Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Weight of evidence approach based on peer-reviewed handbook values (highly soluble, 5480 g/L; miscible). Taking its hygroscopic properties into consideration, it is concluded that phosphoric acid is miscible with water. 

Key value for chemical safety assessment

Water solubility:
1 000 g/L
at the temperature of:
20 °C

Additional information

Phosphoric acid is miscible with water; therefore it was concluded that the water solubility is greater than 1000 g/L at 20°C.

Value used for CSA: 1000 g/L at 20°C.
