The European Union (EU) has banned a chemical called Trimethylbenzoyl Diphenylphosphine Oxide (TPO), a common ingredient in many gel nail polishes. The ban started on September 1, 2025, and from that date, TPO can no longer be sold, imported, or used in cosmetics across EU countries.
TPO has been linked to serious health concerns. Studies show that it is carcinogenic (can cause cancer), mutagenic (can cause genetic changes), and toxic to reproduction. It has also been associated with skin allergies and sensitisation, causing reactions for some users.
In May 2025, the European Commission formally added TPO to the list of banned substances through a regulation called Omnibus VII. This move also included other harmful chemicals in cosmetics. As a result, nail salons across Europe must throw away all products containing TPO and switch to safer, TPO-free alternatives.
The ban will affect thousands of nail technicians, salons, and beauty product retailers across the continent. Authorities have warned that businesses who do not comply could face heavy fines, with penalties reaching as high as €22,000 per violation.
Experts say this ban is mostly a precautionary step. Dr. Hannah Kopelman, a dermatologist, explained that while there isn’t yet strong evidence from large human studies proving harm, the possible risks are serious enough to require action.
She told Wellness Pulse, “The European Union is banning it out of caution. From a medical perspective, I see this as a precautionary move rather than a response to strong human evidence.”
This ban in Europe may influence other parts of the world to reconsider the safety of chemicals used in beauty products. For Nigeria, where gel nail polish is also popular, it raises awareness about the potential dangers of some cosmetic ingredients.
Consumers are advised to always check product labels and choose safer options. Meanwhile, local regulators might study these developments to ensure public safety in the Nigerian beauty industry.
