Description of key information

The density of a concentrated aqueous solution of lactic acid (as manufactured) is ca. 1.2 g/cm³.

Key value for chemical safety assessment

Relative density at 20C:
1.2

Additional information

Density of a concentrated solution of lactic acid depends on the concentration and temperature, but also on the degree of (spontaneous, reversible) polymerisation of lactic acid. The density at maximum purity of concentrated aqueous lactic acid is ca 1.2 g/cm³.
