Description of key information
Not readily biodegradable according to OECD criteria.
Key value for chemical safety assessment
Additional information
A study was performed according to OECD guideline 301 B (RCC Ltd. 2002b). At a concentration of the test substance of 23 mg/l, 3.7% were biodegradable within 28 days. It is assumed that the test compound was not fully solubilized in water. The results show that the compound is not readily biodegradable. In the toxicity control, no inhibitory effect on activated sludge microorganisms was observed.
This result is supported by the result from a MITI test (Institute of Ecotoxicology Ltd., Japan 2003, OECD 301C, biodegradation: ≤ 2% after 28 d). Therefore, the test substance is considered as poorly biodegradable.
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.
