π Odor Type β Floral, Rosy (metallic)
π Odor Strength β Weak
ππΌ Odor Profile β Decreasing: Hard green, very metallic note with an iron aspect. Slightly medicinal with a βdustyβ but more like iron note. it has partially the smell of dried blood (hence, iron) on the hands. Vegetable green, pea-like (Fulvio Ciccolo, Scentspiracy β 2022).
The official description for BRI: A rose, geranium odor with an earthy undertone.π Flavor Profile β Green, rosy, woody.
π Flavor Use β Green, rosy notes for a variety of fruits and berries, especially raspberry and blackberry. Use level (0,1 β 10 PPM)
βοΈ Use β Used in synthetic rose and geranium oils.
π Note β The odor of the Iaevo-isomer is sweeter, yet somewhat green. The odor of the dextro- isomer is more warm-spicy, sometimes gassy, and more often just herbaceous. Since Rose oxide is synthesized in quite different ways, the commercial products may contain by-products in various proportions.
What is Rose Oxide?
The name βRose oxideβ was originally applied to a formerly unknown material, isolated in 1959 from Bulgarian Rose oil which contained at least two stereo-isomerides of this formula.
The first synthetic ββRose oxideβ was a mixture of several isomers, and today many years later, a pure single isomer is still a rare material!
The preferred isomer of the molecule would be Cis-2-(2-Methyl-l-Propenyl)-4-methyltetrahydropyran.
Some differences between the Laevo and the Dextro isomers.
The dextro-cis and the dextro-trans forms are exclusively synthetic.
The laevo-cis and the Iaevo-trans forms may be either synthetic or natural.
