Additional information

In a study on the determination of the vapour pressure of the substance, conducted according to the OECD TG 104, static method, it was found that the value for the vapour pressure of the substance was below the limit of quantification (< 20 Pa).

The substance is a complex mixture and assessed as UVCB substance. In order to present a more specified value of the vapour pressure for the substance, calculations on vapour pressure were performed for representative constituents of the substance using the Estimation Program Interface EPI-Suite version 4.1.

Calculations were carried out for 5 representative constituents of the substance. The calculated vapour pressure of each constituent is regarded as partial pressure and is proportionately calculated based on the results of the examination on the material balance. Adding up the proportionated partial pressures, a calculated total pressure of 2.19E-08 Pa at 25 °C for the substance is obtained. The predicted value can be considered reliable yielding a useful result for further assessment.
