Recently, the Shanghai Drug Administration released the “2022 1st cosmetic supervision andsampling quality announcement”. Among them, a peelable acrylic dip glitter powder by Meitronics was detected with trichloromethane content as high as 589.449 micrograms/gram, which is more than 1400 times the limit value of the national standard. After this test, the nameof the product to apply for re-inspection was still determined to be substandard products. This news, many netizens said, trichloromethane is carcinogenic, and exceeds the limit by so much, that the future acrylic dip glitter powder can no longer be coated; coated will cause cancer.
So, acrylic dip glitter powder, in the end, is not carcinogenic? Can you still apply it in the future? First of all, let’s look at the panic triggered by trichloromethane.
Trichloromethane is a colorless and transparent liquid with a special odor and easy to volatilizeand is a suspected carcinogen. If a large number of inhaled trichloromethane, it can cause acutepoisoning and damage to human organs. The initial symptoms of poisoning are headache, dizziness, nausea, vomiting, wet and hot skin, and after a period of time, mental disturbance,
superficial breathing, and coma will appear. In addition, trichloromethane is light-sensitive, andwhen exposed to light, it easily interacts with oxygen in the air, gradually decomposing andgenerating carbonyl chloride and hydrogen chloride, both of which are highly toxic.

In short, excessive amounts of trichloromethane are harmful to humans and require strict control of its concentration in contact with humans. On October 27, 2017, trichloromethane was listedinthe list of carcinogens by the World Health Organization’s International Agency for Research onCancer in category 2B. on July 23, 2019, trichloromethane was included in the list of toxic andhazardous water pollutants (batch 1). The relevant health standards state that the maximumexposure concentration of trichloromethane in an enclosed space is 20 mg/m3, and exceedingthis concentration has the potential to cause poisoning. However, this can be avoided if galglitter acrylic dip glitter powder is used.
However, it is the dose that determines the toxicity of the substance, and low concentrations of trichloromethane can be made into disinfectants. Therefore, the concentration of trichloromethane in acrylic dip glitter powder can be used safely as long as it does not exceed thespecified value, i.e., it meets the national standard.
In order to achieve a fast drying effect, some acrylic dip glitter powder contains a large number of organic solvents, such as acetone, ethyl acetate, trichloromethane, etc. These organic solvents are characterized by extremely volatile and produce dizzying and irritating odors, which arehighly irritating to the mucous membranes and nervous system. Therefore, acrylic dip glitter powder, which has a heavy smell and makes people feel dizzy, should be avoided as muchas possible.
Finally, it should be reminded that even acrylic dip glitter powder with simple ingredients and less toxicity should not be applied every day. This is because continuous application of acrylic dipglitter powder will prevent the nails from breathing properly and destroy the keratinocytes of thenails, making them thinner and thinner and prone to breakage. In addition, whether it is water-based acrylic dip glitter powder or oil-based acrylic dip glitter powder, you should use nail polish remover to remove it after application to prevent damage to your nails. Even after cleaningup with compliant galglitter acrylic dip glitter powder, it should be reapplied after a periodof time, usually at least 2 to 3 weeks.
