The proposed 1996 paper relates the surface tension of mixtures to bulk-phase concentrations and properties (i.e. densities). Surface tension of pure organic fluids σ:
The two ρ are densities: liquid and vapour.
They introduced parachor (
P), a new expression, derived from statistical mechanics (from Macleod equation) which represents the experimental surface tension of 94 different organic compounds within 1.05 AAD% (average absolute deviations).
(Kumar 2005) It expresses the surface tension of a liquid in equilibrium with its own vapour. Historical reference for parachor cited here: Macleod, Sugden, Quayle, Escobedo.
Surface Tension Prediction for Liquid Mixtures

Surface tension of pure organic fluids was proposed previously also by them in 1996. The same theory is extended to the case of mixtures of organic liquids.
