Химические свойства

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; n²⁰_D 1.4710–1.4780; α²⁰_D +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.

Использование

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.
