Additional information

In the Klimisch 1 GLP study from Kimmel (2013) the acute toxicity of Sodium di(1.3-dimethylbutyl) sulfosuccinate to Daphnia magna was determined in a static limit test according to EEC C.2 and OECD 202. The test was started with a control and a nominal concentrations of 100 mg test item. The concentrations were analyzed by HPLC analyses. The mean measured concentrations were 0 (control) and 88 mg/L for the nominal concentration of 100 mg/L at the start and end of the exposure. Since all values were > 80 % the results were based on nominal concentrations. For each test concentration and the control, 4 replicates with 5 daphinds each were set up in 100 mL vessels filled with 50 mL test solution. After 48 hours of exposure no immobilization was observed in the control and the 100 mg/L test solution. The corresponding 48 h EC10 and EC50 value are > 100 mg test item/L.

This study is considered to be acceptable for the risk assessment.
