Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 test substance is poorly biodegradable in terms of OECD criteria and poorly eliminated from water
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
In a study conducted for Dow Elanco in 1998 the ready biodegradability of the test substance was assessed according to OECD 301 F. Biodegradation was not observed during the test period. In a DOC Die Away-Test accroding to OECD 301 A (Hüls AG, 1997) a biodegradation degree of 18% was measured after 28 d indicating that the chemical is not readily biodegradable.
In a MITI test (1992) resembling the test guideline OECD 302 C demonstrated the absence of inherent biodegradation. Further, an OECD 302 B BASF-study from 1981 demonstrated a low potential for elimination from water.
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.
