| Hazard Information | Back Directory | [Chemical Properties]
Clear colorless to pale yellowish liquid. | [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). |
| Safety Data | Back Directory | [Toxicity]
Both the acute oral LD50 value in rats and the acute dermal LD50 value in rabbits exceeded 5 g/kg (Moreno, 1975). |
| Questions And Answer | Back Directory | [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. |
