Description of key information

The Henry's law constant was calculated from vapour pressure, molecular weight and water solubility according to the TGD, Part II. Based on the key study data for vapor pressure and water solubility, the result is 0.38 Pa m3/mol at room temperature, indicating low volatility of isophorone from surface waters.

Key value for chemical safety assessment
