1, the composition of some ink is slightly different from nail polish, but the difference is not big.

2, most of them can be mixed, so nail polish can also be used for printing.

Extended data:

First, nail polish:

Nail polish is a cosmetic widely used for fingernails or toenails. It is rich and colorful, with both aesthetic and protective functions.

The components of ordinary nail polish are generally composed of two kinds, one is solid components, mainly pigments, flash substances and so on; One is the solvent composition of liquid, which mainly includes acetone, ethyl acetate, phthalate, formaldehyde and so on.

Second, the composition:

The components of ordinary nail polish are generally composed of two kinds, one is solid components, mainly pigments, flash substances and so on; One is the solvent composition of liquid, which mainly includes acetone, ethyl acetate, phthalate, formaldehyde and so on.

1, pigment

There are many kinds of pigments, including natural pigments and artificial pigments. Of course, artificial pigments are still used the most now, but many artificial pigments are toxic, so they may be harmful to human body. Sudan red, as we all know, is a carcinogen.

Step 2: Solvent

I don't know that the solvent components of ordinary nail polish are basically toxic and harmful substances. Among them, phthalates and formaldehyde are the most powerful, followed by acetone and ethyl acetate.

Among the harmful components of nail polish, phthalates will hinder the normal hormonal balance, leading to serious reproductive damage and other health problems; Benzene and formaldehyde are carcinogens. It has also been reported that some ingredients in nail polish may have an impact on the health of the fetus, so we should pay close attention to them.

3. Other ingredients

In order to make nail polish dry quickly, a lot of acetone and ethyl acetate are added to ordinary nail polish. These two ingredients are characterized by easy volatilization, so nail polish dries quickly.

However, acetone and ethyl acetate are dangerous chemicals. They are flammable and explosive, and when volatilized, they produce a dizzy and irritating smell, polluting indoor air (their volume will expand 1000 times after volatilization). In the case of long-term inhalation, they may be harmful to the nervous system and have a strong stimulating effect on mucous membranes.

If you have a baby at home, it is even more dangerous to contact such ingredients. Another disadvantage of these organic solvents is that after repeated use on nails, nails will become discolored, brittle and white, and even nails will fall off from the skin of the nail bed below, resulting in "nail damage rather than nail repair". So some instructions for nail polish say, "It's best to apply nail polish in a ventilated room, otherwise it may cause dizziness ..." This is a fact.
