Preface -



Historically, this book was started about 40 years ago. At that time, the

cosmetic, drug and flavor industries were seeking substitutes for glycerin

and ethyl alcohol-for economic reasons and to avoid the red tape connected

with the buying, storage, use, and selling of alcohol and alcoholic

products. Fair substitutes were developed for both of these products, but

when the price of glycerin was stabilized at a reasonable figure, these substitutes

were almost completely forgotten.





Over a period of years, this writer has developed substitutes or alternatives

for numerous products in diverse industrial fields. Thus, a file of such

materials has been built up. To this has been added the suggestions of

others and references from scientific and technical journals and texts.





This book cannot be regarded as complete or encyclopediac. The subject

matter is in a state of flux and is growing and changing continuously. It

should be useful to many as a starting point. It should not be expected

to give the final answer to a highly specialized need. It is the task of the

specialist or expert to glean from it what may be applicable and to interpret,

interpolate, or imagineer a solution to his specific problem.





Condensation, rather than elaboration, has been the precept in assembling

this information, in order to expedite the publication of this book. It is

the concentrated essence of many years of experience of many chemists,

engineers, and other technical workers.
