From Monday 1st September, the use of TPO (Trimethylbenzoyl Diphenylphosphine Oxide) has been banned in Monaco and across the European Union, with immediate effect. The substance, commonly found in semi-permanent nail varnishes, has been classified as toxic for reproduction.

The Department of Social Affairs and Health has confirmed that the new measures apply particularly to professionals in the nail industry, who must ensure full compliance. Existing stocks of products containing TPO must be eliminated without delay.

Regulation aligned with EU law

The prohibition follows the entry into force of the European Regulation (EU) No. 2025/877, Omnibus VII, which restricts the use of substances deemed carcinogenic, mutagenic, or toxic for reproduction in cosmetic products.

Impact on the beauty sector

While the ban will require nail technicians and salons to adapt their practices, it also provides an opportunity for the industry to transition towards safer alternatives. The government has urged professionals to take all necessary measures to comply, ensuring the wellbeing of both clients and employees.
