The European Chemicals Agency (ECHA) has added ten substances of very high concern (SVHCs) to the REACH Candidate List, bringing the total to 191 substances.

Four of the substances: octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), dodecamethylcyclohexasiloxane (D6), and Bbnzo[ghi]perylene, were added due to their persistent, bioaccumulative and toxic (PBT) and very persistent and very bioaccumulative (vPvB) properties.

The fifth substance, terphenyl hydrogenated has been added for its vPvB properties.

In addition, ECHA added lead, disodium octaborate, and dicyclohexyl phthalate (DCHP) to the list due to their toxic for reproduction properties. DCHP is also included due to its endocrine disrupting effects on human health.

The remaining two- ethylenediamine (EDA) and benzene- 1,2,4‑tricarboxylic acid 1,2 anhydride (trimellitic anhydride) (TMA) were included for their respiratory sensitising properties.

These substances are candidates for possible inclusion of  REACH Authorisation process (Annex XIV), which means that companies using these chemicals will need to apply to ECHA for permission to use them (given there are not suitable alternatives).
