20 °C

Additional information

In a key study, the isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure based on OECD 104 and EC A.4.

The vapour pressure of the test item extrapolated to 20 °C was 0.000011 mmHg. The evaporation rates of the test item were obtained with temperatures above the melting temperature of the test item. Therefore, the vapour pressure reported might be overestimated.
