Publication of initial assessments of substances added to the EU REACH Candidate list in 2021


HSE, with the Environment Agency, has assessed 11 substances and substance groups that were submitted for identification as Substances of Very High Concern (SVHCs) in EU REACH.

The assessments consider if formal identification as SVHCs is an appropriate action for these substances under UK REACH.


The assessments have been published on the HSE website, along with supporting information on SVHCs in UK REACH:

UK REACH substances of very high concern (SVHC)

As a result of these assessments, HSE and the Environment Agency have identified 4 priority substances or substance groups requiring regulatory management options analysis (RMOA).

Preparation of RMOAs: call for evidence

HSE is opening a call for evidence on 4 substances and substance groups that have recently been identified as SVHCs by the EU.

HSE, with the Environment Agency, is preparing RMOAs for the substances and substance groups below.

To inform these RMOAs, HSE is opening calls for evidence and invites interested parties to respond with general information and information on specific topics.

DOTL  Dioctyltin dilaurate, stannane, dioctyl-, bis(coco acyloxy) derivs., and any other stannane, dioctyl-, bis(fatty acyloxy) derivs. wherein C12 is the predominant carbon number of the fatty acyloxy moiety Closes 10 April

1,4-dioxane Closes 10 April

SBAA Small brominated alkylated alcohols Closes 10 April

PDDP Phenol, alkylation products (mainly in para position) with C12-rich branched or linear alkyl chains from oligomerisation, covering any individual isomers and/or combinations thereof Closes 10 April

The RMOAs will assess the best regulatory approach for these substances and substance groups in GB. They will determine the use profile in GB for each substance and substance group, whether any of these uses are creating a risk to human health and/or the environment and will identify the best regulatory approach to manage any identified risks.

As part of this call for evidence we would also like to know if you are willing to be contacted by HSE and the Environment Agency to discuss information that you have submitted.
