Description of key information

EC50 (72h) = 79 mg/L; NOEC = 9.2 mg/L for Desmodesmus subspicatus (OECD 201)

Key value for chemical safety assessment

EC50 for freshwater algae:
79 mg/L
EC10 or NOEC for freshwater algae:
9.2 mg/L

Additional information

Toxicity of Sodium N-lauroylsarcosinate (CAS 137-16-6) to aquatic algae was investigated in an algal growth inhibition test with Desmodesmus subspicatus according to OECD guideline 201 and GLP (Vryenhoef and Mullee, 2010). The test revealed an EC50 (72h) of 79 mg/L (nominal) based on growth rate and 39 mg/L (nominal) based on yield. The NOEC was found to be 9.2 mg/L.
