Emulsion molecular description

In the past, emulsion properties were seen from a physical point of view to involve forces and hydrody-namic motion in the interdrop thin film. Thanks to the physicochemical concepts developed for the enhanced oil-recovery processes, a newer physicochemical approach, based on a molecular description of the interaction between the interfacially adsorbed surfactant and the oil and water phases, is now available and will be emphasized here. 

It is most impressive to find how theoretical knowledge has led to some fascinating developments in the technology. The purpose of this handbook is also to further this development. The molecular description of liquid surfaces has been obtained from surface tension and adsorption studies. The emulsion (microemulsion) formation and stability are described by the interfacial film structures. The surfaces of solids are characterized by contact angle and adsorption studies. The ultimate in interfaces is an extensive description of chemical physics of colloid systems and interfaces. Contact angle and adhesion is described at a very fundamental level. The thermodynamics of... 

Therefore, in the detailed descriptions of model emulsions given below, nearly all of them (especially where the surfactant proteins are considered at the molecular level) concern themselves with the milk proteins. 

It is the purpose of this chapter to sketch a statistical approach of wave-number-dependent fluctuations within the background of the STL, which goes beyond the correlation length concept, by incorporating in particular high order moments of the pair direct correlation function, at the level of description of molecular liquids. This approach permits one to unify the Teubner-Strey (TS) approach of microemulsions (Teubner and Strey 1987) to the usual Ornstein-Zernike approach of molecular emulsions in general.
