Safety Profile
USE WITH AWARENESSWhat Does Cinnamon bark oil, Laos Smell Like?
Laotian cinnamon bark oil erupts with an intense, fiery sweetness – like red-hot candies melting on a wooden spoon. The top notes are all sharp, peppery warmth with a hint of citrusy lift. As it settles, the heart reveals a velvety depth reminiscent of baked apples dusted with clove. The dry-down lingers as a resinous, slightly smoky base that clings to fabrics for days. Unlike softer cassia, this oil maintains a dry, almost leathery character beneath its sweetness, with a faint medicinal edge that adds intriguing complexity.
In Famous Fragrances
Fragrance associations may not reflect actual formulations.
The Laos cinnamon provides the explosive opening, tempered with citrus to prevent overwhelming sweetness. Its dry character balances the vanilla base, creating a modern masculine gourmand.
Used sparingly here to accentuate the clove and patchouli, adding a polished warmth without dominating the oriental floral composition.
Chemistry, Properties & Perfumer Guide
The Chemistry
Laotian cinnamon bark oil primarily contains cinnamaldehyde (60-80%), with eugenol, linalool, and coumarin derivatives. The unique terroir produces higher methoxycinnamaldehyde content than other regional variants. Steam distillation preserves the delicate ester compounds that give this oil its fruity undertones. Gas chromatography reveals trace amounts of safrole, naturally occurring but regulated in international commerce.
