- Conclusions:
- The predicted value for the vapour pressure of the substance is : 3.08 x 10-15 Pa at 20 °C, using MPBPWIN v1.43 included in EPI-Suite v 4.11, 2000 - 2012.
- Executive summary:
The substance is a substance of unknown or variable composition, complex reaction products or biological material (UVCB). A representative molecular structure was used for the prediction of the vapour pressure using the Estimation Program Interface (EPI) Suite version 4.11. These main components account for approximately 85.7 % of the test item and differ only in terms of lengths of their alkyl chains attached. The vapour pressure of the substance was estimated to be 3.08E-15 Pa (at 20 °C) using the MPBPWIN v1.43 model included in the EPI-Suite Programm. The value for the representative structure of the UVCB substance falls within the applicability domain described above and, therefore, the predicted value can be considered reliable.
