On June 25, 2025, the European Chemicals Agency (ECHA) added three compounds—two linear siloxanes and one reactive azo dye—to the Candidate List of Substances of Very High Concern (SVHCs) under the REACH Regulation. This brings the list to a historic high of 250 entries.
The new additions are characterized by high persistence and bioaccumulation (vPvB) or reproductive toxicity, and primarily affect the cosmetics, automotive care, and textile sectors.
This move creates immediate reporting, notification, and safety data sheet updating obligations for companies that manufacture, import, or use these compounds.

1. Regulatory context
The Candidate List constitutes the preliminary step to the eventual inclusion of a substance in Annex XIV (Authorization List). Its extension reflects the strategy of the European Union to strengthen the protection of human health and the environment through the progressive substitution of hazardous substances. For the industrial sector, each update involves assessing the internal chemical inventory and verifying the supply chain to prevent non-compliance.
2. Added substances and toxicological profile
Substance (common name) | CAS / EC | Reason for inclusion | Common uses* |
1,1,1,3,5,5,5-Heptamethyl-3-[(trimethylsilyl)oxy]trisiloxane | 17928-28-8 / 241-867-7 | vPvB, art. 57(e) | Fragrances, cosmetics, coatings |
Decamethyltetrasiloxane | 141-62-8 / 205-491-7 | vPvB, art. 57(e) | Personal care products, lubricants, waxes |
Reactive Brown 51 (Na/K salt) | — / 466-490-7 | Toxic to reproduction, art. 57(c) | Textile dyes and finishes |
*Summary information based on official ECHA communication and sectoral summaries.
3. Regulatory implications for the industry
Duty to provide information (Article 33 REACH) : Suppliers must inform customers and consumers about the presence of any of these SVHCs in articles when the concentration exceeds 0.1% w/w.
Notification to ECHA (Article 7.2) : Manufacturers and importers of articles with SVHC above the threshold must notify the agency within a maximum of six months – 25 December 2025 for this update.
Safety Data Sheet (SDS) Update : All affected SDS must reflect the new classification and risk management measures.
SCIP and ecolabeling : Items containing these substances must be declared under the SCIP (Waste Framework Directive) and are, in principle, excluded from the EU Ecolabel.
