Description of key information
Not readily biodegradable according to OECD criteria.
Key value for chemical safety assessment
Additional information
An GLP-guideline study on ready biodegradability according to OECD 301 B was conducted (RCC 2007). After 28 d no biodegradation of the test item was observed. Based on this result, the test substance is considered as poorly biodegradable. Additional, results on an OECD 303 A study are available using 20 mg/L as TOC of the test item (Ciba-Geigy, Dyestuffs and Chemicals Division 1990). After 21 days the mean value of elimination was 88 % TOC. However, only limited information (one-page summary) is given and no statement about GLP.
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.
