UK REACH Authorisation List: disodium octaborate

Page 1 of 14

Closes 12 Aug 2022


The Health and Safety Executive (HSE) recommends priority substances for inclusion in the Authorisation List from the UK REACH Candidate List of substances of very high concern (SVHCs). Substances added to the Authorisation List cannot be used or placed on the market in Great Britain without prior authorisation after the specified sunset date. Dicyclohexyl phthalate and disodium octaborate are both listed on the UK REACH Candidate List.

For further information on these substances and why we are considering adding these substances to the Authorisation List, see HSE’s recommendation, including the background document for these substances. This Call for Evidence is focused on addressing uncertainties and data gaps relating to that recommendation, especially in respect of how those substances are used in Great Britain and the social and economic impacts of adding them to the Authorisation List.

HSE held a three month public consultation on their draft recommendation where they sought information and evidence on the technical aspects of their recommendation. We are not intending to re-run or duplicate that exercise.

We are also running a parallel Call for Evidence relating to dicyclohexyl phthalate that is available at:
