1. Identity & Chemical Information

• Common Name(s): Divanillin
• IUPAC Name: 4,4'-Methylenebis(2-methoxyphenol)
• CAS Number: 2092-49-1
• FEMA Number: Not available
• Other Identifiers: Not available
• Molecular Formula: C16H14O6

Divanillin is a dimeric form of vanillin, characterized by the presence of two methoxyphenol groups linked by a methylene bridge. This structure contributes to its unique sensory properties, which are distinct from those of vanillin itself. The methoxy and hydroxyl groups play a significant role in its odor profile, enhancing its sweet and creamy characteristics.

2. Sensory Profile

Divanillin is known for its sweet, creamy, and vanilla-like aroma, which is less intense but more rounded compared to vanillin. It provides a smooth, rich background note that can enhance the complexity of flavor and fragrance compositions. The odor intensity is moderate, making it suitable for use as a background realism enhancer rather than a primary impact note. Specific taste and odor thresholds for divanillin are not well-documented, but it is generally used in formulations where a subtle vanilla character is desired.

3. Natural Occurrence & Formation

Divanillin is not commonly found in nature but can be formed through the oxidative coupling of vanillin, a process that can occur during the aging of vanilla extracts or through specific enzymatic reactions. Its formation is relevant to the designation of "natural flavor" when derived from natural vanilla sources. However, synthetic production methods are also employed to ensure consistency and availability for commercial use.

4. Use in Flavors

Divanillin is primarily used in flavor applications to impart a creamy, vanilla-like note. It is commonly found in dairy, confectionery, and bakery products. Its functional role in flavor systems includes acting as a background enhancer and providing depth to vanilla profiles. Typical use levels in finished food products range from 1 to 10 ppm, with higher concentrations potentially leading to an overpowering effect. Divanillin is stable under typical processing conditions, including moderate heat and pH variations, but may degrade under extreme conditions.

5. Use in Fragrances

In fragrance applications, divanillin is valued for its ability to add creamy, sweet nuances to compositions. It is used across various fragrance families, including gourmand, oriental, and floral. Its role is often as a modifier or background note, contributing to the overall smoothness and richness of the fragrance. Typical concentration ranges in perfumes are from 0.1% to 1%, depending on the desired intensity. Divanillin contributes primarily to the middle and base notes due to its moderate volatility.

6. Regulatory Status (Regional Overview)

• United States: Divanillin does not have a specific FEMA GRAS status but is generally recognized as safe when used in accordance with good manufacturing practices.
• European Union: Not explicitly listed under Regulation (EC) No 1334/2008; use is subject to general safety assessments.
• United Kingdom: Follows EU regulations post-Brexit with no significant divergence reported.
• Asia: Limited specific regulatory information; generally follows international safety standards.
• Latin America: No specific regulations identified; typically aligns with international guidelines.

7. Toxicology, Safety & Exposure Considerations

Divanillin is considered safe for use in food and fragrance applications when used within recommended levels. Oral exposure through flavor use is generally low, with no specific ADI or MSDI established. Dermal exposure in fragrance applications is not associated with significant irritation or sensitization, but IFRA guidelines should be consulted for specific product types. Inhalation exposure is minimal due to its low volatility, but occupational safety measures should be observed during handling.

8. Practical Insights for Formulators

Divanillin is a valuable material for its ability to enhance vanilla profiles with a creamy, smooth character. It synergizes well with other vanilla derivatives and creamy notes, such as lactones. Formulators should be cautious of overuse, as excessive concentrations can lead to a cloying effect. It is often under-utilized in applications where a subtle vanilla enhancement is desired.

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.
