Uses
Other comments :
It should not be confused with Rhodinol (without '70'), which is the other name of laevorotatory Citronellol.
It contains two of the 26 fragrance allergens: Geraniol and Citronellol.
Stability :
Terpenes tend to polymerize by oxydation
Uses in perfumery :
Rhodinol 70® is used in rose, geranium, raspberry and honey notes. Useful in fougere and all other perfumes around the rose.
Year of discovery :
Discovered in 1891.
Isomerism :
Geraniol and Nerol present in Rhodinol 70® are both diastereoisomers, while Citronellol is a positional isomer of these two molecules. Here, Citronellol is a lot more present under its laevorotatory than dextrorotatory form, which makes Rhodinol 70® slightly laevorotatory.
Synthesis precursor :
Rhodinol 70® is not a precursor to the synthesis of another compound of olfactory interest.
Natural availability :
Rhodinol 70® is a mixture of molecules that contains 62% Citronellol, 35% Geraniol and about 1% Nerol. It possesses the aspects of these three compounds in majority. It is not synthesized, but extracted from Geranium EO by fractional distillation. The fraction of Rhodinol 70® is collected because the three molecules that compose it have a similar volatility. Geraniol and Nerol are diastereoisomers, and Citronellol has a molar mass and a structure very close to these two compounds.
Synthesis route :
Rhodinol 70® is not synthesized, but it is extracted from geranium essential oil by fractional distillation.
