FlavScents AInsights Entry for Beta-Bisabolene (CAS: 495-61-4)

1. Identity & Chemical Information

Common Name(s): Beta-Bisabolene
IUPAC Name: (S)-1-Methyl-4-(6-methylhept-5-en-2-yl)cyclohexene
CAS Number: 495-61-4
FEMA Number: Not available
Other Identifiers: FL number not available; CoE number not available; IFRA reference not available
Molecular Formula: C15H24
Molecular Weight: 204.35 g/mol

Beta-bisabolene is a sesquiterpene, characterized by its cyclohexene ring and multiple methyl groups, contributing to its distinct odor profile. The presence of the isoprene units in its structure is crucial for its volatility and odor characteristics, making it relevant in both flavor and fragrance applications.

2. Sensory Profile

Beta-bisabolene is known for its warm, woody, and slightly spicy aroma, often described as reminiscent of cedarwood or patchouli. Its intensity is moderate, providing a subtle yet persistent background note in formulations. The compound is typically used as a modifier or a background realism enhancer in both flavors and fragrances. Specific taste and odor thresholds are not well-documented, but its sensory impact is recognized in the industry for its ability to blend and enhance other notes.

3. Natural Occurrence & Formation

Beta-bisabolene is naturally found in a variety of essential oils, including those from ginger, lemon, and certain types of chamomile. It is biosynthesized in plants via the mevalonate pathway, a common route for terpenoid formation. Its presence in natural sources qualifies it for use in products labeled as "natural flavor" or "natural fragrance," depending on the extraction and processing methods.

4. Use in Flavors

Beta-bisabolene is utilized in flavor formulations primarily for its woody and spicy notes, which are valuable in creating complex profiles in beverages, confectionery, and savory products. It acts as a background note, enhancing the overall depth and realism of the flavor. Typical use levels in finished products range from 0.1 to 5 ppm, with variations depending on the desired intensity and product type. It is relatively stable under typical processing conditions but may degrade under extreme heat or oxidative environments.

5. Use in Fragrances

In fragrance applications, beta-bisabolene is incorporated into woody, spicy, and oriental fragrance families. It serves as a modifier and impact note, contributing to the complexity and warmth of the scent profile. Concentration ranges in formulations are typically low, often below 1%, due to its potent aroma. Its volatility places it in the middle to base note category, providing lasting depth to the fragrance.

6. Regulatory Status (Regional Overview)

United States: Not explicitly listed as FEMA GRAS; however, its natural occurrence in essential oils used in flavors may imply acceptance under certain conditions.
European Union: Not specifically listed under Regulation (EC) No 1334/2008; use may be subject to general flavoring regulations.
United Kingdom: Follows EU regulations post-Brexit with potential for future divergence.
Asia: Limited specific data; general acceptance in natural flavor contexts.
Latin America: Regulatory status varies; generally accepted in natural flavor contexts.

7. Toxicology, Safety & Exposure Considerations

For oral exposure, beta-bisabolene's safety profile is not well-documented with specific ADI or MSDI values, but its use in natural essential oils suggests a generally recognized as safe status at low concentrations. Dermal exposure in fragrance applications should consider potential irritation or sensitization, although specific IFRA guidelines are not available. Inhalation exposure is typically low risk due to its moderate volatility, but occupational exposure should be managed with standard safety practices.

8. Practical Insights for Formulators

Beta-bisabolene is valued for its ability to enhance and modify other notes, providing warmth and depth. It synergizes well with other woody and spicy components, but formulators should be cautious of its potential to overpower delicate compositions if used excessively. It is often under-utilized in formulations seeking a natural profile enhancement.

9. Confidence & Data Quality Notes

Data on beta-bisabolene is well-established in terms of its chemical identity and sensory profile, but gaps exist in specific regulatory approvals and detailed toxicological assessments. Industry practices often rely on its natural occurrence in essential oils for guidance on safe use levels.

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.
