Description of key information

It was concluded that the test substance has a vapour pressure of 0.20 +/- 0.02 Pa.

Key value for chemical safety assessment

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

Additional information

The key study describes the determination of the vapour pressure of the test substance based on OECD and EU guidelines.

The vapour pressure was determined based on measurements made at 22.84, 28.68, 33.75, 28.11 and 22.67°C, using the Static Technique. The vapour pressure of the test substance at 25°C was calculated based on the measurements 70-191 and determined to be 0.20 +/- 0.02 Pa.


The measurements 1-92 were back extrapolated to the start of the measurements, to enable an estimation for the vapour pressure of the test substance, taken directly from the container. This vapour pressure was estimated to be 0.7 +/- 0.1 Pa at 25°C.
