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
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.
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.
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).
Uses
rose geranium oil (Pelargonium graveolens) is a volatile oil used for masking odors and perfuming a product. Among rose geranium’s constituents are limonene, menthone, linalool, geranyl acetate, citronellol, and geraniol.
Uses
palmarosa oil (Cymbopogon martini) is attributed with soothing, moisturizing, anti-septic, tonic, and cell-regenerating properties. Palmarosa oil is said to have an immediate calming and refreshing effect on the skin. It is indicated for acne skin and dermatitis as well as for dry skin. This oil is widely used in perfumery and cosmetology because its fresh, rose-like scent makes it useful for the adulteration of rose oil, one of the most expensive essential oils. It can also be used to mask odors. Palmarosa oil is obtained by distillation of this flowering grasslike plant.
