EU Bans Toxic Gel Nail Polish Ingredient Linked To Fertility Issues

Health officials across Europe have banned a chemical widely used in gel nail polish over fears it could harm human fertility, but the ingredient will still be allowed in the UK and US for now.
The European Union’s new rules, effective 1st September, prohibit the use of trimethylbenzoyl diphenylphosphine oxide (TPO) in all cosmetic products. TPO is a key component in gel polishes that speeds up drying under UV light and keeps nails glossy and long-lasting.
Nail salons in the EU, as well as countries that follow EU cosmetic regulations like Norway, must stop using TPO-based gels and safely dispose of existing stock. Manufacturers will need to reformulate products without it. Experts say the UK may follow suit by the end of 2026.
Some in the beauty industry have criticized the ban. Doug Schoon, a scientific consultant, warned it could create unnecessary costs and waste safe products. Belgian retailer ASAP Nails and Beauty Supply echoed the concern, calling the ban a potential “major economic damage” for small businesses.

The ban comes amid growing evidence that toxic chemicals in cosmetics, like TPO and phthalates, can disrupt hormones, contributing to fertility problems and conditions such as endometriosis, which has risen dramatically worldwide over the last 30 years. Experts warn that these chemicals can also increase the risk of breast cancer, developmental delays in babies, and other long-term health issues.
Professor Katie Burns, a specialist in toxic chemicals and fertility, said:
“These are chemicals that stay in the body for a long time, hidden in fatty tissue. They impact the immune system, and in some women we believe this may trigger reproductive problems and endometriosis.”
While gel manicures are popular for their glossy, long-lasting finish, experts are urging caution and highlighting safer alternatives as TPO is phased out across Europe.
