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 does not have a FEMA number as it is not typically used as a flavoring agent in its pure form. The compound is characterized by a long hydrocarbon chain and a carboxylic acid group, which contribute to its low volatility and waxy texture. Its structure is significant in determining its odor profile, which is relatively mild and soapy.

2. Sensory Profile

Lauric acid is known for its mild, soapy odor with a slightly fatty undertone. It is not typically used for its flavor or fragrance properties in isolation but can contribute to the overall sensory profile of a product when used in combination with other compounds. The odor threshold of lauric acid is relatively high, meaning it requires a significant concentration to be perceptible. Its sensory role is often as a background note, providing a subtle fatty character that can enhance the realism of certain formulations.

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. Lauric acid can be formed through the hydrolysis of triglycerides, a process that occurs naturally in the body and can be replicated industrially. Its presence in natural sources allows it to be designated as a "natural" ingredient in flavor and fragrance formulations, depending on the extraction and processing methods used.

4. Use in Flavors

Lauric acid is not commonly used as a direct flavoring agent due to its relatively bland taste. However, it can be a component of flavor systems where its fatty character contributes to the mouthfeel and richness of the product. Typical use levels in food are not well-documented, but it is generally present at low concentrations, often below 10 ppm, as part of a complex mixture of fatty acids. Lauric acid is stable under typical food processing conditions, including heat and pH variations, which makes it a reliable component in flavor formulations.

5. Use in Fragrances

In fragrance applications, lauric acid is used to impart a subtle, creamy, and soapy note. It is often found in personal care products such as soaps and shampoos, where it contributes to the overall texture and feel of the product. Lauric acid is typically used at low concentrations, often less than 1%, due to its mild odor profile. It acts as a base note, providing longevity and depth to the fragrance composition.

6. Regulatory Status (Regional Overview)

In the United States, lauric acid is generally recognized as safe (GRAS) for use in food products. The European Union also permits its use under Regulation (EC) No 1334/2008, where it is listed with an FL number. In the United Kingdom, post-Brexit regulations align closely with EU standards. In Asia, countries like Japan and China allow its use in food and cosmetics, though specific regulations may vary. In Latin America, lauric acid is accepted in food and cosmetic applications, with Brazil and MERCOSUR countries following similar guidelines.

7. Toxicology, Safety & Exposure Considerations

Lauric acid is considered safe for oral exposure, with no specific acceptable daily intake (ADI) established due to its natural occurrence in foods. For dermal exposure, it is generally non-irritating and non-sensitizing, making it suitable for use in personal care products. Inhalation exposure is not typically a concern due to its low volatility. The risk profiles for food and fragrance applications are similar, with no significant safety concerns identified at typical use levels.

8. Practical Insights for Formulators

Lauric acid is valued for its ability to enhance the texture and mouthfeel of food products and to provide a creamy, soapy note in fragrances. It synergizes well with other fatty acids and esters, contributing to a balanced sensory profile. Formulators should be aware of its potential to dominate if used excessively, leading to an undesirable waxy or soapy character. It is often under-used in formulations where a subtle fatty note could enhance the overall profile.

9. Confidence & Data Quality Notes

The data on lauric acid is well-established, with extensive documentation in both scientific literature and industry practice. While specific use levels in flavors are not always clearly reported, industry-typical practices provide a reliable guide. Regulatory information is comprehensive, though formulators should verify specific regional requirements.

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.
