Description
Refer to GERANIUM.
Chemical Properties
Palmarosa oil is obtained by steam distillation of wild or cultivated Cymbopogonmartinii
(Roxb.) J.F.Wats., collected when in blossom. It is a pale yellow
liquid with a characteristic rose-like odor and a grassy note.
d2020 0.880–0.894; n20D 1.4710–1.4780; α20D +1.4 ° to +3 °; solubility: 1 vol in
2 vol of 70% ethanol at 20 ℃; ester number (after acetylation): 255–280, corresponding
to a total alcohol content of 80–95%, free alcohol content (calculated
as geraniol): 72–94%. High-grade palmarosa oil may contain up to
95% geraniol and its esters; it is produced in smaller quantities
than other oils obtained from aromatic grasses (～100 t/yr mainly in India).
Palmarosa oil is the starting material for geraniol and geranyl esters of high
odor quality, but it is also used for perfuming soaps and cosmetics.
Chemical Properties
Palmarosa oil is steam-distilled or water-distilled mainly from wild-growing, fresh or dried grass of the plant Cymbopogan martinii, varietas motia Palmarosa oil has a sweet, foral rosy odor and various backnotes or topnotes according to the quality and age of the oil Palmarosa oil blends well with all the conventional soap perfume materials, and it forms an excellent base with small amounts of geranium oil and oakmoss concrete or absolute Commonly referred to as East Indian geranium oil, it is frequently used to adulterate rose oil due to this oil’s high concentration of geraniol and citronellol.
Chemical Properties
The oil is obtained by steam distillation of partially dried plants (Cymbopgon martinii) harvested during September
and October. It has a rose-like odor and a characteristic, herbaceous undertone.
Physical properties
It is a light-yellow to yellow oil that is often hazy and brownish. It is soluble in most fixed oils
and propylene glycol. It is soluble in mineral oil with turbidity and opalescence. It is practically insoluble in glycerin.
Occurrence
Found in the grass of Cymbopogon martini Stapf, var Motia (Fam. Graminae).
Definition

Preparation
By steam distillation of the partially dried grass Cymbopogon martini Stapf, var. Motia.
Essential oil composition
