What now?

The regulation was adopted on 12 May 2025 and will apply from 1 September 2025, with no distinction between placing on the market and making available.

Non-compliant products must be withdrawn from the EU market before 1 September 2025.

Special attention must be given to the substance diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (CAS 75980-60-8, INCI name Trimethylbenzoyl Diphenylphosphine Oxide), which was previously allowed in Annex III for use in artificial nail systems. From September 2025, this substance must be removed from the formulation of artificial nail products, and the products remaining on the market containing the substance must be removed, as now it is listed in Annex II.
