What kind of nail polish is harmless to human body?

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 component of liquid, which mainly uses acetone, ethyl acetate (commonly known as banana oil), phthalate, formaldehyde, benzene and so on. There are many kinds of pigments, including natural pigments and artificial pigments. Of course, artificial pigments are the most widely used now, but many of them are toxic, and some of them also contain heavy metal elements, so they may be harmful to human body. Sudan red, as we all know, is a carcinogen. Natural pigments may also be mixed with harmful components, but they can be purified and removed, but the removal technology is quite difficult and costly, and is generally not adopted by manufacturers. I don't know that the solvent components of ordinary nail polish are basically toxic and harmful substances. Among them, phthalates, benzene and formaldehyde are the most powerful, followed by acetone and ethyl acetate. Among the harmful components of nail polish, phthalates will hinder the normal hormone 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. 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. When volatilized, they will produce dazzling pungent odor and pollute indoor air (their volume will expand 1000 times after volatilization). In the case of long-term inhalation, they may cause damage to the nervous system and have strong irritation to 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 weak, resulting in "nail damage rather than nail repair". Therefore, some instructions for the use of nail polish say: "It is best to apply nail polish in a ventilated room, otherwise it may cause dizziness. Generally, nail polish contains a lot of toxic chemicals, which is harmful to nails when used frequently. Now the healthier nail polish is water-based nail polish. Experts also pointed out that this water-based nail polish is much healthier than oily nail polish, which is not corrosive to nails and does no harm to human body ~ ~ ~
