FlavScents AInsights Entry: Sandalwood Oil (CAS: 8006-87-9)
1. Identity & Chemical Information
Sandalwood oil is a natural complex material derived from the heartwood of the sandalwood tree, primarily Santalum album. It is known for its rich, woody aroma and is widely used in both flavor and fragrance industries. The CAS number for sandalwood oil is 8006-87-9. It does not have a single IUPAC name or molecular formula due to its complex nature. However, its key constituents include santalol isomers, which are responsible for its characteristic scent. The oil is often referenced in industry standards such as FEMA and IFRA.

2. Sensory Profile
Sandalwood oil is renowned for its warm, creamy, and woody aroma with a subtle balsamic undertone. It is often described as having a soft, persistent scent that can act as a base note in perfumery, providing depth and longevity. The oil's sensory profile makes it a popular choice for creating a calming and grounding atmosphere. While specific odor thresholds are not well-documented, sandalwood oil is typically used in low concentrations due to its potent aroma.

3. Natural Occurrence & Formation
Sandalwood oil is primarily obtained from the heartwood of Santalum album trees, native to India and other parts of Southeast Asia. The oil is extracted through steam distillation, a process that preserves its aromatic compounds. As a natural product, it qualifies for "natural fragrance" designation. The composition of sandalwood oil can vary based on the tree's age, geographic origin, and extraction method.

4. Use in Flavors
In the flavor industry, sandalwood oil is used to impart a woody, creamy note to various products, including beverages, confectionery, and baked goods. It serves as a background realism enhancer and is typically used at low levels, often in the range of 0.1 to 5 ppm in finished products. The oil is stable under typical food processing conditions but may degrade under extreme heat or acidic environments.

5. Use in Fragrances
Sandalwood oil is a staple in the fragrance industry, used across various fragrance families such as oriental, woody, and floral. It acts as a base note, providing longevity and depth to perfumes. Typical concentration ranges in fragrances are from 1% to 5%, depending on the desired intensity. The oil's low volatility makes it an excellent fixative, helping to stabilize more volatile top and middle notes.

5a. Key Constituents (Typical)
The primary constituents of sandalwood oil include α-santalol and β-santalol, which together can comprise up to 90% of the oil. Other components may include santalene, santalenone, and various sesquiterpenes. The exact composition can vary significantly based on the source and extraction method.

6. Regulatory Status (Regional Overview)
In the United States, sandalwood oil is generally recognized as safe (GRAS) for use in flavors by FEMA. In the European Union, it is regulated under Regulation (EC) No 1334/2008 and has an assigned FL number. Post-Brexit, the UK follows similar regulations. In Asia, countries like Japan and China have specific guidelines for its use, often aligning with international standards. In Latin America, regulations can vary, with Brazil and MERCOSUR countries having their own frameworks.

7. Toxicology, Safety & Exposure Considerations
Sandalwood oil is considered safe for use in both flavors and fragrances when used within recommended limits. For oral exposure, the acceptable daily intake (ADI) is not explicitly defined, but it is used at low levels in food products. Dermal exposure in fragrances is generally safe, though it may cause irritation or sensitization in sensitive individuals. Inhalation exposure is typically low risk, but occupational exposure should be monitored to prevent respiratory irritation.

8. Practical Insights for Formulators
Sandalwood oil is valued for its unique aroma and fixative properties. It blends well with floral, citrus, and oriental notes, enhancing the overall complexity of a fragrance or flavor. Formulators should be cautious of overuse, as its potent aroma can dominate a blend. It is often underutilized in modern formulations due to cost, but its impact on product quality can justify its inclusion.

9. Confidence & Data Quality Notes
The data on sandalwood oil is well-established, with extensive documentation in both flavor and fragrance applications. However, variations in composition due to geographic and processing differences can lead to inconsistencies. Industry practices are generally well-documented, though some regional regulatory nuances may not be fully captured.

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.
