Additional information
The acute toxicity of Ceraphyl 55 to Daphnia magna was determined in a GLP-compliant, static acute toxicity study following OECD guideline 202 (Springborn Smithers 2004). Twenty Daphnia were exposed for 48 hours to Ceraphyl 55 at mean measured concentrations of 0.0016, 0.0038, 0.0084, 0.012 and 0.028 mg/L alongside a solvent control and blank controls and observed for immobilisation and sublethal effects. Immobilisation was observed at the two highest test concentrations, and an EC50 calculated.
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.
