Description of key information
The Henry's law constant was estimated to be 4.8 Pa m³/mol according to "Guidance on information requirements and chemical safety assessment Chapter R.16: Environmental Exposure Estimation".
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 4.8
- at the temperature of:
- 285 K
Additional information
The Henry's law constant of the L-Menthol was calculated in accordance with "Guidance on information requirements and chemical safety assessment Chapter R.16: Environmental Exposure Estimation". In the guidance, Henry's law constant = VP × MOLW / SOL.
VP was derived from section 4.6 of this dossier ----19 Pa @ 25 C degrees (298 K) ---- 11 Pa at 285 K;
SOL was derived from section 4.8 of this dossier ---397 mg/l @ 20 C degrees (293 K) ---- 356 mg/l at 285 K.
MOLW ---- 156.27 g/mol
Thus, the Henry's law of L-Menthol at 285 K is 4.8 Pa m3 / mol.
