Description of key information

<<0.00016 Pa at 25°C (estimated)

Key value for chemical safety assessment

Additional information

The measurement was performed using gas saturation.

Based on the results of the vapour pressure model calculation the experiment was performed at 50°C, 60°C and 70°C. These temperatures were chosen because the evaporation of the test item was expected to be very low at lower temperatures

At none of the used temperatures any significant amount of test item could be detected, thus the vapour pressure was calculated using the least concentrated calibration solution. An extrapolation of the results was not performed. Still it can be deduced that the vapour pressure at 25°C is expected to be well below the calculated results.

Based on the experimental results the vapour pressure of test item at 25°C is expected to be << 0.00016 Pa at 25°C
