Cyclohexaneethyl acetate (CAS 21722-83-8) — Sweet Top Note Fragrance Ingredient
Cyclohexaneethyl acetate
CAS 21722-83-8
What Is Cyclohexaneethyl acetate?
Cyclohexaneethyl acetate is a synthetic fragrance ingredient used to add fresh, fruity notes to perfumes and scented products. You’ll encounter it in body sprays, fabric softeners, and some citrus-forward fragrances. This molecule matters because it provides cost-effective fruity-floral character without using natural extracts, making fragrances more sustainable while maintaining pleasant scent profiles.
Safety Profile
GENERALLY SAFEWhat Does Cyclohexaneethyl acetate Smell Like?
Cyclohexaneethyl acetate opens with a crisp, pear-like fruitiness reminiscent of juicy Bartlett pears dipped in citrus zest. The heart develops into a soft floralcy with hints of lily-of-the-valley and a subtle green apple freshness. As it dries down, it leaves a clean musk-tinged trail with whisper-thin woody undertones. The overall effect is like biting into a perfectly ripe pear while standing in a sunlit orchard – bright yet comforting, with excellent diffusion that makes it useful for functional fragrances.
In Famous Fragrances
Fragrance associations may not reflect actual formulations.
Used as the primary fruity note to create a photorealistic pear accord, blending with hedione for diffusion and ambroxan for longevity.
Provides the crisp top note in this functional fragrance, combining with calone for a dewy fruit effect in laundry products.
Chemistry, Properties & Perfumer Guide
The Chemistry
Cyclohexaneethyl acetate belongs to the ester class of fragrance compounds, synthesized through esterification of cyclohexaneethanol with acetic acid. While not found in nature, its structure mimics fruity esters found in pears and apples. The synthesis typically employs acid catalysis under controlled conditions to prevent unwanted side reactions. The cyclohexane ring provides stability while the ethyl acetate moiety delivers the characteristic fruity odor.
