REACH SVHC: ECHA to Add Six New Substances to Candidate List in January 2025

The European Chemicals Agency (ECHA) has announced the addition of six new substances of very high concern (SVHCs) to the Candidate List, set to take effect in January 2025. This decision follows the December meeting of ECHA's Member State Committee (MSC), where significant progress was made in identifying and evaluating potentially harmful chemicals. The six substances to be added to the Candidate List are:

• Octamethyltrisiloxane (EC 203-497-4, CAS 107-51-7)
• O,O,O-triphenyl phosphorothioate (EC 209-909-9, CAS 597-82-0)
• Reaction mass of: triphenylthiophosphate and tertiary butylated phenyl derivatives (EC 421-820-9, CAS 192268-65-8)
• Perfluamine (EC 206-420-2, CAS 338-83-0)
• Tris(4-nonylphenyl, branched and linear) phosphite
• 6-[(C10-C13)-alkyl-(branched, unsaturated)-2,5-dioxopyrrolidin-1-yl] hexanoic acid (EC 701-118-1, CAS 2156592-54-8)

The MSC also reviewed the prioritisation approach for substances to be included in the Authorisation List. This review is crucial in determining which substances may face stricter regulations in the future.
