Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Acute immobilisation to Daphnia has been investigated over a 48 hour period. Entrapment on the surface occurred at higher concentrations, regarded as beyond the water solubility of the substance. The EC50 was > 0.022 mg/L and a NOEC of 0.0195 mg/L was established.
A second study reports an EC50 of 15 mg/L. This concentration is in excess of the normal water solubility of the substance and was obtained by the use of solubilising agents.
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.
