JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 509 than the papers themselves. Some presentations are elementary, but most of them discuss new and ad- vanced phases in the field. The reviewer liked especially: Analyti- cal Methods in Assessing the Value of Perfumery Raw Materials by van den Dool. Ultra-violet Spectrophoto- metric Procedures in Essential Oil Examination by J. B. Stenlake and W. D. Williams. Heat Transfer in Cosmetic Manufacturing Processes by V. O. E. Bryant, and the whole group of biological papers which together with their discussions high- light the fact that cosmetic chemis- try is at the cross-road of either rigidly limiting itself to make-up items and simple emollient products or to extend its energies into treat- ment items which have their effi- cacy fully substantiated by pharma- ceutical and medical research.-- H.

In its modern usage, "aromatic char- acter" implies the possession, by an organic compound, of certain unique structural factors and resonance energies. With this sort of defini- tion for "aromatic character," the term nonbenzenoid aromatic com- pounds is no longer a contradiction, and materials like azulene and pyrrole can take their place in the aromatic family beside the parent benzene. This book brings to- gether for the first time in a single volume the subject of nonbenzenoid aromatic compounds. Nine authors of five different nationalities: Wilson Baker, E. D. Bergmann, D. P. Craig, E. Heil- bronner W. Keller-Schierlein, J. F. M. McOmie, Tetsuo Nozoe, P. L. Pauson and R. A. Raphael--meet in this book under the editorship of Mr. .Ginsberg. Of particular interest •s the first chapter on aromaticity. It is the theoretical springboard to the following chap- ters on specific nonbenzenoid aro- matic compounds. Azulenes, hep- talenes, pentalenes, tropones, tro- polones and cyclopolyolefins are among the several classes of com- pounds which are discussed. Heter- ocyclic compounds are treated only scantily, but the editor admits to this omission and begs our apology by way of other volumes having been published on this subject. The book is well indexed and docu- mented over 1600 individual refer- ences are listed. "Non-Benzenoid Aromatic Com- pounds" is directed primarily to an audience of research organic chem- ists. The cosmetic chemist may see materials of interest to him mentioned here, but he is unlikely to find any reference to their use- fulness in cosmetic formulations. The book is highly recommended as a reference book for inclusion in your technical library and as a book for general reading by those with a keen interest in some of the newer aspects of organic chemistry. --H.

510 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS PERFUMERY• COSMETICS AND SOAP, Vol. 3, 7th Ed., by William A. Poucher. D. Van Nostrand Co., Princeton, N.J. 1960. 260 pages, illustrated. Price $8.50. During an evening spent reading Poucher's latest revision of volume 3, "Being A Treatise on Modern Cosmetics," I felt a mounting dis- may that this particular work ap- pears under such a subtitle. As in most fields where a con- siderable technology has evolved, it is no longer possible for one man to cover all phases of cosmetics ade- quately. At best, all that can be done is to review the pertinent work done by hundreds of chemists in laboratories all over the world. Such a review, moreover, is best done by having different specialists cover each major subdivision. This was done by Sagatin in the encyclo- pedic work, "Cosmetics, Science and Technology" and will be done by deNavarre in his newest re- vision of "The Chemistry and Manu- facture of Cosmetics." Poucher does not approach the formulation of cosmetics as a sep- arate science. Curiously, one al- most has the feeling that he is treating it merely as an adjunct to perfumery. He presents only stock formulas, too often completely un- changed from the 1926 edition al- ready on my bookshelf. They are often of the simplest type and seem to be presented primarily as a basis for discussing the proper types of perfume ingredients to be used in each particular medium. In this sense, the work has some merit and its lack of modern formu- lation details can be justified some- what. It is a guide to perfumers rather than to cosmetic chemists. It gives a broad view of the industry, a historical background to which more current formulas can be com- pared and from which their per- fuming can be derived. Nevertheless,•even from this point of view there are gaps which are too large to be glossed over, viz: no where in the book is there any mention of aerosol products. Mod- ern antiseptics are ignored except for two formulas containing hex- achlorophene. Soap formulas pre- dominate-whether for emulsions, shampoos or dentifrices--with little recognition of the now common use of other surfactants Ignored is the fact that many natural products such as the unsaturated oils are now available in highly purified stable form with very low odor levels. The new generation of cosmetic chemists and perfumers owes a con- siderable debt to such men as Wil- liam A. Poucher. Lest my crit- icisms seem too unkind, I must add one more thought before closing. Many of the base formulations he presents have not greatly changed in the past few decades--such as powders, colognes and certain bath preparations and hair oils. Many others, although archaic, are still in use merely because they sell. Poucher's book will be found quite useful in these areas as well as for its valuable advice concerning the perfuming of the products.--R. L. GOLDEMBERO, Shulton, Inc.

The main title of this book leaves it open what type beauty is meant. The subtitle on the j acket--A History of Scent--is apt to arouse the cosmetic chemist's or perfumer's curiosity. On opening the book, a further subtitle becomes visible "A History of Perfume and Cos- metics." The Table of Contents shows the word "perfume" (or "perfumed") in the headings of 14
