New EU regulations for cosmetics and gel nail polish. What is CPNP, and how are consumers and professionals affected?
The new year has brought significant developments for the cosmetics sector in the European Union. From 1 September 2025, new provisions come into effect for gel nail polish and product notification through the CPNP (Cosmetic Products Notification Portal).
What is CPNP, and why is it necessary?
The CPNP is the official European platform through which manufacturers, importers and distributors are required to notify cosmetic products before placing them on the market. This process ensures transparency, traceability and the safety of cosmetics for the end consumer.
These changes are particularly significant for the nail products industry, as two widely used ingredients are being banned entirely:
Dimethyltolylamine – previously unrestricted, it is used as a polymerisation accelerator in gel nail polish.
Trimethylbenzoyl Diphenylphosphine Oxide (TPO) – permitted under specific conditions (up to 5%) exclusively in professional products. It acts as a photoinitiator in UV-curable systems and has been widely used in professional nail products to date.
The scientific assessment reached the following conclusions:
- Dimethyltolylamine may be carcinogenic.
- TPO is toxic to reproduction.
Based on these findings, both substances are included in Annex II to Regulation (EC) No 1223/2009, which lists substances prohibited in cosmetic products in the EU.
From 1 September 2025 onwards:
– No company may make products containing these substances available on the market.
– All stock containing TPO or Dimethyltolylamine must be withdrawn or replaced.
