2. Sensory Profile

Bergoxane is known for its woody, earthy, and slightly sweet aroma, often described as reminiscent of patchouli or cedarwood. It has a moderate intensity and diffusion, making it suitable for use as a background note or modifier in both flavors and fragrances. The material is valued for its ability to impart a natural, grounding character to compositions. Specific odor thresholds are not well-documented, but its sensory impact is typically subtle yet persistent.

3. Natural Occurrence & Formation

Bergoxane is primarily found in the essential oils of certain plants, particularly those in the Lauraceae family. It is formed through the natural biosynthesis of terpenes within these plants. As a naturally occurring compound, bergoxane can be used to support "natural flavor" or "natural fragrance" claims, depending on its source and processing.

4. Use in Flavors

In flavor applications, bergoxane is used to impart woody and earthy notes, often in conjunction with other natural materials to enhance complexity and depth. It is commonly used in savory applications, such as in sauces and seasonings, as well as in certain beverage formulations. Typical use levels in finished products range from 0.1 to 5 ppm, depending on the desired intensity and the matrix of the product. Bergoxane is generally stable under typical processing conditions, though it may be sensitive to high heat and prolonged exposure to air.

5. Use in Fragrances

Bergoxane is utilized in a variety of fragrance families, including woody, oriental, and chypre. It serves as a modifier or background note, providing a natural, earthy base that enhances the overall complexity of the fragrance. Typical concentration ranges in formulations are from 0.1% to 2%, depending on the desired effect and product type. Bergoxane contributes primarily to the base notes of a fragrance due to its moderate volatility.

7. Toxicology, Safety & Exposure Considerations

• Oral Exposure: Data not found for specific ADI or MSDI values. General safety is assumed based on natural occurrence and historical use.
• Dermal Exposure: Generally considered safe for use in fragrances, though specific IFRA guidelines should be consulted for concentration limits.
• Inhalation Exposure: No specific occupational exposure limits identified; typical use in consumer products is considered safe.

Risk profiles may differ slightly between food and fragrance applications due to differences in exposure routes and concentrations.

8. Practical Insights for Formulators

Bergoxane is valued for its ability to impart a natural, earthy character to both flavors and fragrances. It synergizes well with other woody and spicy notes, enhancing the overall complexity of a formulation. Common pitfalls include overuse, which can lead to an overpowering or unbalanced profile. It is often underutilized in formulations seeking a subtle, natural enhancement.

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.
