Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is not readily biodegradable according to OECD criteria but may be well eliminated from wastewater
Key value for chemical safety assessment
Additional information
Ready biodegradability was investigated in a non-GLP test according to OECD guideline 301E (BASF 1991). After 37 days of exposure no biotic elimination was observed but only 33% of abiotic elimination. This result is supported by the results of a non-GLP Zahn-Wellens-Test according to OECD guideline 302B also using domestic activated sludge as inoculum (BASF 1991). After 27 days 100% of the test substance was eliminated whereof 65% were eliminated abiotically. As abiotic elimination was not due to adsorption volatilization has to be regarded as a major elimination path in STPs.
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.
