Starting September 1, 2025, the European Union has banned popular gel nail polishes containing a chemical called trimethyl benzoyl diphenyl phosphine oxide (TPO). This ingredient is used in many gel nail polishes to make them dry quickly under UV or LED light and to give them a shiny, long-lasting finish.
The ban affects all gel nail polishes with TPO immediately. Nail salons across Europe must stop selling and using these polishes. They are also required to dispose of any stock containing TPO safely. Manufacturers will need to reformulate their products without this chemical to comply with the new regulation.
The reason for the ban is health concerns. European regulators have classified TPO as “carcinogenic, mutagenic or toxic to reproduction.” This means the chemical could cause cancer, genetic mutations or harm to reproductive health. These conclusions are mainly based on animal studies, which showed possible links between TPO and fertility issues.
Experts say the ban is a precautionary measure by the EU. Dermatologist Dr. Hannah Kopelman said the decision is more about caution than confirmed harm to humans, as most research has been limited to animals. However, European safety rules often ban products that show even potential risks.
Consumers in the EU are advised to ask nail salons about the products they use. After the ban, salons should only offer gel polishes that are free of TPO. The ban also means that salons and distributors in the EU cannot supply or sell TPO containing products anymore.
The United States has not banned TPO. Gel nail polishes with this ingredient remain available there, and the FDA and CDC advise customers to read product labels carefully and follow safety directions. The U.K. plans to follow a similar ban in 2026.
Gel nail polish is popular because it lasts longer and resists chipping better than regular nail polish. However, this product avoids making different versions. Some alternative gel nail polishes without TPO are already available.
This ban shows Europe’s cautious approach to cosmetic safety, prioritizing health risks over beauty benefits. Nail polish users in Europe will have to switch to safer options for their manicures starting now.
In summary, the EU ban on TPO in gel nail polish marks a significant change in the beauty industry, aiming to protect consumer health by removing potentially harmful chemicals from cosmetic use.
