The brief discussion as presented above highlights the richness and complexity underlying spontaneous emulsification, the understanding of which requires adequate blends of interfacial science, transport phenomena, phase evolution kinetics within the domain of non-equilibrium thermodynamics. It may be naïve to presume that a general understanding of spontaneous emulsification is imminently forthcoming, although certain semi-empirical approaches, such as those based on the calculation of HLB 1 (hydrophobic lipophilic balance) and/or the HLD (hydrophobic lipophilic difference) numbers for a combination of surfactant, oil, water provide useful insights into such mechanisms. Additionally, the sudden transformation of an oil/water to water/oil emulsions or vice versa, which are recognized to be parts of the overall emulsification hierarchy can be captured using the idea of cusp catastrope . However, this method, understandably, does not provide the much-needed mechanistic insights into the local processes as it does not claim to be anything more than a phenomenological model. We are motivated by the hypothesis that understanding the local processes, including those involving singular transformations of one phase to another, is important to develop a comprehensive understanding of the emulsification processes.
