer, it is impossible to exist as an intermediate phase, and the hydrocarbon solvent also has solubility in acetone and propylene carbonate, which are claimed as constituents of the intermediate layer, and the solubility and specific gravity because the upper component is worse than that of the liquid oil. In view of the layered phase separation phase in which phase separation is performed by a difference, the present invention can not only be composed of two layers of an upper layer and a lower layer, and thus it is difficult to maintain a stable three-layer separation form.

In addition, Japanese Patent Application Laid-Open No. 52-145529, which is a nail enamel remover composition prepared in the form of a pack containing acetone, alkyl acetate, lanolin, polyethylene glycol, purified water, and modified alcohol and absorbing nail enamel removal solution on cotton wool, has a hygienic aspect. Although there was an emphasis on economy and economics, it is impossible to show inconvenience in use and beautiful appearance.

Korean Patent Application No. 90-11240 proposed a three-layer separate nail lacquer removal liquid containing acetone, purified water, hydrocarbon liquid oil, and alkyl acetate, which have excellent overall characteristics such as nail lacquer removal effect, moisturizing property, and excellent appearance taste. On the other hand, only the high boiling point (more than 300 ℃) hydrocarbon-based liquid oil is included as the upper component, showing some oily feeling on nails after nail lacquer removal, and the upper layer is suspended slightly at temperature drop (10 ℃). There was a disadvantage that could hinder the beauty.

Therefore, the present invention is to solve the above problems, acetone, lower alkyl acetate, purified water, high boiling point (300 ℃) hydrocarbon-based liquid oil and low viscosity (20 centipoise or less, 25 ℃) hydrocarbon in liquid It is an object of the present invention to provide a stable three-layer nail lacquer remover composition having excellent moisturizing effect and softening effect and having excellent appearance by using oil in an optimal weight ratio.

Hereinafter, the present invention will be described in detail.

The present invention is a nail lacquer removal liquid composition containing acetone, lower alkyl acetate, high boiling point and low viscosity liquid oil, purified water, 20-60% by weight of acetone, 5-30% by weight of lower alkyl acetate, 10-30% by weight of purified water The present invention relates to a three-layer separable nail lacquer remover composition comprising 5-35% by weight of a high boiling point and low viscosity hydrocarbon-based liquid oil.

The three-layer nail lacquer remover composition according to the present invention contains 20-60% by weight of acetone as a main ingredient, and when the amount of acetone is less than 20% by weight, the main effect of removing the nail lacquer is worse. If it exceeds 60% by weight, solubility in the pre-assigned alkyl acetate and purified water becomes high, and thus it is difficult to achieve a stable three-layer structure.

In the present invention, the lower alkyl acetate is used 5-30% by weight, it is preferable that the molecular weight is 150 or less, such as ethyl acetate, butyl carbonate, amyl acid.

If the amount of lower alkyl acetate used is less than 5% by weight, it is difficult to obtain a stable intermediate layer, and the effect of removing nail lacquer is inferior. If it exceeds 30% by weight, the effect of removing nail lacquer is excellent but a balanced three-layer structure cannot be obtained. do.

In addition, the high-boiling point and low-viscosity hydrocarbon-based liquid oils of the upper layer component of the present invention can be used in 5-35% by weight, and less than 5% by weight does not exhibit satisfactory mildness and is insufficient to form an upper layer structure, while 35% by weight. Mild feeling is excellent when used in more than%, but the effect of removing nail lacquer is not preferable.

As high boiling point liquid oil, non-polar hydrocarbon oils such as squalane and liquid paraffin, which have a boiling point of 300 ° C. or higher, can be used.However, when high boiling point liquid oil is used alone as an upper component, oily feeling appears after removing nail lacquer, In the following), the upper layer is somewhat suspended, which may damage the appearance.

In order to solve the problem of using a high boiling point liquid oil alone, when using a low viscosity (20 centipoise or less, 25 ° C) hydrocarbon-based liquid oil with less oil feeling and a usability, it forms a stable upper layer and nail lacquer remover. The low viscosity hydrocarbon-based liquid oils having a molecular weight of dodecane, hexadecane, eicos acid, and the like have a molecular weight of 300 or less and preferably 20 centipoise or less at 25 ° C.

The combination ratio of the high boiling point liquid oil and the low viscosity liquid oil is in the range of 20:80 to 80:20, which is less oily, and is suitable for forming a stable three-layer type, and satisfactory usability by appropriately adjusting the combination ratio thereof. And a mild feeling. Particularly preferably, the combination ratio of the high boiling point liquid oil and the low viscosity liquid oil is in the range of 50:50, which is most suitable for showing layered stability and excellent usability.

In addition, cleansing water should contain 10-30% by weight for nail lacquer removal and balanced layering.

In addition, by adding a moisturizing agent, such as glycerin and propylene glycol, a flavoring agent, and a pigment as needed, the odor and appearance can be improved further.

The three-layer nail lacquer remover composition of the present invention is acetone, lower alkyl acetate, high boiling point and low viscosity hydrocarbon-based liquid oil, purified water, by appropriately combining and using within a predetermined weight percent range, phase separation in the specific gravity and solubility difference It shows good layer separation speed and balanced three-layer phase, and shows excellent nail lacquer removal effect, moisturizing effect and mild usability.

Hereinafter, the present invention will be described in more detail based on Examples and Comparative Examples.
