JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 487 tural Chemists, Inc., Washington 4, D.C. 84pages. Price $4.00. This booklet describes analytical procedures which are currently used in the laboratory of the Division of Color and Cosmetics of the Food & Drug Administration. These procedures are authoritative because they are used for the analyses re- quired for the enforcement of the Federal Food, Drug and Cosmetic Act. However, the proc.edures are equally authoritative since they are based on sound chemistry and on Inethods widely adopted in the cosmetic industry. Three chapters in this book, which comprise approximately one third of the total pages, are of particular interest. The first of these is concerned with the analysis of creams. This chapter is equally useful for the analysis of lotions and, with minor modifications, can be adapted for the analysis of various types of hair dressings, brilliantines, etc. This is .especially true if the information •n the chapter on creams is ' ' ' with that in tnc corn Dlnect L•_ A chapter on the analysis of lipsticks. The third chapter which appears of major interest to the reviewer is the chapter on the analysis of shampoos, which describes the separation of a variety of detergents and their qualitative identification. Other important chapters are devoted to the analysis of nail lacquers, of hair dyes, and of permanent waving products. Each section is devoted to qualita- tive analysis as well as to quantita- tive methods of assay. A number of flow sheets are presented for the qualitative analysis of cosmetics. From the numerous infrared spectra included in this volume, it must be concluded that the F.D.A. places particular emphasis on this ex- tremely useful method of qualitative determination. Over 50 infrared spectral curves are included in the text. Admittedly, this is not a comprehensive collection, but it should prove useful to the cosmetic analyst who is confronted with a variety of qualitative identification problems. The reviewer was surprised to find no mention made of additives used in creams which are routinely sold to the American.publ)c. For ex- ample, no mention is made of hormones and skin lighteners which are frequently used in creams and lotions. Similarly, a large number of other cosmetic preparations are not included in this book. Facial makeup products and the identifica- tion or separation of various pig- ments used in them are not covered. Shaving preparations (tube, jar or aerosol), pre-electric shave lotions, and after-shave lotions are not mentioned in this volume. Aserious omission from this volume is the lack of attention given to eye makeup products. It is well known that the F.D.A. has developed methods for the analysis of eye products and for •1_ _ i ..1 •'l• •.' ' uL• luentmcation of pigments in such products. It is surprising to find that these methods and analyses were not made part of this book. Another omission is the absence of spectral data of components of sunscreening preparations which are identifiable by their ultraviolet and infrared spectra. Finally, it would have been desirable to include a series of qualitative and quantita- tive procedures for various germici- dal and antimicrobial substances which are used commonly in cosmetic preparations. Regardless of these omissions, the booklet is an important and significant contribution to cosmetic science and will be of value for all who are involved in analytical procedures.--M. M.

488 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS FUNDAMENTAL PRINCIPLES OF B^c- TERIOLOa¾, by A. J. Salle. Mc- Graw-Hill Book Co., Inc., New York 36, N.Y. 1961. 812 pages, illustrated and indexed. Price $11. Every chapter of this fifth edition of a work nearly twenty-five years old has been updated, according to the preface. A significant amount of the text appears for the first time, hence the reader is cautioned not to accept the statements as established fact. In a random checking of the text one fails to find reference to the self-sterilizing properties of certain shell fish and plankton, although the round-up of the bacteriology of the sea is otherwise quite thorough. While there is a considerable re- view of the bacteriology of water, nothing is said about the maximum bacterial count of drinking water. The chapter on bacteriophage is well illustrated. The germicidal proper- ties of the gly. cols and the effect of surfactants is inadequately de- scribed. The book perhaps is a good class text, but it fails to let the student know some of the developments since, say 1950. Although the references heavily cover early years, the subject after 1950 is but sparsely reviewed. Yet a smattering of references up to 1960 are given. For those wanting very basic bacteriological information, this book will be helpful. The subject is clearly and well presented.--M. G. DEN', THE BEH^V•OR OV PL^STICtZEaS, by Ibert Mellan.

Most of us think of plasticizers as simple substances added to both rigid and semi-rigid plastics to keep their substance together for ex- tended periods of time--to ensure toughness, increase flexibility or to improve stability. Among the items treated in this book are the mechanism of plasticiz- ers, retentivity, efficiency, flexibil- ity, tensile strength, shrinkage, creep behavior and internal plasticization. Table 2 on pages 28-29 seems transposed. The list of sources commencing with page 261 is a valuable addition, but it does not seem to be tied in with a given plasticizer. It is regrettable that the refer- ences are so few furthermore, most of them date to years before 1950. The index is very insufficient. If one wants to learn anything about plasticizers for nylon, polyethylene, polypropylene or polystyrene, one has to look for it in the text, if the data is there. The index does not list it. And yet the book contains many valuable data formerly scattered throughout the literature.--M. G. DEN. QUANTITATIVE METHODS IN PHAR- MACOLOGY, edited by H. De Jonge. Interscience Publishers, Inc., New York 1, N.Y. 1961. 391 pages, illustrated. Price $13.25. This book is not for the beginner. It presumes a considerable knowl- edge of the subject. It is in fact the proceedings of a symposium held at Leyden in 1960. The book, typical of others re- porting a "proceedings," presents an exchange of knowledge of quan- titative pharmacological methods. Discussions of the papers are also included. A casual examination shows: "distributionfree" not hyphenated biassed not unbiased the grammar, as is often the case in translating into English, is not the best, as in the discussion on page 168.
