FlavScents AInsights Entry: Frankincense Absolute (CAS: 8016-36-2)

1. Identity & Chemical Information

Frankincense absolute is a complex natural material derived from the resin of Boswellia trees, primarily Boswellia sacra and Boswellia carterii. It is not a single chemical compound but a mixture of various constituents. The CAS number for frankincense absolute is 8016-36-2. While it does not have a specific FEMA number due to its complex nature, it is recognized in various fragrance and flavor compendiums. Other identifiers include its FL number and CoE number, which are used in regulatory contexts. The composition of frankincense absolute can vary significantly depending on the geographical origin, harvest time, and processing methods.

2. Sensory Profile

Frankincense absolute is renowned for its rich, balsamic, and slightly spicy aroma with a hint of citrus and woody undertones. It is often described as having a warm, resinous scent that is both calming and grounding. The intensity of its odor is moderate to strong, making it a prominent note in both fragrances and flavors. While specific taste and odor thresholds are not well-documented, frankincense is typically used as an impact note or a modifier to add depth and complexity to formulations.

3. Natural Occurrence & Formation

Frankincense is naturally sourced from the resin of Boswellia trees, which are native to the Arabian Peninsula and parts of Africa. The resin is collected by making incisions in the bark of the tree, allowing the sap to exude and harden. This hardened resin is then processed to produce the absolute. Frankincense is considered a natural fragrance and flavor material, aligning with consumer preferences for natural products. Its formation does not involve synthetic pathways, making it suitable for natural product labeling.

4. Use in Flavors

In flavor applications, frankincense absolute is used to impart a warm, spicy, and slightly citrusy note. It is commonly found in spice blends, confectionery, and beverages. The typical use levels in finished food products range from 1 to 10 ppm, depending on the desired intensity and the complexity of the flavor profile. Frankincense is relatively stable under normal processing conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

Frankincense absolute is a staple in the fragrance industry, used in a variety of fragrance families including oriental, woody, and spicy compositions. It serves as a base note, providing longevity and depth to perfumes. Typical concentration ranges in fragrances are from 0.1% to 5%, depending on the formulation. Its volatility is moderate, contributing to both the middle and base notes of a fragrance composition.

6. Regulatory Status (Regional Overview)

In the United States, frankincense absolute is generally recognized as safe (GRAS) for use in flavors by FEMA. In the European Union, it is regulated under Reg. (EC) No 1334/2008 and has an assigned FL number. The United Kingdom follows similar regulations post-Brexit. In Asia, countries like Japan and China have specific guidelines for natural flavor materials, while ASEAN countries may have varying regulations. In Latin America, Brazil and MERCOSUR countries recognize its use in both flavors and fragrances, with specific labeling requirements.

7. Toxicology, Safety & Exposure Considerations

Frankincense absolute is considered safe for use in both flavors and fragrances when used within recommended levels. Oral exposure through flavor use is generally low, with no specific ADI or MSDI established, but it is considered safe under typical use conditions. Dermal exposure in fragrances is also deemed safe, with low potential for irritation or sensitization, as supported by IFRA guidelines. Inhalation exposure is minimal, with no significant occupational hazards reported.

8. Practical Insights for Formulators

Frankincense absolute is valued for its unique aromatic profile and versatility in both flavors and fragrances. It blends well with citrus, spice, and woody notes, enhancing the overall complexity of a formulation. Formulators should be cautious of its intensity, as overuse can overpower other components. It is often underutilized in modern formulations, offering an opportunity for innovation in natural product lines.

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.
