Overview
- The EU prohibition on the photoinitiator TPO in cosmetic products, including gel polishes, took effect on September 1, 2025 under Omnibus VII.
- Regulators classified TPO as carcinogenic, mutagenic or toxic to reproduction following animal studies, leading to precautionary restrictions.
- Salons and retailers in the EU have been told to remove or replace existing TPO stock, with some reports citing fines up to €22,000 for non‑compliance.
- Great Britain has not implemented a ban, and the UK cosmetics trade body CTPA expects any restriction in 2027, though other reports suggest late 2026.
- Manufacturers are rolling out TPO‑free lines and alternative photoinitiators, as experts advise correct curing for home kits and note HEMA reactions are more common.
