Dextro,laevo-muscone is a macrocyclic ketone with a musky odor, primarily used in fragrance applications. Its structure consists of a 15-membered ring with a ketone functional group, which is crucial for its characteristic musky scent. The stereochemistry of muscone significantly influences its olfactory properties, with the (R)-enantiomer being more potent.

2. Sensory Profile
Muscone is renowned for its rich, animalic musk odor, which is both intense and diffusive. It is often described as having a warm, sweet, and slightly earthy character. The odor threshold of muscone is relatively low, making it a powerful impact note in fragrance compositions. In flavor applications, muscone is less commonly used but can impart a subtle muskiness that enhances the complexity of certain profiles.

3. Natural Occurrence & Formation
Muscone is naturally found in the musk gland of the male musk deer, although synthetic production is now more common due to ethical and sustainability concerns. It can also be found in small quantities in some plants and is formed through the oxidation of muscone precursors. Muscone's presence in natural sources allows it to be designated as a "natural fragrance" under certain regulatory frameworks.

4. Use in Flavors
Muscone is used sparingly in flavor applications due to its potent odor. It can be found in flavor categories such as dairy and confectionery, where it adds depth and complexity. Typical use levels in food are very low, often in the range of 0.01 to 0.1 ppm, to avoid overpowering other flavor notes. Muscone is stable under typical food processing conditions, including heat and pH variations.

5. Use in Fragrances
Muscone is a key component in many fragrance families, including oriental, floral, and woody compositions. It serves as a base note, providing longevity and depth to perfumes. Typical concentrations in fragrances range from 0.1% to 1%, depending on the desired intensity and character. Muscone's volatility is moderate, contributing to its role as a middle to base note in fragrance formulations.

6. Regulatory Status (Regional Overview)
- United States: Muscone is approved for use in flavors and fragrances, with FEMA GRAS status.
- European Union: Listed under Regulation (EC) No 1334/2008 with an assigned FL number.
- United Kingdom: Follows EU regulations post-Brexit with no significant divergence.
- Asia: Approved in Japan and China for use in fragrances; specific flavor regulations may vary.
- Latin America: Generally accepted in MERCOSUR countries, with specific national regulations applicable.
Muscone's regulatory status is well-established, with harmonized approvals across major markets. However, formulators should verify specific country requirements due to potential variability.

7. Toxicology, Safety & Exposure Considerations
Muscone is considered safe for use in both flavors and fragrances at typical exposure levels. Oral exposure through flavor use is minimal, with an acceptable daily intake (ADI) not clearly reported but generally recognized as safe. Dermal exposure in fragrances is well-tolerated, with low potential for irritation or sensitization. Inhalation exposure is primarily relevant for occupational settings, where standard safety precautions should be observed.

8. Practical Insights for Formulators
Muscone is valued for its ability to impart a rich, musky character to both flavors and fragrances. It synergizes well with floral and woody notes, enhancing the overall complexity of compositions. Formulators should be cautious of its potency, as overuse can lead to an overpowering scent. It is often under-utilized in flavor applications due to its strong odor, but when used judiciously, it can add a unique dimension.

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.
