Description of key information
Additional information
Short term tests with species of three trophic levels are available. Aquatic invertebrates and fish were the most sensitive species, with acute toxicity values (L(E)C50) of 5.04 mg/L and 4.6 mg/L, respectively. Short term effects of the substance towards algae was markedly higher, showing an EC50 (72h) of > 100 mg/L.
A chronic test on aquatic invertebrates resulted in a NOEC for reproduction of 4 mg/L. Reliable chronic data on fish are not available for this substance, however the risk characterization ratio (RCR) has demonstrated that there is no indication of risk i.e. PEC/PNEC freshwater < 1 from current exposure conditions to this substance.
Based on a respiration inhibition test, Sodium methyl cocoyl taurate is regarded as not harmful to aquatic microorganisms. Consequently a disturbance in the biodegradation process of a sewage treatment plant is not anticipated for this substance, which is also supported by the ready biodegradability.
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.
