following in parentheses. Abbreviations such as m/s, ml, rpm, and ug are used without periods. It is requested that authors avoid all unusual notations, e.g., milligram per cent (mg %) or ppm are better expressed as mg/100g or mg/kg. 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 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 International Cosmetic Ingredient Dictionary and Handbook (PCPC’s), 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: To publish the figures in your article with the highest quality, it is important to submit digital art that conforms to the appropriate resolution, size, color mode, and file format. Doing so will help to avoid delays in publication and maximize the quality of images. Photographs will be published in color at no additional cost to the author. Sizing and preparation: Submit figures at their final publication size do not scale figures. All panels of a multipart figure should be provided in the same file. If symbols are not explained on the face of the figure, only standard print characters may be used. Include figure titles in the legend and not on the figure itself. Labeling and Font Usage: Please use the same font for all figures in your paper, and use a standard font such as Arial, Helvetica, Times, Symbol, Mathematical Pi, and European Pi. Do not use varying letter type sizes within a single figure use the same size or similar sizes throughout. The preferred font size is 8 points the minimum font size is 6 points. Resolution and Raster Images: Low-resolution images are one of the leading causes of art resubmission and schedule delays. Submitted raster (i.e. pixel-based) images must meet the minimum resolution requirements: Monochrome (1-bit) images (line-art): Common examples are graphs and charts made of solid black and white, with no gray values. The suggested minimum resolution for this type of image is 1000 ppi at publication size. Combination Halftones: Common examples are color or grayscale figures containing halftone and line art elements. The suggested minimum resolution for this type of image is 600 ppi at publication size.

Halftones: Common examples are color or grayscale figures containing pictures only, with no text or thin lines. The suggested minimum resolution for this type of image is 300 ppi at publication size. Raster images should be supplied in TIF format. PDF and JPG are also acceptable. Vector Images: Vector images are typically generated using drawing or illustration programs (e.g., Adobe Illustrator) and are composed of mathematically defined geometric shapes—lines, objects, and fills. Vector graphics are resolution independent and can be enlarged to any size without quality loss. Vector images should be supplied in EPS format, with all fonts embedded or converted to outlines, and graph lines at least 0.25 points thick. PDF is also acceptable. Authors who do not comply with these guidelines will be asked to resubmit their figures in a print- quality format, which may delay publication. 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 initials and surname of each author. (b) The full title of the paper (first word capitalized). (c) The name of the journal in italics. Use standard abbreviations as in Chemical Abstracts. (d) The volume number in bold face type. (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 that 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 (1952). Book references are handled similarly and should include pertinent page numbers: 1) 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: 1) S. D. Gershon, M. A. Goldberg, and M. M. Rieger, "Permanent Waving," in Cosmetics, Science and Technology, 2nd ed., M. S. Balsam and E. Sagarin. Eds. (Wiley Interscience, New York, 1972), Vol. 2, pp. 167-250. 10. Claims of Priority/Primacy: The JOURNAL OF COSMETIC SCIENCE does not allow claims of priority or primacy therefore, terms such as “new”/“novel”/“first” should not be included in the title or body of the paper.
