Helichrysum italicum essential oil in glass vial. Several species are grown as ornamental plants, and for dried flowers. When cut young and dried, the open flowers and stalks preserve their colour and shape for long periods.
There are three primary types of plant oil, differing both the means of extracting the relevant parts of the plant, and in the nature of the resulting oil: Vegetable fats and oils were historically extracted by putting part of the plant under pressure, squeezing out the oil. Macerated oils consist of a base oil to which parts of plants are added.
The essential oil of this plant, which contains the chemical compound geraniol, is valued for its scent and for traditional medicinal and household uses. Palmarosa oil may be an effective insect repellent when applied to stored grain and beans, [ 5 ] an antihelmintic against nematodes , [ 6 ] and an antifungal and mosquito repellent. [ 7 ]
The remaining waxy mass is known as a concrete, which is a mixture of essential oil, waxes, resins, and other lipophilic (oil-soluble) plant material, since these solvents effectively remove all hydrophobic compounds in the raw material. The solvent is then removed by a lower temperature distillation process and reclaimed for re-use.
Patchouli (also spelled patchouly or pachouli) (/ p ə ˈ tʃ uː l i /; Pogostemon cablin) is a species of flowering plant in the family Lamiaceae, commonly called the mint or deadnettle family. The plant grows as a bushy perennial herb, with erect stems reaching up to 75 centimetres (30 in) in height and bearing small, pale, pink-white flowers.
The flower is a vital ingredient in Kewra and is used in special-occasion dishes in South Asia, particularly those associated with Muslim communities. [2] Kewra flowers have a sweet, perfumed odour with a pleasant quality similar to rose flowers, but kewra is more fruity. The aqueous distillate (kewra water, pandanus flower water) is quite diluted.
The essential oil of the flower is obtained through steam distillation of the flowers and separated into different grades (extra, 1, 2, or 3) according to when the distillates are obtained. The main aromatic components of ylang-ylang oil are benzyl acetate, linalool, p-cresyl methyl ether, and methyl benzoate, responsible for its characteristic ...
Orris concrete melts when it reaches around body temperature. It has a woody, fatty-oily, yet distinctly violet-like odor: sweet floral, warm & tenacious with a fruity undertone. Orris concrete is used in perfumery when the presence of myristic acid is not prohibitive, e.g.: in soap perfumes where the weak acid only acts as a fixative.
