FlavScents AInsights Entry: Farnesol (CAS: 4602-84-0)

1. Identity & Chemical Information

Common Name(s): Farnesol
IUPAC Name: 3,7,11-Trimethyldodeca-2,6,10-trien-1-ol
CAS Number: 4602-84-0
FEMA Number: 2470
Other Identifiers: FL No. 02.013
Molecular Formula: C15H26O
Molecular Weight: 222.37 g/mol

Farnesol is a sesquiterpene alcohol characterized by its linear structure with three double bonds and a terminal hydroxyl group. This structure contributes to its floral, sweet, and slightly citrus-like odor, making it valuable in both flavor and fragrance applications.

2. Sensory Profile

Farnesol is known for its delicate floral aroma, often described as sweet, fresh, and slightly citrusy. It is commonly used to impart a natural floral note in both flavors and fragrances. The compound has a moderate intensity and diffusion, making it suitable as a background realism enhancer or a subtle impact note. Specific taste and odor thresholds are not well-documented, but its sensory role is typically as a modifier or enhancer in complex formulations.

3. Natural Occurrence & Formation

Farnesol naturally occurs in a variety of essential oils, including citronella, neroli, cyclamen, lemon grass, tuberose, rose, and musk. It is biosynthesized in plants via the mevalonate pathway, a key metabolic route for the production of terpenoids. Farnesol's presence in these oils contributes to their designation as "natural flavors" or "natural fragrances," depending on the context of use.

4. Use in Flavors

Farnesol is utilized in flavor formulations primarily for its ability to enhance floral and citrus notes. It is commonly found in categories such as citrus, floral, and fruity flavors. Typical use levels in finished food or beverage products range from 0.1 to 5 ppm, with higher concentrations potentially leading to overpowering effects. Farnesol is relatively stable under normal processing conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

In the fragrance industry, farnesol is valued for its ability to impart a natural floral aroma. It is used across various fragrance families, including floral, citrus, and woody compositions. Farnesol acts as a modifier and impact note, often contributing to the middle notes of a fragrance. Typical concentration ranges in perfumes are from 0.1% to 1%, depending on the desired intensity and diffusion. Its volatility is moderate, allowing it to blend well with both top and middle notes.

6. Regulatory Status (Regional Overview)

United States: Farnesol is recognized as GRAS (Generally Recognized As Safe) by FEMA for flavor use.
European Union: Approved under Regulation (EC) No 1334/2008 with FL No. 02.013.
United Kingdom: Post-Brexit regulations align with EU standards.
Asia: In Japan and China, farnesol is permitted for use in flavors and fragrances, though specific regulatory details may vary.
Latin America: Generally accepted in MERCOSUR countries, with specific regulations varying by country.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Farnesol is considered safe for use in both flavors and fragrances when used within recommended limits.

Oral Exposure: The compound has a high margin of safety with no specific ADI established, but it is generally used at low concentrations in food.
Dermal Exposure: Farnesol can cause mild irritation or sensitization in sensitive individuals, and it is subject to IFRA guidelines for fragrance use.
Inhalation Exposure: As a volatile compound, farnesol poses minimal risk under normal use conditions, though occupational exposure should be monitored.

8. Practical Insights for Formulators

Farnesol is prized for its ability to enhance floral and citrus notes, providing a natural and fresh character to formulations. It synergizes well with other floral and citrus compounds, but care should be taken to avoid overuse, which can lead to an overpowering aroma. Formulators should be aware of its moderate volatility and potential for degradation under extreme conditions.

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.
