Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Two studies are available from the migrated NONS file provided by ECHA. One shows a 48h EC50 of 19.1 mg/L. The other shows the 24h EC50 to be 34.15 mg/L and the 48h EC50 to be 12.17 mg/L. The 48h NOEC was found to be 6.25 mg/L. The 48h test is the guideline study duration and therefore the worst case value of 12.17 mg/L is taken as the endpoint.
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.
