The vapour pressure of the UVCB Polyglycerine sample was measured, with significant contribution from water present. The vapor pressure of the subsance exclusive of water is expected to be equal to or lower than that of the primary component (glycerine) which is also expected to be most volatile component.
The vapor pressure of the UVCB Polyglycerine sample, containing 4.98% wt
water was 490 and 658 Pa at 20 and 25 °C, respectively. The vapor
pressure of the subsance exclusive of water is expected to be equal to
or lower than that of the primary component (glycerine) which is also
expected to be most volatile component. The vapor pressure of glycerine
has been measured in the Key Study at 50, 100, and 150 °C; giving values
of 0.33, 26.0, and 573 Pa respectively. The extrapolated VP at 25 °C is
0.0223 Pa, using the prediction equation and associated
critically-reviewed and accepted VP vs. Temp. data of the DIPPR Database
