Other names :
Natural Rhodinol ; 3,7-dimethyloct-6-en-1-ol and 3,7-dimethyloct-7-en-1-ol ; 3,7-dimethyl-6 & 7-octen-1-ol
Volatility :
Heart
Uses in perfumery :
Rhodinol 70® is used in rose, geranium, raspberry and honey notes. Useful in fougere and all other perfumes around the rose.
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.
Year of discovery :
Discovered in 1891.
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.

Synthesis route :
Rhodinol 70® is not synthesized, but it is extracted from geranium essential oil by fractional distillation.
Synthesis precursor :
Rhodinol 70® is not a precursor to the synthesis of another compound of olfactory interest.
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.

- Comments :
- Crude gums of Liquidambar styraficula L. var. macrophylla or Liquidambar orientalis Mill. should not be used as fragrance ingredients for any finished product application. Only extracts or distillates (resinoids, absolutes and oils), prepared from exudations of Liquidambar styraciflua L. var. macrophylla or Liquidambar orientalis Mill., can be used. Styrax oil can be obtained from solvent extraction or pyrolysis. Styrax oil obtained through pyrolysis shall be rectified according to Good Manufacturing Practices (GMP) and the content of Polycyclic Aromatic Hydrocarbons (PAH) resulting from their use shall respect the following requirement: Benzopyrene and 1,2-Benzanthracene are to be used as markers for PAH. If used alone or in combination with rectified Cade oil, rectified Birch tar oils or rectified Opoponax oil, the total concentration of both of the markers should not exceed 1 ppb in the final product.
