Allyl Cyclohexyl Propionate
Chinese name: 菠萝酯
English name: Allyl Cyclohexyl Propionate
Chemical name: Allyl Cyclohexylpropionate
CAS No.: 2705-87-5
FEMA：2026
Key Characteristics
The most prominent feature of allyl cyclohexyl propionate is its exceptionally realistic and intense pineapple-flesh aroma. It immediately evokes ripe, juicy pineapple with a sweet–tart balance, making it a cornerstone ingredient in pineapple-type flavors.
As a high-impact aroma chemical, it is extremely powerful and diffusive; even low levels provide a noticeable effect.
This is a major drawback of allyl cyclohexyl propionate. Due to its allyl functionality, it is relatively unstable in chemical nature and prone to hydrolysis and oxidation, especially under alkaline or oxygen-rich conditions, causing weakening or degradation of its aroma. It therefore requires airtight, light-protected, and low-temperature storage and should be used promptly.
It functions primarily as a fresh top-note booster, offering an immediate tropical-fruit burst with limited persistence.
Primary Applications
Beverages: Widely used in pineapple-flavored sodas, juices, fruit teas, and sports drinks.
Confectionery: Used in hard candies, gummies, chewing gum, jellies, etc.
Bakery: Applied in cookies, cakes, ice cream, and pastries.
Dairy: Used in yogurt and puddings.
Alcoholic beverages: Used to craft tropical profiles in premixed drinks and liqueurs.
Cosmetics & Personal Care：Creates a sweet, pleasant tropical-fruit atmosphere when used in shampoos, shower gels, hand creams, and lip glosses, especially popular in summer season products.
Household cleaning products: Impart a clean, refreshing fruity scent in dishwashing liquids, hand soaps, and air fresheners.
Usage Recommendations and Precautions
Dosage: Extremely low dosage is sufficient. In finished consumer products, the concentration is typically at the ppm level. In fragrance compositions, even as a primary character material, 0.1%–2% is usually adequate; excessive use may lead to harsh chemical nuances or off-notes.
Safety: It has been evaluated by FEMA (Flavor and Extract Manufacturers Association of the United States) and the FDA (U.S. Food and Drug Administration) and is approved for safe use in foods (FEMA GRAS: 2026). In daily-use fragrances, IFRA imposes no specific restriction, though its potential allergenicity should be considered and safe concentrations maintained.
Storage: Allyl cyclohexyl propionate must be kept sealed, protected from light, and stored in a cool place to maximize stability and freshness.
Compatibility:
- Blending with other fruity flavors: Creates complex tropical fruit profiles or pina colada accords when combined with isoamyl acetate (banana), strawberry aldehyde, and coconut aldehyde.
- Blending with alcoholic notes: Enhances tropical cocktail character when paired with rum ether and related materials.
- Precautions: Avoid mixing with alkaline substances to prevent accelerated decomposition.
