Allyl Cyclohexylpropionate

What Allyl Cyclohexylpropionate smells like

Allyl cyclohexylpropionate gives a powerful, sweet pineapple that the published descriptions consistently call smoother and rounder than the other allyl esters. Arctander describes it as powerful and sweet-fruity, smoother and sweeter than allyl caproate, with a fruitiness he likens to that of linalyl acetate. Supplier descriptions add a floral-herbaceous nuance recalling chamomile blossom, and some note a waxy, green-apple side. It is also unusually persistent for a fruity ester: suppliers report it lasting for days on a blotter, although their figures vary widely, so it carries pineapple well beyond the opening.

What makes Allyl Cyclohexylpropionate distinctive

Its smoothness and its staying power. Allyl caproate is fatty and rum-like and fades within the hour; allyl cyclohexylpropionate is sweeter and rounder and lingers, which is why it is treated as a mainstay of pineapple accords rather than a fleeting top note. A faint chamomile-like herbal facet, reported for allyl heptanoate too, is the other point of recognition.

Concentration and dilution

Strong enough that it is commonly handled as a dilution in dipropylene glycol for accurate dosing. The sources consulted do not describe its character changing with dilution.

Where the descriptions disagree: Suppliers' blotter-life figures differ widely, from about two days to over ten; all agree it is long-lasting for a fruity ester.

How Allyl Cyclohexylpropionate is used

Used to build the body of pineapple and tropical accords and to give fruity florals and fruity chypres a sweet, fruity lift. Because it lasts far longer than the light fruit esters, it can carry a pineapple impression into the heart of a fragrance, where allyl caproate or ethyl butyrate gives only the opening.

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

How Allyl Cyclohexylpropionate differs from similar materials

Allyl Caproate*

Arctander judged allyl cyclohexylpropionate smoother and sweeter. Allyl caproate is fattier, with a rum-like nuance, and fades far sooner. (compared directly by a cited source)

Allyl Heptanoate

Both carry a chamomile-like nuance in supplier descriptions. Allyl heptanoate adds banana and a waxy, slightly fermented ripeness; allyl cyclohexylpropionate is the smoother, purer pineapple.

Allyl Phenoxyacetate

Allyl phenoxyacetate shares the chamomile facet but leads with honey and a green, galbanum-like edge; allyl cyclohexylpropionate is the cleaner pineapple.

An asterisk marks a difference that a cited source states directly. The others compare the published descriptions of each material. 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 Standards covering Allyl Cyclohexylpropionate:

• "Allyl 3-cyclohexylpropionate" — type not stated in the library listing, 51st Amendment, published 2023-06
• "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 (2,014 reports): H302 harmful if swallowed (99.9% of reports); H312 harmful in contact with skin (98% of reports); H332 harmful if inhaled (84% of reports); H410 very toxic to aquatic life with long lasting effects (83.2% of reports); H317 may cause an allergic skin reaction (83% of reports); H400 very toxic to aquatic life (81.9% of reports); H315 causes skin irritation (13% of reports). A skin sensitiser classification concerns handling the neat material and the dose in a finished product; the IFRA Standards, where they apply, set the limits. Unless it is harmonised, this is the notifiers' own classification, not a binding one.
