FlavScents AInsights Entry: Galbanum Oil (CAS: 8023-91-4)

1. Identity & Chemical Information

Galbanum oil is a natural complex material derived from the resin of the Ferula genus, particularly Ferula gummosa. It is not a single chemical compound but a mixture of various constituents. The CAS number for galbanum oil is 8023-91-4. It does not have a specific FEMA number due to its complex nature. Other identifiers include its FL number and CoE number, which are used in flavor and fragrance regulatory contexts. The composition of galbanum oil can vary significantly depending on its geographical origin, harvest time, and processing methods.

2. Sensory Profile

Galbanum oil is renowned for its distinctive green, balsamic, and woody odor profile. It is often described as having a sharp, fresh, and slightly spicy scent with earthy undertones. The intensity of its aroma is quite pronounced, making it a potent impact note in both flavors and fragrances. While specific taste and odor thresholds are not well-documented, galbanum oil is typically used in small amounts due to its strong sensory impact. It serves as a modifier and impact note, adding complexity and depth to formulations.

3. Natural Occurrence & Formation

Galbanum oil is naturally sourced from the resin of Ferula species, primarily Ferula gummosa, which is native to Iran and other parts of the Middle East. The resin is collected and then steam-distilled to produce the essential oil. Galbanum oil is considered a natural fragrance and flavor material, aligning with the "natural flavor" designation due to its direct derivation from plant sources without synthetic modification.

4. Use in Flavors

In flavor applications, galbanum oil is used to impart a green, fresh note to a variety of products, including beverages, confectionery, and savory items. It functions as a background realism enhancer and a modifier. Typical use levels in finished food products range from 0.1 to 5 ppm, depending on the desired intensity and the specific application. Galbanum oil is relatively stable under normal processing conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

Galbanum oil is a versatile ingredient in perfumery, used across various fragrance families such as chypre, fougère, and green floral compositions. It acts as a top to middle note, providing freshness and complexity. Typical concentration ranges in fragrance formulations are from trace amounts up to 2%, depending on the desired effect. Its volatility contributes to its role as a top note, while its tenacity allows it to linger as a middle note.

5a. Key Constituents (Typical)

Galbanum oil contains several key constituents, including β-pinene, α-pinene, limonene, and myrcene, which contribute to its characteristic aroma. The composition can vary based on factors such as geographic origin and processing methods. These constituents are responsible for the oil's green and balsamic notes.

6. Regulatory Status (Regional Overview)

In the United States, galbanum 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 has aligned with EU regulations. In Asia, regulatory status varies, with Japan and China having specific guidelines for natural flavor materials. In Latin America, countries like Brazil follow MERCOSUR regulations, which generally align with international standards.

7. Toxicology, Safety & Exposure Considerations

For oral exposure, galbanum oil is considered safe at typical flavor use levels, with no specific ADI or MSDI established. Dermal exposure in fragrance applications may pose a risk of irritation or sensitization, and formulators should adhere to IFRA guidelines. Inhalation exposure is generally low risk due to its use in small quantities, but occupational exposure should be minimized through proper handling practices. The risk profiles for food and fragrance applications are similar, with dermal exposure being the primary concern in fragrances.

8. Practical Insights for Formulators

Galbanum oil is valued for its ability to impart a fresh, green note that enhances the complexity of both flavors and fragrances. It synergizes well with citrus, woody, and floral notes. Common pitfalls include overuse, which can lead to an overpowering scent or flavor. It is often under-used in formulations seeking a natural green note due to its strong impact.

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.
