Allyl Heptanoate

What Allyl Heptanoate smells like

Allyl heptanoate is a sweet, fruity pineapple ester whose descriptions lean riper and softer than allyl caproate's. Symrise describes it as strong and sweet-fruity, tending towards pineapple, with nuances reminiscent of chamomile and banana, and other suppliers repeat both the banana and the chamomile. Several note a waxy quality, one a ripe, slightly fermented edge, and Pell Wall Perfumes a cognac-like nuance. Beyond fruit accords, Arctander notes that it is also used in floral fragrance compositions.

What makes Allyl Heptanoate distinctive

The banana-and-chamomile pairing. Allyl caproate's secondary note is rum and allyl cyclohexylpropionate's a smooth sweetness; allyl heptanoate is the one whose pineapple is consistently described as edging towards ripe banana, with a herbal chamomile undertone and a waxy texture.

How Allyl Heptanoate is used

Used in pineapple, tropical and mixed-fruit accords, where its banana-tinged ripeness rounds out sharper esters, and — as Arctander notes — in floral compositions, where a trace brings fruit to a blossom note.

Typical role: modifier (used in small amounts to change the character of a blend).

How Allyl Heptanoate differs from similar materials

Allyl Caproate

Allyl caproate is fattier and rum-like; allyl heptanoate is described with banana, chamomile and a waxier texture instead.

Allyl Cyclohexylpropionate

Allyl cyclohexylpropionate is smoother and far longer-lasting. Allyl heptanoate shares its chamomile nuance but adds banana and a waxy, ripe, slightly fermented note.

Ethyl Hexanoate

Both pair pineapple with banana. Allyl heptanoate adds a chamomile-like herbal note; ethyl hexanoate a winey, estery one.

Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.

Formulation considerations

Allyl esters must meet IFRA's specification on free allyl alcohol. Check the Standard and your supplier's documents.

Safety and compliance

The IFRA Standards Library lists a Standard covering Allyl Heptanoate:

• "Allyl esters" — Specification, 44th Amendment, published 2009-01

Limits differ by product category and are set out in the Standard itself; this page does not reproduce them. The list above reflects the library as read on 19 October 2026.

Hazard classification of the neat substance, as PubChem summarises it, read 26 October 2026. Companies notifying the ECHA C&L Inventory classify it (2,608 reports): H302 harmful if swallowed (85.4% of reports); H311 toxic in contact with skin (79.9% of reports); H319 causes serious eye irritation (74.7% of reports); H410 very toxic to aquatic life with long lasting effects (69.1% of reports); H315 causes skin irritation (62.5% of reports); H400 very toxic to aquatic life (58.9% of reports); H373 may causes damage to organs through prolonged or repeated exposure (53.7% of reports); H312 harmful in contact with skin (20% of reports); H302+H312 harmful if swallowed or in contact with skin (17.1% of reports); H412 harmful to aquatic life with long lasting effects (15% of reports); H301 toxic if swallowed (14.6% of reports). Unless it is harmonised, this is the notifiers' own classification, not a binding one.
