Our book provides anintroduction that covers nanodispersions. Most often used in the Pharmaceutical, Food and Cosmetics industry, liposomes are used to carry drugs, peptides, proteins, vitamins, and other actives to specific target destinations (organs).

Emulsions provides a general introduction, the industrial role of emulsifiers and addresses different problems such as creaming/sedimentation, flocculation, Ostwald ripening, coalescence and phase inversion. Thermodynamics, adsorption and interaction forces between emulsion droplets are thoroughly explained. Supplemented by many figures and tables, it helps to characterize and select the right emulsifier for various industrial applications.

Surfactants are surface active agents, molecules that have a significant role in emulsions, suspensions, and foams. They find widespread application in personal care, cosmetics, pharmaceuticals, agrochemicals and the food industry.Their classification, physical properties, phase behavior, their effects and applications are covered in this book.

The main objective of this volume is to demonstrate the importance of the fundamental aspects of interfacial phenomena in various industrial applications. The text provides the reader with the knowledge that is essential for the composition of the complex multi-phase systems used in the above mentioned areas of application. It should enable the physical and formulation chemist as well as the chemical engineer in designing the formulation on the basis of a rational approach. It will also enable the formulation scientist to better understanding the factors responsible for producing a stable...

Suspension Concentrates is a survey into the theory of the formulation and stabilization of suspensions, elaborating on the breaking of aggregates and agglomerates and the role of dispersing agents on flocculation and electrostatic and steric stabilization. Practical analysis by rheology is discussed. Suspension Concentrates is ideal for research scientists and Ph.D. students investigating chemistry, chemical engineering and colloidal science.
