Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key value for chemical safety assessment
Additional information
According to Regulation (EC) 1907/2006, Annex IX, Section 9.2.1.3, Column 2, soil simulation testing does not need to be conducted if the substance is readily biodegradable.
The substance is not readily biodegradable according to OECD criteria. However, it is biodegradable based on an enhanced ready biodegradability test passing the test level of 60% CO2/ThCO2 but not meeting the 10-day window (OECD 301B, prolonged duration; BASF SE, 2012; see IUCLID Ch 5.2.1). In accordance with REACH Guidance document R.11 (ECHA, 2017: Table R.11-4, Figure R.11-3), substances which meet the pass level for ready biodegradability in enhanced ready biodegradation testing without the 10-day window are regarded as not P/vP. Further information for the assessment of non-persistence or persistence is not required. As this is the case for 1,2-dimethylimidazole, no soil simulation testing will be performed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
