Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The test item must be regarded to be not readily biodegradable after 28 days. No primary biodegradation/elimination was determined at test end in a study according OECD 301 C.
Based on the residue analysis, biodegradation of the test substance was 30.8% in the “test” vessel during the testing period. The BOD results showed that biodegradation of the test substance was 41.2% after 28 days in an inherent study according OECD 302 C.
Therefore under the test conditions of both studies (OECD 301C and OECD 302C) the pass level was not reached. The test substance is not readily biodegradable and not inherently biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed

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.
