Additional information

In the Klimisch 1 GLP study from Kimmel (2013) the acute toxicity of Sulfosuccinic (FA C12-18)E, 2Na on Daphnia magna was determined in an 48 hour static test according to OECD 202 and EU method C.2. The test was performed with concentrations of 6.25, 12.5, 25, 50 and 100 mg test item/L and a blank control. Four replicates with 5 daphnids each were set up. After 48 hours 0, 0, 0. 50, 100 and 100 % immobilization was observed in the control and at test concentrations of 6.25, 12.5, 25, 50 and 100 mg test item /L, respectively. Analytical measurements confirmed that the test solutions were correctly dosed and statble throughour the exposure period. Therefore the data were evaluated based on nominal concentrations. The EC50 is 13 mg as/L, the NOEC and EC0 is 6.25 mg test item/L.

The results are considered relevant and reliable for the risk assessment.
