Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
not biodegradable (< 1% biodegradation, CO2-evolution test, OECD 301B)
Key value for chemical safety assessment
Additional information
In order to determine the ready biodegradability of the test substance a CO2-evolution test conducted by Muckle (2014). The study was conducted according to GLP and followed OECD guideline 301B. Activated sludge as inoculum was exposed for 28 days. A concentration of nominally 20 mg organic carbon/L corresponding to 28.3 mg of the test substance was used. No degradation could be observed after 28 days. Degradation behaviour of positive control and toxicity control was normal. Abiotic degradation was not observed. Thus, the test substance cannot be considered as biodegradable.
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.
