2. Sensory Profile

Allyl amyl glycolate is renowned for its intense, fruity, and green aroma, reminiscent of pineapple with a hint of apple. It is often described as having a fresh, sweet, and slightly waxy character. The compound is used as an impact note in both flavor and fragrance formulations due to its potent and diffusive nature. The odor threshold is relatively low, allowing it to impart a noticeable effect even at minimal concentrations.

4. Use in Flavors

Allyl amyl glycolate is extensively used in flavor formulations, particularly in fruit flavors such as pineapple, apple, and pear. It serves as a key impact note, enhancing the authenticity and freshness of fruit profiles. Typical use levels in finished food products range from 0.1 to 5 ppm, with variations depending on the desired intensity and application. It is stable under typical food processing conditions but may degrade under extreme heat or acidic environments.

5. Use in Fragrances

In the fragrance industry, allyl amyl glycolate is valued for its ability to impart a fresh, fruity top note. It is commonly used in floral and fruity fragrance families, contributing to the overall brightness and appeal of the scent. Typical concentrations in fragrance formulations range from 0.1% to 1%, depending on the desired effect and product type. Its volatility makes it a prominent top note, providing an initial burst of freshness.

7. Toxicology, Safety & Exposure Considerations

• Oral Exposure: Allyl amyl glycolate is considered safe for use in food flavors at typical concentrations, with a high margin of safety.
• Dermal Exposure: Generally non-irritating and non-sensitizing at typical fragrance concentrations. IFRA guidelines should be consulted for specific product types.
• Inhalation Exposure: Low volatility reduces occupational exposure risks, but standard ventilation practices are recommended in manufacturing settings.

The risk profiles for food and fragrance applications are similar, with no significant safety concerns at typical use levels.

8. Practical Insights for Formulators

Allyl amyl glycolate is prized for its ability to enhance fruitiness and freshness in both flavors and fragrances. It synergizes well with other esters and fruity compounds, creating complex and appealing profiles. Formulators should be cautious of its potency, as overuse can lead to an overpowering effect. It is often under-utilized in non-fruit applications, where it can add unexpected brightness.

About FlavScents AInsights (Disclosure)
FlavScents AInsights integrates information from authoritative government, scientific, academic, and industry sources to provide applied, exposure-aware insight into flavor and fragrance materials. Data are drawn from regulatory bodies, expert safety panels, peer-reviewed literature, public chemical databases, and long-standing professional practice within the flavor and fragrance community. Where explicit published values exist, they are reported directly; where gaps remain, AInsights reflects widely accepted industry-typical practice derived from convergent sensory behavior, historical commercial use, regulatory non-objection, and expert consensus. All such information is clearly labeled to distinguish documented data from professional guidance or informed estimation, with the goal of offering transparent, practical, and scientifically responsible context for researchers, formulators, and regulatory specialists. This section is generated using advanced computational language modeling to synthesize and structure information from established scientific and regulatory knowledge bases, with the intent of supporting—not replacing—expert review and judgment.
