FlavScents AInsights Entry for Santalum Album Seed Oil (CAS: 246866-27-3)
1. Identity & Chemical Information
Santalum album seed oil, commonly known as sandalwood seed oil, is a natural complex material derived from the seeds of the Santalum album tree. It is not a single chemical compound but a mixture of various constituents. The CAS number for this material is 246866-27-3. While it does not have a specific FEMA number, it is recognized in various fragrance and flavor applications. Other identifiers such as FL numbers or CoE numbers are not typically assigned to this material due to its complex nature. The composition of santalum album seed oil can vary significantly depending on the geographical origin, harvest time, and processing methods used.

2. Sensory Profile
Santalum album seed oil is characterized by a rich, woody aroma with creamy and slightly sweet undertones. It is often described as having a soft, balsamic scent that is both calming and grounding. The intensity of the odor is moderate, making it suitable for use as a background note in both flavors and fragrances. The oil's diffusion is relatively slow, contributing to its role as a base note in perfumery. Specific taste and odor thresholds are not well-documented, but its sensory role is primarily as a modifier and enhancer of other notes.

3. Natural Occurrence & Formation
Santalum album seed oil is naturally sourced from the seeds of the Santalum album tree, commonly known as Indian sandalwood. This tree is native to southern India and parts of Southeast Asia. The oil is extracted through cold pressing or solvent extraction methods. As a natural product, it qualifies for "natural flavor" or "natural fragrance" designations, depending on the extraction and processing methods used. The formation of its characteristic aroma is primarily due to the presence of sesquiterpenes and other volatile compounds.

4. Use in Flavors
In flavor applications, santalum album seed oil is used to impart a woody, creamy note to various products. It is commonly found in flavor categories such as vanilla, chocolate, and certain spice blends. The oil acts as a background realism enhancer, providing depth and complexity to flavor systems. Typical use levels in finished food or beverage products range from 0.5 to 5 ppm, with variations depending on the desired intensity and product type. The oil is relatively stable under normal processing conditions but may degrade under high heat or prolonged exposure to air.

5. Use in Fragrances
Santalum album seed oil is a valuable component in the fragrance industry, particularly in the creation of oriental, woody, and chypre fragrance families. It serves as a base note, providing longevity and depth to the fragrance composition. Typical concentration ranges in perfumes and personal care products vary from 0.1% to 2%, depending on the desired olfactory impact. The oil's low volatility makes it an excellent fixative, helping to stabilize more volatile top and middle notes.

5a. Key Constituents (Typical)
The key constituents of santalum album seed oil include sesquiterpenes such as α-santalol, β-santalol, and other related compounds. These constituents are responsible for the oil's characteristic aroma and therapeutic properties. The composition can vary significantly based on factors such as geographic origin and extraction method, 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, santalum album seed oil is generally recognized as safe (GRAS) for use in flavors, although specific regulatory approvals may vary. In the European Union, it is subject to Regulation (EC) No 1334/2008, with its use in flavors and fragrances being harmonized under this framework. The United Kingdom follows similar regulations post-Brexit, with minor divergences. In Asia, countries like Japan and China have their own regulatory frameworks, which generally align with international standards. In Latin America, countries such as Brazil and members of MERCOSUR have specific guidelines for natural flavor and fragrance materials.

7. Toxicology, Safety & Exposure Considerations
Santalum album seed oil is considered safe for use in both flavor and fragrance applications when used within recommended levels. Oral exposure through flavor use is generally low, with no specific ADI or MSDI established. Dermal exposure in fragrance use is also considered safe, with no significant reports of irritation or sensitization. The oil's low volatility minimizes inhalation exposure risks, although occupational safety measures should be observed during handling and processing. Overall, the risk profiles for food and fragrance applications are similar, with no significant differences noted.

8. Practical Insights for Formulators
Santalum album seed oil is valued for its ability to impart a rich, woody aroma and enhance the depth of both flavors and fragrances. It synergizes well with other woody and oriental notes, as well as with creamy and sweet accords. Formulators should be aware of its potential to overpower more delicate notes if used excessively. It is often under-used in flavor applications due to its subtlety, but when balanced correctly, it can significantly enhance the overall profile.

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.
