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. |
| 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. |
| Preparation | By steam distillation of the partially dried grass Cymbopogon martini Stapf, var. Motia. |
| Definition | Extractives and their physically modified derivatives. Cymbopogon martini, Gramineae. |
| Essential oil composition | The main constituent of palmarosa oil is geraniol |
| Safety Profile | Low toxicity by ingestion and skin contact. A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes |
