FlavScents AInsights Entry: 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. Lauric Acid is recognized by FEMA with the number 2621. This compound is characterized by a long carbon chain with a carboxylic acid group, which contributes to its fatty, waxy odor profile. The structure-odor relationship is significant as the saturated nature of the carbon chain influences its sensory characteristics and functional applications in both flavors and fragrances.

2. Sensory Profile

Lauric Acid is known for its mild, creamy, and slightly soapy odor, often described as fatty and waxy. It has a low odor threshold, making it a subtle yet impactful component in formulations. In flavor applications, it provides a creamy, coconut-like taste, contributing to the richness and mouthfeel of the product. Its sensory role is typically as a background note, enhancing the overall realism and depth of the flavor profile.

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 also present in human breast milk. The formation of Lauric Acid in nature occurs through the biosynthesis of fatty acids, where acetyl-CoA is elongated to form the 12-carbon chain. Its presence in natural sources qualifies it for use in "natural flavor" and "natural fragrance" designations, aligning with consumer preferences for naturally derived ingredients.

4. Use in Flavors

Lauric Acid is utilized in a variety of flavor categories, including dairy, confectionery, and bakery products. It functions primarily as a creamy, coconut-like flavor enhancer. Typical use levels in finished food products range from 10 to 100 ppm, with industry-typical concentrations often around 50 ppm. Lauric Acid is stable under typical processing conditions, but care should be taken to avoid oxidation, which can lead to off-flavors.

5. Use in Fragrances

In fragrance applications, Lauric Acid is used in soap and detergent formulations, contributing to the creamy, fatty notes that enhance the overall scent profile. It is commonly found in fragrance families such as gourmand and oriental. Typical concentration ranges in fragrance products are from 0.1% to 1%, depending on the desired intensity and product type. Lauric Acid contributes primarily to the base notes due to its low volatility.

6. Regulatory Status (Regional Overview)

In the United States, Lauric Acid is recognized as GRAS (Generally Recognized As Safe) by FEMA for flavor use. 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, Lauric Acid is approved for use in Japan and China, with specific guidelines varying by country. In Latin America, countries like Brazil and those in MERCOSUR have harmonized regulations for its use in food and fragrance products.

7. Toxicology, Safety & Exposure Considerations

Lauric Acid is considered safe for oral exposure in flavor applications, with an acceptable daily intake (ADI) not specifically established but generally recognized as safe at typical use levels. For dermal exposure in fragrance applications, it is not known to cause irritation or sensitization, aligning with IFRA guidelines. Inhalation exposure is minimal due to its low volatility, reducing occupational risks. The risk profiles for food and fragrance applications are similar, with no significant safety concerns reported.

8. Practical Insights for Formulators

Lauric Acid is valued for its ability to impart creamy, coconut-like notes, enhancing the richness of both flavors and fragrances. It synergizes well with other fatty acids and esters, providing a balanced profile. Formulators should be cautious of oxidation, which can lead to undesirable off-notes. It is often under-used in formulations where a subtle, creamy background note 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.
