Description of key information
The Henry's Law Constant of the substance was calculated to be 3.37E-2 and 2.78E-3 Pa m³/mol following the bond estimation method and the group estimation method, respectively (HenryWin, US EPA, 2011).
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0.034
- at the temperature of:
- 25 °C
Additional information
The Henry's Law Constant is calculated following both the bond estimation and the group estimation method to be very low indicating that the substance will predominantly be in the water phase. The highest calculated value was taken as the key value for chemical safety assessment as a worst case estimate.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
