UK REACH to Distinguish Itself from Predecessor

By: SiliconExpert on January 18th, 2022

January 18, 2022 – UK’s REACH regulation, under the guidance of the Health & Safety Executive (HSE), has made its first steps towards distinguishing itself from EU REACH. 

The HSE’s recommendation to add two new substances is one of the first clear signs of the divergence from its EU Predecessor. The UK Registration, evaluation, authorization & restriction of Chemicals regulation, (otherwise known as REACH) was implemented in the UK following its separation from the European Union in 2018.  

Effective, January 1, 2021, the UK REACH and EU REACH programs began operating independently of each other, thus requiring companies that operate in both the EU and the UK to ensure that the relevant actions are taken to fall within the guidelines of both pieces of legislation. 

SiliconExpert has compiled below a list of the new substances selected for inclusion in the UK REACH’s national authorization list. 

EC NumberCAS Number
Dicyclohexyl phthalate (DCHP) 201- 545-9 84-61-7
Disodium octaborate 234- 541-0 12008- 41-2

The application date for both materials is January 2023 with a sunset date of 18 months after the application date.   The goal of the authorization process is to ensure substances of very high concern (SVHCs) are replaced with less dangerous substances or technologies where alternatives exist.  

According to a statement from the Health & Safety Executive (HSE), “any substance that has been identified as an SVHC and included on the national authorization list (Annex 14) cannot be used or placed on the market after a specific date unless the use has been authorized or is exempt from authorization.”
