Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
- BCF (aquatic species):
- 43 dimensionless
Additional information
Aluminium dihydrogen triphosphate is an inorganic phosphate and will dissociate aluminium and triphosphate ions and further hydrolysed forming various aluminium species and soluble orthophosphate (PO43-) in sewerage systems, sewage treatment plants and in the environment.
The phosphate anion (PO43-) is ubiquitous in natural waters and essential micronutrient for many organisms, it will not bioaccumulate in organisms and food chains.
The bioaccumulation potential of aluminium dihydrogen triphosphate (CAS 13939-25-8) was tested in a GLP guideline study according to OECD 305 under the flow-through conditions. The stock solution of the test item was prepared using sodium polyacrylate as dispersant. Test fish (Cyprinus carpio) were exposed to test concentrations of 4.735 mg/L and 0.4735 mg/L respectively. The test was terminated after 28 days. At a substance concentration of 4.735 mg/L a BCF value ≤ 43 was determined, whereas a BCF ≤ 4.8 was determined at a test substance concentration of 0.4735 mg/L.
The study results demonstrate that the potential of aluminium dihydrogen triphosphate (CAS 13939-25-8) to bioaccumulate and the risk of secondary poisoning are low.
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).
