Acutely toxic to fish.
Key value for chemical safety assessment
Additional information
The LC50 (96h) value of the test substance on rainbow trout was determined to be ca. 4.39 mg/L in a GLP flow-through study carried out according to OECD 203 (BASF AG 12F0231/985045, 1998, triethylene glycol was used as a vehicle). This result is supported by a LC50 (96h) between 2.2 and 4.6 mg/L which was determined in another GLP study according to OECD 203 (BASF AG 17F0244/925042, 1993, Tween 80 was used as a vehicle).
Based on these data the test substance is considered to be acutely toxic to fish.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
