Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to the key biodegradation study (OECD Guideline 301F, EU Method C.4-D, EPA OPPTS 835.3110, GLP), the registered substance is not readily biodegradable (2% biodegradation after 28 days). In the prolonged test, only 3% biodegradation after 60 days was observed. Based on analytic assessment, the recovery of the test substance at the end of test was only to 5% (so 95% loss over the test duration assuming 100% recovery on day 0). An hypothesis would be the result of a primary biodegradation of the test substance and therefore a total loss of the parent compound. However, in the absence of other studies, the registered substance can be considered potentially Persistent (P) or very Persistent (vP) in the environment.

Additional information

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.
