JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 503 the HLB values generally brings about the maximization of solubilization power and high emulsion stability. The book is divided into five main chapters. First, the authors discuss the re- lationships that exist between the solution behavior of surfactants, solubilization of hydrocarbons, and the formation of mi- croemulsions. The second chapter dis- cusses, at some depth, the hydrophile-li- pophile balance (HLB). The authors com- pare the various systems that have been devised for measuring HLB values and make the important point, often over- looked, that temperature and salt concen- trations are important factors that can greatly affect HLB values. This chapter also contains a valuable compilation of HLB values of many commercial surfac- rants. Finally, the authors outline some practical examples for the use of the HLB concept in product formulation. The third chapter deals with the concept of Phase Inversion Temperature (PIT) of emul- sions. The authors believe PIT to be one of the most important quantities that characterize emulsions. Therefore, they describe at considerable length the various factors which can influence the PIT values, (e.g., lengths of hydrocarbon chain and oxyethylene chain, salt concen- tration, pH, etc.). Chapter 5 discusses the stability of emulsions. The authors de- scribe the various methods used for emul- sification (PIT method, emulsification by inversion, etc.) and also point out that the method of preparation, among other factors, has an important bearing on the subsequent stability of the resulting emulsion. Again, considerable scope is given to the discussion of other factors that affect emulsion stability. Emulsions and Solubilization is a valuable contribution to the literature. The au- thors, who both have contributed greatly to our understanding of emulsions, give a very wide-ranging review of the present state of the science of emulsions. How- ever, this work is not a reference book rather, it should be regarded as an intro- ductory textbook for young scientists and chemists who are new to the field of for- mulation science and who wish to ac- quaint themselves with the basic prin- ciples of emulsion technology. The book suffers somewhat from lack of editorial at- tention. The language is often difficult and involved and does not lend itself to an easy reading there are a number of printing errors. Whereas the scientific data and facts given are far-reaching, it is not always straightforward to discern the implications of the data shown. The au- thors should have put more emphasis on giving interpretations and explanations rather than just presenting experimental findings. Too often, the reader is left to his own devices to find his way and to draw the right conclusions from the wealth'i-of experimental facts presented. This requires considerable time and thought and hinders the easy use of the book in helping to solve problems as they emerge during routine formulation work. In spite of some of these shortcomings, however, Shinoda and Friberg's book should become a valuable addition to cos- metic chemists' and product formulators' bookshelves--MIKLOS M.

Journal of the Society of Cosmetic Chemists INFORMATION FOR AUTHORS The JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS publishes papers concerned with cos- metics or the sciences underlying cosmetics, as well as other papers of interest to SCC members. It is the function of the Editorial Committee to set standards, to judge the scientific merit of a paper, and to help in the editing of the paper and its preparation for press. The Editorial Committee is charged with the responsibility for the maintainante of the JOURN^L'S high standards. It is therefore not the policy of the JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS tO guarantee publication of all submitted papers. All papers presented before a meeting or seminar of the SocIETY OF COSMETIC CHEMISTS or before one of its sections, or those papers submitted directly to the Editor will be considered for publication in the Journal. Papers presented before the SOCIETY OF COSMETIC CHEMISTS or one of its sections are the property of the SOCIETY and may not be published in or submitted to other journals. Only if the JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS is unable to publish a presented paper may it be published in another journal of the author's choice. SUBJECT MATTER The JOURN^L will consider manuscripts for publication in the following categories, provided they are prepared in proper scientific style and adequately referenced: 1. Original Articles. Descriptions of original research work in cosmetics or related areas. 2. General Articles. Articles of a general character may be considered for publication providing they are of a scientific and technical nature. These articles may be concerned with newer analytical techniques, developments in dermatology, toxicology, etc. 3. Review Articles. Intended to present an overview of recent advances in a specific area related to cosmetics. The author of such a review is expected to be actively engaged in the area and capable of presenting a critical evaluation of published reports of a scientific and technical nature. Solicited by special invitation from the Editor and Editorial Committee not subject to review by the Editorial Committee. 4. Preliminary Communications. Intended to provide for rapid dissemination of novel con- cepts and findings, such articles should not exceed four printed pages (approx. 10 double- spaced typed pages). Subject to review, but the time for editorial action will not exceed three weeks and the manuscripts will be published ahead of those submitted for regular processing. 5. Technical Notes. Relatively short manuscripts containing new information obtained by laboratory investigations, these do not contain the depth or extent of research involved in an Original Article. 6. Letters to the Editor. Comments on JOURN^L articles are invited, as well as brief contri- butions on any aspect of cosmetic or related science that does not warrant publication of a full-length paper in one of our other categories. May include figures and/or references, but brevity is necessary. 505
