3. Natural Occurrence & Formation

Amyl isoeugenol does not occur naturally in significant quantities and is primarily synthesized for use in flavor and fragrance applications. It is not typically associated with natural flavor or fragrance designations due to its synthetic origin.

The compound is synthesized through chemical processes that involve the modification of eugenol or isoeugenol, often involving alkylation reactions to introduce the amyl group.

4. Use in Flavors

Amyl isoeugenol is used in various flavor categories, including spice, floral, and woody profiles. It serves as a functional impact note, providing a clove-like aroma that enhances the complexity of flavor systems. Typical use levels in finished food or beverage products are not well-documented, but industry practice suggests usage in the range of 1-10 ppm, depending on the desired intensity and product type.

The compound is generally stable under typical food processing conditions, but formulators should consider its potential for oxidation, which can alter its sensory properties.

5. Use in Fragrances

In fragrance applications, amyl isoeugenol is utilized across various fragrance families, including oriental, spicy, and floral compositions. It acts as a modifier and impact note, contributing to the warm, spicy, and clove-like character of the fragrance. Typical concentration ranges in fragrance formulations are not explicitly documented, but it is often used at low levels due to its potent aroma.

Amyl isoeugenol is considered a middle note in fragrance compositions, providing a lasting aroma that bridges the transition from top to base notes.

7. Toxicology, Safety & Exposure Considerations

Amyl isoeugenol's safety profile is primarily evaluated through its potential exposure routes:

• Oral Exposure: Data on acceptable daily intake (ADI) or threshold of toxicological concern (TTC) is not clearly reported. Formulators should ensure usage levels are within industry-typical safe ranges.
• Dermal Exposure: The compound may cause irritation or sensitization in sensitive individuals. IFRA guidelines should be consulted for safe usage levels in fragrance applications.
• Inhalation Exposure: Due to its volatility, inhalation exposure should be minimized in occupational settings to prevent respiratory irritation.

Risk profiles may differ between food and fragrance applications, with dermal exposure being more relevant for fragrances.

8. Practical Insights for Formulators

Amyl isoeugenol is valued for its potent clove-like aroma, which can enhance both flavor and fragrance formulations. It synergizes well with other spicy and floral notes, providing depth and complexity. Common formulation pitfalls include overuse, leading to an overpowering aroma, and underuse, resulting in a lack of desired impact. Formulators should carefully balance its concentration to achieve the intended sensory profile.

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.
