1. Basic Info
Name: Cassia oil
Alias: Cinnamon bark oil, Ceylon cinnamon oil, Oleum Cinnamomi, FEMA 2291
CAS No.: 8015-91-6
Composition: Natural mixed essential oil (complex mixture, no single fixed molecular formula)
Main active ingredient: Cinnamaldehyde (C9H8O, Molecular Weight:132.16)
Extraction source: Steam distillation of dried inner bark of
Cinnamomum zeylanicum (Lauraceae)
2. Physical & Chemical Properties
Physical Properties
- Appearance: Light yellow to deep amber transparent oily liquid
- Odor: Strong warm sweet spicy cinnamon aroma, slightly burning spicy taste
- Solubility: Miscible with ethanol, propylene glycol, vegetable oils; soluble in 3 volumes of 70% ethanol; insoluble in glycerin and pure water
- Density (20℃): 1.010–1.030 g/cm3
- Boiling Range: 194–234 ℃
- Refractive Index nD2?: 1.5730–1.5910
- Optical Rotation [α]???: -2° ~ 0°
- Closed-cup Flash Point: 57 ℃
- Vapor Pressure: 15.72 Pa at 25 ℃
- Hygroscopy: Non-hygroscopic; volatile with obvious fragrance diffusivity
Chemical Properties
- Main components: Cinnamaldehyde 55%–78%, eugenol, cinnamyl acetate, limonene, p-cymene, pinene etc.
- Aldehyde reactivity: Cinnamaldehyde undergoes oxidation, aldol condensation, reduction, esterification; long-term air exposure oxidizes to cinnamic acid, darkening oil color
- Antibacterial & antifungal activity: Inhibits mold, yeast and food spoilage bacteria, natural preservative characteristic
- Acid-base stability: Stable under neutral/weak acid; strong alkali triggers aldehyde polymerization; concentrated acid causes decomposition
- Thermal stability: Stable below 160℃; high-temperature heating releases irritating smoke and volatile decomposition products
- Photostability: Light-sensitive; UV irradiation accelerates oxidation and color deepening
- Compatibility: Compatible with most flavor solvents, cosmetic base oils; incompatible with strong oxidants, concentrated strong alkali
3. Main Application Fields
1. Food Flavor Industry (Core Application)
Permitted food flavor per GB 2760 & FCC standard
- Bakery, candy, chewing gum, chocolate, beverage, wine spice blending
- Spicy seasoning, toothpaste, oral care flavor base; tobacco flavor modifier
2. Daily Fragrance & Cosmetics

- Oral medicine flavoring agent to mask bitter taste; natural antibacterial preservative for herbal extracts
- Raw material for isolating high-purity cinnamaldehyde, intermediate for synthetic cinnamyl alcohol, cinnamate spices
4. Natural Food Preservative
Fruit postharvest fresh-keeping agent, inhibit mold growth; antisepsis additive for sauce, pickled food
5. Organic Synthesis Intermediate
Separate cinnamaldehyde monomer as raw material for fine spices, pharmaceutical intermediates, polymer additives
