Description

Aqueous nail polish composition and manufacturing method therefor {WATER SOLUBLE MANICURE COMPOSITION AND THE PREPARATION METHOD THEREOF}

The present invention relates to an aqueous nail polish composition and a method for manufacturing the same, and more particularly, coating stability on the surface of the nail or toenail is good, and in particular, it is excellent in gloss property, water resistance and durability, but it is not necessary to remove it by using a separate solvent. The present invention relates to an aqueous nail polish composition which can be removed by hand.

The oily nail polishes currently used are those obtained by adding components such as plasticizers, organic and inorganic pigments to film forming components such as nitrocellulose, and resins such as alkyd resins, sulfone resins, amide resins, and acrylic resins. It is common to dissolve in solvents, and these solvent-based oil-based nail polishes do not contain water, and when used and thickened, there is a risk of damage to nails or skin, yellowing or loss of gloss. I can't say. In use, there is a problem in which the user inhales the volatilized organic solvents (VOCs), and the organic solvents may reduce the separation of nails and the physiological function of the skin. Use of such a manicure resin composition in an enclosed room may cause symptoms such as a headache and a high risk of fire. In addition, careless handling of infants is also a problem. Since changing oil-based manicures based on organic solvents into water-based manicures and making environmentally friendly nail cosmetics is exploding in demand by modern people who prefer environmental protection and health, various research and development is conducted to develop new products. Resin manufacturing methods are being reported one after another, and commercial products are also available.

However, existing aqueous manicures do not have good coating stability on the surface of nails or toenails, and in particular, it is difficult to make use of gloss, water resistance and durability are often poor, and peeling is not performed well even when removed. Many problems still exist, such as removal with the use of solvents.
