EU Bans Two Gel-Manicure Chemicals in Cosmetics Effective Sept. 1

The rule follows EU CMR classifications based on animal toxicology to reduce repeated occupational exposure for nail technicians.

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.
