Additional information
Cyclohexyl methacrylate was tested in an acute toxicity study with Danio rerio under flow through conditions with analytical monitoring (FHI for Evonik Roehm, 2001). The test procedure followed OECD guideline 203. Nominal exposure concentrations were 100, 500 and 1000 mg/L. Since the test substance permanently dosed to the vessels tended to form a lipophilic phase at the water surface after 24 hours, samples for analytical monitoring were then taken from two different heights. The measured concentrations were not significantly different between different dose levels although dosage differed by one order of magnitude, whereas in all vessels the two depths were measured with concentrations differing by a factor of 20-40. Based on nominal test concentrations the 96-hour LC50 was determined to be 590 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.
