Cinnamon Bark Absolute is an extract, made using a supercritical fluid extraction process. Cinnamon oil is a clear mobile liquid, light to dark amber in colour, with a characteristic spice like odour, derived from the leaves and bark of Cinnamomum zeylanicum Blume / Cinnamomum verum [also referred to as the Sri Lanka / Ceylon type] of the Lauraceae family.

The main active ingredient(s) in a typical oil sample are phenols (minimum 70%) namely: Eugenol (70 â?? 83%), trans Cinnamic aldehyde (1 - 1.5%), trans Cinnamyl acetate (1.1 - 1.8%), Eugenyl acetate (1 - 3%), and Benzyl benzoate (2 -4%). However, the chemical composition may defer between the oil extracts from leaves compared from that from the bark.
