Book Reviews SOLUTION CHEMISTRY OF SUR- FACTANTS, Volume ! and 2, K. L. Mittal, Ed., Plenum Press, New York, 1979, 961 pages. Price: Volume 1, $45.00 Volume 2, $39.50. The two volumes reviewed document the proceedings of the section on Solu- tion Chemistry of Surfactants at the 52nd Colloid and Surface Science Symposium held in Knoxville, Tennessee in 1978. The two volumes contain 49 papers which are organized into seven parts. Volume 1 contains three parts, the other four parts make up Volume 2. Each part deals with one of the topics covered at the Sympo- sium. Part 1 contains eight general overview papers. Part 2 contains twelve papers deal- ing with thermodynamics and kinetics of micellization in aqueous media. Part 3 contains five papers on the effect of solvent and micelies in nonaqueous media. Part 4 contains five papers dealing with reactions and interactions in miceliar media. Part 5 contains six papers dealing with microemulsions and reactions in microemulsion media. Part 6 contains seven papers on adsorption at interfaces. Part 7 contains six general papers. The subject matter covered in these two volumes encompasses a wide variety of research areas reflecting current inter- est in the theoretical and applied aspects of the chemistry of surfactant systems. While it is not expected that the cosmetic chemist will appreciate all the topics covered, there are indeed a number of papers which can prove very useful to cosmetic chemists engaged in developing products based on sound technical concepts. The papers dealing with the properties of surfactant mixtures, structural effects, solubilization, micelliza- tion and microemulsions provide interest- ing theoretical and application chal- lenges. There are very few typographical errors. Comprehensive references are provided after each paper, and the index is elabo- rate and useful. The two volumes should be a valuable addition to the libraries of cosmetic chemists.--AHMED F. EL- SHIMI--Clairol Incorporated. HANDBOOK OF AEROSOL TECH- NOLOGY, 2nd ed Paul A. Sanders, Ph.D., Ed., Van Nostrand Reinhold Co., Florence, Kentucky, 1979, 538 pages. Price: $27.50. The second edition of the Handbook of Aerosol Technology by the late Paul A.

162 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS product development, production, and control. Beginning with an interesting historical overview of the aerosol, Dr. Sanders carefully progresses through such areas as propellant properties, packaging components, formula systems, filling methods, particle size measurements, stability testing and flammability assess- ment as well as several elaborate chapters on aerosol foams and emulsions. The entries dedicated to aerosol containers and valving systems are most thorough and, except for only a very few minor developments within this industry since its publication, generally offers up- to-date information in good detail about these components. Basic steel, aluminum, glass (and even plastic) container compo- sition, function, and application are discussed, permitting a comfortable knowledge of this component of the aerosol package. Even special types of container concepts, such as those employing barriers and pistons, are included. Valving systems receive similar attention. The common types of valves and actuators are described with regard to component parts, construction, function and application. Special valves and actua- tors are also discussed with careful detail. A number of supplementary chapters authored by colleagues of Dr. Sanders present a series of interesting and useful topics in this issue. The ozone depletion theory is discussed from its chemistry up to the regulatory actions forcing the tran- sition of the aerosol industry. Other topics covered in these chapters are aero- sol sampling and analysis, useful in qual- ity control-realate functions, and a toxi- cological overview of fluorocarbon pro- pellants. This publication possesses a substantial amount of practical information espe- cially helpful in aerosol development. It is a most worthwhile addition to any aero- sol library.--A.
