Two, the harm of nail polish smell
In ordinary nail polish, in order to achieve the purpose of quick drying of nail polish, a large amount of acetone and ethyl acetate components are added. The two components are characterized by volatilization, so nail polish can be quickly removed. However, acetone and ethyl acetate are dangerous chemicals. They are flammable and explosive. They produce dizzy pungent smell during volatilization and pollute the indoor air (their volume will expand a thousand times after volatilization). In the case of long-term inhalation, they may be harmful to the nervous system and have strong irritation to the mucous membrane. If there is a baby at home, it is more dangerous to be exposed to such ingredients.
