Description of key information

Simple calculation of vapour pressure divided by aqueous solubility gives a Henry's law constant of 0.26 Pa × m³/mol for ethyl-(S)-lactate.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
at the temperature of:
20 °C

Additional information

Henry's law constant was calculated from the vapour pressure and the water solubility. Ethyl-(S)-lactate is miscible with water. Accordingly, the solubility can be equated with the molarity of pure ethyl-(S)-lactate.
