Surfactants And Detergents

Surfactants by virtue of their structure form self-assembled organized structures that exhibit fascinating properties useful for a wide range of applications. This book is a compilation of chapters from leading experts highlighting the use of specific surfactants and their functional properties in new and emerging areas of science and technology. The first two chapters of this book discuss the various applications of surfactants, including their use in cosmetics, oil recovery from rocks and mineral processing. Subsequent chapters cover advanced topics like new-generation polymer-based nanoparticles with microbial activity and complex phase systems formed as a result of charge-induced interactions between surfactants, polymers and proteins with potential applications in medical devices. In addition, this book reports for the first time on bio-surfactants extracted from micro-organisms present in the clouds. This report is not the only one of its kind, but it opens up a totally new area of research in terms of an unexplored source of bio-surfactants. It also paves the way for understanding their role in controlling our atmosphere and climate.

An Examination of Detergent Applications The fifth volume in a six volume project penned by detergent industry experts, this segment deals with the various applications of detergent formulations - surfactants, builders, sequestering/chelating agents - as well as other components. These applications are discussed with respect to the scope

Surfactants are ubiquitous and have applications in diverse areas, including food, cosmetics, detergents, lubricants, enhanced oil recovery (EOR), and targeted drug delivery systems. Their wide diversity of applications owes to their unique structure, namely, a hydrophilic and a hydrophobic group present in the same molecule. Although most surfactants used industrially are synthetic, there is a growing need for natural surfactants, as the latter is obtainable from renewable sources and are less toxic and highly biodegradable in contrast to their synthetic counterparts. This book is a compilation of interesting articles by various experts that cover various applications of both synthetic and natural surfactants.

"Two common terms used to describe surface-active materials are amphiphiles and surfactants. The term amphiphile is derived from Greek-amphis meaning "both" and philia meaning "love or friendship." An amphiphilic chemical is a chemical whose molecular structure has one or more hydrophilic groups and one or more hydrophobic groups. Another Greek-derived synonymic term used to describe amphiphilic chemicals is amphipathic (amphis meaning "both" and pátheia meaning "feeling"). Because all surfactants possess hydrophilic and hydrophobic groups, they are termed as amphiphilic or amphipathic compounds. The term surfactant, a contraction of surface-active agent, implies the material is active at surfaces. Surfactants have the tendency to adsorb at surfaces as well as interfaces. The difference between surfaces and interfaces is that surfaces involve a gas, usually air, as one of the phases, and the interfaces are boundaries between two immiscible phases. Five interfaces are possible from three common states of matter (solid, liquid, and gas)"--

The scope and spectrum of methods and techniques applied in detergent analysis have changed significantly during the last decade. Handbook of Detergents, Part C: Analysis demonstrates state-of-the-art strategies, methods, and techniques for the analytical deformulation of modern detergents. It offers a comprehensive view of all aspects of de

In to days market, custom formulated surfactants are offered for a wide range of applications. The need for surfactants in detergents, cleaning agents, cosmetics & toiletries is second only to an expanding demand in industrial applications. But even within the non-industrial areas the demands have undergone significant changes in recent years. For example, washing and cleaning temperatures have substantially decreased with increased energy conservation attitudes, and more stringent regulatory requirements in the area of ecology and toxicology are leading to new product profiles. New manufacturing technologies and an increased utilization of natural raw materials also factor into this continuing evolution. These changes and trends have been described in numerous publications. However, a summary and survey of these developments is currently missing. The book presented here "Surfactants in Consumer Products" is intended to close this gap. The editor and authors dedicate this work to Dr. Dr. h.c. Konrad Henkel on the occasion of his 70th birthday. Dr. Henkel, himself a scientist and industrialist, contributed signifi cantly to developments in the surfactant field. In the nineteen-fifties, he initiated the change from soap based detergents to synthetic detergents within Henkel. At the same time, dishwashing detergents utilizing various synthetic surfactants were also developed, and became the basis for modem manual and mechanical dishwashing.

Biobased Surfactants: Synthesis, Properties, and Applications, Second Edition, covers biosurfactant synthesis and applications and demonstrates how to reduce manufacturing and purification costs, impurities, and by-products. Fully updated, this book covers surfactants in biomedical applications, detergents, personal care, food, pharmaceuticals, cosmetics, and nanotechnology. It reflects on the latest developments in biobased surfactant science and provides case scenarios to guide readers in efficient and effective biobased surfactant application, along with strategies for research into new applications. This book is written from a biorefinery-based perspective by an international team of experts and acts as a key text for researchers and practitioners involved in the synthesis, utilization, and development of biobased surfactants. Describes new and emerging biobased surfactants and their synthesis and development Showcases an interdisciplinary approach to the topic, featuring applications to chemistry, biotechnology, biomedicine, and other areas Presents the entire lifecycle of biobased surfactants in detail
