The next batch of GB MCL technical reports is now available. A GB MCL technical report is an independent scientific evaluation of the information submitted under the stand-alone GB MCL process or as part of the EU harmonised classification and labelling process. It sets out whether there is adequate scientific evidence to support a new or revised GB MCL of a substance and what that GB MCL should be. Download the next batch of technical reports at the end of the GB MCL publication table. These GB MCL technical reports relate to substances for which the Committee for Risk Assessment (RAC) published a RAC Opinion under Article 37(4) of EU CLP during 2024, based on information submitted under the EU CLP Regulation. The scientific information supporting the RAC Opinion is evaluated under the GB MCL system. At the time of publication, the classification and labelling proposed in these technical reports has not been agreed and/or adopted in GB. For information on the next steps in the process, please see our webpage on the GB MCL system. We expect to publish our next batch of technical reports in September 2025. CLP ebulletin alerts will be issued when technical reports are published on the HSE website. If you have any questions or feedback on the GB MCL technical reports, please contact us via email. Journalists should contact HSEâs press office for further information. The European Chemicals Agency (ECHA) has announced public consultations. The GB MCL process includes the consideration of information gathered from public consultations, conducted by HSE or international bodies such as ECHA. ECHA has announced public consultations on the following proposals for harmonised classification and labelling (CLH): Deadline: 25 July 2025 di(morpholin-4-yl) disulphide (EC: 203-103-0; CAS: 103-34-4). Chemical registered under REACH. Human health hazard classes open for commenting N,N'-hexane-1,6-diylbis[2,2-dimethyl-3-(morpholin-4-yl)propan-1-imine] (EC: -; CAS: 1217271-49-2). Chemical registered under REACH. Human health hazard classes open for commenting N-[3-({[2,2-dimethyl-3-(morpholin-4-yl)propylidene]amino}methyl)-3,5,5-trimethylcyclohexyl]-2,2-dimethyl-3-(morpholin-4-yl)propan-1-imine (EC: -; CAS: 1217271-02-7). Chemical registered under REACH. Human health hazard classes open for commenting sodium trifluoroacetate; [1] and other inorganic salts of trifluoroacetic acid [2] (EC: 220-879-6 [1]- [2]; CAS: 2923-18-4 [1] - [2]). Chemical registered under REACH. Human health hazard classes and PBT/vPvB open for commenting Trifluoroacetic acid (EC: 200-929-3; CAS: 76-05-1). Chemical registered under REACH. Human health hazard classes and PBT/vPvB open for commenting
View the consultation on the ECHA website.
UK-based businesses with an interest in the proposal are strongly encouraged to share any relevant information. Scientific and technical information should be submitted directly to ECHA using their commenting webform by 25 July 2025. 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 proposals. 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 GBCLP.GBMCL@hse.gov.uk. 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. |
