Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 (OECD 301 F; GLP).
Additional information
Due to the information available from an experimental study according to OECD 301F performed compliant with GLP it is concluded that the substance is not readily biodegradable (0% biodegradation within 28 days based on ThOD).
Comparing the absolute oxygen demand measured in inoculum controls (n=2) with test item flasks (n=2) during days 1 to 15, pronouncedly lower values are found in the presence of test item (ca. 103 mg/L initial concentration). This may indicate microorganism toxicity of the test item at the concentration applied. As such, lack of biodegradability due to microorganism toxicity of the test item under the conditions of this test cannot be excluded.
No further tests on biodegradability are available for the test item.
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.
