Key value for chemical safety assessment

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

Additional information

The vapour pressure of the substance was determined by a vapour pressure method following EU method A.4 and OECD 104 guidelines. Vapour pressure measurements were collected between 55 - 65 degrees C. A calibration plot of logPa vs. reciprocal temperature, 1/K permitted extrapolation of vapour pressure at 25 and 70 degrees C.


Results of the analysis showed the vapour pressures of the substance is 0.011 Pa at 25 deg. C and 0.71Pa at 70 deg. C which is the highest temperature at which the substance is used.


No apparent change in the appearance of the substance was noted over the course of the test.
