Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Although tetrairon tris(pyrophosphate) is of low water solubility, a portion of the molecule may dissociate to (or be actively degraded to) orthophosphate (via pyrophosphate) and ferric (Fe3 +) ions in aqueous and biological systems. In order for ferric ions to be bioavailable they must be reduced to ferrous (Fe2+) ions.
Iron and orthophosphate ions are essential micronutrients for plants and animals; they stimulate the growth of water plants (macrophytes) and/or algae (phytoplankton) and are ubiquitous in the environment. Iron and phosphorus (from phosphates) metabolism is homeostatically regulated and as such the potential for bioaccumulation is considered to be minimal.
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.
