On June 25, 2025, European Chemicals Agency (ECHA) introduced three hazardous chemicals to the Candidate List of substances of very high concern (SVHC). The list now contains 250 entries, some of which are groups of chemicals so the overall number of impacted chemicals is higher.
The entries added to the Candidate List are shown below:
| Substance name | EC No. | CAS No. | Reason for inclusion | Example of use |
| 1,1,1,3,5,5,5-heptamethyl-3-[(trimethylsilyl)oxy]trisiloxane | 241-867-7 | 17928-28-8 | Very persistent and very bioaccumulative, vPvB (Article 57e) | Used as a laboratory reagent, in cosmetics and personal care products and perfumes and fragrances |
| Decamethyltetrasiloxane | 205-491-7 | 141-62-8 | Very persistent and very bioaccumulative, vPvB (Article 57e) | Used in cosmetics and personal care products, in lubricants and greases and in automotive care products |
| Tetra(sodium/potassium) 7-[(E)-{2-acetamido-4-[(E)-(4-{[4-chloro-6-({2-[(4-fluoro-6-{[4-(vinylsulfonyl)phenyl]amino}-1,3,5-triazine-2-yl)amino]propyl}amino)-1,3,5-triazine-2-yl]amino}-5-sulfonato-1-naphthyl)diazenyl]-5-methoxyphenyl}diazenyl]-1,3,6-naphthalenetrisulfonate; Reactive Brown 51 | 466-490-7 | - | Toxic for reproduction (Article 57c) | Used in textile treatment products and dyes |
Consequences of inclusion on the Candidate List
Once a substance is identified as an SVHC, it is placed on the Candidate List for Authorization. According to EU REACH Regulations, suppliers of an article containing SVHC in a concentration of more than 0.1% must provide following information to downstream:
Provide SDS to downstream if the concentration of SVHC on its own or in preparations exceeds 0.1%
Provide safety use instruction to downstream recipient if the concentration of SVHC in products exceeds 0.1%. This equivalent information should be supplied to consumers within 45 days when requested
EU manufacturers, importers or only representative (OR) of SVHC shall notify ECHA if:
The substance is present in those articles in quantities totalling over one tonne per producer or importer per year;
The substance is present in those articles above a concentration of 0.1 % weight by weight (w/w).
In addition, starting from January 5, 2021, companies that have products containing more than 0.1% of SVHC are required to submit notifications through ECHA’s substances of concern in products (SCIP) database.
