Description of key information

With high probability acutely not harmful to aquatic plants.

Key value for chemical safety assessment

EC50 for freshwater algae:

EC10 or NOEC for freshwater algae:
31.25 mg/L

Additional information

In a non-GLP, 72-hour static test with the green alga Scenedesmus subspicatus (new name: Desmodesmus subspicatus) similar to German Industrial Standard DIN 38412 part 9, the algae toxicity of sodium sarcosinate was investigated. Statistical evaluation of the endpoint growth rate revealed an EC50 (72h) >500 mg/L, the NOEC was estimated to be 31.25 mg/L, both related to the nominal concentration.
