Safety Profile
USE WITH AWARENESSWhat Does Cinnamon Bark Oil Smell Like?
Cinnamon bark oil erupts with an intense, fiery sweetness – think red-hot candies melting on a stove. The top note is almost medicinal in its phenolic sharpness, like crushed cinnamon sticks in a mortar. As it evolves, the heart reveals a creamy vanillic undertone that softens the spice, while the base develops woody, slightly leathery facets. Dry-down leaves a warm, resinous glow reminiscent of antique wooden chests lined with spice pouches.

The cinnamon bark oil here amplifies the fragrance’s explosive opening, creating an addictive contrast with pink pepper and saffron. It’s used at a precisely calibrated dose to deliver recognizability without overwhelming.
Forms the spicy backbone of this 90s powerhouse, blending with honey and tobacco to create a sweet yet masculine trail. The cinnamon’s warmth prevents the composition from becoming cloying.
Chemistry, Properties & Perfumer Guide
The Chemistry
Cinnamon bark oil is primarily composed of cinnamaldehyde (60-80%), along with eugenol, linalool, and various terpenes. The oil is steam distilled from the inner bark of Cinnamomum zeylanicum trees. Cinnamaldehyde’s conjugated double bond system makes it highly reactive, contributing both to its intense aroma and potential sensitization properties. The oil’s exact composition varies based on geographic origin and distillation methods.

Safety, Regulatory & Sustainability
⚠ Regulatory Disclaimer
General reference only. IFRA, REACH, EU Cosmetics Regulation standards update periodically. Consult current IFRA Standards Library before formulating. Not legal or regulatory advice.
IFRA Status
IFRA restricted to 0.05% in leave-on products (Amendment 49) due to cinnamaldehyde sensitization potential.
EU Allergen Declaration
Must be declared when cinnamaldehyde exceeds 0.001% in leave-on or 0.01% in rinse-off products (Annex III No. 5).
GHS Classification
RIFM Assessment
RIFM assessment confirms skin sensitization risk at high concentrations but safe at IFRA-recommended levels.
Sustainability
Most cinnamon oil comes from Sri Lanka and Seychelles, where trees are grown in mixed agroforestry systems. Sustainable harvesting involves stripping bark without killing trees. Synthetic cinnamaldehyde offers a renewable alternative but lacks the oil’s complexity.
