Additional information

The vapour pressure of the substance isononanoic acid, C16-18 alkyl esters (CAS No. 111937-03-2) was determined by Grain-Watson estimation according to OECD Guideline 104 due to worst case considerations. The experimental value (5.5E-8 Pa at 20 °C) determined by differential scanning calometry is fits with the values (4.94E-7 - 4.25E-8 Pa at 20 °C) determined for the single components by QSAR calculation with SPARC (v4.5).
