Among a wealth of unusual products which are often produced only upon demand, we must include the alcohol extraction product of raw Linseed Oil. This kind of perfumery material represents the results of various perfumers study of natural flowers and their fragrance. In their intense search for notes with which they can duplicate certain of nature's fragrances, the perfumers often have to use materials other than the conventional flower extracts or straight synthetic chemicals. If a perfumer feels that there is a garlic like note in a rose base which he must duplicate, he will not hesitate to study the garlictype odors available in his laboratory or from a well furnished supply bouse: for example, absolute of asafoetida. Linseed Oil Absolute is obviously an example of just such a situation. When perfumers tried to duplicate the finer shades of lily, lilac, orangeflower, jasmin, tuberose, gardenia, etc., they found that the conventional amyl cinnamic aldehyde was not satisfactory. Modifications with hexyl cinnamic aldehyde, undecanolide, etc. did not solve the problem. Linseed Oil Absolute is a yellowish to light amber oily liquid of mild, fatty oily odor, reminiscent of the odor of freshly expressed linseed oil. The odor is also reminiscent of the slightly fishy animal like odor of fresh cod liver oil and of a refined oleic acid.
