PREFACE - This comprehensive, modem encyclopedia of surfactant products hasbeen compiled with the cooperation of the major national and internationalsurfactant manufacturers in order to give the user quick and thoroughinformation on each tradename product that is included. Informationfrom thousands of brochures, technical bulletins, and data sheets has beengleaned in order to make a complete profile on each surfactant productavailable from one source-this three volume compendium. Though sometimeslimited by the information provided by the manufacturers, in mostinstances, the chemical ingredients, properties, form, applications, etc. ofeach 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, thisreference work will be able to serve as a useful tool to the many chemicalengineers and salespeople here and abroad.We want to extend our thanks to Roberta Dakan for her dedication andtireless efforts in helping make this encyclopedia as accurate and consistentas possible.When the temperature at which properties such as viscosity, density,surface tension; solubilities, etc. is not included, a standard temperature of25 C is to be assumed. The information in this publication is reliable tothe best of our knowledge. We would be glad to be informed of any errorsor omissions so that these can be integrated into subsequent editions ofthis encyclopedia.
