THE ESSENTIAL OILS Vol. I

---

The industry and science of essential oils have undergone within the last two decades more changes than could have been anticipated by those writers who, during the 1920's, contributed so valuably to our knowledge of this field. It is, therefore, no derogation of the works of Gildemeister and Hoffmann, Parry, Finnemore, and others, to state that the time is past due for bringing the whole subject up-to-date. This is the author's motive for the present treatise on the production, chemistry, analysis and appli- cation of these interesting and important products. It seems particularly fitting that this work be published in the United States, which, as the largest user of essential oils, has the most vital concern in the progress and ex- pansion of the essential oil industry.

Within the last ten years and largely as a result of World War II-

there have taken place fundamental developments within the field, especially

with respect to new sources of supply in the Western Hemisphere. It has

been the author's rare privilege to witness most of these developments at

first hand. His travels for more than twenty years have taken him the

length and breadth of Europe, through Africa, Asia, Australia, into the new

producing centers of North, Central and South America in all of which

places he surveyed the production of essential oils at their source. The original purpose of this systematic survey was to supply Fritzsche Brothers, Inc., of New York, the essential oil industry in general, and Gov- ernment agencies with exhaustive data on the production of essential oils. In the course of this work the author collected countless samples of authen- tic oils, produced under his supervision and of guaranteed purity. These were shipped to his headquarters in New York and submitted to careful analysis, which permitted the establishment of certain criteria of purity for many hitherto dubious oils. The results of such work have appeared in a series of articles published in leading trade journals during the last twenty years, for the information and guidance of those engaged in the production and in the use of these materials.

As the work progressed, the author was repeatedly urged to publish his data in their entirety, so that they might be readily accessible in compre- hensive and up-to-date form. He has at last, therefore, attempted to com- bine in this work his own observations in the field, the seventy-five years' experience of Fritzsche Brothers, Inc., as producers, investigators and dis- tributors of essential oils, and the data resulting from more than one hundred
