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.

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.

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.

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.

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.

The microbial world has given us many surprises including microbes that grow under extremely harsh conditions (122C at 40 MPa), novel metabolisms such as the uranium and perchlorate reduction, and novel chemicals that can be used to control diseases. We continually face new and difficult problems such as the need to transition to more carbon-neutral energy sources and to find eco-friendly chemicals and to find new drugs to treat disease. Will it be possible to tap into the seemingly limitless potential of microbial activity to solve our current and future problems?The answer to this question is probably yes. We are already looking to the microbial world to provide new energy sources, green chemicals to replace those made from petroleum, and new drugs to fight disease. To help us along these paths, we are deciphering how microorganisms interact with each other. We know that microbial populations interact and communicate with each other. The language that microbes use is chemical where small molecules are exchanged among different microbial cells. Sometimes, these chemicals suppress activities of competitors and could be used as antibiotics or may have other therapeutic uses. Other times, the chemicals stimulate complex responses in microbial populations such as fruiting body or biofilm formation. By understanding the conversation that microbes are having among themselves, e. g.

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.

An excellent, concise, and interdisciplinary overview of different classes of emerging pollutants arising, for example, from pharmaceuticals, pesticides, personal care products, and industrial chemicals and their impact on water, soil, and air. Following an introduction to chemical pollutants, with special attention focused on organic compounds and their properties, the book goes on to describe major emerging pollutants grouped according to their applications in different sectors of industrial or economic activity. For each type of compound, the chemical structure, main properties, and source are presented, along with their fate in the environment as pollutants, the latest analytical methods for detection, possible health or ecology consequences, as well as current regulatory laws. New developments, such as nanotechnology as a pollution source, are also included. The book closes with a chapter devoted to conclusions and future perspectives.
