On 25 June 2025, the European Chemicals Agency (ECHA) has added three new chemicals to the candidate list of substances of very high concern (SVHC). The Candidate List of SVHC now contains 250 entries for chemicals.
Entries added to the Candidate List on 25 June 2025 and their properties:
| No. | Substance Name | EC No. | CAS No. | Reason for inclusion | Use |
| 1 | 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. |
| 2 | Decamethyltetrasiloxane | 205-491-7 | 141-62-8 | Very persistent and very bioaccumulative, vPvB (Article 57e) | Used in cosmetics, personal care products, and perfumes; also used in non-metal surface treatment products, lubricants, greases, and automotive care products. |
| 3 | 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. |
Under REACH, companies have legal obligations when their substance is included – either on its own, in mixtures or in articles – in the Candidate List.
If an article contains a Candidate List substance above a concentration of 0.1 % (weight by weight), suppliers have to give their customers and consumers information on how to use it safely. Consumers have the right to ask suppliers if the products they buy contain substances of very high concern. Importers and producers of articles have to notify ECHA if their article contains a Candidate List substance within six months from the date it has been included in the list (25 June 2025).
Under the Waste Framework Directive, companies also have to notify ECHA if the articles they produce contain substances of very high concern in a concentration above 0.1 % (weight by weight). This notification is published in ECHA’s database of substances of concern in products (SCIP).
