Additional information
The chronic toxicity of Ceraphyl 55 to the Cladoceran (Daphnia magna) was determined in a GLP-compliant, 21 day flow-through study following OECD guideline 211 (Wildlife International 2008). The study exposed Daphnia magna to mean measured concentrations of 0.011, 0.023, 0.047, 0.096 and 0.185 mg Ceraphyl 55/L alongside a solvent control and blank control.
