Ethyl pentadecanoate is an ester formed from pentadecanoic acid and ethanol. Its structure consists of a long carbon chain, which contributes to its hydrophobic nature and influences its odor profile. The ester functional group is crucial for its characteristic scent, often described as waxy or fruity.

2. Sensory Profile

Ethyl pentadecanoate is known for its mild, waxy, and slightly fruity odor. It is often used to impart a subtle, creamy note in formulations. The intensity of its scent is moderate, making it suitable for use as a background note rather than a primary impact odor. 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

Ethyl pentadecanoate is not commonly found in nature but can be synthesized through esterification of pentadecanoic acid with ethanol. This reaction is typically catalyzed by an acid or enzyme. While it is not a primary component of natural flavors or fragrances, it can be used in formulations labeled as "natural" if derived from natural sources.

4. Use in Flavors

Ethyl pentadecanoate is used in various flavor applications, particularly in dairy and fruity profiles. It acts as a modifier, enhancing creaminess and adding depth to the flavor profile. Typical use levels in finished food products range from 1 to 10 ppm, with higher concentrations potentially leading to an undesirable waxy taste. It is relatively stable under normal processing conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

In fragrances, ethyl pentadecanoate is utilized for its ability to impart a soft, waxy note. It is commonly found in floral and fruity fragrance families, where it serves as a background note to enhance the overall complexity. Typical concentration ranges in fragrance formulations are from 0.1% to 1%, depending on the desired intensity. It contributes primarily to the base note due to its low volatility.

7. Toxicology, Safety & Exposure Considerations

Ethyl pentadecanoate is considered safe for use in food and fragrance applications at typical use levels. Oral exposure through flavor use is minimal, with no specific ADI or MSDI established. Dermal exposure in fragrances is generally low risk, with no significant irritation or sensitization reported. Inhalation exposure is minimal due to its low volatility. Overall, the risk profile does not significantly differ between food and fragrance applications.

8. Practical Insights for Formulators

Ethyl pentadecanoate is valued for its ability to enhance creaminess and add subtle complexity to both flavors and fragrances. It synergizes well with other esters and can help smooth out harsh notes. Formulators should be cautious of overuse, which can lead to a waxy or soapy character. It is often under-utilized in formulations seeking a natural profile enhancement.

9. Confidence & Data Quality Notes

The data on ethyl pentadecanoate is well-established for its sensory characteristics and typical use levels. However, specific regulatory approvals and toxicological data are less documented, relying on general safety assumptions. Industry practices provide guidance on its effective use, though some undocumented practices may exist.

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.
