Description of key information
The influence of Reaction mass of sodium sulfate, sodium amino-12- dodecanoate and sodium dodecanoedioate on the growth of the freshwater green algae was assessed in a static dose-response test. The 72 hour EC50 value for the parameter growth rate could not be calculated due to the low inhibition of this parameter, for the parameter yield it was extrapolated to be 119.3 mg test item/L. The 72-hour NOEC was determined to be 3.2 mg test item/L for the parameters growth rate and yield, respectively. The associated 72-hour LOEC was determined to be 10 mg test item/L for the parameter growth rate for both parameters.
Key value for chemical safety assessment
Additional information
The acute toxicity of Reaction mass of sodium sulfate, sodium amino-12-dodecanoate and sodium dodecanoedioatewas evaluated withPseudokirschneriella subcapitatain a study performed in accordance with OECD testing guideline 201 and GLP requirements.

Temperatures, pH range and dissolved oxygen concentration were reported and in agreement with the guideline recommendations. Quality criteria were fulfilled.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
