Is nail polish toxic? Why do nail polishes have a pungent smell?

Nail polish is a product that many girls use when doing manicures, but many of us will find that the smell of nail polish is very strong, so we need to know whether the strong smell of nail polish is toxic? Why do nail polishes have a particularly pungent smell?

Yes, nail polish has some toxins, but the toxin content is not very high. Compared with previous nail products, nail polish has the least harm to the human body. Although nail polish can minimize the harm, it still has certain harm. Frequent application of nail polish will only make the nails dull. The nail polish used before, although it can beautify the nails, has a certain corrosive effect on the nails and has a pungent smell, which is extremely harmful to human health. Compared with nail polish, nail polish has no irritating smell and is compatible with the common advantages of glue and nail polish. It dries in a very short time and keeps the gloss longer. The raw material of nail polish is very safe. It is a natural resin material with a small amount of chemical substances added. After processing, it will quickly solidify on the nails to prevent the smell from being inhaled by the human body.

The pungent smell of nail polish. In fact, the culprit of this smell is formaldehyde, which we often talk about and avoid. Long-term contact can cause inflammation of the eyes, nose, and throat, coughing, asthma attacks, shortness of breath, nausea, vomiting, rash, nosebleeds, headaches, and dizziness. Since 1987, the International Agency for Research on Cancer (IARC) has listed formaldehyde as a Class 2A carcinogen. The U.S. Environmental Protection Agency (EPA) also stated that long-term and high-frequency use of formaldehyde-containing substances may pose a potential risk of cancer. In ordinary nail polish, in order to achieve the purpose of making the nail polish dry quickly, a large amount of acetone and ethyl acetate are added. The characteristics of these two ingredients are that they are extremely volatile, so the nail polish can dry quickly. However, acetone and ethyl acetate are hazardous chemicals, flammable and explosive. When volatilizing, they produce a dizzying irritating odor, pollute the indoor air (their volume will expand a thousand times after volatilization), and may cause harm to the nervous system in the case of long-term inhalation, and are also highly irritating to the mucous membranes.

No. The main ingredients of nail polish are 70%-80% volatile solvents, about 15% nitrocellulose, a small amount of oily solvents, camphor, titanium dioxide and oil-soluble pigments. The main ingredients of nail polish glue are natural resins and some color materials. This material will solidify under ultraviolet light instead of volatilizing, and it will form a plastic-like film. The solvent contained in nail polish evaporates to form a colored film, which can show color after being attached to the nail. There is no need for lighting, so nail polish is usually placed in a transparent bottle and sealed when stored. The gloss, wear resistance and firmness of nail polish glue are better than nail polish. The most important thing is that it has almost no volatile gas, is basically odorless, and only takes one or two minutes to dry. And more different nail styles can be made. But nail polish glue needs to be placed in a light-proof bottle and kept away from light.

Nail polish is not a flammable item. Its main component is natural resin, which is non-toxic, odorless, healthy and environmentally friendly, and cannot be ignited. Nail polish has the potential risk of being flammable and explosive, because too many chemicals are added to its ingredients, and long-term use will be harmful to the human body. Because the main component of nail polish is natural resin, it is light-hardening. After applying nail polish on the nails, you need to use a baking lamp to irradiate it so that the nail polish can be completely dried. If there is no baking lamp, you can use ordinary light instead, but the effect will be weaker and it will take longer.
