FlavScents AInsights Entry: Eugenol (CAS: 97-53-0)

1. Identity & Chemical Information

Common Name(s): Eugenol
IUPAC Name: 4-Allyl-2-methoxyphenol
CAS Number: 97-53-0
FEMA Number: 2467
Other Identifiers: FL No. 02.013
Molecular Formula: C10H12O2
Molecular Weight: 164.20 g/mol

Eugenol is a phenolic compound characterized by an allyl chain and a methoxy group attached to a benzene ring. Its structure contributes to its distinctive spicy, clove-like aroma, which is a key factor in its use in both flavor and fragrance applications.

Citation hooks: FlavScents; PubChem; FEMA

2. Sensory Profile

Eugenol is renowned for its warm, spicy, and clove-like odor, with a sweet, woody undertone. It is a potent compound with a strong diffusion and is often used as an impact note in formulations. The odor threshold of eugenol is relatively low, making it effective even at minimal concentrations. In flavor applications, it imparts a spicy, clove-like taste, enhancing the complexity of the flavor profile.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Eugenol is naturally found in several essential oils, most notably clove oil, where it can constitute up to 85% of the oil. It is also present in cinnamon, nutmeg, and basil. The compound is biosynthesized in plants through the shikimic acid pathway, which is common for phenolic compounds. Its presence in natural sources qualifies it for "natural flavor" or "natural fragrance" designations under various regulatory frameworks.

4. Use in Flavors

Eugenol is widely used in flavor formulations, particularly in spice blends, confectionery, and beverages. It serves as a key component in clove, cinnamon, and allspice flavors. Typical use levels in finished products range from 5 to 150 ppm, depending on the desired intensity and product type. Eugenol is stable under heat but can oxidize over time, which may affect its flavor profile.

5. Use in Fragrances

In perfumery, eugenol is a versatile ingredient used across various fragrance families, including oriental, spicy, and woody compositions. It acts as a modifier and impact note, providing warmth and depth. Typical concentrations in fragrance formulations range from trace amounts to 1%, depending on the desired effect. Eugenol contributes primarily to the middle notes due to its moderate volatility.

6. Regulatory Status (Regional Overview)

United States

Eugenol is generally recognized as safe (GRAS) for use in food by FEMA. It is also approved for use in cosmetics and fragrances.

European Union

Eugenol is listed under Regulation (EC) No 1334/2008 and has an assigned FL number. It is subject to specific concentration limits in cosmetic products due to potential sensitization.

United Kingdom

Post-Brexit, the UK aligns with EU regulations regarding eugenol use in flavors and fragrances.

Asia

In Japan and China, eugenol is permitted for use in food and cosmetics, with specific guidelines on concentration levels.

Latin America

Eugenol is approved for use in flavors and fragrances, with regulations similar to those in the US and EU.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Oral Exposure

Eugenol has an acceptable daily intake (ADI) established by JECFA. It is considered safe for consumption at typical use levels in food.

Dermal Exposure

Eugenol can cause skin sensitization and irritation at higher concentrations. IFRA provides guidelines on its use in fragrances to minimize these risks.

Inhalation Exposure

While eugenol is volatile, inhalation exposure in occupational settings is generally low. Proper ventilation and handling practices are recommended.

Risk profiles differ slightly between food and fragrance applications, primarily due to the potential for dermal sensitization in the latter.

Citation hooks: EFSA; FEMA; PubChem; toxicology literature

8. Practical Insights for Formulators

Eugenol is valued for its ability to impart a warm, spicy character to both flavors and fragrances. It synergizes well with other spice and woody notes, enhancing complexity. Formulators should be cautious of its strong impact, which can easily dominate a blend if overused. It is often under-utilized in floral compositions, where it can add depth and warmth.

9. Confidence & Data Quality Notes

The data on eugenol is well-established, with comprehensive documentation available from authoritative sources. Industry practices are well-documented, though some variability exists in concentration limits across regions. Known data gaps are minimal, primarily related to long-term exposure effects.

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.
