Endpoint:
Henry's law constant
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
supporting study
Rationale for reliability incl. deficiencies:
accepted calculation method
Principles of method if other than guideline:
According to the calculation from the R16 guidance: HLC=Vapour Pressure (Pa)*MW (g/Mol) / Water solubility (mg/L)
Key result
H:
0.002 Pa m³/mol
Remarks on result:
other: Calculated
Conclusions:
HLC= 0.0024 Pa*m3/Mol
Executive summary:

Henry's Law Constant of TMAO was calculated from the vapour presure, the molecular weight and the water solubility values, as stated in the R16 ECHA guidance and was determined to be 0.0024 Pa.m3/Mol.
