JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 149 In any of these three cases, and in the case of the various forms of two-dimensional chromatography which are mentioned briefly, the practitioner would soon be obliged to consult more specialized works Hummel's monograph on the infra- red analysis of surfactants, for exam- ple (the majority of the spectra in the appendix are reprinted from this work). This will not be the case for liquid-liquid extraction and ion-ex- change methods for which this book is virtually an encyclopedic working manual. Advocates of gel permeation chromatography will be disappoint- ed to find that little or no mention is made of this technique even in the section on the separation of polygly- CO1S. The chapter on quantitative analy- sis has been considerably expanded and reflects the recent interest in the determination of very small quanti- ties of surface-active material in effluent sh'eams, groundwaters, etc. Techniques for concentrating large volumes of dilute solutions are dis- cussed. The appendix includes a compila- tion of surface-active materials by commercial name and nominal chemical structure arranged accord- ing to the classification used in the text. This is now a valuable 47-page monograph in its own right. The complexity of this vast array may be seen as justification of the elaborate classification criteria used, which are rational but by no means intuitively obvious. A familiarity with these cri- teria is required for effective use of the book and the acquisition of it is not an effortless task. The second edition of "Rosen and Goldsmith" certainly appears to be a highly successful rejuvenation of a standard work of proven merit.- ALA• M.

This compilation represents a use- ful starting point for a novice in the field of cosmetic development and could be a useful adjunct to the vet- eran. It is divided into five major sec- tions, the lb'st of which is a Formu- lary consisting of sales literature from seven well-known chemical suppliers to the cosmerle industry. As such, it is subject to the limita- tions inherent therein. The formulas provided generally are meant to of- fer a vehicle for displaying the wares of the suppliers, and this is their prime purpose. It must also be recog- nized that because of this they are not necessarily ready for consumer use test or production, although some may be quite serviceable and suit an immediate need. Within this limitation they do, however, provide a basis for starting fordrelation and aid in provoking thought. Some minor indexing problems were found two formulas were not found where listed, and the listing of Emulsion has three examples al- though much, if not most of the Formulary, is devoted to this topic. Probably due to the speed with which the regulatory agency acted, hexachlorophene was left included in some of the formulas without

The second section is devoted to color regulations and was prepared by an eminent authority, Samuel Zuckerman, who most assuredly understands the subject. One diffi- culty in this area is getting the latest information into print quickly enough to be completely current. The exact date of the article should have been included, so that if the reader wished to update himself, he would have a starting point. A Cosmetic Thesaurus is provided in the third section which should be welcomed by anyone confronted with the task of setting up an infor- mation retrieval system. It appears to be most informative and useful. An interesting discussion and list of sources of information is present- ed next in the Information Sources section. Although over the years one has contact with many of the sources listed, this organized presentation serves as an excellent refresher and should be extremely informative to someone new in the field. The Patent section provides a good source for patent information, and, as indicated, its cost to an in- dividual would be more than the cost of the total volume.-W. J.
