Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
One key study and three supporting studies showed that the nominal LC50 value is clearly above 100 mg ai /L. In the key study a NOEC of 100 mg ai /L is reported, This is supported by the results of the supporting studies. In these studies NOEC values of 500 1000 and 1500 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 26 mg/L at 20°C.
NOEC is above the water solubility.
Key value for chemical safety assessment

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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
