Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Two key studies and three supporting studies showed that the nominal LC50 value is clearly above 100 mg ai /L. In one key study a NOEC of 100 mg ai /L is reported, in the second key study a NOEC of 1500 mg/L is reported. This is supported by the results of the two supporting studies. In these studies NOEC values of 500 and 1000 mg/L was shown.
All these values are above the measured water solubility. Due to the testing substance is a surfactant, the critical micelle concentration (CMC) was chosen for the determination of the water solubility. CMC which is taken as solubility limit is 53.3 +/- 3 mg/L at 20°C.
NOEC is above the water solubility.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
