Additional information
The toxicity of Sodium methyl cocoyl taurate to aquatic microorganisms was determined according to the principles of OECD 209 (Fiebig, 2012). Test system was activated sludge of a municipal treatment plant. The test was carried out under static conditions with the following test substance concentrations 100, 180, 320, 560 and 1000 mg/L. The respiration rates of the control, reference and test item replicates were measured after a contact time of three hours. The NOEC andEC50 of the test item Sodium methyl cocoyl taurate was determined as 180 mg/L and 513 mg/L, respectively.
