2. Sensory Profile

Delta-muscenone is characterized by its musky odor, often described as warm and animalic with a subtle fruity undertone. It is known for its moderate intensity and good diffusion properties, making it a valuable impact note in both flavors and fragrances. The odor threshold is not clearly reported, but it is typically used in trace amounts due to its potent aroma.

3. Natural Occurrence & Formation

Delta-muscenone is not commonly found in nature and is primarily synthesized for use in flavors and fragrances. It does not have a significant natural occurrence, which limits its designation as a "natural flavor" or "natural fragrance" component. Its formation is typically achieved through synthetic organic chemistry processes.

4. Use in Flavors

Delta-muscenone is used in flavor formulations to impart a musky, animalic note that can enhance the complexity of a flavor profile. It is often used in trace amounts, typically ranging from 0.1 to 1 ppm in finished food or beverage products. Its stability is generally good, but it may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

In fragrances, delta-muscenone is valued for its ability to add depth and warmth, fitting well within the musk fragrance family. It serves as a modifier and impact note, often used in concentrations ranging from 0.01% to 0.1% in the final product. Its volatility is moderate, contributing primarily to the middle and base notes of a fragrance composition.

6. Regulatory Status (Regional Overview)

• United States: Delta-muscenone does not have a specific FEMA GRAS status.
• European Union: It is not explicitly listed under Regulation (EC) No 1334/2008.
• United Kingdom: Post-Brexit regulatory alignment with the EU is assumed, but specific divergence is not documented.
• Asia: Limited information is available; formulators should verify compliance with local regulations.
• Latin America: Specific regulatory status is not well-documented; harmonized assumptions may apply.

7. Toxicology, Safety & Exposure Considerations

• Oral Exposure: Data not found for ADI or MSDI; use in flavors is typically at low ppm levels, suggesting a wide margin of safety.
• Dermal Exposure: No specific IFRA restrictions; generally considered safe at typical fragrance concentrations.
• Inhalation Exposure: Moderate volatility suggests low occupational risk; standard ventilation practices are recommended.

8. Practical Insights for Formulators

Delta-muscenone is prized for its ability to add a musky depth to both flavors and fragrances. It synergizes well with floral and fruity notes, enhancing overall complexity. Formulators should be cautious of its potency, as overuse can lead to an overpowering aroma. It is often under-utilized in natural-themed products due to its synthetic origin.

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.
