REACH SVHC List Expands to 247 Substances Following January 2025 Update

The European Chemicals Agency (ECHA) has finalized the 32nd update of the REACH Candidate List, officially adding five new substances of very high concern (SVHCs) in January 2025. Additionally, one existing entry has been updated, marking another step in the EU’s commitment to regulating hazardous chemicals.

This update was confirmed during the December 2024 Member State Committee (MSC) meeting, correcting earlier reports that suggested six new additions. With this update, the total number of SVHCs on the Candidate List has increased to 247.

Newly Added Substances (SVHCs) – January 2025

1. Octamethyltrisiloxane (CAS 107-51-7, EC 203-497-4) – Identified as very persistent and very bioaccumulative (vPvB), commonly used in cosmetics, lubricants, coatings, and textiles.
2. O,O,O-triphenyl phosphorothioate (TPPT) (CAS 597-82-0, EC 209-909-9) – A persistent, bioaccumulative, and toxic (PBT) substance found in lubricants, hydraulic fluids, and cooling liquids.
3. Reaction mass of triphenylthiophosphate and tertiary butylated phenyl derivatives (CAS 192268-65-8, EC 421-820-9) – Classified as PBT, commonly used in lubricants, greases, and hydraulic liquids.
4. Perfluamine (CAS 338-83-0, EC 206-420-2) – A perfluorinated compound flagged for vPvB concerns, used in electronics and cooling systems.
5. 6-[(C10-C13)-alkyl-(branched, unsaturated)-2,5-dioxopyrrolidin-1-yl] hexanoic acid (CAS 2156592-54-8, EC 701-118-1) – Toxic for reproduction, primarily used in metalworking fluids, lubricants, and greases.

Updated Entry:

• Tris(4-nonylphenyl, branched and linear) phosphite (TNPP) – Now classified for endocrine-disrupting properties in the environment.

Key Discussions from the December MSC Meeting

Beyond the Candidate List update, the MSC also:

• Reviewed prioritization strategies for moving substances from the Candidate List to the Authorisation List.
• Discussed compliance check decisions and substance evaluations, including a notable decision on 2,6-di-tert-butyl-p-cresol.

Under REACH guidelines, companies must fulfill legal obligations, ensuring consumers receive information on safe usage. Importers and producers must promptly notify ECHA of any articles containing Candidate List substances. Compliance with the Waste Framework Directive's (EU WFD) SCIP database notification requirements further underscores the significance of regulatory adherence.
