Description of key information

The density of the substance is 0.99 g/cm3 at 20°C

Key value for chemical safety assessment

Relative density at 20C:

Additional information

A literature review was conducted. In a weight of evidence approach the literature values were evaluated. Four independent literature sources (HSDB, REAXYS, GESTIS database and Yaws' Handbook of Physical Properties for Hydrocarbons and Chemicals) reports that the density of propionic acid is in a range from 0.99 g/ml to 0.993556 g/ml liquid at 20 °C.

The value from GESTIS was chosen as key parameter for the density.
