Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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, OECD 301F, Manometric respirometry test, Magor 2000
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The test substance was investigated for its ready biodegradability in a manometric respirometry test over 28 days based on OECD Guideline 301F and in accordance with GLP (Magor 2000). The chemical oxygen demand (COD) of the test substance was determined to be 0.866 g O2/g test material. The biochemical oxygen demand (BOD) was determined to be <0.05 g O2/g test material during the whole experimental period. The biodegradation after 28 days was determined to be <5%. The biodegradation of the reference substance (sodium acetate) was 58% after 5 days and 64% after 10 days. On the basis of the screening test results, the test substance is considered as not readily biodegradable.
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.
