Description of key information

Henry's law constant was calculated to be between 3.7E-09 and 1.2E-08 Pa.m3/mol at 25 °C based on experimental water solubility and estimated vapour pressures for the main components of the substance, indicating a low rate of volatilisation from surface water.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0
at the temperature of:
25 °C

Additional information

Henry's law constant was calculated to be between 3.7E-09 and 1.2E-08 Pa.m3/mol at 25 °C based on experimental water solubility and estimated vapour pressures for the main components of the substance [Harlan Laboratories (2010)]. This value indicates a low rate of volatilisation from surface water is expected.
