2. Sensory Profile

11-Dodecenoic acid is noted for its mild, fatty odor with a hint of waxy and slightly floral nuances. Its sensory characteristics make it suitable as a background note in complex formulations, providing subtlety and depth. The odor intensity is moderate, and it is typically used to enhance the realism of fatty or creamy profiles in both flavors and fragrances. Specific taste and odor thresholds are not well-documented, but it is generally used in low concentrations to avoid overpowering other components.

3. Natural Occurrence & Formation

11-Dodecenoic acid is not commonly found in nature as a standalone compound but can be a component of certain natural fats and oils. It may form through the enzymatic degradation of longer-chain fatty acids or through synthetic processes in industrial settings. Its presence in natural products is often associated with the broader category of unsaturated fatty acids, which are integral to various biological functions and contribute to the "natural flavor" designation when derived from natural sources.

4. Use in Flavors

In flavor applications, 11-dodecenoic acid is utilized primarily in dairy, creamy, and fatty flavor profiles. It acts as a background realism enhancer, providing a subtle fatty note that complements other flavor components. Typical use levels in finished food products range from 0.1 to 5 ppm, with higher concentrations potentially leading to an undesirable waxy taste. Its stability is generally good under typical food processing conditions, though it may be susceptible to oxidation if not properly protected.

5. Use in Fragrances

11-Dodecenoic acid is used in fragrance formulations to impart a subtle fatty and waxy note, often enhancing the richness and depth of floral and creamy accords. It is typically found in trace amounts, contributing to the base notes of a fragrance composition. Its volatility is low, making it more suitable for long-lasting fragrance effects. The compound is often used in personal care products and fine fragrances where a natural, creamy undertone is desired.

7. Toxicology, Safety & Exposure Considerations

For oral exposure, 11-dodecenoic acid is generally considered safe at low concentrations typical of flavor use, though specific ADI or MSDI values are not available. Dermal exposure in fragrance applications is unlikely to cause irritation or sensitization at typical use levels, 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 in place to prevent excessive exposure during manufacturing.

8. Practical Insights for Formulators

11-Dodecenoic acid is valued for its ability to enhance creamy and fatty notes without dominating the overall profile. It synergizes well with other fatty acids and esters, providing a natural richness. Formulators should be cautious of its potential to impart a waxy note if used in excess. It is often under-utilized in formulations seeking a subtle, natural fatty character.

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.
