PERIODICALS FOR COSMETIC CHEMISTS 49 PERIODICALS FOR COSMETIC CHEMISTS P. G. I. I.AUFFER* An analysis o[ the re[erences cited in the annual reviews ot cosmetic chemistry prepared by the author during each ot the past three years. T•4E PERIODICALS dealing with cosmetic technology are too •vell known to require listing, but many a cosmetic chemist must have asked himself which ones of the thousands of scientific periodicals should receive his attention. This article is an analysis of the references cited in the annual reviews of cosmetic chemistry prepared by the author during each of the pzfst three years. It should be noted that very few of the references cited dealt with cosmetics. Some dealt with skin, hair, nails, or materials used in cosmetic preparations. But the majority dealt with cells, cell particulates, proteins, enzymes, ageing, or the relations of molecular structure to biological activity. Most of them were written without any thought that the data and concepts they contained would be of use to cosmetic chemists. The references cited in these reviews were only those which were regarded as presenting novel facts, methods, or hypotheses, and which therefore could teach the cosmetic chemist something new about his task of making cos- metics safer, more efficacious, and more attractive. As the topics got further removed from immediate application, the choice of references became more selective. It should be emphasized that the selection of the references listed here was made entirely by one individual. Someone else would undoubtedly have compiled a somewhat different list. However, the concentration of almost half the references in a dozen periodicals is noteworthy. The commanding position of the weekly Nature, the British prototype of th• American weekly Science, is impressive. Outstanding discoveries in all fields of science are reported in Nature as brief letters, published long before the complete reports appear elsewhere. In Table 1 are listed the periodicals from which three or more articles were quoted in the review in any one year. Listing is in order of total references used in the three years. Years given are those of the reviews, not those in which the original articles appeared. Table 2 shows the percentages of the total references originating from * Northam Warren Corporation, Stamford, Conn., U.S.A.
