2. Sensory Profile

1-Dodecanol is known for its mild, waxy odor with a faint floral nuance. It is not typically used for its odor in isolation but can contribute to the overall sensory profile of a formulation by providing a subtle background note. The compound has a relatively high odor threshold, meaning it is not easily detected at low concentrations. Its primary role in sensory applications is as a modifier or a base note that can enhance the richness and depth of a fragrance or flavor composition.

3. Natural Occurrence & Formation

1-Dodecanol is naturally found in various plant and animal sources, including coconut oil and palm kernel oil, where it occurs as part of the fatty acid esters. It can also be produced synthetically through the hydrogenation of lauric acid or via the Ziegler process, which involves the oligomerization of ethylene followed by oxidation and reduction. Its presence in natural sources allows it to be designated as a "natural" ingredient in certain flavor and fragrance applications, depending on the extraction and processing methods used.

4. Use in Flavors

In flavor applications, 1-dodecanol is used primarily as a modifier to enhance the creamy and fatty notes in dairy and coconut flavors. It is typically employed at low concentrations, often in the range of 1-10 ppm, to avoid overpowering the desired flavor profile. The compound is stable under typical food processing conditions, including moderate heat and neutral pH, but may oxidize under prolonged exposure to air. Its use is generally limited to applications where a subtle enhancement of mouthfeel and richness is desired.

5. Use in Fragrances

1-Dodecanol is utilized in fragrance formulations as a base note that provides a waxy, creamy character. It is commonly found in personal care products, such as lotions and creams, where it contributes to the overall texture and longevity of the fragrance. Typical concentration ranges in fragrances are from 0.1% to 1%, depending on the desired effect and product type. Due to its low volatility, 1-dodecanol primarily contributes to the base of a fragrance, providing lasting power and depth.

6. Regulatory Status (Regional Overview)

In the United States, 1-dodecanol is generally recognized as safe (GRAS) for use in food by the FDA and FEMA. In the European Union, it is regulated under Regulation (EC) No 1334/2008 and has an assigned FL number. The United Kingdom follows similar regulations post-Brexit. In Asia, countries like Japan and China have specific guidelines for its use in food and cosmetics, often aligning with international standards. In Latin America, regulatory frameworks such as those in Brazil and MERCOSUR also recognize its use, with specific concentration limits in certain applications.

7. Toxicology, Safety & Exposure Considerations

1-Dodecanol is considered safe for use in both food and fragrance applications when used within recommended limits. For oral exposure, it has a high margin of safety due to its low toxicity. Dermal exposure is generally well-tolerated, with low potential for irritation or sensitization, making it suitable for use in personal care products. Inhalation exposure is minimal due to its low volatility, reducing occupational hazards. Overall, the risk profiles for food and fragrance applications are similar, with no significant safety concerns reported.

8. Practical Insights for Formulators

1-Dodecanol is valued for its ability to enhance the texture and richness of both flavors and fragrances. It synergizes well with other fatty alcohols and esters, providing a smooth, creamy base. Formulators should be cautious of using it at high concentrations, as it can impart an undesirable waxy note. It is often under-used in formulations where a subtle enhancement of mouthfeel or fragrance longevity is needed, making it a versatile tool for experienced formulators.

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.
