Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Phosphoric acid, potassium salt (2:3), dihydrate has low bioaccumulation potential
Key value for chemical safety assessment
Additional information
According to Regulation (EC) 1907/2006, Annex IX, section 9.3.2, column 2, testing for this endpoint is not required if the substance has a low potential for bioaccumulation. Phosphoric acid, potassium salt (2:3), dihydrate is a simple, highly soluble inorganic salt that dissociates immediately in aquatic solutions. The main products of the dissociation of this substance in water are PO4-3 and K+ions. Both potassium and phosphate are essential elements and therefore, aquatic organisms posses internal mechanisms in order to regulate them. Based on this information, no risk of bioaccumulation and biomagnification is associated with phosphoric acid, potassium salt (2:3), dihydrate.
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.
