Description of key information

The HLC for C16 TMAC was calculated to be 2.88 x 10-10 atm-m3/mole (i.e., equivalent to 0.0000292 Pa-m3/mole)

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0
at the temperature of:
25 °C

Additional information

The Henry’s law constant (HLC) of C16 TMAC was estimated using the HENRYWIN v3.20 model. The method uses valid Bond contribution values, which are determined for 59 chemical bonds by a least-square analysis of HLCs for 345 organic compounds. The HLC was finally calculated on a weighted-average basis using the mole fractions of the individual components and was found to be 2.88 x 10-10 atm-m3/mole (i.e., equivalent to 0.0000292 Pa-m3/mole) (US EPA, 2012b), indicating that the substance is non-volatile.
