Description of key information
Two screening studies for ready biodegradability were carried out. In the key study from Clarke (2003) (OECD TG 301B), the activated sludge was exposed to 10 mg C/L of the test substance. After 28 days of exposure, 2% of the test substance was biodegraded. Therefore, the test substance cannot be considered to be readily biodegradable under the strict terms and conditions of an OECD TG 301B.
Additional information
The second test was carried out according to OECD TG 301B and Guideline SEPA, P. R. China No. 301B. The degradation after 28 days was 1.63%. It is concluded that under the stringent conditions of this test no biodegradation is observed. As the conditions of the second study were less well described, this study is used as a supporting study.
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.
