JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 383 4. Abbreviations. Any abbreviation that will not be immediately understood by a non-expert reader should be defined in parentheses following its first appearance in the text. In most cases, both clipped words and acronyms are unpunctuated. Chemical names and formulae, especially where they may be handwritten, should be unambiguously clear to the editor. Some prefixes before names of organic compounds must be italicized, e.g., cis-, p-, tert-, etc. Consult the list of commonly-used abbreviations in the ACS Handbook. 5. Trade Names. A trade name must be followed by the sign "©." All common cosmetic ingredients should be referred to by their GENERIC names, as indicated in the latest edition of CTFA Cosmetic Ingredient Dictionary, The United States Pharmacopeia (U.S.P.) and the National Formulary (N.F.). Manufacturer's designation may be included in parentheses. If a material is not listed, then the proprietary or trademarked name can be used, with the chemical composition and name and address of the manufacturer given in parentheses or footnote. 6. Structural Formulae. Structural formulae should be used only if absolutely necessary and if the chemical in question is not known to the reader. They should be numbered and referred to in the text by Arabic numerals. 7. Tables. Tables should be numbered consecutively, using Roman numerals. Appropriate captions should also be included. 8. Figures. Photographs, drawings and graphs are numbered consecutively in the text using Arabic numerals, e.g., (Figure 3). On the back of each, the figure number, title of paper, author's name, and the top of the figure should be indicated in pencil. Captions should be typed double-spaced on a separate sheet of paper. Drawings should be prepared on plain white drawing stock or vellum, using India ink or standard tapes. Their size should not exceed 210 mm x 297 mm (81/4" x 11"). Original copies are strongly preferred, but glossy photographic reproductions are acceptable. All numbers and letters must be approximately the same size on any individual figure, and of sufficient size to be legible after reduction to print size. All lettering except the caption should be considered part of the drawing and drawn in. TYPEWRITTEN LETTERING IS NOT ACCEPTABLE BECAUSE TYPING DOES NOT FORM THE CLEAN, SHARP LETTERING NEEDED FOR GOOD REPRODUCTION. Axis labeling on graphs should be read from the bottom or right-hand side and must be of sufficient size. Authors must pay special attention to the quality of computer-generated graphs. The com- puter-driven printer should be set to give lines of sufficient density for reproduction. In many cases, the axes must be drawn in by hand. If computer-formed labeling on the plot is of poor quality, an illustrator should superimpose acceptable characters on the sheet. Color photographs, where they are essential to the content of the paper, may be acceptable at the Editor's discretion, and usually at extra cost to the author. Consult the Editor first. If the author desires the return of original figures, he or she should so specify when he submits the manuscript. Figures will be held for 6 months following publication of the paper and then returned by mail. 9. References. References should be numbered in the order in which they appear in the text and should be listed in numerical order at the end of the article under "References." Citations in the text should be on line and parenthesized, e.g., (6) or (11-13). The references to journal articles must appear in the following form: (a) The first name, followed by initials and surname of each author. (b) The full title of the paper (first word capitalized).

384 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS (c) The name of the journal in italics, i.e., underlined once in the typewritten manuscript. Use standard abbreviations as in Chemical Abstracts. (d) The volume number in bold face type, i.e. underlined in the manuscript with a wavy line. (e) The first and last pages of the article separated by a hyphen. (f) Year of publication of the article (in parentheses) the month must be included for journals which do not use continuous pagination. The following is an example of a correctly prepared journal reference note all spacing and punctuation: (1) L. E. Gaul and G. B. Underwood, Relation of dew point and barometric pressure to chapping of normal skin, J. Invest. Dermatol., 19, 9-19 (July 1952). Book references are handled similarly and should include pertinent page numbers: (16) S. Rothman, Physiology and Biochemistry of the Skin (The University of Chicago Press, Chicago, 1954), pp. 494-560. References to books containing contributions from authors appear as follows: (4) S. D. Gershon, M. A. Goldberg, and M. M. Rieger, "Permanent Waving," in Cos- metics, Science and Technology, 2nd ed., M. S. Balsam and E. Sagarin, Eds. (Wiley- Interscience, New York, 1972), Vol. 2, pp. 167-250. AFTER SUBMISSION OF MANUSCRIPTS Rejection of Papers Submitted: Manuscripts not prepared in accordance with these directions or deemed to be outside the scope of articles published in the Journal will be returned to the author by the Editor. Galley Proofs: After an author's paper is accepted and before final publication, galley proofs will be sent to the senior author for careful review and correction. Proofs should be verified against the manuscript. The Publication Committee does not accept this responsibility. Alter- ations in an article after it is typeset are made at the author's expense, and the author will be billed for such changes. Corrected galley proofs must be returned within 10 days to the Journal office. Offprints and Reprints: The senior author of each paper will automatically receive 50 offprints free of charge, following publication of his paper. Additional offprints, or the more expensive stitched reprints, must be ordered at the time the galley proofs are returned and will be billed to the author. An order blank for this purpose is included with the galley proofs when it is sent to the author--return it with the galley. Page Charges: The authors of a manuscript published in the JOURN^L will be assessed a page charge of $35.00 per printed page. Any material set into type but ordered deleted from pub- lication at the galley proof stage must also be paid for by the author. These charges will be invoiced to the senior author at the time of publication.
