Additional information
One reliable study is available for the registered substance. The short term toxicity to aquatic invertebrates was studied according to OECD TG No. 202 and Test Method C.2 from Commission Regulation (EC) No. 440/2008. Daphnids were exposed to nominal test concentrations of 1.0, 1.6, 2.5, 4.0, 6.3 and 10 mg/L. The immobility of the daphnids was determined in a semi-static 48-hour test by visual observation after 24 and 48 hours. The concentrations of the test substance were determined by chemical analyses at the start, at 24 h (new and old solutions) and at the end of the test. The concentration of the test item was not satisfactorily maintained within ± 20% of the initial concentration throughout the test. Thus, the endpoint were based on the geometric means of the measured concentrations. The 48h-EC50 was determined to 4.63 mg/L.
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.
