Description of key information

The AHTN vapour pressure has been used for read across in the safety assessment of HMT. A vapour pressure of 0.07 Pa has been determined by the gas saturation method. The calculated value by EPIWIN was 0.4 Pa.

Key value for chemical safety assessment

Vapour pressure:
0.4 Pa
at the temperature of:
25 °C

Additional information

MPBPWIN v. 1.43 in EPIWIN has been used to calculate the vapour pressure. It is 0.4 Pa, while for the structural related AHTN compound (1 -(5,6,7,8 -tetrahydro-3,5,5,6,8,8 -hexamethyl-2 -naphthyl)ethan-1 -one / CAS: 1506 -02 -1), the vapour pressure measured by the gas saturation method was 0.07 Pa. Both these pressures are very small and hence the calculated value has been taken forward for reporting.
