Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Substance "reaction mass of calcium hydrogen phosphonate and dialuminium tricalcium hexaoxide" can be expected not to have a relevant potential for adsorption neither to organic nor to inorganic material. Data on partition coefficient n-octanol/water are not available as the substance is inorganic.
However, a measurement of solubility in standard fat HB 307 (< 6.8 mg/100 g at 37°C) and the data on water solubility (0.68 g/L) indicate on missing affinity to organic material or the aquatic compartment.
As the substance 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 as well.
Most probably, if released to the environment, the inorganic, sparingly soluble crystalline solid of lamellar clay mineral (hydrocalumite)-like substance will end up in the sediment or soil compartment by sedimentation comparable to natural clay minerals. This fate is not expected to result in any negative environmental impact (c.f. G.E. Batley and M.J. McLaughlin CSIRO Niche Manufacturing Flagship Report, Fate of Manufactured Nanomaterials in the Australian Environment, prepared for the Australian Department of the Environment, Water, Heritage and the Arts (March 2010), available via Internet https://www.environment.gov.au/system/files/pages/371475a0-2195-496d-91b2-0a33f9342a6d/files/manufactured-nanomaterials.pdf). Transformation by normal environmental processes (e.g. diagenesis or dissolution) is not expected to result in any negative environmental impact either, as the substance does only comprise of nonhazardous common environmental elements.
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.
