Common Harmful Chemicals in Nail Dip Powder
Chemical Name
Why it’s harmful
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.

The study on 1,576 U.S. workers exposed to TiO2 for over a year from 1956 to 1985 showed no increase in lung cancer or chronic respiratory disease, and no cases of pulmonary fibrosis. Cases of pulmonary fibrosis related to TiO2 exposure have been reported, possibly due to silica contamination. There are no listed effects for short-term or long-term exposure. Although NIOSH recognises ultrafine TiO2 as a potential occupational carcinogen, data is insufficient to classify fine TiO2 similarly. Epidemiological studies do not provide clear evidence of lung cancer risks from TiO2 dust exposure.
Benzoyl peroxide is a versatile compound used in various industries, including pharmaceutical and cosmetic industries, mainly to treat mild acne and acne rosacea. In humans, occasional symptoms of overexposure include skin, eye, and mucous membrane irritation, and dermatitis. It has also shown potential for inducing DNA damage in cultured human cells. In animal studies, benzoyl peroxide has caused irritation, erythema, and increased keratinocytes in guinea pigs and mice. Studies on mice and rats showed no significant increase in tumors, and it was not found to be mutagenic in a Salmonella strain. In embryonic studies, however, it caused malformations at moderate frequency. Furthermore, it mediates its effect by inducing various genetic and biochemical changes in different cell types.
Methyl methacrylate (MMA) is a bonding agent in certain artificial nail products, offering quicker setting and stronger adhesion. However, MMA exposure is associated with adverse health effects like dermal toxicity and respiratory tract issues. Acrylates and methacrylates are monomers commonly used in various industries, including cosmetics, medicine, dentistry, and manufacturing, for producing plastics.
