Additional information
A GLP-compliant OECD 202 guideline study with Daphnia magna is available forPolyol IXOL M125 (Solvay Duphar B.V., 1992c). Daphnids (30/dose) were exposed to nominal concentrations ranging from 15 to 1,000 mg/L under static conditions for 48 hours. The test concentrations were analytically verified andwere within 80% of nominal concentrations. No immobilisation was observed in the control and the lowest concentration during the test (0.63 mg/L). The percentage of immobile daphnids increased from 10% at 1.4 mg/L to 100% at 29 and 67 mg/L.No immobilisation exceeding 10% was observed during the test in any test concentration. A few water fleas were floating on the surface at 48 hours of exposure which was regarded not compound related. No other effects were observed.The 48-h EC50 value is >1,000 mg/L (based on nominal concentrations).
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.
