Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The determination of biodegradation was evaluated on the substance itself, based on BOD5 and COD.
The BOD5 test is a traditional biodegradation test that is now replaced by the ready biodegradability tests.
Therefore, this test should not be performed today for assessment of the read biodegradability of substances. Older test data may, however, be used when no other degradability data are available.
Other data are available on a similar substance, a modified ZAHN-WELLENS-Test (OECD 302B) and a BOD5 and COD tests.
Results revealed that the similar substance 01 is inherently biodegradable based on the ZAHN-WELLENS-Test (OECD 302B) outcome, but non-readily biodegradable.
Based on the criterion BOD5/COD ≥ 0.5, the substance itself and the similar substance 01 are resulted not biodegradable.
Based on the QSAR and data evaluation on the substance itself, and the Read Across principle, the substance can be considered not readily biodegradable. Justification for Read Across is detailed in the report attached to the IUCLID section 13.
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.
