Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 readily biodegradable (20% mineralization within 28 days).
Additional information
Only screening-type information on biodegradation is available for the test item.
The ready biodegradability was investigated in a reliable study conducted according to the OECD guideline 301 B (Modified Sturm Test; adopted 1981) and EEC Commission Directive 84/449/EEC C.5, and was performed in compliance with GLP (Hüls, 1991).
The study was performed under aerobic conditions using activated domestic sludge as inoculum. The study included two treatment groups of test item concentrations of nominal 10 mg/L and 20 mg/L, an inoculum control and a system control (reference substance sodium benzoate). The percentage biodegradation was measured with respect to CO2 evolution in the course of 28 days. After 28 days, the test substance reached a level of mineralization of 20% (10 mg/L) or 21% (20 mg/L). As the amount biodegradation was below 60%, the test item could not be considered readily biodegradable under the given test conditions.
The study fulfilled the validity criteria of the guideline, and the obtained results were considered reliable.
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.
