When I understand it right interfacial tension is defined for a pair of two phases. When there is a third phase I think only an 'apparent interfacial tension' can be measured directly.

I wonder whether by sonication of let's say, a 1/1 paraffin oil (viscosity 250 mPa*s, density 0.87 g/cm³) o/w is favored also for emulsifiers like Span 20 (1 % m/m emulsion). May it be that...

I expect dispersibility is meant. One should avoid confusion of terms. Unfortunately it is often asked how to best 'dissolve' particles but 'disperse' is meant.
