Neroli, bergamot

C10H13O. B.p. 225-226"C. A terpenic alcohol and a constituent of neroli, petit-grain and bergamot, and of many other essential oils. Nerol has a blander smell than its isomer, geraniol, and is more valuable as a constituent of perfumes. 

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. 

Heliotropin melts at 37°, but its perfume is injured by exposure to a temperature several degrees below this, and it should always be stored in cool dark places. In very hot weather the stock may with advantage be kept dissolved in alcohol, ready for use. Its perfume is a powerful heliotrope odour, and is improved by blending it with a little coumarin or vanillin, or with bergamot, lemon, or neroli oil. Attention should be drawn to the fact that the fancy perfumes whose names resemble heliotrope are usually mixtures of heliotropin—the cheaper ones being chiefly acetanilide, the more expensive ones containing vanillin or coumarin.

Linalyl acetate is the principal constituent of the essential oils of bergamot, clary sage, lavender and lavandin. It is also present in the essential oils of Salvia officinalis, petitgrain, sassafras, neroli, lemon, lime, a few Mentha species and others. 

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.

An interesting variability is observed in plants from Rutaceae family. In bergamot (Citrus auranthium Bergamia), neroli and petitgrain (Citrus auranhtium ssp. amara), and lime oils (Citrus aurantifolia) the prevalence of (-)-linalool has been found. In orange (Citrus sinensis) and tangerine (Citrus reticulata) (+)-linalool is the dominant enantiomer, while in lemon (Citrus limon) and grapefruit (Citrus paradisi) the enantiomeric ratio of linalool is close to racemate [31,40]. 

The note is neroli and bergamot- and cinnamon-like (Winter et al., 1975a), peculiar odor, gassy-green, remotely reminiscent of geranium, but overall mild and rather nondescript, choking in high concentration, Sometimes described as metallic odor (Arctander, 1967).
