Emulsions and Emulsion Stability, Second Edition provides comprehensive coverage of both theoretical and practical aspects of emulsions. The book presents fundamental concepts and processes in emulsified systems, such as flocculation, coalescence, stability, precipitation, deposition, and the evolution of droplet size distribution.The book explains how to predict emulsion stability and determine droplet sizes in a variety of emulsion systems. It discusses spontaneous emulsification and the formation of “nanoemulsions” as well as droplet-droplet interactions in different electrical fields (electrocoalescence), and the formulation, composition, and preparation variables that contribute to the inversion in emulsion systems. Several chapters emphasize applications such as emulsification encountered in oil spills, asphalt, chemical flooding, acid crude oils, and large-scale industrial wastewater treatment. The survey of experimental characterization methods highlights the importance of thin liquid films in colloidal systems and assesses different NMR applications, ultrasound characterization, video microscopy, and other on-line instrumentation. The last chapter in the book deals with obtaining conductivity measurements as an alternative to online instrumentation. Completely revised and expanded, this second edition of Emulsions and Emulsion Stability offers a well-rounded collection of knowledge that is applicable to all academic and industrial scientists and researchers in the fields of surfactant and emulsion science.

The fundamental side of this book covers general aspects of stability, interfacial adsorption mechanisms, interfacial rheology, direct measurements of surface forces and the bulk rheological properties of emulsions, and self-diffusion properties as measured by NMR. The applications side covers the fields of food, crude oil and pharmaceutical emulsions. A central topic in the study of food emulsions is the role played by proteins at the water/oil interface, their conformations, and the mechanism by which they can be replaced at the interface (competitive adsorption). The mechanisms underlying the resolution of water are of crucial importance in the study of water-in-crude-oil emulsions. The book therefore discusses the characterization of the stabilizing asphaltene fraction, the physiochemical properties of destabilizing surfactants, and the interplay between asphaltenes and waxes at the W/O interface. The structures of pharmaceutical emulsions and creams are characterized, as well as nonionic vesicle drug administration systems. Finally, fluorocarbon emulsions acting as blood substitutes are also discussed.

A discussion of fundamental characteristics, theories and applications for liquid-liquid colloidal dispersions. It profiles experimental and traditional measurement techniques in a variety of emulsified systems, including rheology, nuclear magnetic resonance, dielectric spectroscopy, microcalorimetry, video enhanced microscopy, and conductivity.
