Recently, a well-known nail polish brand found that the formaldehyde exceeded the standard by 82 times. What is “formaldehyde”? Presumably many people immediately think of the pungent smell emanating from brand-new decorations, furniture, cars, etc., as well as occasional news reports that clothing, cosmetics, black-hearted foods, etc. contain excessive formaldehyde. In the end, where is formaldehyde sacred, and why is it ubiquitous like the Monkey King? Should we be worried about formaldehyde exceeding the standard?
