Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The Henry's Law Constant has been calculated to be 4.76 Pa.m3/mol. Therefore, Methyl Salicylate is considered as moderately volatile from water at 25°C
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 4.76
- at the temperature of:
- 25 °C
Additional information
The Henry's Law constant of methyl salicylate has been calculated according to the equation R16-10 of the guidance on information requirements and chemical safety assessment - chapter R16: environmental exposure assessment (ECHA 2010).
The equation used is the following :
HENRY = ( VP x MOLW ) / SOL
With ( as vapour pressure and water solubility values have not been measured at the same temperature, these values have been extrapolated to the data at 25°C using EUSES calculation):
VP = 18.3 Pa at 25°C (data extrapolated from the measured value at 13 Pa at 20°C).
MOLW = 152.13 g/mol
SOL = 585 mg/L at 25°C (data extrapolated from the measured value of 625 mg/L at 30°C)
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.
