Popularize knowledge: Nail polish is basically made of nitrocellulose and chemical solvents such as acetone, ethyl acetate, ethyl lactate and phthalic acid tincture. This kind of nail polish is loved by people because it can make nails red and moist and does not fade for a long time. However, most of these raw materials have certain biological toxicity and should be avoided from entering the human body, causing chronic poisoning. After applying nail polish, don't hold food by hand, so as to avoid nail polish sticking to food and prevent "poison from entering the mouth". It is particularly important to note that you should not eat oily foods such as fried dough sticks and oil cakes by hand, because the compounds contained in nail polish are fat-soluble compounds, which are easily dissolved in oil, so be extra careful. Nail polish contains a substance called phthalate. If this substance is absorbed by the human body for a long time, it will not only do great harm to human health, but also cause miscarriage and give birth to deformed children. Therefore, pregnant women or lactating women should avoid using cosmetics marked "phthalates" to prevent phthalates from causing miscarriage or baby malformation.
