Concentrated emulsions or high internal phase emulsions (HIPE) are systems in which the volume fraction of the dispersed phase is larger than about 0.74, which is the close-packing volume fraction of monodispersed hard spheres. The dispersed soft entities of a concentrated emulsion are no longer spherical. They deform into polyhedra separated by thin films of continuous phase. The structure is thus analogous to a conventional gas-liquid foam with low liquid content. The structure, properties, stability, and applications of highly concentrated emulsions were recently reviewed by Cameron and... 

Figure 1 Pair-wise-interaction energy between spherical particles i and j in an electrostatically-stabilized dispersion. The potential Ujj(r) is plotted agairtst rja, where r is the centre-to-centre separation and a is the particle radius. Three regions of the potential are identified primary minimum (A), primary maximum (B), (height u J, and secondary minimum (C). The dotted line represents an effective hard-sphere potential...
