JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 467 dyes which have been introduced in the past ten years. They react chemically with wool bifunctional vinyl sulfones can crosslink and therefore harden proteins, e.g. gela- tin. Also of interest to the cosmetic chemist are numerous other papers in this collection, covering such diverse subjects as the logwood dyes, true vegetable dyes, quercitins and other fiavones, carminic acid, direrpenes, vanillin, bixin, quino- noid dyes and optical whitening agents.--RoBE}•T L. Shulton, Inc. AUTOXIDATION AND A•rT•oxm^•rws, Vol. II, by W. O. Lundberg. Inter- science Publishers, Division of John Wiley & Sons, New York, London. 1962. 706 pages, indexed and il- lustrated. While Vol. I deals primarily with the fundamental chemistry in- volved, Vol. II applies the funda- mentals to the preservation of food- stuffs, fats, oils, petroleum, rubber, soaps, cosmetics and pharmaceuti- cals. There is an excellent chapter on the autoxidation of fatty com- pounds in living tissue and biologi- cal antioxidants. Fifteen authors, highly specialized in their fields, contribute ten chap- ters, covering the entire area of antioxidants and their application. There are four chapters relating to rancidity in foods and food products. Here, detailed discus- sions as to the nature of the rancid- ity and its measurement by ana- lytical procedures, together with information toward preventing it, are presen ted. Antioxidants suitable for use in foods are listed, covering their history, characteristics, selection and determination. Both hydro- lyric and oxidative rancidity relating to meats, dairy products, cereals, mayonnaise, grains, vegetables and miscellaneous items are discussed. Flavor reversion and related de- terioration include the causes, taste panel analysis, effect of metals, fractionation, deodorization and hy- drogenation. There are five excellent chapters that cover the subjects of oxidative polymerization, driers, petroleum, rubber and high polymers. Prod- ucts such as printing inks, anti- skinning agents, metallic driers, organic driers, gasoline, jet fuels, rocket fuels, lubricants, waxes, etc., are g•ven ample consideration. Lists of available antioxidants, pa- tents and literature references are also presented. The chapter pertinent to cosmetic chemists is that covering the sta- bility of the vitamins, soaps and cosmetics, pharmaceuticals, es- sential oils and other related prod- ucts. Also of interest to the cosmetic chemist is the final chapter dealing with living tissue fatty com- pounds together with enzyme activ- ity and vitamin destruction. Each chapter is furnished with numerous literature and patent references. This volume is an ex- cellent up-to-date practica] treatise on the subject of autoxidation and antioxidants and would be a valua- ble addition to the library of both the theoretical and product develop- ment chemist.--J^•s H.
