Some oils consist almost entirely of esters for example, those of Oaultheria procumhens and Betula lenta contain about 99 per cent, of methyl salicylate. Bergamot and lavender owe the greater part of their perfume value to esters of linalol, of which the acetate predominates. Geranium oil owes its fragrance chiefly to geranyl esters, of which the tiglate is the chief. On the other hand, oils such as spike lavender, sandalwood, lemon-grass, and citronella contain but small quantities of esters, and owe their perfume value to entirely different types of compounds. 

The esters belonging to the geraniol series of alcohols are absolutely indispensable in the manufacture of artificial perfumes. When it is remembered that these esters are present in such oils as bergamot, rose, geranium, lavender, petit-grain, neroli, and numerous other sweetsmelling essential oils, it will readily be seen how useful they are in building up similar perfumes artificially. 

The Detection of Artificial Esters in Essential Oils.—The custom of valuing certain essential oils, such as lavender, bergamot, geranium, petit-grain, etc., by the determination of their ester-content, has led to the use of scientific adulterants in the form of artificial esters which have been deliberately employed for the purpose of misleading the analyst. Of course, the ester determination is not a true criterion of value, as most of this class of oUs owe their perfume value to various other bodies as well. The first compounds of this nature employed for adulteration were ethyl succinate and ethyl oxalate. For the detection of these in lavender oil the foUowing test was proposed by Guildemeister and Hoffman —... 

Naves, Y. R. Essential oil of zdravets (geranium macrorhirum L.). Perfum. 

It is a colorless liquid or a crystalline solid mp 26.8 °C) with an odor reminiscent of geranium leaves. Diphenyl ether is obtained as a byproduct in the production of phenol by high-pressure hydrolysis of chlorobenzene. Because of its stability and low price, diphenyl ether is used in large quantities in soap perfumes. However, its main application is as a heat-transfer medium (eutectic mixture with diphenyl).

Rose oxide is used in rose and geranium perfumes. 

Savon la Hose.—Rose soap is made from a mixture of olive oil soap, sixty pounds and curd soap, forty pounds colored with one pound of finely bolted vermilion. The perfume consisting of attars of rose, six ounces otters of santal and geranium, each one ounce and tincture of musk, eight ounces must be added to the cold soap in meal, and incorporated by kneading. The oil soap may be replaced by curd soap, but the quality of the rose soap will not then be so fine.

The alcohols occur in oil of rose and other flower essences. They have geranium or rose odors and are important perfume ingredients. The aldehydes have much stronger citruslike odors and occur as major or minor constituents in many essential oils, such as oil of citronella, oil of lemon, and so on. 

Diphenyl ether is used in the soap and perfume industries because of its great stability and strong geranium-type odor. 

Complicated mixtures may sometimes take on an identity which is no more difficult to recognize than a single chemical. Perfumes such as Anais Anais or Giorgio are as instantly recognizable as phenylethyl alcohol or anisaldehyde. Similarly lavender oil or geranium have a unique and memorable identity. Indeed, in our experience, students often can more easily identify these complicated mixtures than single chemical materials. Just why some perfumes have such strong identity is not fully understood, but, as will be discussed later, much of the skill of the perfumer lies in the ability to achieve such an identity in a composition. 

Even when smelling a complicated blend of materials experienced perfumers are readily able to recognize the presence of certain natural ingredients. They do not need to think of the hundreds of possible individual components each may contain. The specific combinations form an olfactory pattern that perfumers are immediately able to identify as, for instance, patchouli, geranium, or tolu balsam. 

While it is true that materials of identical chemical structure have the same odor qualities and are indistinguishable in their effect upon the skin irrespective of their origin, it is also true that very often synthetic and natural perfume materials that have the same name are not really identical in the chemical sense. Rhodinol from geranium oil consists of a different mixture of optical isomers than synthetic rhodinol. Eugenol from clove leaf oil is accompanied by different impurities than synthetic eugenol. Hence the natural and synthetic materials do differ in their odor quality, and they may differ in their effects upon the skin.

Note A classification of aromatic components of essential oils and perfumes. Top notes are sharp, penetrating and highly volatile (e.g. citrus oils, peppermint). Middle note characteristics are used to give body to blends (e.g. geranium, lavender). Base notes are the least volatile and used as fixatives to give more permanence (e.g. sandalwood, vetivert). 

Rose oxide is used in rose, geranium and all other floral fragrances. Its outstanding stability makes it suitable for use in perfume compositions for nearly all applications.
