FlavScents AInsights Entry for Artemisia Herba-Alba Leaf Oil (CAS: 84775-75-7)

1. Identity & Chemical Information

Artemisia herba-alba leaf oil, commonly known as white wormwood oil, is a complex natural material derived from the leaves of the Artemisia herba-alba plant. It is not a single chemical compound but a mixture of various constituents. The CAS number for this essential oil is 84775-75-7. While it does not have a specific FEMA number due to its complex nature, it is recognized in various fragrance and flavor compendiums. The oil is characterized by its diverse chemical composition, which includes monoterpenes, sesquiterpenes, and other volatile compounds that contribute to its unique sensory properties.

2. Sensory Profile

Artemisia herba-alba leaf oil is known for its distinctive, herbaceous, and camphoraceous odor profile. It exhibits a strong, penetrating aroma with notes of sage and a hint of bitterness. The intensity of its scent makes it a potent impact note in both flavor and fragrance applications. While specific taste and odor thresholds are not well-documented, the oil is typically used in small quantities due to its strong diffusion and character. It serves as a modifier and impact note, adding complexity and depth to formulations.

3. Natural Occurrence & Formation

Artemisia herba-alba is native to arid regions of the Mediterranean, North Africa, and the Middle East. The essential oil is extracted from the leaves through steam distillation. The plant's natural habitat and growth conditions significantly influence the oil's composition, making it a candidate for "natural flavor" or "natural fragrance" designation. The formation of its key constituents is primarily through biosynthetic pathways typical of terpenoid production in plants.

4. Use in Flavors

In flavor applications, artemisia herba-alba leaf oil is used to impart a herbal, slightly bitter note to various products. It is commonly found in categories such as alcoholic beverages, herbal teas, and certain confectioneries. The typical use levels in finished products range from 0.1 to 5 ppm, depending on the desired intensity and product type. The oil is relatively stable under normal processing conditions but may degrade under prolonged exposure to heat and light.

5. Use in Fragrances

Artemisia herba-alba leaf oil is utilized in fragrance formulations for its strong, herbaceous aroma. It is a common component in chypre and fougère fragrance families, where it acts as a modifier and impact note. Typical concentration ranges in perfumes are from trace amounts up to 1%, depending on the desired effect. The oil contributes primarily to the top and middle notes due to its volatility.

5a. Key Constituents (Typical)

The key constituents of artemisia herba-alba leaf oil include camphor, 1,8-cineole, α-thujone, and β-thujone. These compounds are responsible for the oil's characteristic aroma and contribute to its sensory and functional properties. The composition can vary significantly based on the plant's geographic origin, harvest time, and distillation process.

6. Regulatory Status (Regional Overview)

In the United States, artemisia herba-alba leaf oil is generally recognized as safe (GRAS) for flavor use under FEMA guidelines. In the European Union, it is regulated under Regulation (EC) No 1334/2008, with specific FL number status. The United Kingdom follows similar regulations post-Brexit. In Asia, the oil is subject to varying regulations, with Japan and China having specific guidelines for its use. In Latin America, countries like Brazil and members of MERCOSUR have their own regulatory frameworks, often aligning with international standards.

7. Toxicology, Safety & Exposure Considerations

The safety of artemisia herba-alba leaf oil is evaluated based on its exposure routes. For oral exposure, the oil's use in flavors is considered safe within the typical ppm ranges, with no specific ADI or MSDI established. Dermal exposure in fragrances may pose risks of irritation or sensitization, particularly due to the presence of thujone. Inhalation exposure is generally low risk, but occupational safety measures should be considered due to its volatility. The risk profiles differ between food and fragrance applications, with more stringent controls in place for dermal exposure.

8. Practical Insights for Formulators

Artemisia herba-alba leaf oil is valued for its potent, herbaceous aroma, which can enhance the complexity of both flavors and fragrances. It synergizes well with other herbal and citrus notes but can easily overpower a formulation if not used judiciously. Common pitfalls include overuse, leading to an undesirable bitterness or medicinal quality. It is often underutilized in applications where a subtle herbal note could add depth.

9. Confidence & Data Quality Notes

The data on artemisia herba-alba leaf oil is well-established in terms of its sensory profile and typical uses. However, there are gaps in specific toxicological data and regulatory nuances across different regions. Industry practices often rely on historical usage patterns and expert judgment in the absence of comprehensive documentation.

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.
