FlavScents AInsights Entry for Agarwood Oil (Aetoxylon sympetalum) (CAS: 1333524-00-7)

1. Identity & Chemical Information

Agarwood oil, derived from the species Aetoxylon sympetalum, is a complex natural material known for its rich and distinctive aroma. It is not a single chemical compound but a mixture of various constituents. The CAS number for this specific type of agarwood oil is 1333524-00-7. While there is no specific FEMA number assigned to this oil, it is recognized in various fragrance and flavor compendiums. Other identifiers such as FL numbers or CoE numbers are not explicitly documented for this material. As a natural complex material, it does not have a single molecular formula or molecular weight. The composition of agarwood oil can vary significantly depending on factors such as the geographical origin, age of the tree, and extraction method used.

2. Sensory Profile

Agarwood oil is renowned for its deep, woody, and balsamic aroma, often described as warm, sweet, and slightly spicy. The intensity of its scent can vary, but it is generally considered to have a strong diffusion and a long-lasting presence. It is primarily used as an impact note in both flavors and fragrances, providing a unique and exotic character. The taste and odor thresholds for agarwood oil are not well-documented, but its potent aroma suggests that only small amounts are needed to achieve the desired sensory effect.

3. Natural Occurrence & Formation

Agarwood oil is naturally sourced from the heartwood of Aetoxylon sympetalum trees, which are native to Southeast Asia. The formation of agarwood occurs when the tree becomes infected with a specific type of mold, leading to the production of a dark, aromatic resin. This resin is then distilled to produce the oil. The natural occurrence of agarwood and its resinous formation are critical to its designation as a "natural fragrance" material. The process is complex and influenced by environmental factors, making each batch of oil unique.

4. Use in Flavors

In the realm of flavors, agarwood oil is used sparingly due to its intense aroma. It is typically found in luxury food products and beverages, where it imparts a unique, exotic note. The oil is used in flavor categories such as high-end confectionery, specialty teas, and gourmet sauces. Typical use levels in finished products are not well-documented, but industry estimates suggest a range of 0.1 to 5 ppm, depending on the application. Agarwood oil is relatively stable under normal conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

Agarwood oil is highly prized in the fragrance industry, particularly in oriental and woody fragrance families. It serves as a base note, providing depth and longevity to perfumes. The oil is used in a variety of product types, including fine fragrances, incense, and luxury personal care products. Typical concentration ranges in perfumes can vary from trace amounts to several percent, depending on the desired intensity. Its volatility is low, contributing to its role as a base note.

5a. Key Constituents (Typical)

The key constituents of agarwood oil include sesquiterpenes such as agarospirol, jinkoh-eremol, and oxo-agarospirol. These compounds are primarily responsible for the oil's characteristic aroma. The composition of agarwood oil can vary significantly based on factors such as the tree's origin, age, and the extraction method used. It is important to note that the exact profile of constituents can differ from one batch to another.

6. Regulatory Status (Regional Overview)

In the United States, agarwood oil is not explicitly listed as GRAS by FEMA, but it is used in flavors and fragrances under general safety guidelines. In the European Union, it falls under the scope of Regulation (EC) No 1334/2008 for flavorings, although specific FL numbers are not assigned. The regulatory status in the United Kingdom aligns with the EU post-Brexit. In Asia, particularly in Japan and China, agarwood oil is used in traditional products, but specific regulatory details are limited. In Latin America, the use of agarwood oil is less documented, with Brazil and MERCOSUR countries following general safety standards.

7. Toxicology, Safety & Exposure Considerations

The safety profile of agarwood oil varies depending on its use. For oral exposure in flavors, specific ADI or MSDI values are not available, but it is used at low levels due to its potency. Dermal exposure in fragrances is generally considered safe, although IFRA guidelines should be consulted to avoid irritation or sensitization. Inhalation exposure is primarily relevant in occupational settings, where adequate ventilation is recommended to minimize risks. Overall, the risk profiles for food and fragrance applications are similar, with low exposure levels mitigating potential safety concerns.

8. Practical Insights for Formulators

Agarwood oil is valued for its unique and luxurious aroma, making it a sought-after ingredient in high-end products. It synergizes well with other woody and oriental notes, enhancing the depth and complexity of formulations. Common pitfalls include overuse, which can overwhelm other components, and variability in oil quality, which can affect consistency. Formulators should carefully balance agarwood oil with other ingredients to achieve the desired effect without overpowering the blend.

9. Confidence & Data Quality Notes

The data on agarwood oil is well-established in terms of its sensory profile and key constituents. However, specific regulatory details and safety data are less documented, leading to reliance on industry-typical practices. Known data gaps include precise use levels in flavors and comprehensive toxicological evaluations. Despite these gaps, the material is widely used and accepted in the industry.

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.
