NOEC (3h) 30 mg/L (OECD 209, 100% calculated)
Key value for chemical safety assessment
- EC50 for microorganisms:
- 30 mg/L
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).
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.
