Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Two studies on biodegradability of the test substance are available.
The ready biodegradability of the test item was assessed over a 28
day period by the OECD Screening Test (OECD 301E). The test material
attained up to 44 % biodegradation after 28 days whereas the
positive control substance (Aniline) was 88 % degraded after 7 days.
These results indicate that the test item cannot be classified as
readily biodegradable under conditions of the test.
In the modified Zahn-Wellens test according to OECD 302 B the test
substance was tested for inherent biodegradation. After 28 days the
test substance was degraded to 61 % after 28 days, the reference was
degraded to 100 % in 27 hours. It was concluded that the test
substance is inherently biodegradable.
In addition, the chemical oxygen demand was determined to be 1.22 g
COD/g test substance in a 2 hour study. The chemical oxygen demand
of the reference substance potassium hydrogen phthalate was
determined to be 199.3 mg COD/L.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable
Additional information
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.
