Book Description
In the tradition of the popular first edition, Analysis of Surfactants, Second Edition offers a comprehensive and practical account of analysis methods for determining and understanding commercially important surfactants-individually and in compounds. Combining a complete review of the literature with a variety of evaluation procedures and the specifications for commercial products, this useful reference explores the key stages and latest developments for surfactant applications. This edition has been thoroughly expanded and features new sections on capillary electrophoresis, ether carboxylates, and ester quats. It is also more globally accessible with foreign language citations and SI units. Containing over 2400 references, drawings, tables, and equations, Analysis of Surfactants, Second Edition is an recommended reference for physical, surface, colloid, and oil chemists; analytical, research, and quality assurance chemists working in the soap and detergent, pharmaceuticals, and cosmetic industries; regulatory and food scientists; and upper-level undergraduate and graduate students in these disciplines.

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
Surfactants in Biopharmaceutical Development addresses the progress, challenges and opportunities for surfactant research specific to pharmaceutical development, providing a broad range of important surfactant-related topics as they relate directly to the biopharmaceutical process. Chapters address fundamental topics, like mechanisms of protein stabilization by surfactants, the latest, state-of-the-art technology and methods to illustrate the practical application to biopharmaceutical development, forward-looking chapters on control strategies and novel surfactants, with a special focus on current regulatory aspects of paramount importance for biopharmaceutical companies and regulators. It has been widely recognized that surfactants provide protection to therapeutic proteins against interfacial stresses. Despite the fact that the very mechanism of protein stabilization by surfactants has not been completely understood, surfactants are universally regarded as critical functional excipients by the industry and by regulators. Describes the current state of research on surfactants in the context of biopharmaceutical development, drawing upon contributions from international experts across industry, academia, and regulators Addresses the opportunities and challenges associated with surfactants in biologic drug development Provides a defining resource for practitioners in the biopharmaceutical industry, regulators and academics by summarizing the latest knowledge of surfactants in biopharmaceutical development in one comprehensive volume

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'.

Book Description
The surfactants are among the materials that have a significant importance in everyday life of human. The rapid growth in science and technology has opened new horizons in a very wide range, in which the surfactants play a major and vital role. Hence, the increasing number of applications as well as arising environmental issues has made this relatively old topic still a hot research theme. In the first section of this book, some of the applications of surfactants in various fields such as biology and petroleum industry, as well as their environmental effects, are described. In Section 2 some experimental techniques used for characterization of the surfactants have been discussed.
