Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an emulsion gel nail enamel remover (hereinafter referred to as enamel remover).
Regarding More specifically, it has a beautiful milky appearance,
The present invention relates to an emulsion gel-like enamel remover which has a good effect of removing enamel and a treatment effect of nails and is also excellent in stability over time.

[0002]

2. Description of the Related Art Most of the currently used nail enamel (hereinafter referred to as enamel) is mainly composed of nitrocellulose. As enamel remover to remove this, conventional acetone, ketones such as methyl ethyl ketone,
Acetic acid esters such as ethyl acetate and butyl acetate, ethyl cellosolve, propylene carbonate and other removal bases,
Many of these contain water, an oily component and the like, and carboxyvinyl polymer (Canadian Patent No. 1154347, Japanese Patent Laid-Open No. 61-257912, etc.) and hydroxypropyl cellulose (Japanese Patent Laid-Open No. 1-242515).
It is said that a gel-like material containing a gelling agent such as the above has good usability. Recently, a compression-disintegrating resin capsule containing an oil agent (Japanese Patent Application Laid-Open No. 2-289507), a liquid crystal composition (Japanese Patent Application Laid-Open No. 4-164012), and the like are further added thereto to impart a treatment effect to the nails. Also, there are known ones that produce a beautiful appearance with a liquid crystal.

Further, JP-A-2-289507 describes that ethylenediaminetetrapolyoxyethylenepolyoxypropylene is suitable as an alkaline agent when a gel enamel remover is prepared using a carboxyvinyl polymer. ing.

[0004]

The above-mentioned gel-like enamel remover mainly composed of a removing base such as ketones, acetic acid esters, ethyl cellosolve, propylene carbonate, water and a gelling agent has a good enamel removing effect. However, due to the strong degreasing power, even the oil originally held by the nail itself may be removed, and the nail may be damaged.

Therefore, in order to impart a treatment effect to the nails, it has been considered that an oil content is mixed by emulsification to obtain an emulsion gel-like enamel remover, but the system contains a high-concentration low boiling point polar solvent. Therefore, it was difficult to emulsify with a normal emulsification method. Further, even if emulsified, it is difficult to obtain an emulsion having good stability over time and a good feel, and the effect of removing enamel may be reduced in some cases.

Further, when the oil content is encapsulated in the compression-disintegrating resin capsule or the liquid crystal composition is blended as described above, it is difficult to obtain a beautiful emulsion-like appearance.

Further, when oil is blended in the system, excess oil remains on the surface of the nail after removing the enamel, so that if the enamel is reapplied immediately after removal, the nail tends to repel the enamel.

[0008]
