Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A study has been performed in accordance with EU Method C7. 

Key value for chemical safety assessment

Additional information

Hydrolysis is not an appropriate degradation pathway for disodium fluorophosphate. On contact with aqueous solutions disodium fluorophosphate will dissociate to sodium and fluorophosphate ions. The fluorophosphate ion has no potential mechanism for further hydrolysis as demonstrated in the key study (half life of the fluorophosphate anion is >1 year). It is considered that degradation would occur in biotic systems via the action of phosphatases which would liberate the phosphate and fluoride ions.
