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; n20D 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.
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.
cinnamon bark oil has similar properties to those of cinnamon oil, but this distillation of the plant’s bark is considered of much higher quality than extractions from the plant’s leaves. use in high doses or in high concentrations could produce skin irritations.
