Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- inherently biodegradable
Additional information
One study investigated the biodegradation of the test substance in a screening test (Clarke, 2006) according to the OECD Guideline 301 D “Closed Bottle Test”. The test substance was biodegraded to 46% (mean) after 28 days. Therefore, it is not readily biodegradable according to the OECD criteria. However, investigations on the inherent biodegradability according to the OECD Guideline 302 B “Inherent Biodegradability: Zahn-Wellens/EVPA Test“ (Muckle, 2010) demonstrated that the test item will be almost completely biodegraded in a biological wastewater treatment system and is considered to be inherently biodegradable (97% after 14 days). From the results of the screening test for ready biodegradability and the result from the inherent biodegradability study it can be concluded that the substance will not be persistent in the environment.
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.
