Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Within 28 days, a degradation rate of 21 % was determined. The test item is considered to be "Not readily biodegradable".
Within 28 days a degradation of 81 % was determined according to the OECD Guideline 302 C. Therefore the test item is considered to be "inherently biodegradable".
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Inherent Biodegradation:
The amount of the substance could be on the experimental accompanying DOC analysis detected only in part. This is probably an immediate absorption of the biomass used. The eliminated by adsorption portion of the test substance was not taken into account in the calculation of the degradation.
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.
