Cedrol (CAS 77-53-2) — Woody Base Note Fragrance Ingredient
Cedrol
CAS 77-53-2
What Is Cedrol?
Cedrol is a naturally occurring alcohol found in cedarwood oil, giving it that distinctive woody aroma. You’ll encounter it in men’s colognes, home fragrances, and natural insect repellents. As a key component of cedar’s scent profile, cedrol provides longevity and depth to woody accords, making it invaluable for creating forest-like or pencil-shaving freshness in perfumery.
Safety Profile
GENERALLY SAFE
What Does Cedrol Smell Like?
Cedrol opens with a sharp, pencil-like woodiness reminiscent of freshly sharpened cedar pencils. As it evolves, the scent becomes creamier, revealing subtle camphoraceous undertones and a clean, almost laundry-like dryness. The dry-down is remarkably persistent – like the lingering scent of a well-used cedar chest, blending warm wood resins with a faintly medicinal edge that prevents it from becoming overly sweet.

Chemistry, Properties & Perfumer Guide
The Chemistry
Cedrol is a sesquiterpene alcohol with the molecular formula C15H26O. It occurs naturally in several Juniperus and Cupressus species. Industrially, it’s typically isolated from Texas cedarwood oil via fractional distillation. The molecule has three chiral centers, with the (+)-enantiomer being more common in nature and possessing a stronger odor profile. Commercial production sometimes involves hydrogenation of cedrene derivatives.
