1. Identity & Chemical Information

Common Name(s): Cetyl Nonanoate
IUPAC Name: Hexadecyl nonanoate
CAS Number: 72934-15-7
FEMA Number: Not applicable
Other Identifiers: Not applicable
Molecular Formula: C25H50O2
Molecular Weight: 382.66 g/mol

Cetyl nonanoate is an ester formed from cetyl alcohol and nonanoic acid. It is characterized by its long carbon chain, which contributes to its emollient properties and low volatility. The ester functional group is crucial for its role in both flavor and fragrance applications, providing a smooth, waxy odor profile that can enhance the richness and depth of formulations.

2. Sensory Profile

Cetyl nonanoate is known for its subtle, waxy odor with a mild, fatty character. It is not typically used for its flavor or odor impact but rather as a modifier that enhances the overall sensory experience by adding a smooth, creamy texture. The compound's low volatility means it has a minimal diffusion rate, making it suitable for applications where a long-lasting effect is desired. Specific odor and taste thresholds are not well-documented, reflecting its primary use as a textural component rather than a direct sensory agent.

3. Natural Occurrence & Formation

Cetyl nonanoate is not commonly found in nature but can be synthesized through the esterification of cetyl alcohol and nonanoic acid. This synthetic pathway allows for precise control over purity and consistency, making it a reliable ingredient in both natural and synthetic formulations. While it does not occur naturally, its components are derived from natural sources, allowing it to be used in products labeled as "natural" under certain regulatory frameworks.

4. Use in Flavors

In flavor applications, cetyl nonanoate is primarily used as a textural agent rather than a flavoring compound. It can be found in various categories, including dairy, confectionery, and bakery products, where it contributes to a creamy mouthfeel. Typical use levels are not well-documented, but industry practice suggests concentrations in the range of 10-100 ppm, depending on the desired textural effect. Its stability under heat and acidic conditions makes it a versatile ingredient in processed foods.

5. Use in Fragrances

Cetyl nonanoate is utilized in fragrance formulations for its ability to impart a smooth, waxy base note. It is commonly found in personal care products, such as lotions and creams, where it enhances the longevity and richness of the fragrance. Typical concentration ranges are qualitative, with usage levels adjusted based on the desired effect and product type. Its low volatility classifies it as a base note, providing a lasting foundation for more volatile top and middle notes.

6. Regulatory Status (Regional Overview)

United States: Cetyl nonanoate is generally recognized as safe (GRAS) for use in food and cosmetics.
European Union: Approved under Regulation (EC) No 1334/2008 for use in food and cosmetics.
United Kingdom: Aligns with EU regulations post-Brexit, allowing its use in similar applications.
Asia: Approved for use in Japan and China, with specific concentration limits varying by product type.
Latin America: Recognized under MERCOSUR regulations, with usage guidelines similar to those in the EU.

Explicit approvals and harmonized assumptions are generally consistent across regions, though specific concentration limits may vary.

7. Toxicology, Safety & Exposure Considerations

Cetyl nonanoate is considered safe for use in both food and cosmetic applications. Oral exposure through flavor use is minimal, with no specific ADI or MSDI established, reflecting its low toxicity. Dermal exposure in fragrance applications is well-tolerated, with no significant reports of irritation or sensitization. Inhalation exposure is negligible due to its low volatility, minimizing occupational risks. Overall, the risk profile is consistent across food and fragrance applications, with a wide margin of safety.

8. Practical Insights for Formulators

Cetyl nonanoate is valued for its emollient properties, providing a smooth, creamy texture in both flavor and fragrance formulations. It synergizes well with other esters and alcohols, enhancing the richness and depth of the final product. Common pitfalls include overuse, which can lead to a greasy texture, and underuse, which may result in a lack of desired smoothness. It is frequently used in formulations where a long-lasting, subtle effect 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.
