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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable
Additional information
The ready biodegradability of the test
item was assessed over a 28 day period by the modified Sturm test (OECD
301B). The nominal test concentrations were 10 and 20 mg a.s./L. The
test material attained up to 11 and 7 % biodegradation after 28 days
whereas the positive control substance (Aniline) was 94.4 % degraded 28
days. These results indicate that the test item cannot be classified
readily biodegradable under conditions of the test.
The inherent biodegradability of the test item was assessed over a 28
day period by the modified Zahn-Wellens Test (OECD 302B). The nominal
test concentrations was 10 mg a.s./L. The test material attained up to
60 % biodegradation after 28 days whereas the positive control substance
was 100 % degraded after 27 hours. These results indicate that the test
substance is inherently biodegradable in this test when measured by
specific analysis.
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.
