Colloids and Interfaces with Surfactants and Polymers is both an introduction to the field and a bridge to the more specialist texts that are available, and includes recent ideas that have been developed on the interactions between particles and the concentrated state.

By the nature of the subject, some areas are necessarily complex, but when this occurs this text includes a calculation strategy so that the reader can judge the depth required for the application under study. Many commercial systems are complex mixtures but in most cases the basic rules apply and surprises only occur when there is a quite specific interaction present.

Hence, using Colloids and Interfaces with Surfactants and Polymers, the reader will always have the fundamentals readily to hand. This book summarises such fundamentals in an accessible fashion and is relevant for undergraduate courses on chemistry, chemical engineering, physics, material science or pharmaceutics.
