There should be 90% girls who have painted nail polish. Now there are more and more kinds of nail polish on the market, which have the functions of tearing and discoloring, but my mother says it causes cancer. Is it true?/You don't say.
Last year, Shanghai Drug Administration issued the "Announcement on the Quality of the First Phase of Cosmetic Supervision and Sampling in 2020". Among them, the chloroform content of a well-known peeling nail polish is as high as 589449μg/g/g, which is more than 1.400 times of the national standard limit.
After this test, the famous products applied for re-inspection are still judged as unqualified products. As soon as this news came out, many netizens said that chloroform was a carcinogen, which exceeded the standard seriously. In the future, nail polish could not be applied, which would cause cancer. So, is nail polish carcinogenic? Can I draw in the future?
In fact, the dose is the key to determine the toxicity of substances.
Chloroform is a colorless and transparent liquid with a special smell, which is easy to volatilize as a suspected carcinogen. If a large amount of chloroform is inhaled, it will cause acute poisoning and damage human organs.
chloroform
The initial symptoms of poisoning are headache, dizziness, nausea, vomiting and moist skin. After a period of time, there will be symptoms such as mental confusion, poor breathing and coma. In addition, chloroform is sensitive to light, which easily reacts with oxygen in the air and gradually decomposes into acetochlor and hydrogen chloride, both of which are highly toxic.
In a word, excessive chloroform is harmful to human body, so it is necessary to strictly control its contact concentration with people. 201710127 October, chloroform was included in the list of Class 2B carcinogens published by the International Agency for Research on Cancer of the World Health Organization. 20 19 1 On October 23rd, chloroform was listed in the List of Toxic and Harmful Water Pollutants (batch number1. According to relevant hygienic standards, the maximum contact concentration of chloroform in a closed space is 20 mg/m3, which may cause poisoning.
Can nail polish be painted or not?
The composition of nail polish is very complicated. In addition to chloroform, it often contains heavy metals, plasticizers, ammonia dyes and other substances, which have a certain impact on human health.
But the dose is the key to determine the toxicity of the substance, and low concentration chloroform can also be made into disinfectant. Therefore, the concentration of chloroform and other substances in nail polish can be used safely as long as it does not exceed the specified value and meets the national standards.
Nail polish can't be applied every day. In order to achieve quick-drying effect, some nail polishes contain a lot of organic solvents, such as acetone, ethyl acetate and chloroform. This kind of organic solvent is characterized by volatility, which will produce a dizzy pungent smell and have a strong stimulating effect on mucosa and nervous system. Therefore, we should try to avoid using nail polish with strong smell and dizziness.
Appendix: Pay attention to buying nail polish.
Pay attention to big brands as much as possible, and don't buy some three-no products on the cheap. In order to gain more benefits, some small manufacturers do not strictly control the index of nail polish formula, and the safety of added raw materials is poor, which brings potential risks to consumers.
Finally, I need to remind everyone that even nail polish that meets national standards cannot be applied every day. Because continuous application of nail polish will hinder the normal breathing of nails, destroy the keratinocytes of nails, and make nails thinner and easier to break. In addition, whether it is water-based nail polish or oily nail polish, it should be removed with nail polish remover after application to prevent nail damage. After the nail polish is washed, it will take some time to use it.
