424 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS constants to which are added boil- ing points and other data. Puri- fication methods and bibliography complete the volume. In going over the lists of solvents, practically all those commonly used in toilet goods were included. Tet- rahydrofurfuryl alcohol (or its es- ters) terpineol, hexylene or butyl- ene glycol are not included. Some plasticizer solvents, such as tri- cresyl phosphate are not given although camphor is included. Even so, the book is thorough with no errors noticed. The price is moderate.--M. G. r)ENAVARRE. COMPREHENSIVE INORGANIC CHEM- IS,R¾. Volume III, The Halogens, by R. C. Brasted. D. Van Nos- trand Co., Inc., New York 3, N.Y. 1954. 250 pages, 6 X 9 inches, indexed. Price $5.00. The third of an eleven volume series, discusses the chemistry of fluorine, chlorine, bromine, iodine and astatine. In each case, the history, prepara- tion, physical and chemical prop- erties, various reactions, and uses are included. Unfortunately, only two Freons are mentioned. No Genetrons or other fluorinated hydrocarbons as refrigerants or propellants are given. This is a minor point, however. Additional to the contents given abow, chapters on the hydro- halides, oxycompounds, interhalo- gens and pseudohalogens are in- cluded. Typical of the series, the book is well manufactured and fairly priced. --M. G. I)ENAV^RRE. TEXTBOOK OF ORGANm CHEMISTRY, by Carl R. Noller. W.B. Saunders Co., Philadelphia, Pa. 1953. 643 pages, 61/4 X 91/2 inches, illus- trated and indexed. This is an orderly presentation of the subject starting with the basic principles of the science and advanc- ing through the pages into the more complex chemistry of the day. An unusual and interesting addition is Appendix A--Pronunciation--six pages. The reviewer finds that he and his contemporaries are all mis- pronouncing many chemical terms. Silicones are discussed in four pages aliphatic sulfur compounds get fifteen pages both are ade- quate. The chapter on oils, fats and waxes is too scanty a coverage of a large subject. Phthalocyanines are not included in the chapter on dyes. The toluidines and p-phenylene- diamines are mentioned in the chap- ter on aromatic amines. FD&C colors are not mentioned. Fluoro- organics are included. It is a good text and a readable reference.--M. G. I)ENAVARRE. THE SCIENCE OF COLOR, Commit- tee on Colorimetry, Optical Society of America. Thomas Y. Crowell Publishing Co., New York 16, N.Y. 1953. 385 pages, 7 X 10 inches, illustrated and indexed. Price $7.OO. In preparation since 1932 this definitive account of the science of color opens in a popular vein and gradually carries you into the increasingly technical aspects of color, according to the jacket on the book. The committee who pre- pared this book consists of twenty- three people with L. A. Jones of Eastman Kodak Company as chair- man. Four additional people from "Kodak" are on the committee. Nine chapters cover everything from the historical uses of color, through the psychological, anatom- ical, physical and measurement of color. Twenty-five color plates and over a hundred black and white figures illustrate the text.

BOOK REVIEWS 425 The book includes basic review of the color science and carries on into the more exact definition and meas- urement of color. One can find much use for this book in the make-up end of the cos- metic industry. The committee is to be commended for accomplishing a task which is truly unique.--M. G. I)ENAvARRE. CLAYTON'S THEORY OF EMULSIONS AND THEIR TECHNICAL TREATMENT, 5th revised edition, by C. G. Sum- ner. The Blakiston Co., Inc., New York 22, N.Y. 1954. 669 pages, 6 X 91/4 inches, illustrated and indexed. Price $14.50. It is eleven years since the fourth edition appeared the present revi- sion is written by Dr. Sumner, the original author being unable to do the work. Some chapters are con- densed, others expanded to show the deletion of out-dated material and the addition of the new. Silicones as defoamers are given in a small footnote only in the chap- ter on surface phenomena. Under emulsifying agent, The Wetting Agent Bulletins of the dmerican Perfumer are not mentioned. Most of the published work appearing in THE JOURNAl, OF THE SOCIETY OF COSMEWm CHEMISTS has not been mentioned. The chapter on emulsifying agents, while expanded and cover- ing many types of emulsions, is weak on drug, cosmetic and flavor emul- sions. The almost 50 pages could easily have been doubled. The section on technical opera.- tions in preparing emulsions •s fairly complete. It includes ultra- sonic methods. Clayton's "Theory of Emulsions" is a classic in its field. It bridges theory with fact. If the theory is not completely understood, cer- tainly the practice is just as much an e.nigma to emulsion technolo- gists •n industry. It is one thing to work with pure systems, and another to work with variable mixtures. So those en- trusted with the task of making safe, stable cosmetic emulsions are always interested in any phase of the subject that may help in their work. This revised edition has been needed. You will want it for refer- ence.--M. G. I)ENAv^RRE. TEXTILHILFSMITTEL UND WASCH- ROHSTOFFE, by Kurt Lindner. Wissenschaftliche Verlagsgesell- schaft M.b.H., Stuttgart 1, Ger- many, 1954. 976 pages, 63/4 X 91/2 inches, illustrated and indexed. Price 113 DM. Here indeed is a monumental book, Germanic in coverage, on materials used in textile processing, their chemistry and patent back- ground. The book is divided into four parts, namely, basic organic mate- rials, the manufacture of textile chemicals, special materials and methods of analysis. Each part is a book in itself. The section dealing with the man- ufacture of textile chemicals is almost 300 pages long, covering all main types of materials. Surfact- ants most widely used are included. In fact the material on ampholytes is one of the most complete this reviewer has seen. The Tego com- pounds are described but the Deri- phats and ampholytic Miranols are not mentioned. The American polyacrylates are not given. The appendix lists manufacturers from Switzerland, Austria and Ger- many French, Belgian, British, Italian and U.S. products are hardly mentioned. Each company's prod- ucts are listed in continuous style, a very unmethodical presentation.
