Additional information

The toxicity of Sodium N-lauroylsarcosinate (CAS 137-16-6) to microorganisms was investigated in one study according to OECD 209 and GLP. Domestic activated sludge was used in the test which included a valid reference control. The maximum inhibition of microbial respiration was 18% at 1000 mg/L which was the highest concentration tested. Therefore the EC50 (3 h) was reported to be > 1000 mg/L (30% aqueous solution) and the NOEC (3 h) was 100 mg/L (30% aqueous solution) and 30 mg/L (100% calculated).
