2. Sensory Profile

Odor and Flavor Descriptors: cis-Homomenthyl acetate is known for its minty, fresh, and slightly fruity odor. It is often described as having a cooling effect, reminiscent of menthol but with a softer, more rounded profile.
Taste and/or Odor Thresholds: Specific thresholds are not clearly reported; however, it is typically used in low concentrations due to its potent sensory impact.
Typical Sensory Role: It serves as an impact note in formulations, providing a fresh and invigorating top note that enhances the overall sensory experience.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Known Natural Sources: cis-Homomenthyl acetate is not commonly found in nature and is primarily synthesized for use in flavor and fragrance applications.
Formation Pathways: It is typically produced through the esterification of homomenthol with acetic acid.
Relevance to “Natural Flavor” or “Natural Fragrance” Designation: Due to its synthetic origin, it does not qualify for natural flavor or fragrance designations unless derived from natural precursors.

4. Use in Flavors

Flavor Categories and Applications: Commonly used in mint and fruit flavor profiles, particularly in confectionery, chewing gum, and oral care products.
Functional Role in Flavor Systems: Acts as a cooling agent and flavor enhancer, providing a refreshing sensation.
Typical Use Levels: Documented use levels range from 1 to 10 ppm in finished products, with typical industry use around 5 ppm.
Stability Considerations: cis-Homomenthyl acetate is relatively stable under normal conditions but may degrade under high heat or acidic conditions.

6. Regulatory Status (Regional Overview)

United States (FDA / FEMA GRAS): Not explicitly listed as GRAS; usage should comply with general safety standards.
European Union (Reg. (EC) No 1334/2008): Not specifically listed; usage should align with general flavoring regulations.
United Kingdom: Follows EU regulations post-Brexit with no significant divergence reported.
Asia (Japan, China, ASEAN): Regulatory status not clearly reported; formulators should verify compliance with local regulations.
Latin America (e.g., Brazil, MERCOSUR): Specific regulatory status not documented; general safety and compliance with local standards are advised.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: No specific ADI or MSDI reported; usage should be guided by general safety assessments and industry standards.
Dermal Exposure: Generally considered safe for use in personal care products; however, formulators should assess for potential irritation or sensitization.
Inhalation Exposure: Volatility suggests potential for inhalation exposure; occupational safety measures should be considered in manufacturing settings.
Risk Profiles: No significant differences in risk profiles between food and fragrance applications have been reported.

8. Practical Insights for Formulators

Why This Material is Valuable: cis-Homomenthyl acetate is prized for its ability to impart a fresh, cooling sensation, enhancing both flavor and fragrance profiles.
Typical Synergies: Works well with other minty and fruity notes, enhancing the overall freshness and appeal.
Common Formulation Pitfalls: Overuse can lead to an overpowering minty note; careful balancing is required.
Situations Where It is Frequently Over- or Under-used: Often under-used in non-mint applications where a subtle cooling effect could enhance the product.

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.
