Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In consideration of water solubility and vapour pressure, Henry´s law constant is not relevant.

Key value for chemical safety assessment

Additional information

As substance "reaction mass of calcium hydrogen phosphonate and dialuminium tricalcium hexaoxide" is a sparingly soluble solid with an assumed vapour pressure of < 10exp-10 Pa at 25°C, volatilisation of the substance from aqueous solutions can be taken as not relevant, and thus Henry´s law constant is assessed as not relevant.
