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.
