In its December meeting, ECHA’s Member State Committee (MSC) agreed to identify n-hexane as a substance of very high concern, SVHC, a first neurotoxic case of equivalent level of concern (ELOC). Another substance, 4,4'-[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]diphenol and its salts, was identified without the committee’s involvement.  

ECHA will add both substances to the Candidate List of substances of very high concern in February 2026.

The MSC also discussed ECHA’s recommendation of priority substances to be added to the REACH Authorisation List and the draft update of the Community Rolling Action Plan for substance evaluation.  

In addition, the committee agreed on the first testing proposal for nanomaterials to request further clarifying studies on its chemical properties.
