Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Biodegradation: Readily biodegradable but failing the 10-day window
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable but failing 10-day window
Additional information
Ready biodegradability has been determined with a non adapted activated sludge in the Modified Sturm test. The substance reached the 10% level (beginning of biodegradation) after 9 days. The test item did not reach the 60% pass level within the 10-day-window, but after 24 days. The substance is regarded, as a minimum, as inherently biodegradable and can be regarded as readily biodegradable though failing the 10 -day window criterium..
With adapted sludge, primary degradation in excess of 99% occurred over 28 days and ultimate degradation, measured as CO2 evolution, was 76% after 28 days.
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.
