“Therefore, it is an essential and interdisciplinary guideline, and warmly recommended not only to those working in the field of dispersions/suspensions in pharmaceutical, cosmetic, food, paint, ceramic and agricultural industries but also to students, scientists and practitioners in other scientific fields (chemistry/food science & technology/food processing, production, etc).” (Advances in Food Science, 1 January 2013)
To successfully disperse a powder into a liquid and prevent aggregation of the particles, the properties and effects governing their combining need to be examined. This book explains the fundamentals required to enable the reader to produce suspensions that can be applied in a variety of industries. The 13 chapters will inform formulation chemists how best to prepare a suspension in a more rational manner, by applying the principles of colloid and interface science, while at the same time enabling the research scientist to discover new methods for preparing stable suspensions.
From the contents:
* General Introduction
* Fundamentals of Wetting and Spreading
* The Critical Surface Tension of Wetting and the Role of Surfactants in Powder Wetting
* Structure of the Solid-Liquid Interface and Electrostatic Stabilization
* Electrokinetic Phenomena and Zeta Potential
* General Classifi cation of Dispersing Agents and Adsorption of Surfactants at the Solid-Liquid Interface
* Adsorption and Conformation of Polymer Surfactants at the Solid-Liquid Interface
* Stabilization and Destabilization of Suspensions Using Polymeric Surfactants and the Theory of Steric Stabilization
* Properties of Concentrated Suspensions
* Sedimentation of Suspensions and Prevention of Formation of Dilatant Sediments
* Characterization of Suspensions and Assessment of Their Stability
* Rheological Techniques for Assessment of Stability of Suspensions
* Rheology of Concentrated Suspensions
This book is essential reading for those working in the pharmaceutical, cosmetic, food, paint, ceramic, and agricultural industries.

About the Author
Tharwat F. Tadros was appointed lecturer in Physical Chemistry at Alexandria University in 1962 and served in this position until 1966. Between 1966 and 1969, he spent his sabbatical leave at the Agricultural University of Wageningen and T.N.O. in Delft, The Netherlands. Thereafter, he joined I.C.I. and ZENECA until 1994, where he researched various fields of surfactants, emulsions, suspensions, microemulsions, wetting, spreading & adhesion, and rheology. During that period he was also appointed visiting professor at Imperial College London, Bristol University, and Reading University. In 1992, he was elected President of the International Association of Colloid and Interface Science. Since leaving ZENECA, Tharwat F. Tadros has worked as a consultant for various industries and has also taught several courses in his specialized field. He is the recipient of two medals from the Royal Society of Chemistry in the UK, and has more than 250 scientific papers to his name.
