Hexyl isobutyrate opens with bright apple-pear sweetness but quickly reveals a distinctive winey, grape-like richness that sets it apart from simpler fruity esters. A ripe tropical warmth sits underneath. The dry-down stays sweet and clean with gentle peach undertones.
That winey quality makes it invaluable for grape and concord accords — territory most fruity esters cannot reach. In apple and pear compositions, it adds a riper, more complex dimension than hexyl butyrate alone. Tropical fruit blends gain depth and a fermented, juice-like naturalness.
Layer it with phenoxyethyl isobutyrate and citronellyl acetate for a convincing pear accord. In floral compositions, a trace adds overripe, almost boozy warmth — the kind of winey depth that separates flat fruit notes from convincing ones. It occurs naturally in apples, apricots, and chamomile.
Hexyl Isobutyrate vs Hexyl Butyrate
Both deliver apple-pear fruitiness, but hexyl butyrate is sweeter and waxier with clean pineapple undertones — straightforward orchard fruit. Hexyl isobutyrate trades some of that sweetness for a winey, grape-like richness and a drier, more tart edge.
Use hexyl butyrate for bright, uncomplicated apple-pear; use hexyl isobutyrate when you want that same fruit foundation with darker, more fermented depth. Blending the two gives you the best of both.

General Information
General Information
Like most suppliers and makers of quality raw materials for fragrances, we do not filter many of our products. This ensures that no odiferous matter is lost prior to use but can result in the appearance of small particles or slight clouding.
All alcoholic fragrances should be macerated for up to a month and then chilled in a moderate freezer overnight before being filtered fine. This will remove all cloudiness or detritus and is the industry norm.
