JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 625 Book Reviews HANDBOOK OF MOISTURE DETERMI- NATION AND CONTROL--PRINCIPALS, TECHNIQUES, APPLICATIONS, Vol 3, by A. Pande. Marcel Dekker, Inc., New York, 1975, XI + 289 pages. Price $33.50. This is the third volume in a four volume series which uses continuous pagination. The index appears only in the final volume. Volumes 1 and 2 were reviewed in previous issues of the Journal (26,429 (1975) 27,244 (1976) ). The four chapters contained in this volume are "Moisture in Tex- tiles," Moisture in Bagasse, Wood, and Paper," "Moisture in Foods and Allied Agricultural Products," and "Moisure in Soils, Sands, Concrete and Silica, and Silicates." Although, each chapter does contain specific needs unique to that particular area of expertise, there is much of a gen- eral nature that is potentially of great interest to cosmetic chemists. The stndy of water in wool has al- ways had obvious similarities in the hydration properties of human hair. Even some aspects of skin hydration find parallels in the dehydration and rehydration of polymers, paper, etc. Those working with talc and other silicates may find that some unique problems of moisture content may have already been resolved in very different contexts of other industries. Obviously, the cosmetic chemist is probably not likely to find his spe- cific application problem clearly laid out for him. He will, however, tlnd similar problems and needs clearly developed. Recognizing the analogy, he may tlnd an obvious solution to his specific need. Certainly, a perusal of these chapters should lead to a better understanding of equivalent truly cosmetic applications in mois- ture determinations in both finished product and in raw materials. Although, the post 1965 literature may be minimal, it should be men- tioned, as for a review of an earlier volume, that this is the apparent cut- off date for virtually all references.- Joan H.

626 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS Tox•co•.oG¾ ANNUAl. 1974, Edited by Charles L. Winek. Marcel Dekker, Inc., New York, 1975, 344 pages (il- lustrated). Price: $29.50. Toxicology Annual 1974 is a com- pilation of papers on selected topics of current interests and represents several disciplines covering a wide range of topics in the field of toxicol- ogy. Included in the volume are arti- cles on veterinary toxicology, nar- cotic drug dependence, the current status of saccharin, and postmortem drug level changes. An excellent chapter by E. Bueh- ler in this book, which is of interest to cosmetic chemists, is on test meth- ods to predict potential occular haz- ards of household substances. The index appears adequate, and the wide range of topics covered will make the book of interest to toxicologists in many fields. The ar- ticles are written by outstanding sci- entists and researchers, and the book should be a useful, though not vital, addition to the libraries of pharma- cologists, toxi. cologists, physicians, pharmacists, and veterinarians.- Ca•m•.Es O.

The comprehensive coverage of the area of industrial pharmacy by 44 tenured nationally and interna- tionally recognized experts including industrial scientists, pharmaceutical educators, and research and devel- opment managers makes this book exceptionally valuable for individu- als seeking a thorough orientation in contempora•3• industrial practice. The editors, in this second edition of their book, include 4 new chapters discussing preformulation, produc- tion, packaging, and drug regulatory affairs, which supplement 22 exten- sively revised and rearranged chap- ters to reflect the numerous advances in the technology and regtflato•3• ac- tivities affecting modern industrial pharmacy practices. All 26 chapters are extremely •vefl illustrated with numerous charts, tables, diagrams, photographs, etc., and painstakingly referenced. The chapters titled "Theories of Dispersion Techniques .... Pharma- ceutical Suspensions .... Emulsions " "Semisolids .... Pharmaceutical Aero- sols " and "Sterile Products" should be of particular interest to cosmetic chemists who are involved in basic formulation work. Since these chap- ters stress the development of theo- retical concepts and principles, rath- er than simply review the subject matter, they become extremely use- ful to the formulation chemists who desire to endeavor outside their own area of specific expertise. Lacking, however, from these chapters is a thorough discussion of the rheo]ogi- cal properties governing polyphasic systems, and the cosmetic chemist should not turn to this book in search of a quantitative indepth interpreta-
