Technical Field
The invention belongs to the field of cosmetics, and particularly relates to chitin whisker modified water-based nail polish remover and a preparation method thereof.
Background
The nail polish is a cosmetic for decorating and improving the aesthetic degree of nails, and can form a layer of friction-resistant film on the surface of the nails to play a role in protecting and beautifying the nails. Currently, nail polishes used by people can be classified into solvent-based nail polishes and water-based nail polishes. Solvent-based nail polishes contain volatile, irritating organic solvents, and also tend to yellow and embrittle the nail, which is a poor user experience. The components of the water-based nail polish mainly comprise additives such as water, a water-based film forming agent, pigments and the like. Therefore, the water-based nail polish has no pungent smell and no corrosiveness, and is more healthy and environment-friendly. However, the existing water-based nail polish still has some defects, such as poor gloss, poor water resistance, poor adhesion, poor wear resistance, no antibacterial property and the like, and cannot meet the requirements of consumers.
