Description of key information
The acute toxicity of the substance to Daphnia magna was determined in a study conducted according to OECD TG 202 and GLP. In this static test, groups of 20 daphnids were exposed for 48 hours to a nominal test substance concentration of 20 mg/L, a dilution water control and a solvent control. The test concentration was analysed at the start and the end of the test by gas chromatography using a flame ionisation detector. The mean measured concentration of the test substance was 70% of the nominal exposure concentration, and there was a 13% loss in measured concentration over the test period. On the basis of these analyses the mean of the measured test concentration value was used for the calculation of the biological results. No signs of immobilisation were noted throughout the 48-hour test period. Based on these findings, the EC50 was determined at >14 mg/L.

Additional information
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.
