Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
2.755 ± 0.100 mg/l,at 20 °C and pH 7.1
Key value for chemical safety assessment
- Water solubility:
- 2.755 mg/L
- at the temperature of:
- 20 °C
Additional information
The solubility of the substance in water was determined from the measured concentrations of calcium in the filtrated test solutions.
The solubility range for the tested nominal concentration 1 –100 mg/l (flasks 1 – 4) is 1.003 – 2.859 mg/l test item at 20.0 ± 0.5 °C, corresponding to 36.6 – 1.0 % of dissolved Ca relating to the nominal concentration of the test item. The plateau of the solubility of Ca seems to be reached in 100 mg/l nominal load as the measured values of dissolved Ca in 10 mg/l and 100 mg/l nominal loads were comparable.
Therefore, the mean value from the flasks 1, 3 and 4 was stated as the water solubility of the test item: 2.755 ± 0.100 mg/l, at 20 °C and pH 7.1.
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.
