Book Description
Colloidal Surfactants: Some Physicochemical Properties focuses on the study of surface active agents. This book elaborates the importance of surface active agents in detergency, textile industry, and biological research. The four distinctive features of the substance—moderate maximum concentration of molecularly dispersed species; surface and interfacial depression in very dilute solution; micelle formation above a certain concentration; and solubilization of water-insoluble substances by micelles, are also described. Other topics include the effect of molecular type on the critical micelle concentration, critical micelle concentration, interaction of paraffin chain electrolytes with colloids, and monolayer studies of surface active agents. This publication is suitable for chemists and specialists researching on colloidal surfactants.

Book Description
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. The main objective of this graduate level textbook is to present an overview of the classification, physical properties, phase behavior, their effects and applications of surfactants, e.g. as emulsifiers, foam stabilizer, in nano- and microemulsions and as wetting agents.

Book Description
This book illustrates the importance and significance of the biosurfactants obtained from microorganisms, preferably from bacteria and yeast. It explains the superiority of biosurfactants (green molecule) over chemically synthesized surfactants for the sustainable future. The content of the present book addresses the quest for novel biosurfactants producing strains, high throughput screening methods, and production strategies. It finely describes the aptness of biosurfactants for industrial and environmental applications. It elaborately describes the technical background and cutting-edge advancement of the commercial aspect of biosurfactants. In the later part of the book, the role of green biosurfactants in food processing, control of food spoilage, incorporation in personal health care products, environmental and agricultural remediation are discussed. Finally, the book elucidates a comprehensive and representative description of toxicity assessment of the biosurfactants, which highlights the risk assessment of the incorporation of the microbial biosurfactants in food, healthcare, and pharmaceutical formulations.

Book Description
It is now twelve years since Solubilization by Surface-Active Agents appeared. Since the publication of that monograph the subject has expanded rapidly as the unique potential of surfactants has become known to a wider circle of scientists. In a recent review Menger (Accounts of Chemical Research, 12 (1979) 111) estimated that since 1970 there have been over 2800 publications on micelles and micellization alone. The topic of catalysis in micellar media was in an early stage of development in 1968 but the growth in this subject has given rise to an excellent textbook by Fendler and Fendler. We have felt for some time that a revision of Solubilization by Surface-Active Agents was overdue. The book has been out of print for some time. Owing to pressure of other work, Professor P. H. Elworthy and Dr C. B. Macfarlane were unable to undertake the work of revision but while working together on an undergraduate textbook the present authors decided to set to work, realizing both the impossibility of producing a comprehensive textbook and the need to alter the scope of the book. Micellar solubilization occurs over a relatively small surfactant concentration range; because of this and because the phenomenon is never observed in isolation, we have extended the text to include surface activity, emulsions and suspensions and, as our emphasis is on formulation of medicinal products, to the of the toxicology of surface-active agents.

Book Description
Surface Active Agents (surfactants) are vital components in biological systems, form key ingredients in consumer products and play an important role in many industrial processes. For example, cell membranes owe their structure to the aggregation of surfactants known as lipids which form a major component of the membrane. Other natural surfactants occur in the digestive system, in the lungs, and even in such substances as crude oil. Man-made surfactants are used in a wide range of domestic and industrial products and processes. In addition to detergents and personal care products, surfactants have found uses in almost every branch of the chemical industry as well as in several other industries. These include dyestuffs, fibres, mineral process ing, oil field chemicals, paints, pesticides, pharmaceuticals and plastics. Surfactants are versatile materials which are manufactured in a huge variety of forms to suit all of these applications. As a result of their importance, the technical literature on all aspects of surfactant behaviour is now very extensive. Surprisingly, however, the treatment in textbooks has been somewhat fragmented, often in the form of conference proceedings or edited, multi-authored works, both lacking in continuity.

Book Description
This book gives the reader an introduction to the field of surfactants in solution as well as polymers in solution. Starting with an introduction to surfactants the book then discusses their environmental and health aspects. Chapter 3 looks at fundamental forces in surface and colloid chemistry. Chapter 4 covers self-assembly and 5 phase diagrams. Chapter 6 reviews advanced self-assembly while chapter 7 looks at complex behaviour. Chapters 8 to 10 cover polymer adsorption at solid surfaces, polymers in solution and surface active polymers, respectively. Chapters 11 and 12 discuss adsorption and surface and interfacial tension, while Chapters 13- 16 deal with mixed surfactant systems. Chapter 17, 18 and 19 address microemulsions, colloidal stability and the rheology of polymer and surfactant solutions. Wetting and wetting agents, hydrophobization and hydrophobizing agents, solid dispersions, surfactant assemblies, foaming, emulsions and emulsifiers and microemulsions for soil and oil removal complete the coverage in chapters 20-25.

Book Description
Surface active agents are used as process aids in the production of polymers--as additives to impart or modify polymer properties--and in the formulation and further processing of polymeric systems for a variety of applications. In all these uses, the surfactants are used as 'effect chemicals,' to impart specific performance characteristics or properties to the base polymer or to enhance it performance when formulated for a specific end use. This volume focuses on those surfactant areas incorporating the greatest number of supplier and user companies. Authors have been selected from leading industrial and academic laboratories around the world. It provides an introduction to the underlying chemistry and technology in these industrial areas, and at the same time, highlights important recent developments. Surfactants in Polymers, Coatings, Inks and Adhesives is a book for surfactant researchers and for manufacturers and users of surfactants. In particular, surfactant chemists, analytical chemists, environmental chemists, users of surfactant formulations in the fields of specialty chemicals, polymers, and detergents, and health and safety personnel.

Book Description
Surfactants are used throughout industry as components in a hugerange of formulated products or as effect chemicals in theproduction or processing of other materials. A detailedunderstanding of the basis of their activity is required by allthose who use surfactants, yet the new graduate or postgraduatechemist or chemical engineer will generally have little or noexperience of how and why surfactants work. Chemistry & Technology of Surfactants is aimed at newgraduate or postgraduate level chemists and chemical engineers atthe beginning their industrial careers and those in later life whobecome involved with surfactants for the first time. The book is astraightforward and practical survey of the chemistry ofsurfactants and their uses, providing a basic introduction tosurfactant theory, information on the various types of surfactantand some application details. This will allow readers to build ontotheir scientific education the concepts and principles on which thesuccessful use of surfactants, across a wide range of industries,is based.
