Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Additional information
The substance was not shown to be readily biodegradable in a closed-bottle test. However, the substance was shown to be rapidly biodegradable in the environment under aerobic conditions at environmentally-relevant concentrations. A soil simulation biodegradation study reported mineralization of 70.7% in 28 days and 80.8% in 121 days; the DT50 for the substance (i.e., the parent compound) and its primary metabolite (i.e., Metabolite II) were reported as 9.7 days and 3.5 days, respectively. The experimentally-determined rapid degradation in soil is sufficient documentation for showing rapid degradation in surface water and sediment, in accordance with ECHA guidance (Guidance on the application of the CLP criteria, Version 3.0, November 2012, Section II.2.3.6, p. 498).
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.
