Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
No daphniastudy (OECD 202) is available for the registered substance. The data gap, however, is brigded by read across to the stuctural very similar substance Sulfosuccinic (FA C12-18)E, 2Na.
In the Klimisch 1 GLP study from Kimmel (2013) (read across study) 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.This information is considered to be relevant and reliable for the further risk assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
