Like the preceding volumes, Volume 3 of Annual Surfactants Review focuses on the diversity of surfactants, both in terms of chemical structure and physico-chemical/surface active properties. Although they may be predictable for simple molecules, for most commercial surfactants, this is not easy. It remains important, however, to understand the interactions within a multi-component mixture in order to select the most appropriate product for an application. Chapter One of this volume considers surfactant application in the context of structure-performance relationships. It forms a unique guide to the influence of chemical structure on end-use performance that illustrates how some of the newer classes of surfactants overcome deficiencies of previously used products. Chapter Two explores surfactant-polymer interactions-an area of significant current interest. The remaining chapters illustrate the diversity of surfactant applications and focus on some of the latest developments in application technology. Written by outstanding scientists in the field of surface chemistry, 'Surface Active Behaviour of Performance Surfactants' continues the tradition of Annual Surfactants Review by covering carefully selected topics that offer a snapshot of the many studies undertaken worldwide. It provides a valuable reference for chemists whose work involves the production, formulation, and application of surface active agents.
