FlavScents AInsights Entry for Lauric Acid (CAS: 143-07-7)

1. Identity & Chemical Information

Lauric Acid, also known as dodecanoic acid, is a saturated fatty acid with the molecular formula C12H24O2 and a molecular weight of 200.32 g/mol. It is identified by the CAS number 143-07-7 and has a FEMA number of 2611. Lauric Acid is characterized by a long carbon chain with a carboxylic acid functional group, which contributes to its fatty, waxy odor profile. This structure is significant in its role as a precursor in the synthesis of various esters used in flavor and fragrance applications.

2. Sensory Profile

Lauric Acid is known for its mild, creamy, and slightly soapy odor, often described as having a waxy, fatty character. It is not typically used for its flavor but rather as a precursor to more volatile esters that impart coconut-like aromas. The sensory threshold for Lauric Acid is relatively high, meaning it requires a significant concentration to be perceptible. Its primary role in formulations is as a background note that enhances the richness and depth of other flavors.

3. Natural Occurrence & Formation

Lauric Acid is naturally found in various plant and animal fats, with coconut oil and palm kernel oil being particularly rich sources. It is biosynthesized in nature through the fatty acid synthesis pathway, where acetyl-CoA is elongated to form the 12-carbon chain. Lauric Acid's presence in natural oils makes it a candidate for "natural flavor" designation when derived from these sources.

4. Use in Flavors

In flavor applications, Lauric Acid itself is not commonly used due to its high sensory threshold and limited flavor profile. However, it serves as a precursor for the synthesis of esters like ethyl laurate, which are used to impart coconut and tropical fruit notes. Typical use levels of Lauric Acid-derived esters in finished food products range from 10 to 100 ppm, depending on the desired intensity and product type. Lauric Acid is stable under typical food processing conditions, including moderate heat and neutral pH.

5. Use in Fragrances

Lauric Acid is utilized in fragrance formulations primarily as a precursor to more volatile compounds. It contributes to the base notes of a fragrance, providing a creamy, fatty undertone that enhances the longevity and depth of the scent. It is used in concentrations ranging from trace amounts to several percent, depending on the desired effect and product type. Its low volatility makes it suitable for use in products where a long-lasting scent is desired.

6. Regulatory Status (Regional Overview)

In the United States, Lauric Acid 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. Post-Brexit, the United Kingdom aligns with EU regulations for Lauric Acid. 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 recognize Lauric Acid's safety in food and fragrance applications.

7. Toxicology, Safety & Exposure Considerations

Lauric Acid is considered safe for oral exposure, with an acceptable daily intake (ADI) not specifically established but generally recognized as safe due to its natural occurrence in foods. Dermal exposure is also deemed safe, with low potential for irritation or sensitization, making it suitable for use in cosmetics and personal care products. Inhalation exposure is minimal due to its low volatility, reducing occupational hazards. The risk profiles for food and fragrance applications are similar, with no significant differences noted.

8. Practical Insights for Formulators

Lauric Acid is valued for its role as a precursor in the synthesis of esters that provide desirable sensory attributes. It synergizes well with other fatty acids and esters to create rich, creamy profiles. Formulators should be cautious of its high sensory threshold, ensuring it is used in conjunction with more potent compounds. It is often under-utilized in its pure form but is essential in creating complex, long-lasting flavors and fragrances.

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.
