Rationale for reliability incl. deficiencies:
other: Calculation
Principles of method if other than guideline:
Henry's Law Constant equation: (vapour pressure*molecular weight)/(water solubility*1000)
GLP compliance:
no
H:
0.683 Pa m³/mol
Temp.:
20 °C

Conclusions:
The Henry's Law constant for polysulfide di-tert-nonyl is 0.683 Pa/m3-mol.
Executive summary:

This equation for calculating the Henry's Law Constant is indicated in the Guidance on information requirements and chemical safety assessment (IR & CSA) Chapter 16 "Environmental exposure estimate" (Equation R.16-10, ECHA 2010) and is therefore considered an appropriate technique.
