Description of key information
The vapour pressure of lactic acid at room temperature is negligible (0.038 hPa, worst-case from two QSAR calculations).
Key value for chemical safety assessment
- Vapour pressure:
- 0.038 hPa
- at the temperature of:
- 25 °C
Additional information
Pure, crystalline lactic acid has an estimated vapour pressure of 0.0286 mm Hg (worst-case from two QSAR calculations). The vapour pressure of a 93% aqueous solution of lactic acid will be dominated by the vapour pressure of the water present in the solution, up to the boiling point of the solution.
For details and justification of read-across please refer to the read-across report attached to IUCLID section 13.
