Description of key information

The vapour pressure of the test substance at 20°C (293K) was < 1.33 x 10-8 Pa, or  < 1.00 x 10-10 mm Hg.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C

Additional information

The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of DOWFAX 2A1 - DRY. The vapour pressure of the test substance at 20 °C (293K) was < 1.33 x 10 -8 Pa, and at or below the applicable lower limit of the test method. Further definition of vapor pressure below this value is not informative for the chemical safety assessment.
