Myrrh oil is used as a fragrance component or fixative in soaps, detergents, creams, lotions, and perfumes, with maximum use level of 0.8% reported in perfumes. The sweet, warm balsamic notes of absolute, oil, or res-inoidused in oriental spice fragrances, woody and forest notes often blended with geranium, musk, patchouli, and other heavy floral bases. ... 

Sandalwood Oil, East Indian. The use of sandalwood oil for its perfumery value is ancient, probably extending back some 4000 years. Oil from the powdered wood and roots of the tree Santalum album L. is produced primarily in India, under government control. Good quaUty oil is a pale yellow to yellow viscous Hquid characterized by an extremely soft, sweet—woody, almost ariimal—balsarnic odor. The extreme tenacity of the aroma makes it an ideal blender—fixative for woody-Oriental—floral fragrance bases. It also finds extensive use for the codistillation of other essential oils, such as rose, especially in India. There the so-called attars are made with sandalwood oil distilled over the flowers or by distillation of these flowers into sandalwood oil. The principal constituents of sandalwood oil are shown in Table 11 (37) and Figure 2. 

Amyris Oil. Obtained by steam distillation of the wood of y m hakamijera L., the so-called West Indian sandalwood which is indigenous to northern South America, Central America, and the West Indies, amyris oil [8015-65-4] is a pale yellow to brownish yellow viscous oil with a slightly oily-sweet and occasionally peppery balsamic woody note. It finds use as a blender and fixative for soap fragrances. The volatile constituents, which are primarily hydrocarbon and oxygenated sesquiterpenes, are shown in Table 22 and Figure 5 (63). 

Woody Family. The perfumer has available many different woody fragrance matetials, both natural and synthetic. Naturals such as sandal, vetivert, cedar, and patchouh often form the bases of these fragrances. They combine iu harmony with sweet notes, florals, and animal accords. 

Men s Fragrances. Earlier ia the twentieth century, men s fragrances were expected to have a masculine direction, such as tobacco, leather, fougere, or citms, even if only in name. This is no longer tme, however since the 1970s, men s perfumes have become less conservative and have allowed much more creative use of rich woody, ambery, and green notes. 

Acetylation of the alcohol mixture yields cedryl acetate [61789-42-2] (94) and a range of quaUties are available from manufacturers. Gedryl methyl ether [19870-74-7] is readily made and is useful in formulating woody-amber fragrances (188). 

In some cases, especially when the family is directed more toward Oriental fragrances, the use of vanillin can be up to 5%. These types of perfumes include Spanish fougnre, sweet or fmity chypres, woody Oriental, or spicy Oriental notes. AH the perfumes based on the sweet, warm, and powdery impressions brought by vanillin belong to the great family of the Oriental notes and of the amber notes. Vanillin, when used together with coumarin and nitro-musks, can have a concentration of up to 10%. 

The odors of single chemical compounds are extremely difficult to describe unequivocally. The odors of complex mixtures are often impossible to describe unless one of the components is so characteristic that it largely determines the odor or flavor of the composition. Although an objective classification is not possible, an odor can be described by adjectives such as flowery, fruity, woody, or hay-like, which relate the fragrances to natural or other known products with similar odors. 

Vetiveryl acetate is a light yellow liquid with a dry, fresh-woody odor. It is a popular fragrance mixture that is frequently used in luxury perfumery it is also used as a fixative in many fine fragrances. 

C13H26O, Mr 198.35, does not occur in nature. It is a clear, colorless to pale yellowish liquid, 0.910-0.915, Uq 1.472-1.475, with a woody, cedarlike odor. It can be prepared from dodecanol sodium by reaction with methyl halogenide. It is used as a stable wood fragrance in technical perfumery. 

C13H22O2, Mr 210.32 is a mixture of isomers, bpo kPa 102 °C, ng 1.4626, a colorless to pale yellow liquid with rosy, spicy, fruity, and woody odor. For its preparation 3,6-dimethyl-6-hepten-2-one and 7-methyl-6-octen-3-one are treated with ethyl diethylphosphoryl acetate to give a mixture of octadienoic acid esters. Cyclization with sulfuric/formic acid yields the title compounds as a mixture with isomers [134]. With its complex odor picture it is used in fine fragrances for shading. 

Veratraldehyde can be prepared by methylation of vanillin. It is used in oriental and warm-woody fragrances, as well as in flavor compositions for vanilla notes. It is an intermediate in, for example, the synthesis of pharmaceuticals. 

Cyclic ethers used as fragrances include a number of terpenoid compounds. Some of them, such as 1,4-cineole [470-67-7] and 1,8-cineole, occur in essential oils in significant quantities. Others are only minor components examples are rose oxide, nerol oxide [1786-08-9], and rose furan [15186-51-3], which contribute to the specific fragrance of rose oil. Caryophyllene oxide [1139-30-6], which has a woody,... 

Sesquiterpenic alcohols used in perfumery are mainly of natural origin. Three alcohols of this type are shown in Figure 8. Cedrol is the main alcohol constituent of cedarwood oil. Alpha-santalol constitutes about 80% of sandalwood oil and about 30% patchouli alcohol is found in patchouli oil, a very popular woody-earthy fragrance material. 

Otherwise, apart from the greater emphasis on floral notes, the general structure remains very similar to that of Fidji. A different combination of musks is used, including cyclopentadecanolide (4%), and cedryl acetate is incorporated into the woody complex. The woody notes are further emphasized by the use of an intensely powerful amber note—a "captive" material that is not generally available. Although the carnation-salicylate accord is again less than in L Air du Temps, it continues to play an important part in the overall fragrance. 

In Arpege (Lanvin 1927) the floral aspect of the fragrance was further developed by the use of compounded floral bases. Greater emphasis was also placed on the woody notes, including vetiveryl acetate, and on the animalic character, with a corresponding reduction in the vanillin and coumarin. 

Although lacking some of the impact required by today s standards, Calandre remains one of the most beautifully made perfumes. The combination of green, floral, and woody notes has made it the starting point for a number of successful fragrances used in toiletry and cosmetic products. 

The mellis accord, which makes up an important part of the fragrance here incorporates amyl salicylate in addition to benzyl salicylate, with the patchouli and woody aspect being accentuated, using cedryl acetate rather than the more traditional products derived from vetiver. Vertofix had yet to be discovered. The dominant spices, in combination with eugenol, are clove and cinnamon. 

Although we have described the perfumes in this family as being based on Hedione, in Coriandre the material used is Magnolione, a closely related material with a very similar though rather more jasminic olfactory character. This makes up some 20% of the formula with 10% of patchouli. Methyl ionone, vetiveryl acetate, cedryl acetate, Vertofix, and sandalwood make up the woody aspect of the fragrance, with a small amount of Galaxolide as the musk. 

The aldehyde 19 is described as a key molecule for the synthesis of different highly active fragrances like the saturated alcohol 1-(2,2,3,6-tetramethyl-l-cyclohexyl)-3-hexanole) 22 appreciated by perfumers because of its woody-/ambra-like character (22) according to Equation 15.2.8.
