Description of key information

The water solubility of the substance is 1000 g/l at 25 °C.

Key value for chemical safety assessment

Water solubility:
1 000 g/L
at the temperature of:
25 °C

Additional information

A literature review was conducted. In a weight of evidence approach the literature values were evaluated.

HSDB and the SRC Physical Properties database database reports that propionic acid has a water solubility of 1000 g/l at 25 °C.

Ullmann and Knovel Solvents - A Properties Database reports that propionic acid is miscible in any ratio with water.

The value from HSDB which is a peer reviewed database was chosen as key parameter for the water solubility.
