Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key study: Test method according to OECD Guideline 301F. GLP study. At the 28th day of the test the aerobic biodegradation of the testing item was 0%. The substance cannot be deemed to be readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Key study: The study of ready biodegradability of test substance in aerobic aqueous medium with manometric respirometry method was carried out in accordance with OECD Guideline 301F and EU Method C.4-D (GLP study). 30 mg/L of activated sludge were exposed to 100 mg/l of test item during 28 days under aerobic conditions at 22 ºC. At the 28th day of the test the aerobic biodegradation of the testing item was 0%. The substance is therefore, not readily biodegradable under test conditions. In the toxicity test, containing both the test item and a reference item less than 25% of biodegradation (12.6% based on ThOD) occurred in 28 days and the test item probably can be assumed to be inhibitory.
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.
