Description of key information
The acute toxicity of Hydratropic Ald DMA to Daphnia magna was determined in a 48-hour static test according to the OECD 202 and following GLP. In this study, groups of Daphnia magna (4 replicates of 5) were exposed to 0.0, 6.25, 12.5, 25.0, 50.0 and 100 mgL. Nominal target concentrations were analytically verified, and mean measured exposure concentrations determined to be 6.21, 12.5, 23.6, 47.6, and 95.1 mg/L, i.e., 94 to 100% of the targeted nominal concentrations. Immobility of daphnids was recorded after 24 and 48 hours exposure. The test is valid. After 48 hours exposure, no effect on mobility was observed up to and including the test concentration of 100 mg/L.The 48-hour EC50 was determined to be ≥100 mg/L based on nominal concentrations, because analytical concentrations were 90 -100% of nominal.

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.
