ECHA public consultation: call for comments


Deadline: 8 April 2022

The Great Britain Mandatory Classification and Labelling (GB MCL) process includes the consideration of information gathered from public consultations, conducted by HSE or international bodies such as the European Chemicals Agency (ECHA).

ECHA has announced a public consultation on the following proposals for harmonised classification and labelling (CLH):

dibenzoyl peroxide; benzoyl peroxide (EC: 202-327-6; 94-36-0). Chemical registered under REACH

reaction mass of 1,3-dioxan-5-ol and 1,3-dioxolan-4-ylmethanol  (EC: -; -). Chemical registered under REACH

View the details.

UK-based businesses with an interest in the proposals are strongly encouraged to share any relevant information. 


Scientific and technical information should be submitted directly to ECHA using their commenting webform by 8 April 2022. Comments will be published on ECHA’s website.

If your business is affected by the GB CLP Regulation, please also consider if you are likely to be affected by the classification and labelling proposal and let us know at an early stage if you anticipate any significant impacts or benefits. 

Information on wider policy and impact considerations can be submitted to HSE at

Under the GB CLP Regulation, HSE will consider all published opinions of the Committee of Risk Assessment of ECHA (RAC) before publishing its own Agency Technical Reports and Agency Opinions, so any information you provide will be important in any final GB MCL decision.

More information on the new GB MCL system is available on the HSE website.
