Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- 110 mg/L
Additional information
The key study for this endpoint was a 48 hour static study using Daphnia magna and analytical verification of the exposure concentrations. In that study the EC50 was deterined to be > 110 mg/L based upon geometric mean measured concentrations. No immobility was observed in any of the exposure concentrations up to and including 110 mg/L (mean measured). These results are supported by a pre-GLP 48 hour study using nominal concentrations of 100 and 1000 mg/L of the test substance. The 48 hour EC50 from that study was > 1000 mg/L.
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.
