2. Sensory Profile

Cyclamen homoaldehyde is known for its floral and green odor profile, often described as reminiscent of cyclamen flowers. It exhibits moderate intensity and diffusion, making it suitable as a background note or modifier in complex formulations. The compound's odor threshold is not well-documented, but it is typically used in low concentrations due to its potent aroma.

In flavor applications, it can impart a subtle floral note, enhancing the overall complexity of the flavor profile without dominating it.

3. Natural Occurrence & Formation

Cyclamen homoaldehyde is not commonly found in nature and is primarily synthesized for use in the fragrance and flavor industries. Its formation is typically achieved through chemical synthesis rather than natural extraction, which limits its designation as a "natural flavor" or "natural fragrance" component.

The synthetic pathways often involve the manipulation of cyclohexene derivatives to introduce the aldehyde functional group, a process that can be controlled to yield high purity and consistency.

7. Toxicology, Safety & Exposure Considerations

Cyclamen homoaldehyde's safety profile is primarily assessed through its exposure routes:

• Oral Exposure: Data not found for specific ADI or MSDI values; usage in flavors is typically low, minimizing potential risk.
• Dermal Exposure: Generally considered safe in fragrance applications, though IFRA guidelines should be consulted for specific restrictions.
• Inhalation Exposure: Volatility suggests potential for inhalation exposure, but no specific occupational hazards have been reported.

Overall, the risk profiles for food and fragrance applications are considered low when used within industry-standard concentrations.

8. Practical Insights for Formulators

Cyclamen homoaldehyde is valued for its ability to enhance floral and green notes in both flavors and fragrances. It synergizes well with other floral compounds, such as linalool and geraniol, to create balanced and complex profiles.

Common formulation pitfalls include overuse, which can lead to an overpowering or artificial aroma. It is often under-used in formulations seeking subtlety and nuance.

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.
