Description of key information

From the water surface the substance will not evaporate into the atmosphere. 

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 using the vapour pressure and the water solubility of 2-ethylhexanoic acid as input data. It is calculated to be 0.294 Pa*m³/mol (Hazardous Substances Database 2005)
