Description of key information
Not readily biodegradable according to OECD criteria.
Key value for chemical safety assessment
Additional information
The readily biodegradability of the test substance was tested in a GLP guideline study according to OECD 301 B (CIBA-GEIGY 1991a). 3 % biodegradation was observed after 28 d with the initial test concentration of 20 mg/L and 10 % biodegradation with the initial test concentration of 10 mg/L. The results are supported by a GLP guideline study according to OECD 301 C (Mitsubishi Chemical Safety Institute Ltd. 1994). No biodegradation was observed 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.
