  • 2,2-Bis(bromomethyl)propane-1,3-diol (BMP); 2,2-dimethylpropan-1-ol tribromo derivative/3-bromo-2,2-bis(bromomethyl)-1-propanol (TBNPA); 2,3-dibromo-1-propanol (2,3-DBPA)
  • 2-(4-tert-Butylbenzyl)propionaldehyde and its individual stereoisomers (Lysmeral)
  • 2-(Dimethylamino)-2-[(4-methylphenyl)methyl]-1-[4-(morpholin-4-yl)phenyl]butan-1-one (Omnirad)
  • 6,6′-Di-tert-butyl-2,2′-methylenedi-p-cresol (DBMC)
  • 6-[(C10-C13)-alkyl-(branched, unsaturated)-2,5-dioxopyrrolidin-1-yl]hexanoic acid (Tetra-PSCA)
  • Barium diboron tetraoxide
  • Bis(2-(2-methoxyethoxy)ethyl) ether (tetraglyme)
  • Bis(α,α-dimethylbenzyl) peroxide
  • Dioctyltin dilaurate, dioctyltin bis(cocoacyloxy) derivatives, and other dioctyltin bis(fatty acyloxy) derivatives (DOTL)
  • Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide
  • N-(Hydroxymethyl)acrylamide
  • Orthoboric acid, sodium salts
  • Reactive Brown 51
  • Tris(2-methoxyethoxy)vinylsilane

This new decision was taken following the public consultation process launched by the HSE on 9 March 2026. After the process ended on 20 April, the substances concerned were identified as SVHCs and added to the Candidate List. Click here to review the updated Candidate List.

The HSE has also announced that further consultations will be carried out for additional SVHC substances. Companies are advised to follow the HSE e-bulletin.

What Are the Obligations Relating to These Substances?

Under UK legislation, companies must fulfil certain information and notification requirements where substances included in the Candidate List are present in the products they supply.

  • Where a substance included in the Candidate List is present in an article at a concentration above 0.1% (w/w), the necessary information for the safe use of the article must be provided to the recipient.
  • Where articles containing substances included in the Candidate List are produced, imported or placed on the market, a notification to the HSE may be required if certain conditions are met. In addition, information obligations also apply to mixtures that are not classified as hazardous under the GB CLP Regulation but contain a Candidate List substance. Where a mixture contains a Candidate List substance at a concentration of 0.1% or above, a safety data sheet (SDS) must be provided upon request.
  • Furthermore, where a substance placed on the market is included in the UK REACH Candidate List, the supplier is required to provide the customer with the safety data sheet for the relevant substance.

These obligations aim to ensure that Candidate List substances are managed transparently throughout the supply chain and that safe use information is communicated to the relevant parties.
