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.
