Applied Surfactants


Book Description

While currently available titles either focus on the basics or on very specific subtopics, this text meets the need for a comprehensive survey of surfactants and their properties, with a strong emphasis on applications and their correlation to the fundamentals. The author covers their classification, physical properties, phase behavior, adsorption, effects - such as wetting, spreading and adhesion - as well as industrial applications in personal care and cosmetics, pharmaceuticals, agrochemicals and food products. Professor Tadros is a well-known expert on the topic of surfactants, with much experience in colloid science. Here, he uses his industrial experience to close the gap between fundamentals of surfactants and their relevance and applications in practice.

Microbial Surfactants


Book Description

Biosurfactants are surface-active biomolecules produced by a wide variety of microorganisms. They can be produced from renewable sources, and possess high surface activity, high specificity, low toxicity, tolerance to pH, temperature and ionic strength, biodegradability, excellent emulsifying and demulsifying ability and antimicrobial activity. Biosurfactants have found applications in several industries including organic chemicals, petrochemicals, mining, metallurgy (mainly bioleaching), agrochemicals, fertilizers, foods, beverages, cosmetics, pharmaceuticals and many others. The main aim of this volume is to highlight concepts, classifications, production and applications of microbial surfactants in food and agriculture. The book provides a comprehensive coverage of fermentation, recovery, genomics and metagenomics of biosurfactant production. It is presented in an easy-to-understand manner, and includes protocols, figures, and recent data on the industrial demand market and economics, and the production of biosurfactants from novel substrates are particularly worthwhile additions. The volume will be useful for students, researchers, teachers, and entrepreneurs in the area of microbial biosurfactants and their applications in food and agriculture.




Industrial Applications of Surfactants IV


Book Description

Environmental considerations are increasingly shaping the development of many industries. This is an overview of surfactants and the environment. It goes on to look at new surfactants derived from renewable, "natural" resources such as sucrose, seaweed and starch. Other chapters review a decade of change in the surfactant industry and assess future market trends. Some of the developments in surfactant technology are presented, including "gemini" twin-chained surfactants, sulfobetaines, alkyl phosphates and the use of alkyl alkoxylates and alkyl glucosides in highly alkaline solutions. The volume takes a practical approach throughout.







Surface Chemistry of Surfactants and Polymers


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.




Chemistry and Technology of Surfactants


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.




An Introduction to 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.




Natural Surfactants


Book Description

This book focuses on the use of natural surfactants in enhanced oil recovery, providing an overview of surfactants, their types, and different physical–chemical properties used to analyse the efficiency of surfactants. Natural surfactants discuss the history of the surfactants, their classification, and the use of surfactants in petroleum industry. Special attention has been paid to natural surfactants and their advantages over synthetic surfactants, including analysing their properties such as emulsification, interfacial tension, and wettability and how these can be used in EOR. This book offers an overview for researchers and graduate students in the fields of petroleum and chemical engineering, as well as oil and gas industry professionals.




Surfactants in Tribology


Book Description

The manufacture and use of almost every consumer and industrial product rely on application of advanced knowledge in surface science and tribology. These two disciplines are of critical importance in major economic sectors, such as mining, agriculture, manufacturing (including metals, plastics, wood, computers, MEMS, NEMS, appliances), construction, transportation, and medical instruments, transplants, and diagnostic devices. An up-to-date reference with contributions by experts in surface science and tribology, Surfactants in Tribology, Volume 3 discusses some of the underlying tribological and surface science issues relevant to many situations in diverse industries. The tradition of presenting new developments and research that began with the first volume in this groundbreaking series continues in the third volume. Comprising 19 chapters on various aspects of surfactants in tribology—including subjects not covered in previous volumes—this book is presented in four parts: Nanotribology and Polymeric Systems, Biobased and Environmentally Friendly Lubricants and Additives, Tribological Properties of Aqueous and Nonaqueous Systems, and Advanced Tribological Concepts. Topics include tribological properties of nanoparticles, biopolymer friction, environmentally friendly surface-active agents, biolubricants, aqueous mixed surfactant systems, and surfactants in motor oil, drilling fluids, and in electrowetting for MEMS and NEMS. The information in this volume provides a cutting-edge reference connecting the fields of surfactants and tribology as a way forward to novel, enhanced methods of controlling lubrication, friction, and wear. Written by a global team of established authorities, this book reflects the latest developments, highlighting the relevance of surfactants in tribological phenomena in a broad range of industries. It provides a valuable resource for readers working in or entering the fields of tribology and surface science.
