JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 489 All in all, this is an advanced book with a strong European flavor. It is good for us to know more about methods used by others.-- I M. G. DEN. INTRODUCTION TO COLLOID CHEM- IISTRY, by Karol J. Mysels. Inter- iscience Publishers, Inc., New York I1, N.Y. 475 pages, illustrated and [indexed. Price $10. Twenty chapters are prepared for Itwo audiences in mind: (a) the Icollege senior (b) the industrial Ichemist or executive. The author luses a presentation that is good for icollege students possibly but not for either the industrial chemist or ex- ecutive, especially the latter. There is no section or chapter on emulsions. The subject is treated or referred to in twelve different places. This is the author's choice of course. Wouldn't it have been better to bring it all together at some point at the risk of some repetition ? As a reference, the book leaves the reviewer bewildered. As a text, a student can learn and under- stand the author's method because he has to. If the book is to sell to executives it will have to be con- siderably simplified, for executives are neither concerned with the ex- tensive mathematical explanations nor do they have the time to figure them out. Even so, there are nu- merous interesting expositions within the covers.raM. G. DEN. NEW HOPE FOR YOUR HAIR, by Irwin I. Lubowe. E. P. Dutton and Co., New York 10, N.Y. 253 pages, illustrated and indexed. Price Cloth Covered $3.95 Paper- back Edition $0.95. Realizing that the book is aimed at the public at large, one discounts the numerous impressions of lack of what some would call "scientific exactness." The layman has to have the material greatly simplified. To do so, many complicated explan- ations of our knowledge of hair must be tailored or altered. The author has been exceedingly clever at achieving this goal. However, on page 52, one wonders why hard candy is all right to eat in an anti-seborrheic diet but saccharin is to be used in place of sugar. Furthermore, if hard candy is per- mitted, why not soda pop? Both contain sugars, acids and flavors. Or does the author refer to cola type "pops ?" On page 147 p-phenylenediamine is not correctly stated and it is also misstated in the index. On page 148, second paragraph, the author misunderstands the Food, Drug and Cosmetic Act and regulations regarding hair dyes. The warning and patch test go on hair dyes made with coal tar colors which may be injurious to users (Sections 601a and 902a). On page 158 it is not usual for depila- tories to contain barium sulfate. In former times barium sulfide was used. Today, thioglycolates (one 1) are almost universally used, al- though some calcium and strontium sulfides are still in use. Finall. y, Chapter 19 appears to be m•s- named when it is called "Nutrition of Hair and Scalp." A cosmetic chemist could not get away with the implications of such a title. This is no attempt at denigrating the author's efforts. It does point up the difficulty of translating a scientific subject to lay language. For indeed it contains much lucid and factual information for the public. The prophylactic recom- mendations for saving one's hair could certainly be fruitful, for example. Results of work in the area of growing hair is for "tomor- row or the day after." The diffi- culties with transplants the prob-

The glossary at the end of the book along with the illustrations simplify the subject so all can understand it. One finds it difficult to put the book down once you start reading it. You will want it in your library.--- M. G. DEN. ADVANCES IN APPLIED MICROBI- OLOGY, Vol. I, edited by Wayne W. Umbreit. Academic Press, Inc., New York 3, N.Y. 304 pages, il- lustrated and indexed. Price $9.50. Another of the series of "Advances in--" by this publisher, which so many of us have used in the past. Whether there are sufficient ad- vances in applied microbiology to put out such a volume on an an- nual basis is hard to predict. In attempting to cover a range of subjects of interest to all people, one finds all too often that some of the meat is left out of the sandwich. The contributions fail to describe the real character of modern in- dustrial microbiology. The chapter "Factors Influencing the Antimicrobial Activity of Phe- nols," devotes but four lines to in- activation bynonionics. Elsewhere, flow patterns as actually used in mass production techniques in in- dustry should be included. Up-to- date information on the production of mutations is necessary. The principal value of these "Advances--" series is that usually there are a lot of references in the reviews. Obviously their very forte is their weakness in that the ad- vances in these areas are rapid and it is impossible to keep up with them in such a text which at best is over a year behin4.--M. G. DEN. THE CHEMISTRY AND TECHNOLOGY OF EDIBLE OILS AND FATS, edited by J. Devine and P. N. Williams. Pergamon Press, Inc., New York 22, N.Y. 1961. 154 pages, illustrated and indexed. Price $6.50. This text is the published record of the Unilever Conference held at Port Sunlight in 1959. The following are the titles of the papers presented: Physical and Chemical Properties of the Constituents of Edible Oils and Fats Fatty Foods and the Pattern of Their Consumption in the U. K. Processing of Oils and Fats for Edible Purposes The Analysis of Oils and Fats The Determination of Linoleic Acid Gas/Liquid Chromatography of Atheromatous Plaques Modern Spectroscopic and X-ray Techniques with an appendix on Methods of Analysis. Each address carries the dis- cussion that followed the presenta- tion. These contributions came from the Unilever Research staffs in England and Holland, hence reflect to a certain extent, the practice within that company. This is an useful little addition to your library on fats and oils.--M. G. DEN. SYNTHETIC METHODS OF ORGANIC CHEMISTRY, by W. Theilheimer, 14th yearbook. Interscience Pub- lishers, Inc., New York 1, N.Y. 549 pages, indexed. Price $29.50. Portions of this book appear both in German and English. It covers papers published during 1957-1959 on the broad subject of synthesis of organic compounds, improvement of known methods and also old proven methods.--M. G. DEN.
