Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Methodological deficiencies in five supporting studies rendered the results unreliable. However, a modern GLP investigation found no evidence of acute toxicity to Daphnia magna and the NOEC was 1000 mg/L when expressed in terms of loading rate.
A further value of 2.38 mg/L was derived from the results of calcium analysis as surrogate for test material however this value was not reliable enough to use in hazard 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.
