Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The substance is not readily biodegradable under the conditions of the test.
Key value for chemical safety assessment
Additional information
The biodegradation potential of the substance in water was determined in a screening study according to OECD TG 301B (CO2 -Evolution Test) and in compliance with GLP criteria (BASF, 2015). In this study ca. 33 mg/L test substance (20 mg TOC/L) was inoculated with activated sludge from a municipal sewage plant for 28 days under aerobic conditions. During the incubation period degradation was followed by determining the carbon dioxide produced. After the 28 -day incubation period less than 10% of the test substance was biodegraded. Based on these findings, the test substance is classified as not 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.
