It SOURCES OF INFORMATION FOR THE COSMETIC INDUSTRY 343 on tragacanth, karaya, and arabic. Each gum is treated separately with properties given in detail. If you are interested in sorbitol, the Atlas Powder Co. presents con- siderable data on that product in a bulletin entitled "Sorbitol." A 44-page brochure, "Precipi- tated Calcium Carbonate" by the West Virginia Pulp & Paper Co. discusses the history, manufacture, properties, and applications of Snow Top and Caltec. Other bulletins on various topics that are outstanding and well worth retaining for permanent reference are the Atlas Powder Co.'s "Sur- face-Active Agents" and "Drug & Cosmetic Emulsions" also the booklets on Sodium CMC issued by both the du Pont Co. and Her- cules Powder Co. How many of you have noticed how much of the advertising lay- outs in the technical and trade journals are chemically informative ? Here is a source of "hot" technical knowledge giving brief data on specifications, properties, uses, and typical reactions of new chemicals. These pertinent data on industrial chemicals are so necessary in the day-by-day work of research chem- ists and chemical engineers that the editors of the American Chemi- cal Society have devised a plan to disseminate this information in a concise, usable, and readily avail- able form. Paid advertisements are presented in card form giving all information a user would be likely to need. The first installment of these I&EC F.act Cards appeared in the September, 1950, issue of Industrial & Engineering Chemistry. It is an experiment and, if received enthusiastically, a regular insert of Fact Cards will be published in each issue of this journal. STATISTICS A search for statistics is so fre- quently time-consuming that any methods which provide short cuts are particularly to be desired. Data on consumption of chemicals are relatively rare. The most com- plete statistics are those for alcohol published by the Treasury De- partment. But these indicate the ideal. In spite of all the statistics published by the government and by trade associations, it is usually difficult to learn the total output of a certain commodity, or how much of this output is being used up. In 1945 the United States Govern- ment's Bureau of Foreign and Do- mestic Commerce resumed pub- lication of the "Industrial Reference Service," Part 2, dealing with chemi- cals, drugs and pharmaceuticals. One issue of this service was a special survey entitled "Synthetic Aro- matics-Flavor and Perfume Mate- rials." The revived service has also issued "Synopses of Information" on glycerin, tartaric acid, carnauba wax, urea, and other chemicals useful in our industry. These documents cover specifications, uses, statistics on output, prices, and consumption. Information of this type has been widely diffused in books, magazines, and pamphlets, and often is inconsistent among sources.

344 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS With the recent publication of "Industrial Chemicals" by Faith, eta/. (47), data on the economic aspects of a select group of 106 common chemicals are readily avail- able. It includes figures on pro- duction in chart form for the last twenty years a chart covering the twenty-year price range of the prod- uct and a tabulation of the per- centage distribution of the chemical among the various uses. The chief disadvantage inherent in a book o this kind is that the statistical matter is never up to date. This fault may be obviated, how- ever, by the new and important chemical data service now being offered by the Stanford Research Institute. Known as the "Chem- ical Economics Handbook" (48), it presents fundamental economic data on production, sales, consumption, prices, exports, and imports of individual chemicals and end-chemi- cal groups. Service is on a sub- scription basis and is in the form of standardized 81/2 X l 1-in. sheets carrying data on one subject, in graphical and tabular form and carrying back to 1910. Only new sheets will be issued during 1950 and 1951--about 400 data sheets a year--but in subsequent years re- vised sheets will be issued along with additional new ones. GOVERNMENT SOURCES The government is a prolific pub- lisher issuing much that is useful to our industry. We have already discussed the comprehensive sum- maries furnished by the Industrial Reference Service, and the work of the Food and Drug Administration in developing special analytical methods for cosmetics. In 1949 the Division of Cosmetics published its compilation of methods of analy- sis for coal-tar colors (49). A sup- plement of revisions and additions was made available in April, 1950 (50). The Technical Library of the Quartermaster Research and De- velopment Laboratories prepared abstract bibliographies several of which are worthy of note. "Con- tainer Coatings" is the subject of one of these technical compila- tions which provides descriptive references on 157 studies covering the period from 1941 to 1949 (51). Another survey includes information on natural and synthetic pepper flavors emphasizing chemical con- stitution and the chemistry and synthesis of constituents (52). Through the "Bibliography of Scientific and Industrial Reports" (53) captured German information is publicized for distribution. A report entitled "Synthetic Aromat- ics, Perfumes, Isolates and Their Derivatives" (54) supplies data on such aspects of German aromatic chemical manufacture. The nature and content of the report "German Cosmetic, Perfumery and Soap For- mulae" (55) is indicated by the title. The status of developments in detergents was reviewed by Hoyt in a paper "Synthetic Deter- gents" (56). Research progress on Tylose HBR, the German methyl cellulose, was reported by Hoyt(57).
