JPS61289019A - Nail beautifying enamel remover - Google Patents

Abstract

PURPOSE:The titled remover, obtained by incorporating a water swellable gel material, e.g. sodium montmorillonite, with a specific organic solvent and readily handleable without causing danger of causing a fire and no smell of the organic solvent in the form of a gel or paste. CONSTITUTION:A nail beautifying enamel remover containing (A) a water swellable gel material, e.g. sodium montmorillonite, and (B) a hydrophilic organic solvent, readily soluble in nitrocellulose and having >=100 deg.C boiling point, e.g. lactone such as gamma-butyrolactone, acid amide such as tetramethylurea, ester such as methyl lactate or ethylene glycol monoacetate, or alcohol ether such as methyl cellosolve, in mixture. The amount of the component (A) to be incorporated in preferably 2-12%, particularly 5-7%. A fat or oil, e.g. squalane, is incorporated to protect the nail and a vitamin is incorporated to keep the health around the nail.

Description

DETAILED DESCRIPTION OF THE INVENTION All conventional nail enamel removers are solutions, and mainly contain organic solvents such as low-light ketones such as acetone, ethyl acetate, butyl acetate, and esters. Flammable organic solvents such as nJ are used. These substances pose a risk of fire when used, have a particularly strong odor, and are so permeable and soluble that they can damage the nails and the skin around the nails. Furthermore, since it is in a liquid state, the organic solvent will leak out when the container is knocked over or the cap is opened during use. The present invention is a water-swollen sodium montmorillonite gel body, in which at least one
Hydrophilic right-handed solvents with a boiling point of 00°C or higher, namely lactones γ-butyrolactone and γ-valerirolactone, acid amides tetramethylurea, 1.3demethyl2imigzoline, N-methylpyrrolidone, NN・-Dimethylformamide, esters methyl lactate, ethyl lactate, ethylene glycol monoacetate propylene carbonate, alcohol ethers methyl cellosolve, cellosolve, diethylene glycol monoether, diacet alcohol dimethyl sulfoxide, etc. are mixed together to make a paste. To remove beautiful nail enamel, make a beautiful nail enamel remover, apply the paste on the nail, give it some time to dissolve the beautiful nail enamel, and wipe it with gauze or tissue paper as needed to remove the beautiful nail enamel. is effective.

Therefore, the paste-like beautiful nail enamel remover according to the present invention has no odor from organic solvents, contains oils such as squalane to protect the nails from excessive damage, and contains nutrients such as vitamins to improve the health of the nails and the area around the nails. can be maintained.

Furthermore, since it is a paste rather than a solution, there is no risk of spillage or
There is no loss due to volatilization and transpiration, and the risk of contamination or fire due to leakage or escape is also avoided. Therefore, it is completely unaffected by vibrations in a running car or train and can be used with peace of mind.

As a beautiful nail enamel remover, this invention is unique in terms of its effect on nail health, its economic efficiency in removing enamel, and the novelty of its form.
