Henry's Law constant
Administrative data
Link to relevant study record(s)
Description of key information
Due to the ionic nature of the substance, volatilization from the aqueous phase is not expected.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0.068
- at the temperature of:
- 25 °C
Additional information
Experimental data on Henry`s law constants are not available. The Henry constant is calculated using the QSAR tool EPISuite (US-EPA, 2000 -2008) to be 6.68E-007 atm-m³/mol (6.77E-002 Pa-m³/mol), which predict a low volatilisation. However, the calculated data may not be a realistic reflection of the constants, since surfactant properties are not taken into account by the model. Due to the ionic nature of the substance, volatilization from the aqueous phase is not expected (SIDS, 2007).
