Book Reviews COSMETICS: SCIENCE AND TECHNOL- ocY, 2nd Ed., Edited by M. S. Bal- sam and Edward Sagafin. Wiley In- terscience, New York, 1974, Vol. 3, xii + 787 pages, indexed. Price $36.00. The long wait for the completion of the second edition of "Sagarin" has finally ended with the publica- tion of Volume 3, which generally parallels the organization of Parts I, III, IV, and V •of the first (1957) edi- tion. This-is an important contribu- tion to the industry, unfortunately marred by the delay in publication. Of the 13 chapters, nine are tech- nical in content. Only two of the 846 references in these nine chapters are to literature after 1968. A technical lag of six years severely limits the value of this new work. With a few exceptions, the new matehal in the book occurs in those chapters, where the distinguished Editorial Board has selected new au- thors. Most of the first edition au- thors limited themselves to minor up- dating. One exception is the amazing "Effie" Wall who doubled the length of her original history, incorporating tremendous detail about the last 100 years-a real contribution. The chapters on industry status, skin, sweat, and sensitivity testing are completely new, and generally excellent, although inevitably some areas in each chapter are treated briefly. Fisher's chapter on sensitiv- ity testing is succinct and pragmatic, providing useful guidance. The chapter on quality control has a modernized introduction, l:ut few changes in the previous detailed sta- tistical treatment. Extensive revision is valuable in the chapter on preser- vation, but unfortunately it is brought up to date only to 1968. Estrin's chapter on self-regulation describes the massive effort by CTFA for technical reeducation of the industry in recent years to bring it into the twentieth century. The legal chapter succinctly covers events of the 1960's. but unfortunate- ly, not the turmoil of the last two years. Zuckerman's chapter on color reflects the impact of the Color Ad- ditive Amendments of 1960. The chapter on emulsification ex- pands the HLB table and adopts a more useful approach to examples. 427

428 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS Thc changes in the alcoholic frag- rance chapter are limited to a few added sentences on possible chemi- cal interactions. In the chapter on performance evaluation, new de- tailed case histories offer guidance to panel testing techniques, but few cautions about the pitfalls. The proofreading in this volrune is magnificent-there are few errors. The paper is of good quality, and the type is clear. Division of the work into three volumes is probably desirable, but a one-volume com- pendium does have virtues. The cumulative index helps, but is really inadequate for a reference work of this importance. Although the total number of pages has been substantially in- creased in the three-volume format, the actual increase in printed matter is only about 10% in view of the re- duction in page size.--MuaaAY BEg- rocK-Chesebrough-Pond's Inc. REVIEW OF EMULSIONS AND EMUL- SION TECHNOLOGY (Part II), Edited by Kenneth J. Lissant. Marcel Dek- ker, Inc., New York, 1974. 530 pages. Price $48.50. Part II of the two-part Volume 6 on "Emulsions and Emulsion Tech- nology" consists of chapters 0 through 13. Generally speaking, the criticisms leveled against Part I of the volume [1. Soc. Cosmet. Chem., 25, 681 (1074)] are applicable to Part II except that the proofreaders appear to have done a better job on this book. However, it would be very di•cult to recommend this volume to cosmetic chemists, since there is only one chapter that would be ap- plicable to their needs. Considering the outlandish price for Part II, this reviewer would find it personally dif- ficult to spend $48.50 for one chapter consisting of 233 pages at that ratc a book on the same subject matter would cost over $100.00! Actually, with more judicious planning, the editors could have included the chapter on cosmetic emulsions in Part I, because there is a more direct inter-relationship between it and the chapters in Part I on medicinal emul- sions, microemulsions, agricultural applications, etc. Why the chapter on cosmetic emulsions was grouped with such things as hydraulic fluid emulsions and emulsions in the pa- per making industry remains a mystery. With regard to the chapter on cosmetic emulsions itself, author Charles Fox is well known to cos- metic chemists, having been quite active in the Society and a past presi- dent of the group. The material is well organized, basic in its approach to cosmetic applications, and han- dled in a thorough and understanda- ble manner. There is a good section on hydrophilic colloids and their role in emulsion stability, more than one normally finds in a treatment of this kind it is an excellent first introduc- tion to the neophyte cosmetic chem- ist, and also a good basic reference for the experienced cosmetic formu- lator. It is too bad that this chapter was not published as a monograph on its own in a less expensive edi- tion.--ROBEaT MAnCH•SOTTO--Re- search Corporation.
