Ethyl linalool Chemical Properties,Usage,Production

Aroma

Floral, only slightly woody-green, soft odor of moderate tenacity. The odor type compared to Linalool indicates that "Ethyl Iinalool" is softer, more waxy, less volatile, less woodygrecn and overall more floral. It is more Coriander-like, less Bois-de-Rose-like.

Uses in Perfume

Ethyl linalool has been suggested for use in perfume compositions as a modifier for LinaIool with certain advantages over that marerial. Ethyl Iinalool has a somewhat slower rate of evaporation and is easier to work with, needs only normal fixation, and blends with more materials. It introduces softer, more floralwoody, less citrusy notes, according to the composition in which it is used. Along with Ethyl Iinalyl acetate, it forms a pleasant Bergamot-type background note even in soap perfumes, a combination which is more stable than Bergamot oil itself.
The alcohol is also an interesting item in Muguet, Lilac, Lily, Appleblossom, etc. as well as in fantasy creations.

Physical properties

Colorless slightly oily liquid. Very slightly soluble in Mater, soluble in alcohol and oils.

Occurrence

Has apparently not been reported to occur in nature.

Uses

Ethyl Linalool is fresh bois de rose herbal wet green lavender bergamot. It has a floral, fresh, bergamot character and is sweeter and less agrestic than Linalool. As with Linalool, it is used in a wide variety of notes for floral bouquets.

Preparation

From methyl ethyl ketone and acetylene through a series of reactions (Bedoukian, 1967).

Metabolism

Tertiary alcohols are not readily metabolized and may be excreted in the urine both unchanged and highly conjugated with glucuronic acid. In rabbits, carbon-carbon double bonds make little difference to the extent of conjugation of terf-hexyl alcohols (Williams, 1959).
