Surfactants In Solution

Contains selected invited papers presented at the 10th International Symposium on Surfactants in Solution held in Caracas, Venezuela. The volume covers phase behaviour of monolayers, contact angle hysteresis, micellar relaxation, micellar catalyzed reactions, polymerization in microemulsions, polymer-surfactant complexation, asphaltenes, and more.

This volume chronicles the proceedings of the 8th International Symposium on Surfactants in Solution (SIS) held in Gainesville, FL, June 10-15, 1990. This series of symposia have been smoothly running since 1976, but the appellation "Surfactants in Solution" was used for the first time in 1982 in Lund. Since then our logo "SIS" has become very familiar to everyone involved in surfactants. In Lund the meeting was billed as the Fourth International Symposium on Surfactants in Solution. Earlier three events were held under different rubrics, but proceedings of all these symposia, except the 7th SIS held in Ottawa in 1988, have been properly documented. As a matter of fact so far 10 volumes have appeared under the title "Surfactants in Solution". 1,2,3 The program for the 9th SIS was very comprehensive and many ramifications of surfactants were covered, and it was a veritable international event. It contained a total of 384 papers by 869 authors from practically every corner of our planet. Just the sheer number of papers is a testimonial to the high tempo of research and tremendous interest in this wonderful class of materials. As in the past, there were plenary lectures (5), invited talks (37), oral presentations (195) and poster presentations (147). The plenary lectures were given by Prof. J. Th. G. Overbeek, Prof. C. A. Bunton, Prof. H. Ti Tien and Dr. J. Swalen. The lecture by Prof. Overbeek, the doyen of surface and colloid science, was a real treat.

This and its companion Volumes 2 and 3 document the proceed ings of the 4th International Symposium on Surfactants in Solution held in Lund, Sweden, June 27-July 2, 1982. This biennial event was christened as the 4th Symposium as this was a continuation of ear li er conferences dealing with surfactants held in 1976 (Albany) under the title "Micellization, Solubilization, and Microemulsions"; in 1978 (Knoxville) under the title "Solution Chemistry of Surfac tants"; and in 1980 (Potsdam) where it was dubbed as "Solution Be bavior of Surfactants: Theoretical and Applied Aspects:' The Pl02 3 ceedings of all these symposia have been properly chronicled. ', The Lund Symposium was bi lIed as "Surfactants in Solution" as both the aggregation and adsorption aspects of surfactants were covered, and furthermore we were interested in a general title which could be used for future conferences in this series. As these biennial events bave become a weIl recognized forum for bringing together researchers with varied interests in the arena of surfactants, so it is amply vindicated to continue these, and the next meeting is planned for July 9-13, 1984 in Bordeaux, France under the cochair manship of K.L. Mittal and P. Bothorel. The venue for 1986 is still open, although India, inter alia, is a good possibility. Apropos, we would be delighted to entertain suggestions regarding where and when these biennial symposia should be held in the future and you may direct your response to Kk~.

Offering the latest research and developments in the understanding of surfactant behavior in solutions, this reference investigates the role and dynamics of surfactants and their solution properties in the formulation of paints, printing inks, paper coatings, pharmaceuticals, personal care products, cosmetics, liquid detergents, and lubricants. Exploring the science behind techniques from oil recovery to drug delivery, the book covers surfactant stabilized particles; solid particles at liquid interfaces; nanocapsules; aggregation behavior of surfactants; micellar catalysis; vesicles and liposomes; the clouding phenomena; viscoelasticity of micellar solutions; and more.

Many industrial formulations such as detergents, paints, foodstuff and cosmetics contain both surfactants and polymers and their interaction govern many of the properties. This book is unique in that it discusses the solution chemistry of both surfactants and polymers and also the interactions between the two. The book, which is based on successful courses given by the authors since 1992, is a revised and extended version of the first edition that became a market success with six reprints since 1998. Surfactants and Polymers in Aqueous Solution is broad in scope, providing both theoretical insights and practical help for those active in the area. This book contains a thorough discussion of surfactant types and gives information of main routes of preparation. A chapter on novel surfactants has been included in the new edition. Physicochemical phenomena such as self-assembly in solution, adsorption, gel formation and foaming are discussed in detail. Particular attention is paid to the solution behaviour of surfactants and polymers containing polyoxyethylene chains. Surface active polymers are presented and their interaction with surfactants is a core topic of the book. Protein-surfactant interaction is also important and a new chapter deals with this issue. Microemulsions are treated in depth and several important application such as detergency and their use as media for chemical reactions are presented. Emulsions and the choice of emulsifier is discussed in some detail. The new edition also contains chapters on rheology and wetting. Surfactants and Polymers in Aqueous Solution is aimed at those dealing with surface chemistry research at universities and with surfactant formulation in industry.

The 52nd Colloid and Surface Science Symposium of the Divis ion of Colloid and Surface Chemistry of the American Chemical Society was held in Knoxville, TN, June 12-14, 1978, and one of its Sections was devoted to the topic of Solution Chemistry of Surfactants. Although it was billed as the Section on Solution Chemistry of Surfactants, but it was indeed a veritable inter national symposium on this topic as 51 papers by about 100 con tributors from 12 countries were listed in the program. The present volume and its companion volume 2 document the proceedings of the above-mentioned Section on Solution Chemistry of Surfactants. In 1976 there was held an international symposium on Micellization, Solubilization and Microemulsions in Albany, l the proceedings of which have been chronicled in two volumes. A great deal of material dealing with micelles contributed by a legion of prominent researchers constitutes these volumes but a few subtopics were not adequately covered; so it was deemed appro priate to cover these topics as well as the recent progress in the general area of aggregation of surfactants in this Section. Also as it is the amphiphilicity or amphipathicity* of a surfact ant molecule which is responsible for both adsorption at inter faces and aggregation in solution, so it was considered quite apropos to include the topic of adsorption at interfaces in this Section. Concomitantly, the present volumes not only cover the aggregation phenomena but also the adsorption at interfaces.

This and its companion volumes 7,8, and 9 document the proceedings of the 6th International Symposium on Surfactants in Solution (SIS) held in New Delhi, India, August 18-22, 1986 under the joint auspices of the Indian Society for Surface Science and Technology, and Indian Institute of Technology, Delhi. As this symposium was a landmark -- it represented the tenth anniversary of this series of symposia -- so it is very apropos to reflect on how these symposia have evolved to their present size and status. The pedigree of this series of symposia goes back to 1976 when the premier symposium in this series was held. Actually in 1976 it was a modest start and it was not possible at that time to gaze at the crystal ball and predict what would be the state of affairs in 1986. For historical purposes, it should be recorded here that the first symposium was held in Albany, NY, under the title "Micellization, Solubilization and Microemulsions"; the second symposium was christened "Solution Chemistry of Surfactants" and was held in Knoxville, TN, in 1978; the venue for the third symposium in 1980 was Potsdam, NY, and it was dubbed "International Symposium on Solution Behavior of Surfactants: Theoretical and Applied Aspects.
