Aroma chemicals are isolates, or chemically treated oils or components of oils. Some components are removed physically, others chemically. In most cases, they are further purified by distillation. For example, Bois de Rose (rosewood) oil may be distilled to isolate linalool, which may be then further treated chemically to yield derivatives such as linalyl acetate, an important fragrance ingredient and a primary component in its own right of lavender and lavandin oils. Vetiver oil Haiti, although containing only 70% alcohols, is treated with acetic anhydride, then carefully distilled to include valuable odor components in the distillate, even though they may not be esters. 

Citrus Family. This is a popular fragrance group noted for its refreshing brisk quaUty. Lemon, lime, orange, and bergamot are important ingredients. These oils combine well with lavender and amber accords. 

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. 

I ve found that if I bring in coffee beans, put them in a little cup, and snort it, I can clear my sinuses and nasal passages. I also carry lavender with me because lavender clears the air. If there s a smell that s hard for me, I smell the coffee beans or put a little lavender on my temples to try to change the air. And I tell people that we have a fragrance-free policy. 

A fragrance company in Japan conducted tests in an attempt to determine the effects of smell on people. They pumped different fragrances into an area where a number of keyboard entry operators were stationed and monitored the frequency of mistakes the workers made. The results showed that pleasant odors like jasmine and lavender were associated with significant reductions in errors. 

Dynamic extractions of the organic flavonr and fragrance componnds from dried lavender flowers and rosemary leaves nsing SCCO2 were carried ont. The data from the lavender and rosemary extractions were fitted to a model to prodnce the characteristic extraction cnrve. Using data obtained from rosemary extractions, an extrapolation method derived from the model was used with data from shorter extractions to show that the model provided qnantitative analytical information (Walker et al., 1994). 

Uses. Linalool is used frequently in perfumery for fruity notes and for many flowery fragrance compositions (lily of the valley, lavender, and neroli). Because of its relatively high volatility, it imparts naturalness to top notes. Since linalool is stable in alkali, it can be used in soaps and detergents. Linalyl esters can be prepared from linalool. Most of the manufactured linalool is used in the production of vitamin E. 

Uses. Linalyl acetate is used extensively in perfumery. It is an excellent fragrance material for, among others, bergamot, lilac, lavender, linden, neroli, ylang-ylang, and phantasy notes (particularly chypre). Smaller amounts are used in other citrus products. Since linalyl acetate is fairly stable toward alkali, it can also be employed in soaps and detergents. 

C12H22O2, Mr 198.30, Z PlOl.SkPa 240 °C, d 0.8901, Wp 1.4515, occurs in many essential oils either as one of its optical isomers or as the racemate. The odor of racemic citronellyl acetate differs little from that of the optical isomers. ( )-Citronellyl acetate is a liquid with a fresh-fruity rose odor. It is often used as a fragrance, for example, for rose, lavender, and geranium notes as well as for eau de cologne with citrus nuances. Since it is relatively stable to alkali, it can be used in soaps and detergents. Citrus flavors acquire speciflc character through the addition of citronellyl acetate it is also used to round off other fruit flavors. 

Thymol is used as a dry top note in lavender compositions, in men s fragrances, and as a disinfectant in oral care products. It is also important as a starting material for the production of racemic menthol. 

Although lavender oil is more valuable than lavandin oil as a fragrance raw material, lavandin plants are more commonly cultivated because they give a higher yield of oil (ca. 50-100 kg/ha) and are hardier than lavender plants. 

Coumarin is a natural product occurring in the essential oils of a large number of plants, such as cinnamon, cassia, lavender and woodruff. It is used for its fragrance in many personal care products (perfumes, deodorants, soaps) and in tobacco, in household and industrial products to mask unpleasant odours and, in some countries, as a flavouring agent in food and beverages. It has also been used to treat several medical conditions. Exposure to coumarin may occur from its production, its natural presence in many plants and essential oils, and its several industrial, medical and consumer uses. 

A technique known as contingent negative variation (CNV) measures brain-wave reaction to olfaction. These types of studies have shown the eftect of materials such as lavender and nutmeg in reducing stress or anxiety, and the ability of oils such as peppermint to stimulate brainwave activity. CNV research was incorporated into the development of the fragrance for a consumer personal care product launched in the late 1980s. 

Several SM have been used by mankind for thousands of years22,27 as dyes (e.g., indigo, shikonine), flavors (e.g., vanillin, capsaicin, mustard oils), fragrances (e.g., rose oil, lavender oil and other essential oils), stimulants (e.g., caffeine, nicotine, ephedrine), hallucinogens (e.g., morphine, cocaine, mescaline, hyoscyamine, scopolamine, tetrahydrocannabinol), insecticides (e.g., nicotine, piperine, pyrethrin), vertebrate and human poisons (e.g., coniine, strychnine, aconitine) and even therapeutic agents (e.g., atropine, quinine, cardenolides, codeine, etc.). 

Distantly related plants, such as rose, jasmin, and lavender have quite independently gone down this road of complexity, based on different groups of chemical constituents. We may conclude, therefore, that complexity of odor has evolved as being the most effective way of evoking a desired response from an animal with the ability to smell and the ability to memorize odor. What is remarkable is that the particular combinations of materials that individual flowers produce to make up their fragrance have, to our own sense of smell, an identity far greater than a random mixture of as many ill-assorted chemicals. Perhaps we may infer from this, in view of the similarity of our receptor cells, that the balance of materials is as important to the olfactory mechanism of the bee as it is to our own in producing a sense of identity and aesthetic pleasure. 

Lavandin is produced by a hybrid plant Lavandula intermedia or Lavandula hybrida, which was bred by crossing the true lavender (Lavandula angustifolia) with spike lavender (Lavandula latifolia). Lavandin is sometimes called bastard lavender. Hybrids are widespread in horticulture, where they are bred to produce plants with the desired properties of the parents. The lavandin plants are easier to grow at lower altitudes (400-600 metres), yielding almost twice as much oil as the true lavender plant. Again, this is economically favourable and lavandin essential oil is particularly useful for the cosmetic and fragrance industries. 

Citral is an example of a very large group of natural products called terpenes. They are responsible for the characteristic odors of plants such as eucalyptus, pine, mint, peppermint, and lemon. The odors of camphor, menthol, lavender, rose, and hundreds of other fragrances are due to terpenes, which have ten carbon atoms with double bonds, and aldehyde, ketone, or alcohol functional groups.
