Why is it easy to tear nail polish off?
Tearing nail polish is the raw material of resin, and it is an organic and environmentally friendly water-soluble nail polish. Definitely not as strong as ordinary nail polish. Because it is natural and organic nail polish, when our nails begin to metabolize themselves, the protective layer on the nail surface and the substances formed during nail growth will make the torn nail polish tilt or fall off.
Harm of tearing nail polish
Tearable nail polish is also toxic. Tearable nail polish is generally water-based nail polish, which is relative to oily nail polish. Oily nail polish is actually the kind of durable nail polish that we usually use. Its matrix is various organic solvents, all of which have certain toxicity. The matrix of water-based nail polish is water and acrylic acid, which makes water-based nail polish odorless, and acrylic acid is also toxic. As mentioned above, the tearable nail polish is also toxic, and the acrylic acid in its matrix is also an organic solvent, but it uses the emulsion of acrylic acid and water, which will greatly reduce the concentration of organic solvent in nail polish, and it will be relatively diluted, which is not only easier to apply, but also less harmful. Therefore, girls who are worried about unsafe nail polish can choose to use tearable nail polish, which is water-based nail polish.
