Ethyl Butyrate
The 'Juicy Fruit' Molecule
Fruity Pineapple, Banana, Juicy Fruit, Tutti Frutti, Cognac, Powerful
About this material
Ethyl Butyrate (also known as Ethyl Butanoate) is an ester formed from ethanol and Butyric Acid.
Ethyl Butyrate can be found in the odours of several different fruits, though distinctively pineapple in character.
Naturally present in Strawberry, Mango, Orange Juice and Grapefruit.
Ethyl Butyrate is both powerful and extremely diffusive. Too much however will evoke a vomit like odour, but will add a lift and freshness to floral and oriental fragrances in smaller amounts.
This ester has occasionally been used in minute traces in perfume compositions for its warm fruity effect in Rose and other floral bases.
It is also used as a masking agent for industrial fragrances.

This molecular reference matches the catalogue’s recorded CAS and formula. It does not confirm the supplied grade, purity, stereochemistry, isomer proportions, composition, impurities or unlisted constituents.
Fragrance allergen reference
Generic regulatory reference only. This is not a supplier allergen declaration, measured composition, allergen-free claim or finished-product labelling assessment.
Raw-material reference based on recorded CAS numbers. A CAS match identifies a reference entry; it does not verify the supplied grade, composition, purity or finished-product compliance. Naturals, bases and mixtures require composition review.

No direct listed-entry CAS match in this jurisdiction’s held reference set. This does not mean the material is allergen-free. Constituents, grouped entries and natural-material composition may require further review.
Finished-cosmetic declaration thresholds: greater than 0.001% leave-on; greater than 0.01% rinse-off. Apply the current target-market rules to the actual complete formulation; no concentration is inferred here.

Creative ideas to explore
Creative directions, not tested formulas.Fruit with its peel
With citrus and leafy contrastsExplore a fruit sketch that includes a suggestion of peel or leaf. Compare those accents separately against the fruity reference, noticing whether they create a fresher impression or pull the idea away from the fruit you imagined.
An orchard in bloom
With rose or another familiar flowerPlace the fruity direction beside a simple floral accord. Keep a flower-only comparison and assess whether the fruit reads as a supporting accent, a juicy centre or a separate note that needs a different setting.
Fruit and cream
With vanilla and soft wood directionsSketch a more rounded fruit idea with vanilla as one variation and soft wood as another. Compare sweetness and texture before combining both, leaving room for the original fruity character to remain identifiable in the study.
