What’s new?

Hexamethylindanopyran (CAS No 1222-05-5) is an ingredient used in cosmetic products as a fragrance and perfuming agent and is currently restricted in Annex III/336 to the EU Cosmetics Regulation (EC) No. 1223/2009.

On January 2025, the European Chemicals Agency (ECHA) received a proposal from France for a new harmonised classification and labelling for Hexamethylindanopyran, including a classification as Reprotoxic 1B.

On the 25^thof March 2026, the Risk Assessment Committee (RAC) of the European Chemicals Agency (ECHA) concluded that Hexamethylindanopyran shall be classified for Reprotoxicity, as Repr. 1B.

What now?

Following this opinion, a ban on Hexamethylindanopyran in cosmetics in the EU might be enforced, unless a successful exemption application under Article 15 of the EU Cosmetic Products Regulation is submitted.
