FlavScents AInsights Entry: Beta-Caryophyllene Oxide

1. Identity & Chemical Information

Common Name(s): Beta-caryophyllene oxide
IUPAC Name: (1R,4R,6R,10S)-4,11,11-trimethyl-8-methylidenebicyclo[7.2.0]undec-8-ene-4,6-epoxide
CAS Number: 1139-30-6
FEMA Number: 3445
Other Identifiers: FL No. 02.062
Molecular Formula: C15H24O
Molecular Weight: 220.35 g/mol
Functional Groups and Structure-Odor Relevance: Beta-caryophyllene oxide is a bicyclic sesquiterpene oxide. The presence of the epoxide group is significant for its reactivity and contributes to its distinct odor profile, which is often described as woody and spicy.

Citation hooks: FlavScents; PubChem; FEMA

2. Sensory Profile

Beta-caryophyllene oxide is characterized by a woody, spicy aroma with a hint of sweetness. It is often described as having a moderate intensity and a warm, diffusive quality. The compound is used as an impact note in fragrance compositions, providing a sense of depth and complexity. While specific taste and odor thresholds are not well-documented, it is known to contribute significantly to the overall sensory profile of products in which it is used.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Beta-caryophyllene oxide is naturally found in a variety of essential oils, including those from clove, rosemary, and hops. It is formed through the oxidation of beta-caryophyllene, a common sesquiterpene found in many plant species. This compound is often used in products labeled as "natural flavor" or "natural fragrance" due to its natural occurrence in these essential oils.

Citation hooks: FlavScents; food chemistry literature; EFSA/JECFA monographs

4. Use in Flavors

Beta-caryophyllene oxide is utilized in flavor formulations primarily within the spice and herbal categories. It serves as a functional component that enhances the depth and realism of flavor systems. Typical use levels in finished food or beverage products range from 0.1 to 5 ppm, with variations depending on the specific application and desired flavor profile. It is relatively stable under typical processing conditions, though care should be taken to avoid excessive heat and oxidation, which can degrade its sensory qualities.

5. Use in Fragrances

In the fragrance industry, beta-caryophyllene oxide is valued for its woody and spicy notes, making it a popular choice in oriental and woody fragrance families. It acts as a modifier and impact note, often used in concentrations ranging from trace amounts to 1% in finished products. Its volatility places it in the middle to base note category, contributing to the longevity and complexity of the fragrance.

6. Regulatory Status (Regional Overview)

United States: Recognized as GRAS by FEMA for flavor use.
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 reported.
Asia: Approved for use in Japan and China, with specific regulations varying by country.
Latin America: Generally accepted in Brazil and MERCOSUR countries, though specific regulations should be consulted.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

For oral exposure, beta-caryophyllene oxide is considered safe at typical use levels, with no specific ADI or MSDI established. Dermal exposure in fragrance applications is generally well-tolerated, though IFRA guidelines should be consulted to avoid potential sensitization. Inhalation exposure is not typically a concern at standard usage levels, but occupational safety measures should be observed in manufacturing settings.

Citation hooks: EFSA; FEMA; PubChem; toxicology literature

8. Practical Insights for Formulators

Beta-caryophyllene oxide is prized for its ability to impart a warm, spicy character to both flavors and fragrances. It synergizes well with other woody and spicy notes, enhancing the overall complexity of the formulation. Formulators should be cautious of its potential to overpower more delicate notes if used excessively. It is often under-utilized in formulations seeking a natural profile, despite its versatility and effectiveness.

Citation hooks: FlavScents; industry practice

9. Confidence & Data Quality Notes

The data on beta-caryophyllene oxide is well-established, particularly regarding its sensory characteristics and natural occurrence. While specific quantitative thresholds are less documented, industry practices provide a reliable framework for its use. Regulatory information is comprehensive, though formulators should remain aware of regional variations.

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.
