Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on available biodegradation screening studies, the substance is considered as inherently biodegradable.
Further biotic degradation testing has not been conducted. In accordance with REACH Annex IX column 2, simulation tests in surface water, sediment and soil are not considered necessary as the chemical safety assessment according to Annex I gives safe risk characterization ratios at the regional scale. Therefore half-life data from simulation tests is not required to further refine the environmental risk assessment.
Identification and/or the assessment of degradation products is not required. The structures of the most probable breakdown products from the process of biodegradation have been predicted using a valid QSAR-expert system. All predicted metabolites are more polar than the parent and are expected to be less toxic to the aquatic environment. Moreover for PBT/vPvB assessment purposes, both the parent and breakdown products have log Kow values which are below the B screening criterion of > 4.5. Thus no further assessment of the degradation products is warranted.
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.
