JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 191 tion to the principal author. Titles of the chapters range from "Fatty Acids Today and Tomorrow" through "Ozone Cleavage, .... Ap- plication of Soaps, .... Handling and Testing Methods." Although azaleic and sebacic acids are mentioned, a chapter on dibasic acids and derivatives would be very useful. Also desirable would be a chapter on insoluble metallic soaps. The subject matter is ably re- viewed by the various contributors. No errors were noted. The book is a valuable addition to a library in this industry.--M. G. I)EN. SYSTEMATIC ANALYSIS OF SURFACE- ACTIVE AGENTS, by Milton J. Rosen and Henry A. Goldsmith, Inter- science Publishers, Inc., New York. 1960. (Volume 12 of Chemical Analysis series, edited by P. J. Elving and I. M. Kolthoff). Xvii + 422pp. Indexed. Price $13.50. So pronounced a need existed for an authoritative treatise on the analysis of surfactants, and such immediate favorable experience oc- curred when pre-publication orders for this volume were shipped to the laboratories, that it is difficult to believe that there are more than a few laboratories with a serious in- terest in the analytical detection, separation, identification and esti- mation of surfactants, who do not now have and use Rosen and Gold- smith's "Systematic Analysis of Surface Active Agents." The authors have not only done a Herculean task in reviewing and critically evaluating the myriads of published methods on surfactant analysis, but have, as well, evaluated and published for the first time sev- eral methods and techniques that have been hitherto known only via personal communication, and have devised new tests which remedied the deficiencies in the body of knowledge available for organiza- tion into a systematic scheme of analysis, and thus made it possible to develop a rational and reliable systematic scheme. Their systematic analysis starts with classification by elemental analysis, and this is followed by identification of the functional groups present in the surfactant molecules. Adequate tabular sum- maries of the classes of surfactants established by these criteria are presented (including a generous 30-page list of representative com- mercial surfactants classified by the scheme), and detailed flow sheets of the analytical schemata are fully presented. Brief but adequate discussion of the analytical methods used at each step of the analyses are presented, and the authors do not hesitate to state their conclusions in re the strengths and weaknesses of alter- native techniques. The work is, however, primarily a working trea- tise for the analytical specialist, and does not delve deeply into the chem- istry of the analytical reactions from the standpoint of contiguous dis- ciplines such as the physical chem- istry of solvent partition, of dye- complex spectral shifts, or of micell- ular phenomena. The analytical chemist will find it a meaty, hard- packed treatise requiring close, at- tentive reading, and thorough study. The authors have done an outstand- ing job of organization and critical evaluation, but the analysis of surfactants remains an area where painstaking care is required, both in technique and in the interpreta- tion of results. It requires no great prescience to foresee that the development of surfactant analysis during the next decade will stem from and be closely related to Rosen and Goldsmith's "Systematic Analysis of Surface- Active Agents."--J.

192 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS COLOUR IN INDUSTRY TODAY, by Robert F. Wilson. The MacMillan Co., New York 11, N.Y. 1960. Price $8.00. The science of color, psychology and use, is briefly but thoroughly covered in this book. The author in easily understood layman's lan- guage covers the subject adequately for people who are interested in color but have only the most basic knowledge. His explanations of the science of color and color vision are interesting and usable by all classes of people interested in color, both those matching or duplicating shades and people using color such as paint- ers and interior decorators. The author gives numerous examples and color charts illustrating points brought out in his explanation of the science of color and color vision. The major portion of the book is devoted to the psychology of color, likes and dislikes, and the proper selection of color and their use in decorating. It is unfortunate that in the many color schemes suggested for many types of rooms and build- ings that he was only able to refer to color schemes by numbers and anybody wanting to make use of his suggestions would have to get the British Colour Council color charts. In summation this is a very worth- while book for anybody interested in the selection of colors for deco- rating or the effect of colors on per- sonnel employed under various con- ditions. It is also interesting to anybody who must make shade com. parisons or matching but is a novice in the field.--CHARLES R. KIRCHER, Kolmar Laboratories, Inc. SYNTHETIC ANALGESICS, Part I, Di- phenylpropylamines, by P. A. J. Janssen. Pergamon Press, Inc., New York 22, N.Y. 1960. 183 pages, indexed. Price $7.50. The present work reviews liter- ature through July 1958, utilizing extensive tabulation to present a vast amount of data in a form eas- iest to follow. Starting with the general structure for diphenylpropylamine, the author develops the structure for other therapeutically active derivatives. In this much previously unpublished data have been included. The nearly 550 references in them- selves are a valuable asset to any researcher in this field. Even though a goodly number of these are not mentioned in the text, they do help round out treatment of the subject. Reference No. 344 has somehow been completely lost. This is basically a chemistry book. Therefore pharmacology and other biological facets of the subject are present in minimal amounts. --M.G.DEN.
