FlavScents AInsights Entry for Alpha-Copaene (CAS: 3856-25-5)

1. Identity & Chemical Information

Common Name(s): Alpha-copaene
IUPAC Name: (1S,2R,6S,7S,8S)-1,3,3,7-tetramethyltricyclo[4.4.0.0^{2,8}]dec-4-ene
CAS Number: 3856-25-5
FEMA Number: Not available
Other Identifiers: FL No. 09.931
Molecular Formula: C15H24
Molecular Weight: 204.35 g/mol

Alpha-copaene is a sesquiterpene hydrocarbon characterized by its tricyclic structure. The presence of multiple methyl groups and a double bond contributes to its distinctive odor profile, which is significant in both flavor and fragrance applications.

Citation hooks: FlavScents; PubChem; FEMA

2. Sensory Profile

Alpha-copaene is known for its woody, spicy, and slightly balsamic aroma. It is often described as having a warm, earthy scent with a hint of citrus. The compound's odor intensity is moderate, making it suitable as a background note or modifier in complex formulations. While specific taste and odor thresholds are not well-documented, alpha-copaene is typically used to enhance the depth and richness of a fragrance or flavor profile.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Alpha-copaene is naturally found in various essential oils, including those from copaiba, patchouli, and black pepper. It is biosynthesized in plants through the mevalonate pathway, which is common for terpenoids. The compound's presence in essential oils contributes to their designation as "natural flavors" or "natural fragrances," depending on the context of use.

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

4. Use in Flavors

Alpha-copaene is utilized in flavor formulations to impart woody and spicy notes, often enhancing the complexity of savory and spice blends. It is commonly found in flavor categories such as meat, spice, and herbal profiles. Typical use levels in finished food products range from 0.1 to 5 ppm, with variations depending on the desired intensity and application. The compound is relatively stable under normal processing conditions but may degrade under extreme heat or acidic environments.

5. Use in Fragrances

In fragrance applications, alpha-copaene is valued for its ability to add depth and warmth to woody and oriental fragrance families. It serves as a modifier or impact note, often used in concentrations ranging from trace amounts to 0.5% in the final product. Its volatility places it primarily in the middle to base notes of a fragrance composition, contributing to the longevity and richness of the scent.

6. Regulatory Status (Regional Overview)

United States: Alpha-copaene is not explicitly listed as a FEMA GRAS substance but is used in compliance with general safety standards.
European Union: It is included in the EU's list of flavoring substances under Regulation (EC) No 1334/2008.
United Kingdom: Post-Brexit regulations align closely with the EU, maintaining similar standards for flavor and fragrance use.
Asia: Regulatory status varies; in Japan, it is used under general flavoring guidelines, while specific approvals may be required in China and ASEAN countries.
Latin America: Usage is generally aligned with international standards, but specific national regulations should be consulted.

7. Toxicology, Safety & Exposure Considerations

Alpha-copaene's safety profile is primarily evaluated through its use in essential oils. Oral exposure in flavor applications is considered safe within typical use levels, although specific ADI or MSDI values are not clearly reported. Dermal exposure in fragrances is generally safe, with no significant reports of irritation or sensitization. Inhalation exposure is minimal due to its low volatility, but occupational safety measures should be observed during handling.

8. Practical Insights for Formulators

Alpha-copaene is prized for its ability to enhance the complexity and warmth of both flavors and fragrances. It synergizes well with other terpenes and can be used to balance or modify overly sharp or sweet notes. Formulators should be cautious of its potential to overpower delicate compositions if used excessively. It is often underutilized in formulations seeking a natural, earthy character.

9. Confidence & Data Quality Notes

The data on alpha-copaene is well-established in terms of its chemical identity and sensory characteristics. However, specific regulatory and toxicological data may be limited or vary by region. Industry practices often rely on empirical knowledge and historical usage patterns.

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.
