Henry's Law constant
Administrative data
Link to relevant study record(s)
Description of key information
The Henry`s law constant was calculated using experimental results on water solubility and vapour pressure at 20°C.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0
- at the temperature of:
- 20 °C
Additional information
Based on the vapour pressure of the substance (1.4·10 -6 hPa (20°C)), Neo Heliopan® AP can safely be considered as non-volatile. In addition, a calculation of Henry`s law constant at 4.72·10-5 Pa m³/mol on the basis of the experimental determination of water solubility and vapour pressure, indicates that the substance does not volatilize from water or wet surfaces.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
