FlavScents AInsights Entry: Leontopodium Alpinum Extract (CAS: 391900-47-3)

1. Identity & Chemical Information

Leontopodium alpinum extract, commonly known as Edelweiss extract, is a natural complex material derived from the Leontopodium alpinum plant. This extract is not a single chemical compound but a mixture of various constituents. The CAS number for this extract is 391900-47-3. It does not have a specific FEMA number or other identifiers like FL number or CoE number due to its complex nature. As a natural extract, it is characterized by its diverse composition, which can vary significantly depending on the source, harvest time, and processing methods.

2. Sensory Profile

Leontopodium alpinum extract is known for its subtle, floral aroma with earthy and musky undertones. The intensity of its odor is generally mild, making it suitable for use as a background note in both flavors and fragrances. The extract does not have a well-documented taste or odor threshold, but it is typically used to impart a natural, alpine freshness to formulations. Its sensory role is often as a modifier or to add realism to floral compositions.

3. Natural Occurrence & Formation

Leontopodium alpinum, commonly known as Edelweiss, is native to the mountainous regions of Europe, particularly the Alps. The extract is obtained from the flowers and leaves of the plant. As a natural product, it is often used in formulations labeled as "natural flavor" or "natural fragrance." The formation of its characteristic aroma is primarily due to the presence of various terpenes and phenolic compounds, which are naturally occurring in the plant.

4. Use in Flavors

In the flavor industry, Leontopodium alpinum extract is used to impart a subtle floral note to products. It is commonly found in herbal teas, confectionery, and specialty beverages. The typical use levels in finished food or beverage products range from 5 to 50 ppm, depending on the desired intensity and the complexity of the flavor profile. The extract is relatively stable under normal processing conditions but may degrade under high heat or extreme pH conditions.

5. Use in Fragrances

Leontopodium alpinum extract is utilized in the fragrance industry for its delicate floral scent. It is often included in fragrance families such as floral, green, and woody compositions. The extract serves as a modifier or background note, providing a natural and fresh alpine character. Typical concentration ranges in fragrance formulations are from 0.1% to 1%, depending on the desired effect. It contributes primarily to the middle notes of a fragrance due to its moderate volatility.

5a. Key Constituents (Typical)

The key constituents of Leontopodium alpinum extract include terpenes such as linalool and geraniol, as well as phenolic compounds like chlorogenic acid. The composition of the extract can vary significantly based on factors such as geographic origin, harvest time, and extraction method. These constituents are responsible for the extract's characteristic aroma and potential antioxidant properties.

6. Regulatory Status (Regional Overview)

In the United States, Leontopodium alpinum extract is generally recognized as safe (GRAS) for use in flavors. In the European Union, it is regulated under Regulation (EC) No 1334/2008, and its use in flavors is permitted. The United Kingdom follows similar regulations post-Brexit. In Asia, the extract is accepted in countries like Japan and China, although specific regulations may vary. In Latin America, countries such as Brazil and members of MERCOSUR have their own regulatory frameworks, which generally align with international standards.

7. Toxicology, Safety & Exposure Considerations

For oral exposure, Leontopodium alpinum extract is considered safe at typical use levels in food and beverages, with no specific ADI or MSDI established. Dermal exposure in fragrances is generally safe, with no significant reports of irritation or sensitization, although IFRA guidelines should be consulted for specific applications. Inhalation exposure is minimal due to its moderate volatility, but occupational safety measures should be observed during handling and processing.

8. Practical Insights for Formulators

Leontopodium alpinum extract is valued for its ability to impart a natural, alpine freshness to both flavors and fragrances. It synergizes well with other floral and green notes, enhancing the overall complexity of a formulation. Common pitfalls include overuse, which can lead to an overpowering floral character, and underuse, which may result in a lack of desired freshness. Formulators should carefully balance its concentration to achieve the optimal sensory 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.
