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 agarwood oil is 1333524-00-7. While it does not have a specific FEMA number, it is recognized in the fragrance and flavor industry for its unique properties. The oil is primarily composed of sesquiterpenes and chromones, which contribute to its characteristic scent profile. The composition of agarwood oil can vary significantly depending on the origin, harvest conditions, and processing methods.

2. Sensory Profile

Agarwood oil is renowned for its complex and multi-layered sensory profile. It is often described as having a deep, woody, and balsamic aroma with sweet, spicy, and slightly animalic undertones. The intensity of the scent can vary, but it is generally considered to be strong and long-lasting. The oil is used as an impact note in both fragrances and flavors, providing a rich and exotic character. While specific taste and odor thresholds are not well-documented, its potent aroma means it is typically used in small quantities to achieve the desired 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, resinous heartwood. This process can take several years and is influenced by environmental factors. Agarwood oil is considered a natural fragrance and flavor material due to its direct extraction from plant sources without synthetic modification.

4. Use in Flavors

In the flavor industry, agarwood oil is used to impart a unique, exotic note to various products. It is commonly found in luxury food items and beverages, where it serves as a background realism enhancer or a modifier. Typical use levels in finished products are not well-documented, but industry estimates suggest concentrations in the range of 0.1 to 5 ppm, depending on the desired intensity and application. The oil is relatively stable under normal conditions but may degrade under extreme heat or acidic environments.

5. Use in Fragrances

Agarwood oil is highly valued in the fragrance industry, particularly in oriental and woody fragrance families. It is used as a base note due to its low volatility and long-lasting scent. The oil provides depth and complexity to perfumes, often serving as a trace realism or impact note. Typical concentration ranges in fragrances vary from 0.5% to 5%, depending on the formulation and desired effect. Its rich aroma makes it a popular choice for high-end and niche perfumes.

5a. Key Constituents (Typical)

Agarwood oil is composed of several key constituents, including agarospirol, jinkoh-eremol, and various chromones. These compounds are responsible for the oil's distinctive aroma and are present in varying concentrations depending on the source and processing method. The composition can vary significantly, making it essential for formulators to verify the specific profile of the oil they are using.

6. Regulatory Status (Regional Overview)

In the United States, agarwood oil is not explicitly listed as GRAS by FEMA but is used in flavors and fragrances under general safety guidelines. In the European Union, it is subject to the regulations outlined in Reg. (EC) No 1334/2008, with its use in flavors and fragrances being harmonized under general safety standards. The United Kingdom follows similar regulations post-Brexit. In Asia, particularly in Japan and China, agarwood oil is used traditionally, with specific regulations varying by country. In Latin America, its use is generally aligned with international standards, though specific country regulations may apply.

7. Toxicology, Safety & Exposure Considerations

Agarwood oil is generally considered safe for use in both flavors and fragrances when used within recommended concentrations. Oral exposure through flavor use is minimal, with no specific ADI or MSDI established. Dermal exposure in fragrances is more common, and while the oil is not known to be a strong irritant or sensitizer, formulators should adhere to IFRA guidelines to ensure safety. Inhalation exposure is primarily relevant in occupational settings, where adequate ventilation and protective measures should be in place to minimize risk.

8. Practical Insights for Formulators

Agarwood oil is prized for its ability to add depth and complexity to both flavors and fragrances. It synergizes well with other woody and oriental notes, enhancing the overall richness of a formulation. However, its potent aroma means it can easily overpower other components if not used judiciously. Formulators should be mindful of its variability in composition and ensure consistency by sourcing from reputable suppliers.

9. Confidence & Data Quality Notes

The data on agarwood oil is well-established in terms of its sensory profile and general use in the industry. However, specific quantitative data on use levels and safety thresholds are less documented, relying on industry-typical practices. There are known gaps in regulatory clarity across different regions, necessitating careful review by formulators to ensure compliance.

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.
