Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
OECD Guideline 301D, GLP, key study, validity 1:
77% biodegradation after 28 days within the 10 day window.
Readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
One valid key study is available to assess the biodegradation potential of the registered substance. This study was performed according to OECD Guideline 301D with GLP statement. The substance was exposed to river water at a concentration of 2 mg/L with culture medium in closed bottles in the dark at 22-24 °C for 7, 14, 21 and 28 days. The degradation of the substance was assessed by the measurement of oxygen consumption.
The test substance attained 77% degradation after 28 days and satisfied the 10 day window validation criterion. Therefore the registered substance can be considered to be readily 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.
