Book Description
Surface Active Chemicals resents a number of applications of surface activity. This book provides a discussion of bulk solution phase properties, which is important for proper understanding of surface phenomena. Organized into seven chapters, this book begins with an overview of the works of cohesion of some organic liquids and their woks of adhesion to water. This text then describes the properties of ordinary soaps, which consist of blends of alkali–metal or organic base salts of fatty acids of from eight to eighteen carbon atoms. Other chapters consider the characteristic of soapy lather by the addition of excess fatty acid to soap, which raises its proportion in the surface layer still further and tends to make the lather even creamier. This book discusses as well the processes for the extraction of bone glue. The final chapter deals with the statistics of production and sales for soaps and detergents. This book is a valuable resource for chemists and senior students.

Book Description
Most modern surfactants are readily biodegradable and exhibit low toxicity in the aquatic environment, the two criteria for green surfactants. However the majority are synthesised from petroleum, so over the past decade the detergent industry has turned its attention to developing greener routes to create these surfactants via renewable building blocks. Surfactants from Renewable Resources presents the latest research and commercial applications in the emerging field of sustainable surfactant chemistry, with emphasis on production technology, surface chemical properties, biodegradability, ecotoxicity, market trends, economic viability and life-cycle analysis. Reviewing traditional sources for renewable surfactants as well as recent advances, this text focuses on techniques with potential for large scale application. Topics covered include: Renewable hydrophobes from natural fatty acids and forest industry by-products Renewable hydrophiles from carbohydrates, amino acids and lactic acid New ways of making renewable building blocks; ethylene from renewable resources and complex mixtures from waste biomass Biosurfactants Surface active polymers This book is a valuable resource for industrial researchers in companies that produce and use surfactants, as well as academic researchers in surface and polymer chemistry, sustainable chemistry and chemical engineering.

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.

Book Description
The worldwide consumption of surfactants now exceeds several million tonnes per annum. Six ofthe major types represent approximately 80% ofthe volume consumed, whereas the remaining 20% is made up of approximately 40 different chemical types. Commercially produced surface active agents are not pure chemicals, and within each chemical type there can be tremendous variation. Technical staff who are not familiar with surfactants are frequently bewildered by the enormous variety of different products on the market and the vast body of literature which exists on the composition and properties of surfactants. The selection of the best surfactant for any given use therefore becomes a major problem. This volume arose from the clear need to have available a simple reference book summarising the different types of surfactants on the market and their properties. The concept and structure of the book evolved from early attempts to define chemical structure/property relationships of all the different types of surfactants commercially available, into a simple handbook providing essential background information for the surfactant user. It is realised that most users will be developing their own data bank of structure/end use property relationships and they will therefore be the experts on end use.

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
The awareness and development of 'biodegradable' surfactants pre-dates current pressures by the environmental movement by nearly three decades, wherein a responsible industry mutually agreed to replace 'hard', non-biodegradable com ponents of household detergents by 'soft', biodegradable alternatives, without course to legislation. The only requirement at that time was for surfactants used in detergents to exhibit a 'primary biodegradability' in excess of 80%; this referring to the disap pearance or removal from solution of the intact surface active material as de tected by specified analytical techniques. This proved useful, as observed environmental impacts of surfactants, e.g. visible foam on rivers, are associated with the intact molecule. Test methods for 'primary biodegradability' were eventually enshrined in EU legislation for nonionic surfactants (Directive 821242/EEC, amended 73/404IEEC) and for anionic surfactants (Directive 8212431EEC, amended 73/405IEEC). No approved test methods and resultant legislation have been developed for cationic and amphoteric surfactants to date. The environmental classification of chemical substances, which of course includes surfactants, and associated risk assessment utilises a second criterion 'ready biodegradability'. This may be assessed by a number of methods which monitor oxygen uptake (BOD), carbon dioxide production or removal of dis solved organic carbon (DOC). Some surfactants which comply with the above Detergents Directive are borderline when it comes to 'ready biodegradability'.
