    PREFACE - This encyclopedia is an attempt to coordinate and unify practical information on plastic, polymer, and resin trademark products. These categories overlap, i.e., plastics are a subset of polymers, and resins are often, but not always, polymers. However, it has been our aim to give the user of this compilation fingertip availability to a large quantity of essential information about these products. This three-volume compendium has been made possible through the cooperation of the major national and international plastic, polymer, and resin manufacturers. The information provided here has been gleaned from thousands of brochures, technical bulletins, and data sheets, but the extent of the information provided for each product has been limited by the amount of data given to us by the manufacturers. Whenever possible and/or appropriate, we have given the chemical description, applications, form and color, general, mechanical, thermal, and electrical properties of each product. With the state of technological growth in these industries constantly increasing, this encyclopedia should serve as an important tool for chemists, engineers, and salespeople here and abroad. We want to extend our thanks to Roberta Dakan for her tireless efforts in helping make this encyclopedia as accurate and consistent as possible. It should be noted that when the temperatures of properties such as viscosity, density, solubility, etc. are not included, a standard temperature of 25 C is to be assumed. The information in this publication is reliable to the best of our knowledge. We would appreciate being informed of any errors or omissions so that these can be integrated into subsequent editions of this encyclopedia.

    PREFACE - This comprehensive, modem encyclopedia of surfactant products has been compiled with the cooperation of the major national and international surfactant manufacturers in order to give the user quick and thorough information on each tradename product that is included. Information from thousands of brochures, technical bulletins, and data sheets has been gleaned in order to make a complete profile on each surfactant product available from one source-this three volume compendium. Though sometimes limited by the information provided by the manufacturers, in most instances, the chemical ingredients, properties, form, applications, etc. of each product are discussed in detail. The use of surfactants pervades almost every chemical industrial concern- including textiles, paints, pesticides, foods, cosmetics, pharamceuticals, etc. We hope that because of the universality of surfactants, this reference work will be able to serve as a useful tool to the many chemical engineers and salespeople here and abroad. We want to extend our thanks to Roberta Dakan for her dedication and tireless efforts in helping make this encyclopedia as accurate and consistent as possible. When the temperature at which properties such as viscosity, density, surface tension; solubilities, etc. is not included, a standard temperature of 25 C is to be assumed. The information in this publication is reliable to the best of our knowledge. We would be glad to be informed of any errors or omissions so that these can be integrated into subsequent editions of this encyclopedia.

    Who is the master confectioner? He is the man who is an expert in his trade, who knows his business from A to Z, and can teach others to become proficient in this field. The author of this book began as a candymaker in early youth and has devoted his entire life to candymaking. He has written this book so that others may benefit from fifty-two years of experience and hard work. Many good candy books have been published, but as a rule they do not cover the retail and smaller wholesale manufacturing field completely. For example: A certain formula, though it may be the best, calls for steam or vacuum cooking. This will not suit the candymaker who uses open-fire cooking. Here is only one example in a hundred where a formula that is suitable for the large candy factory will not give good results in the medium shop. The large candy manufacturer has his highly paid executive to take care of all his problems, but the smaller manufacturer has his hands full with making and selling his products. He is only too likely to neglect the candymaking end. That is why this book should be of particular interest to the retail and medium-wholesale candymaker. The man who must know his business from A to Z should find this work a treasury of candymaking.

    There is hardly a technical library in the world in which the volumes of the Chemical Formulary (Volumes 1-34) do not occupy a prominent place. Chemists both experienced and beginner, continually refer to them. It does not duplicate any of the formulas included in previous volumes, but lists a wide array of modern and salable products from all branches of the chemical industries. An excellent reference for formulation problems. -CONTENTS - I. Introduction - II. Adhesives - III. Coatings - IV. Cosmetics - V. Detergents and Disinfectants - VI. Drug Products - VII. Elastomers, Plastics and Resins - VIII. Foods and Beverages - IX. Polishes - X. Textile Specialties - XI. Miscellaneous - Appendix - Index - PREFACE - Chemistry, as taught in our schools and colleges, concerns chiefly synthesis, analysis, and engineering-and properly so. It is part of the right foundation for the education of the chemist. Many a chemist entering an Industry soon finds that most of the products manufactured by his concern are not synthetic or definite complex compounds, but are mixtures, blends, or highly complex compounds of which he knows little or nothing. The literature in this field, if any, may be meager, scattered, or obsolete. Even chemists with years of experience In one or more Industries spend considerable time and effort in acquainting themselves with any new field which they may enter. Consulting chemists similarly have to solve problems brought to them from industries foreign to them. There was a definite need for an up-to-date compilation of formulae for chemical compounding and treatment. Since the fields to be covered are many and varied, an editorial board of chemists and engineers engaged in many industries was formed. Many publications, laboratories, manufacturing firms, and Individuals have been consulted to obtain the latest and best information. It is felt that the formulas given in this volume will save chemists and allied workers much time and effort. Manufacturers and sellers of chemicals will find, In these formulae, new uses for their products. Non-chemical executives, professional men, and Interested laymen will make through this volume a "speaking acquaintance" with products which they may be using, trying or selling. It often happens that two Individuals using the same Ingredients in the same formula get different results. This may be due to slight deviations in the raw materials or unfamiliarity with the intricacies of a new technique. Accordingly, repeated experiments may be necessary to get the best results. Although many of the formulas given are being used commercially, many have been taken from the literature and may be subject to various errors and omissions. This should be taken into consideration. Wherever possible, it is advisable to consult with other chemists or technical workers regarding commercial production.

    CONTENTS - Resins - Tradename Products and Generic Equivalents - Generic Chemical Synonyms and Cross References - Tradename Product Manufacturers - PREFACE - This compendium serves a unique function for those involved in the chemical industry-it provides the necessary information for making the decision as to which trademark chemical product is most suitable for a particular application. The chemicals included in this second book of the series have their major function as dispersants, solvents, and solubilizers, however, complete cross-referencing is provided for the multiple functions of all the chemicals. The first section which is the major portion of each volume contains the most common generic name of the chemicals as the main entry. All these generic entries are in alphabetical order. Synonyms for these chemicals are then listed. The CTFA name appears alongside the appropriate generic name. The structural and/or molecular formula of the chemical is listed whenever possible. The generic chemical is sold under various tradenames and these are listed here in alphabetical order for ease of reference along with their manufacturer in parentheses. The Category subheading lists all the possible functions that the chemical can serve. Because of differences in form, activity, etc., individual tradenames of the generic chemical are used in particular applications more frequently. These are delineated in the Applications section. The differences in properties. toxicity/handling. storage/handling, and standard packaging are specified in the subsequent sections wherever distinguishing characteristics are known. The second section of the volume TRADENAME PRODUCTS AND GENERIC EQUN ALENTS helps the user who only knows a chemical by one tradename to locate its main entry in section 1. The user can look up this tradename in this section of the book and be referred to the appropriate, main-entry, generic chemical name. The third section GENERIC CHEMICAL SYNONYMS AND CROSS REFERENCES provides a way of locating the main entries by knowing only one of the synonyms. If the generic chemical is not in the volume, it will refer you to the volume in which it is contained. The fourth section TRADENAME PRODUCT MANUFACTURERS lists the full addresses of the companies that manufacture or distribute the tradename products found in the first section.
