FlavScents AInsights Entry for Davanone (CAS: 20482-11-5)

1. Identity & Chemical Information

Davanone is a chemical compound commonly used in the flavor and fragrance industry. Its IUPAC name is 2,6,6-Trimethyl-2-cyclohexene-1-one. The CAS number for davanone is 20482-11-5. While a FEMA number is not explicitly listed, it is recognized in various industry databases. The molecular formula of davanone is C10H16O, and it has a molecular weight of 152.23 g/mol. Davanone contains a cyclohexene ring with a ketone functional group, which contributes to its characteristic odor profile. The presence of methyl groups influences its volatility and sensory attributes, making it a valuable component in both flavor and fragrance formulations.

2. Sensory Profile

Davanone is known for its distinctive odor, often described as herbal, woody, and slightly camphoraceous. It has a moderate intensity and diffusion, making it suitable for use as a background note or modifier in complex fragrance compositions. The taste and odor thresholds for davanone are not well-documented, but it is typically used in low concentrations due to its potent sensory impact. In flavor applications, davanone can enhance herbal and woody notes, providing depth and complexity to the overall profile.

3. Natural Occurrence & Formation

Davanone is naturally found in certain essential oils, such as those derived from the plant Artemisia pallens, commonly known as davana. The compound is biosynthesized in plants through enzymatic pathways involving the cyclization of terpenoid precursors. Its presence in natural sources qualifies it for use in products labeled as containing "natural flavors" or "natural fragrances," depending on the regulatory definitions in different regions.

4. Use in Flavors

In the flavor industry, davanone is used to impart herbal and woody notes to a variety of products, including beverages, confectionery, and savory items. It functions as a modifier, enhancing the complexity and authenticity of flavor profiles. Typical use levels in finished food or beverage products range from 0.1 to 5 ppm, depending on the desired intensity and the specific application. Davanone is relatively stable under normal processing conditions, but formulators should consider its potential sensitivity to oxidation.

5. Use in Fragrances

Davanone is utilized in the fragrance industry for its unique herbal and woody aroma, fitting well within chypre and fougère fragrance families. It serves as a trace realism note or modifier, adding depth and complexity to perfumes and personal care products. Typical concentration ranges in fragrance formulations are from 0.01% to 0.1%, depending on the desired effect and product type. Davanone contributes primarily to the middle notes of a fragrance composition, offering moderate volatility.

6. Regulatory Status (Regional Overview)

In the United States, davanone is generally recognized as safe (GRAS) for use in flavors by FEMA. In the European Union, it is subject to the regulations outlined in Regulation (EC) No 1334/2008, with specific FL number status not clearly reported. The United Kingdom follows similar regulations post-Brexit. In Asia, including Japan and China, davanone's use is permitted under certain conditions, though specific regulatory details may vary. In Latin America, countries like Brazil and those in MERCOSUR have harmonized regulations that generally align with international standards.

7. Toxicology, Safety & Exposure Considerations

Davanone's safety profile is well-established for oral exposure in flavor applications, with an acceptable daily intake (ADI) not clearly reported but considered safe at typical use levels. For dermal exposure in fragrances, davanone is not known to cause significant irritation or sensitization, though formulators should adhere to IFRA guidelines. Inhalation exposure is generally considered low risk due to its moderate volatility, but occupational safety measures should be observed in manufacturing settings. The risk profiles for food and fragrance applications are similar, with no significant differences noted.

8. Practical Insights for Formulators

Davanone is valued for its ability to impart herbal and woody notes, enhancing the complexity of both flavor and fragrance formulations. It synergizes well with other terpenoid compounds, such as linalool and geraniol, to create balanced profiles. Formulators should be cautious of its potent sensory impact, as overuse can lead to overpowering compositions. It is often under-utilized in formulations seeking subtle herbal nuances.

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.
