SOURCES OF INFORMATION FOR THE COSMETIC INDUSTRY 335 ing a statistical study of the results. Having established the fact that a given formulation produces a lacquer which satisfies the require- ments with respect to color, appli- cation properties, and wear resist- ance, the tests outlined will enable the control laboratory to be sure that the lacquer delivered meets the specifications. CURRENT SOURCES OF INFORMATION FOR THE COSMETIC INDUSTRY* By GERTRUDE SCHUTZE Research Librarian, Bristol-Myers Co., Hillside, N. As THE TITLE suggests, my primary concern is with the current sources of information. Although the origins and early developments are fascinating, this aspect of the literature has already been reported. Edward Sagatin traced the back- ground of the literature of per- fumery when he spoke before this group in December, 1947 (1). He has recently published a charming article dealing with the popular literature of this industry (2). Florence Wall has surveyed the historical background of cosmetics (3) and predicted that qualified research workers would make the major contributions to our literary resources. In the 20th century science and research literally command the field. All the wonderful advances in this great industry are reflected in its literature. Technical information of interest and value to the cosmetic * Presented at the December 5, 1950, Meet- ing, New York City. chemist is to be found in various publications of which books, period- icals, house journals, publications of professional societies, trade cata- logs, technical reports, specifica- tions, and patents provide the main sources. The chemist, the manu- facturer, the societies and associ- ations, and the government are fertile sources of informational material. Continental texts will not be considered in this session since our time is limited and for the important reason that English is the most important language of publications in the fields of pharmaceutical, cosmetic, and perfume chemistry. The new "Encyclopedia of Chemi- cal Technology" (60) contains many articles of interest and value to the cosmetic industry. Florence Wall did the section on cosmetics in Volume IV and the section on hair preparations will appear in a later volume. Although texts are not the real life-

336 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS blood of the practitioners' library, books are, of course, essential for reference. Certain well-known works by Poucher, Parry, Gilde- meister and Hoffmann, and others are not discussed here because they have been replaced by up-to- date, modern compilations. There are now available several com- prehensive treatises giving full de- tails on all raw materials, practical topics, and concise explanations of all basic scientific principles bearing upon cosmetics. Partic- ularly worthy of note in the cosmetic field are Harry's "The Principles and Practice of Modern Cosmetics" (4) and deNavarre's "The Chem- istry and Manufacture of Cos- metics" (5). Harry's work con- sists of two volumes, the first en- titled "Modern Cosmeticology." The author stresses the scientific and therapeutic side of cosmetics and gives a good account of the chemical and physical basis of this subject. Numerous formulas are provided as well as the technical. details of their manufacture. The companion vol- ume, known as "Cosmetic Mate- rials," has arranged alphabetically in monograph form the mass of mixed information condensed from trade and scientific journals and commercial brochures concerning the basic materials used in modern cosmetic formulation. The novelty of this dictionary lies in the atten- tion devoted to the dermatological action of each material. No such work has appeared dealing essen- tially with this aspect. It is a book of first-rate importance. The major part of deNavarre's book is devoted to the chemistry of cosmetics. An excellent feature is the inclusion at the end of each chapter of a digest of patents for the specific product discussed. A practical handbook outlining the formulation and production of cos- metics is Thomssen's "Modern Cos- metics" (6) which is the third edi- tion of Chilson's book of the same title. There is no description here of the chemical aspects of the subject or the bacteriological or physiological principles involved. As far as production methods and the manufacturing approach are concerned, it is the best practical book since Poucher. The perfumery field has made several outstanding contributions to its literary resources within the past decade. Prior to 1948, the most up-to-date comprehensive treatise on essential oils was the German classic by Glidemeister and Hoffmann of which the third edition appeared in the early thirties. Recently Ernest Guenther and collaborators have issued four of the proposed five volumes of "The Essential Oils" (7). The first two volumes provide a vo- luminous up-to-date and reliable reference on the production, con- stituents, and analysis of these perfumery raw materials. Volumes 3 and 4 contain monographs on individual volatile oils. Those of technical and commercial value are given preferential and detailed treatment. For each oil there are data covering the history, produc-
