2. Sensory Profile

Ethyl heptadecanoate is known for its mild, waxy, and fatty odor, often described as having a subtle fruity undertone. The intensity of its odor is generally low, making it suitable for use as a background note in formulations. It is not typically used for its taste, as its primary application is in fragrance rather than flavor. The sensory role of ethyl heptadecanoate is often as a modifier, providing a smooth, creamy base that enhances the overall profile of a fragrance or flavor system.

3. Natural Occurrence & Formation

Ethyl heptadecanoate is not commonly found in nature but can be synthesized through esterification of heptadecanoic acid with ethanol. This reaction is a typical method for producing esters, involving the condensation of an alcohol and an acid. While it is not a primary component of natural flavors or fragrances, its synthetic production allows it to be used in formulations that require a "natural" designation, provided the starting materials are derived from natural sources.

4. Use in Flavors

In flavor applications, ethyl heptadecanoate is used sparingly due to its low intensity and specific odor profile. It can be found in flavor categories such as dairy and creamy profiles, where it contributes to the richness and depth of the flavor. Typical use levels in finished food or beverage products are low, often in the range of 1-10 ppm, depending on the desired effect. It is stable under typical processing conditions, including moderate heat and pH variations, but may oxidize over time if not stored properly.

5. Use in Fragrances

Ethyl heptadecanoate is more commonly used in fragrance formulations, particularly in the creation of creamy, waxy, and fatty notes. It is found in fragrance families such as gourmand and oriental, where it serves as a base note, providing longevity and depth. Typical concentration ranges in fragrances are from 0.1% to 1%, depending on the desired intensity and role within the formulation. Its low volatility makes it suitable for use as a base note, contributing to the lasting power of the fragrance.

6. Regulatory Status (Regional Overview)

In the United States, ethyl heptadecanoate is generally recognized as safe (GRAS) for use in flavors, although specific regulatory documentation may be limited. In the European Union, it is subject to the regulations outlined in Reg. (EC) No 1334/2008, and it is included in the list of flavoring substances. The United Kingdom follows similar regulations post-Brexit. In Asia, including Japan and China, and in Latin America, such as Brazil, its use is generally accepted, but specific approvals may vary by country. It is important for formulators to verify compliance with local regulations.

7. Toxicology, Safety & Exposure Considerations

Ethyl heptadecanoate is considered safe for use in both flavor and fragrance applications, with no significant toxicological concerns reported at typical use levels. Oral exposure through flavor use is minimal, with no established acceptable daily intake (ADI) or threshold of toxicological concern (TTC) due to its low usage levels. Dermal exposure in fragrance applications is also considered safe, with no reports of irritation or sensitization. Inhalation exposure is minimal due to its low volatility, reducing occupational risks.

8. Practical Insights for Formulators

Ethyl heptadecanoate is valued for its ability to impart a creamy, waxy base note in both flavors and fragrances. It synergizes well with other esters and fatty acids, enhancing the richness of formulations. A common pitfall is overuse, which can lead to an undesirable waxy or fatty note. It is often under-used in formulations that could benefit from its subtle, creamy characteristics, particularly in dairy and gourmand profiles.

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.
