Description of key information
The 48-Hour EC50 for the test item to Daphnia magna based on nominal concentration was 1340 mg/L. The nominal NOEC of the test item is 100 mg/L. EC50 values are above the 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.

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.
