Nail polish is also called "nail polish". Its main components are 70%-80% volatile solvent, 15% nitrocellulose, a small amount of oily solvent, camphor, titanium dioxide and oil-soluble pigment.
Harm of nail polish
1. Nails are damaged, turning yellow and dark.
Nail polish has a variety of beautiful colors because of the addition of a large number of pigment components, including various mineral pigments and synthetic pigments. These pigments slowly attach to nails, causing them to become darker and dimmer. The darker the color of nail polish, the more obvious the phenomenon of pigment precipitation.
2. Dry, inflamed and prickly fingers
Incomplete disinfection of nail tools will indirectly cause fungal infection between nails. On the other hand, the chemical solvent components in nail polish will irritate the skin around nails, make the skin around the edges of fingers horny and hard, which will easily lead to inflammation, dryness or barbs in the process of manicure, and even lead to paronychia in serious cases.
The smell of nail polish is poisonous, which makes people dizzy.
Some nail polishes contain a large amount of acetone and ethyl acetate, which is characterized by its volatility, producing a dizzy pungent smell (its volume will expand by 65,438+0,000 times after volatilization), and it is very irritating to mucous membrane and nervous system.
4. Make nails brittle, broken layer by layer, and grow slowly.
Continuous application of nail polish will hinder the "normal breathing" of nails and destroy the keratinocytes of nails. Because of the lack of oxygen caused by poor breathing and the chronic corrosion of nail polish, nails naturally become thinner and thinner, easily broken and grow slowly.
5. The stronger the phototherapy nail, the more painful it is.
Phototherapy nail, also known as gel nail, is to mix a certain proportion of photoinitiator A solution in resin nail powder, and under the irradiation of ultraviolet lamp, the gel will produce curing reaction on the nail. Therefore, the adhesion of phototherapy nail polish to nails is greater than that of ordinary nail polish, which requires professional nail polish remover and then polishing, which is more harmful to nails and finger edges than ordinary nail polish.
6. The nail is corroded, resulting in the separation of the nail from the nail bed.
It is easy to corrode nail polish. Many people use nail polish, which causes the nail to separate from the skin of the nail bed below, causing the nail to peel off and become arc-less. Long-term use causes nails to become thin and brittle, become unhealthy, and are more prone to diseases such as onychomycosis.
7. The thicker the coating, the higher the risk.
Nail polish is toxic. The more layers of nail polish you apply, the higher the risk of cancer. When painting nail polish, it is necessary to strengthen ventilation and reduce inhalation of excessive toxic substances. It is best to choose products close to the production date.
Nail polish is toxic, which will affect people's health and even cause cancer. Toxic chemicals in nail polish products include dibutyl phthalate (DBP), toluene and formaldehyde, among which DBP and toluene are recognized as toxins affecting development. The FDA and the cosmetic ingredient review team believe that these two substances should be controlled within a safe range. Formaldehyde is a known carcinogen.
8. Cancer risk
There is a chemical called phthalate in nail polish, which has a high content and mainly plays a softening role. This substance will enter the human body through the respiratory system and skin. If used in excess, it will increase the risk of breast cancer in women.
Another survey shows that nearly 90% of nail polish has no Chinese logo on the packaging and label. The most prominent problem of these unqualified nail polishes is the use of prohibited pigments, which contain a large number of fluorescent agents that may cause cancer. In addition, many skin polishes and nail enhancers used in nail art are unknown and may contain toxic substances.
Because nails are easy to absorb foreign substances, long-term use of nail polish with excessive heavy metals such as lead, arsenic, mercury and benzene may lead to chronic poisoning and even cancer.
9. It will lead to miscarriage
Nail polish generally contains a substance called "phthalate", which is likely to cause fetal abortion and affect the growth of babies. Phthalate ester is a colorless and odorless oily liquid with good volatility, which can make nail polish more uniform and lasting. It can enter the human body through the skin, respiratory tract and digestive tract and accumulate in adipose tissue, which is not easy to be excreted. If it is often used in large quantities for a long time, the residual concentration of this substance in the human body is high, which will cause harm to the liver, kidney, cardiovascular system and reproductive system and affect the endocrine function of the human body. Long-term use by pregnant women may affect the development of baby's reproductive organs, especially boys, who are prone to impotence or infertility in adulthood.
