Cedryl Acetate (CAS 77-54-3) — Woody Heart Note Fragrance Ingredient
Cedryl Acetate
CAS 77-54-3
What Is Cedryl Acetate?
Cedryl acetate is a woody fragrance ingredient commonly found in perfumes, colognes, and home fragrances. It adds a warm, cedar-like character to scents. This synthetic molecule mimics natural cedarwood notes but with enhanced stability and longevity in formulations.
Safety Profile
GENERALLY SAFEWhat Does Cedryl Acetate Smell Like?
Cedryl acetate delivers a rich, woody aroma reminiscent of aged cedar chests with subtle amber undertones. The scent evolves from an initial crisp woodiness to a smoother, slightly sweet dry-down that lingers close to the skin. Compared to raw cedarwood oils, it offers superior tenacity and a more refined olfactory profile without the harsh edges.
Scent Profile
In Famous Fragrances
Fragrance associations may not reflect actual formulations.
Provides the foundational woody character that blends with vetiver and citrus notes. Its stability allows the fragrance to maintain woody depth throughout wear.
Used alongside sandalwood to create a dry, pencil-shaving cedar effect that defines this minimalist woody composition.

Chemistry, Properties & Perfumer Guide
The Chemistry
Cedryl acetate is a sesquiterpene derivative synthesized through acetylation of cedrol, a major component of cedarwood oil. The acetate group increases volatility compared to cedrol while maintaining woody characteristics. Industrial production typically involves fractional distillation of cedarwood oil followed by chemical modification.
