BOOK REVIEWS ORGANIC SYNTHESIS WITH ISOTOPES, by Arthur Murray and D. Lloyd Williams, Part I, 1146 pages, Price $25.00. Part II, 849 pages. Price $25.00. Interscience Publishers, Inc., New York 1, N.Y. These two volumes are a collec- tion of methods for making"labelled" organic compounds. No biological syntheses are described. In each case of several methods of synthesis, the authors chose a preferred or most feasible one. Part I discusses the synthesis of acids, acid derivatives, amines car- bonic acid derivatives, carbonyl compounds, ethers, heterocyclics, hydrocarbons, hydroxy and onium compounds, sugar, steroid and vita- min derivatives. Part II covers isotopic halogen and hydrogen compounds nitro- gen 15, oxygen 18, phosphorus 32 and sulfur 35 compounds. The syntheses are of interest in ordinary work because they give high yields. A thorough index to both volumes is found in Part II.--M. G. DEN. IoN EXCHANGE RESINS, by Robert Kunin. John Wiley and Sons, Inc., New York 16, N.Y. 467 pages, illustrated and indexed. Price $11.00. The fascinating and expanding field of ion exchange resins has called for this expanded second edi- tion (50 per cent). Much of the old material is rewritten and at least eight categories of new material have been added. In spite of this there is still a void in the cosmetic and toxicological areas. Thurman's work on deodor- ants if mentioned is not easily found. Ikai's work could not be found. The Hofmeister series on page 26 and Gustav Martin (page 292) are not given in the index. Indeed, the index could be substantially expanded. These minor discrepancies do not detract materially from the text which is a useful companion to the limited number of books on this subject. The illustrations are first class. In fact the whole presentation is excellent. No errors were noticed in going through the text.--M. G. DEN. INDUSTRIAL FATTY ACIDS AND THEIR APPLIe^TION, by E. Scott Pattison. Reinhold Publishing Corp., New York 22, N.Y. 230 pages, illus- trated and indexed. Price $7.00. The coverage of this book in- cludes processing and production of fatty acids with emphasis on prac- tical technology. The author is in an excellent position to bring together practical data which might not otherwise be available. Hence both author and his sources are to be congratulated. Sixteen chapters are contributed by twenty collaborators in addi- 190

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.
