Four new substances added to the Candidate List

The Candidate List of substances of very high concern (SVHCs) for authorisation now contains 201 substances.


ECHA has added four new substances to the Candidate List due to their toxicity to reproduction, endocrine disruption and a combination of other properties of concern. The latter causes probable serious effects to human health and the environment, giving rise to an equivalent level of concern to carcinogenic, mutagenic and reprotoxic (CMR), persistent, bioaccumulative and toxic (PBT) and very persistent and very bioaccumulative (vPvB) substances, respectively.

The decision to include two of the substances, number 2 and 3 in the table below, was taken with the involvement of the Member State Committee (MSC).

One further substance, the last in the table below, has been added to the list having been identified as an SVHC by the European Commission due to its endocrine-disrupting properties. The MSC referred this SVHC proposal to the Commission in 2016.

Substances included in the Candidate List for authorisation on 16 July 2019 and their SVHC properties:


# Substance name EC number CAS number Reason for inclusion Examples of use(s)
1 2-methoxyethyl acetate 203-772-9 110-49-6 Toxic for reproduction (Art. 57 (c)) Not registered under REACH.
2 Tris(4-nonylphenyl, branched and linear) phosphite (TNPP) with ≥ 0.1% w/w of 4-nonylphenol, branched and linear (4-NP) Endocrine disrupting properties (Art. 57(f) – environment) Primarily used as an antioxidant to stabilise polymers.
3 2,3,3,3-tetrafluoro-2-(heptafluoropropoxy)propionic acid, its salts and its acyl halides (covering any of their individual isomers and combinations thereof) Equivalent level of concern having probable serious effects to the environment (Art. 57(f) – environment)

Equivalent level of concern having probable serious effects to human health (Article 57(f) – human health)

Processing aid in the production of fluorinated polymers.
4 4-tert-butylphenol 202-679-0 98-54-4 Endocrine disrupting properties (Art. 57(f) – environment) Used in coating products, polymers, adhesives, sealants and for the synthesis of other substances.


The Candidate List is a list of substances that may have serious effects on human health or the environment. Substances on the Candidate List are also known as substances of very high concern and are candidates for eventual inclusion in the Authorisation List. Once they are on the Authorisation List, industry will need to apply for permission to continue using the substance after the sunset date.

Companies may have legal obligations resulting from the inclusion of the substance in the Candidate List. These obligations may apply to the listed substance on its own, in mixtures or in articles. In particular, any supplier of articles containing a Candidate List substance above a concentration of 0.1 % (weight by weight) has communication obligations towards customers down the supply chain and to consumers. In addition, importers and producers of articles containing the substance have six months from the date of its inclusion in the Candidate List (16 July 2019) to notify ECHA. Information on these obligations and related tools are available on ECHA’s website.
