EU REACH – ECHA Adds Three Hazardous Chemicals to the Candidate List

Vol. 1483 | 13 Jul 2025

ECHA added three hazardous chemicals to the EU SVHC Candidate List, including two vPvB substances and a reproductive toxicant dye. The List of SVHC now contains 250 entries for chemicals that can harm people or the environment.

On 25 June 2025, ECHA added three new substances. Two newly added substances are very persistent and very bioaccumulative (vPvB). They are used, for example, in cosmetics, personal care products and in automotive care products.

Reactive Brown 51 is toxic for reproduction and is used in textile treatment products and dyes.

The Candidate List of substances of very high concern (SVHC) now contains 250 entries for chemicals that can harm people or the environment.

Substance name	EC number	CAS number	Reason for inclusion	Examples of uses
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

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 must 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 must notify ECHA if their article contains a Candidate List substance within six months from the date it has been included in the list (21 January 2025).

EU and EEA suppliers of substances on the Candidate List, supplied either on their own or in mixtures, must update the safety data sheet they provide to their customers.

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).
