Book Description
During the past decade there have been many changes in the perfumery industry which are not so much due to the discovery and application of new raw materials, but rather to the astronomic increase in the cost of labour required to produce them. This is reflected more particularly in the flower industry, where the cost of collecting the blossoms delivered to the factories has gone up year after year, so much so that most flowers with the possible exception of Mimosa, have reached a cost price which has compelled the perfumer to either reduce his purchases of absolutes and concretes, or alternatively to substitute them from a cheaper source, or even to discontinue their use. This development raises an important and almost insoluble problem for the perfumer, who is faced with the necessity of trying to keep unchanged the bouquet of his fragrances, and moreover, to ensure no loss of strength and diffusiveness. Of course, this problem applies more especially to the adjustment of formulae for established perfumes, because in every new creation the present high cost of raw materials receives imperative con sideration before the formula is approved.

Book Description
This classic work by Poucher, first published in 1923, was last produced in three volumes titled, respectively The Raw Materials of Perfumery (seventh edition, 1974), The Production, Manufacture and Application of Perfumes (eighth edition, 1974) and Modern Cosmetics (eighth edition, 1974). Its popularity is well demonstrated by there having been three reprints of these editions in 1976, 1979 and 1984, res pecti vel y . The history of events can be traced by reference to the prefaces to earlier editions and those interested should study these with care since they give a fascinating insight into developments in the subject fields covered by Poucher's Perfumes, Cosmetics and Soaps over the years. It is not proposed to provide a resume here. In this Volume I, the current edition attempts to provide data about raw materials in a more formalized way than before, so that not only the history of some compounds can be checked, but also so that useful reference information can be obtained. It is particularly relevant to do this, since it is not always easy to be certain of nomenclature. Moreover, as we move towards 'ingredient labelling' (a trend not welcomed by some), a high level of uniformity will be needed. Whether this will come from adoption of CTFA terminology, use of CAS numbers or some other system is not clear. Where possible, such data have been included so that readers may identify materials more readily. Where given, CAS numbers are located in the top right-hand corner of each entry.
