Additional information
The acute toxicity of Ceraphyl 55 to the Rainbow Trout (Oncorhynchus mykiss) was determined in a GLP-compliant, OECD guideline 203 study (Springborn Smithers 2004). The study exposed rainbow trout to mean measured concentrations of 0.0013, 0.0035, 0.0029, 0.0065 and 0.022 mg Ceraphyl 55/L alongside a solvent control and control samples. No concentration tested produced any mortality. Therefore the 96 hour LC50 was estimated as ≥0.022 mg/L, the highest mean concentration tested. The NOEC was determined to be 0.022 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.
