Description of key information
The test substance is not readily biodegradable according to OECD criteria.
Key value for chemical safety assessment
Additional information
The biodegradability of the substance was tested for 28 days at concentrations of 10.3 and 20.2 mg/L using of Tween 80 as an emulsifier in a GLP-guideline study according to OECD 301B (CIBA-GEIGY Ltd. 1992). Aniline and water with inoculum containing 3.0 mg/L TWEEN 80 were tested as reference substance and blank. In the concentration of 10.3 mg/L 71 % degradation was found within 28 days but failing the 10-day window. At a concentration of 20.2 mg/L 7 % degradation was measured within 28 days. Therefore, the test substance is not readily biodegradable according to OECD criteria.
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).
