Common Harmful Chemicals in Nail Top & Base Coat
Chemical Name
Why it’s harmful
Xylene is a colorless, flammable liquid with a sweet odor that can be found in cosmetic products. Its functions include enhancing fragrance and perfuming the skin, as well as serving as a solvent to dissolve other substances in the formulation. However, it's important to note that exposure to xylene can lead to various health issues, including irritation of the eyes, nose, skin, and throat, along with symptoms like headaches, dizziness, confusion, and loss of muscle coordination.
Benzophenone (BZP) is a photoinitiator, fragrance enhancer, and ultraviolet stabilizer, used in a variety of industrial applications. Despite not being registered as a pesticide in the U.S., it's involved in the production of insecticides and agricultural chemicals. Its toxic effects on humans are scarcely documented, but it presents little hormonal activity on cell lines. Animal studies show it possesses no estrogenic activity, but it can transform into derivatives with such activity under UV irradiation. It did not show reproductive toxicity or carcinogenicity in rats and mice, respectively, even at high doses. It can be bioactivated through specific enzymes. For aquatic life, fathead minnow larvae were more sensitive to BZP, ranking it in the middle of the toxicity order of six benzene derivatives.

Formaldehyde is a colorless, flammable gas with a pungent smell that's naturally produced in small quantities in human bodies and is also known as methanal amongst other names. It's used in the production of various items such as fertilizers, paper, plywood, and urea-formaldehyde resins as well as in some foods and household products like antiseptics, medicines, and cosmetics. Exposure to formaldehyde, which can occur through breathing contaminated indoor air, tobacco smoke, or ambient urban air can lead to respiratory symptoms, irritation of the eyes, nose and throat and has been linked to lung and nasopharyngeal cancer as well as leukemia. The EPA considers formaldehyde a probable human carcinogen (Group B1) and inhaling it can cause bronchospasm and pulmonary edema. Commercially, it's sold as formalin in solutions of 37%, 44%, or 50% and long-term exposure can cause first-degree burns, skin sensitization, squamous cell nasal cancer, and chronic pulmonary obstruction.

Methylisothiazolinone can reportedly cause allergic contact dermatitis in workers who interact with products containing it. This substance is recognized as a contact allergen for consumers using cosmetics that include it. It can cause skin burns and sensitization, and inhaling it may lead to corrosive injuries in the upper respiratory tract and lungs. Ingesting this substance is harmful, and inhalation is toxic. This preservative is linked to the category of isothiazolinones.
