Description of key information

The Henry's Law constant for polysulfides, di-tert-dodecyl is 1.177 Pa/m3-mol.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
1.177
at the temperature of:
20 °C

Additional information

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) and is therefore considered an appropriate technique. There are limitations design and reporting, but the calculated value is considered suitable for use for this endpoint.
