Additional information
To determine the toxicity of the test substance to aquatic invertebrates, a GLP study according to OECD guideline 202 and EU method C.2. Daphnia magna Straus (>24 hours old) were exposed to the test item in a static test for 48 hours at concentrations of 0 (control), 4.6, 10, 22, 46, 100, 220 mg/L based on the test substance density. Four replicates with five animals each were used for each concentration level. Based on the results no toxic effect in the range of water solubility was determined. The following effect concentrations were obtained based on nominal concentrations:
EC0 = 22 mg/L
EC50 = 161 mg/L
EC100 > 220 mg/L [BASF SE 2009]
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.
