Additional information
24 hour static test with vehicle (OECD 202):
In a GLP guideline study according to OECD 202, no EC50 for Daphnia magna could be determined. The test daphnids were at the surface of the test water, particularly in lower test concentrations. Their immobility was affected by deposits of test substance on the body of the animals. This might explain part of their immobility and the lack of a clear dose/effect relationship.
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.
