How does cinnamon bark oil compare with cinnamon leaf oil and Ceylon cinnamon oil?
Cinnamon bark oil (Cinnamomum cassia) is often confused with two similar but distinctly different oils: cinnamon leaf oil and Ceylon (true) cinnamon oil. They differ in source, chemistry, aroma, safety and price.
Comparison Table
| Aspect | Cassia bark oil (this product) | Ceylon bark oil | Cinnamon leaf oil |
|---|---|---|---|
| Botanical | Cinnamomum cassia (Chinese) | Cinnamomum verum (Sri Lanka) | Cinnamomum spp. leaves |
| Main constituent | trans-Cinnamaldehyde 70-88% | trans-Cinnamaldehyde ~50-75% | Eugenol 70-90% |
| Aroma | Hot, sweet, powerful, spicy | Sweet, delicate, spicy-floral | Harsh, clove-like, phenolic |
| Coumarin | ≤0.1% (regulated) | High (1-8%) | Low/absent |
| Skin sensitivity | High (strong sensitizer) | High | Moderate (eugenol) |
| Price | Low-moderate (commodity) | High (2-4x cassia) | Lowest |
| Typical use | Food, fragrance, candles, pharma | Fine perfumery, food | Clove-type fragrance, soaps |
- If your application needs the iconic 'cinnamon candy/bakery' sweetness, cassia bark oil is the classic and most economical choice
- Ceylon bark oil is softer and more delicate, preferred in fine perfumery, but much more expensive and higher in coumarin (a bigger IFRA burden)
- Cinnamon leaf oil smells more like clove than cinnamon and is cheaper; it is not a substitute for bark oil in food where 'cinnamon' flavor is specified
- EU food labeling distinguishes 'cinnamon' (C. verum) from 'cassia' (C. cassia); German BfR recommends limiting cassia/coumarin intake — follow your local labeling rules
