Additional information

The vapour pressure of the substance was determined by QSAR calculations with SPARC v4.6, performed for single components. The results of 9.79E-44 - 8.05E-22 Pa at 20 °C for the main constituents reported in section 1.2 indicate that the substance is non-volatile and the overall vapour pressure is estimated as < 0.0001 Pa.
