Cinnamon oil

Химические свойства

Cassia oil (Chinese cinnamon oil) is obtained by steam distillation of the leaves, twigs, and bark of Cinnamomum aromaticum Nees (Cinnamomum cassia Blume, Lauraceae) mainly growing in China. It is a reddish-brown liquid with a sweet–spicy, cinnamon-like odor.
d²⁰₂₀ 1.052–1.070; n²⁰_D 1.6000–1.6140; solubility: 1 vol in 3 vol of 70% ethanol at 20 ℃; acid number: max. 15; content of carbonyl compounds (calculated as cinnamaldehyde): min. 80%.
In contrast to cinnamon bark oil, cassia oil contains a considerable amount of 2-methoxycinnamaldehyde (3–15%) in addition to its main constituent, cinnamaldehyde (70–88%). Cassia oil is used predominantly in flavoring soft drinks (cola-type). Annually ≥600 t are produced in China, smaller quantities in Vietnam.

Физические свойства

It is a yellow liquid and soluble in most fixed oils and propylene glycol. It is insoluble in glycerin and in mineral oil.

Вхождение

Found in the bark of the shrub Cinnamomum zeylanicum Nees (Fam: Laura-ceae). Cinnamon oil is mainly extracted from the bark and leaves of the many species of the genus Cinnamomum of the Laurel family (Lauraceae), which is widely distributed throughout the tropical and subtropical Asia, and from waste products formed during the preparation of cinnamon spice. However, Cinnamomum zeylanicum, native to Sri Lanka, is the chief source of cinnamon spice and oil worldwide.

Использование

cinnamon oil (Cinnamomum zeylanicum) is said to have a stimulating effect on the skin. It can also be used for fragrance. Widely recognized for its tonic and antiseptic properties, cinnamon oil is very important in traditional pharmacopoeia. Cinnamon oil is used in a wide variety of skin care and make-up preparations. It is obtained from distillation of the plant’s leaves. It can cause irritation if used in high doses.

Подготовка

By steam distillation of the dried inner bark of the shrub C. zeylanicum Nees (Guenther. 1950).
Steam distillation is the simplest method to extract the essential oil from cinnamon. Steam distillation is mostly used to extract various types of essential oils. The process is cheaper than other extraction methods. It does not require any solvent and is safer than other methods.

Cостав эфирных масел

The chief constituent of cinnamon bark oil is cinnamic aldehyde

Профиль безопасности

Poison by skin contact. Moderately toxic by ingestion and intraperitoneal routes. A human skin irritant. Mutation data reported. See also CINNAMALDEHYDE and ALDEHYDES. When heated to decomposition it emits acrid smoke and irritating fumes.

Метаболизм

Cinnamic aldehyde, the chief constituent of cinnamon bark oil, is oxidized to cinnamic acid, which is then degraded to benzoic acid (Williams, 1959). Additional published data
