化学的特性
Rose oil is obtained by steam distillation of blossoms of Rosa x damascena Mill.,which is mainly cultivated in Turkey, Bulgaria (Kazanlik rose), and Iran. Since a reasonable amount of rose oil is still dissolved in the aqueous phase after steam distillation, the distillation water (rose water) is redistilled or extracted.Rose oil is a yellow partly crystallized liquid with the characteristic odor of rose blossoms and distinct tea and honey notes. d2020 0.848–0.880; n20D 1.4520–1.4700; α20D 5 ° to 1.8 °; fp +16–23.5 ℃; ester value: 7–24; content by GC (Bulgaria/Turkey/Morocco): citronellol: 20–34/34–49/30–47%; geraniol 15–22/8–20/6–23%; nerol 5–12/3–11/3–11%; phenylethyl alcohol <3.5/<3/<3%.
The major constituents of rose oil are ()-citronellol, geraniol, and nerol. In contrast to the absolute, the oil contains only a minor amount of phenylethyl alcohol, which is most soluble in water.
物理的性質
Rose absolute is a reddish liquid. The physical–chemical constants of extracts and distillates are strongly dependent on the type of material used for extraction.天然物の起源
Found in the flowers of Rosa centifolia L. (Fam. Rosaceae) (Guenther, 1952).使用
rose oil has been credited with anti-septic, disinfectant, slightly tonic, and soothing properties. Some sources also cite moisturizing and moisture-retention abilities. It is found helpful in cases of skin redness or inflammation, and where moisturization and regeneration is needed. Rose oil may be beneficial to all skin types, particularly mature, dry, or sensitive skins. As one of the most expensive essential oils, true rose oil is only used in very high-grade perfumes. Rose oil is almost always adulterated with substances like geranium, lemongrass, palmarosa, and terpene alcohols. However, the process of adulteration has become so refined that it is almost impossible to discover frauds. To produce rose oil, rose buds are picked for only a few hours in the morning, right after the dew, and are immediately distilled. According to some sources, 30 roses are required to make one drop of oil. It is considered the least toxic of all essences. given the cost and potential of adulteration, rosewater is widely used as a replacement for rose oil in cosmetics and perfumery. Among its rose oil’s many constituents are citronellol, geraniol, nerol, linalool, farnesol, and eugenol.製造方法
By steam distillation of the flowers of Rosa centifolia L. (Gildemeister & Hoffman, 1959; Naves, 1974).精油の成分
Although rose oil is a very complicated mixture of over 100 different components, the major compound recovered from the blossom is phenylethyl alcohol. The other main components are the rose alcohols geraniol, citronellol and nerol. Several other components are present in very small amounts, but are very important for the overall quality of the oil. For example, the compound damascenone, an important odor constituent, is present in a relatively minor amount.安全性プロファイル
Moderately toxic by skin contact. Mildly toxic by ingestion. When heated to decomposition it emits acrid smoke and irritating fumes参考文献
