Overview
- Regulation (EU) 2025/877 entered into force on 1 September 2025, adding TPO and DMTA/DMPT to the Cosmetics Regulation’s list of prohibited substances.
- The prohibition applies to manufacture, marketing and use of cosmetics containing these ingredients across EU member states, covering both retail products and salon applications.
- TPO is a UV/LED photoinitiator and DMTA/DMPT are accelerators in semipermanent gels, pushing brands and salons to withdraw affected items or shift to reformulated systems.
- Coverage describes immediate operational disruption and inventory changes, with some reports noting no extensions or grace periods for existing stocks.
- Accounts differ on whether pre-purchased products may still be used, and businesses are seeking official guidance as risk assessments highlight greater exposure for workers than occasional clients.
