FlavScents AInsights Entry: Oleic Acid from Tall Oil Fatty Acids

1. Identity & Chemical Information

Common Name(s): Oleic Acid from Tall Oil Fatty Acids
IUPAC Name: (9Z)-Octadec-9-enoic acid
CAS Number: N/A
FEMA Number: Not applicable
Other Identifiers: Not applicable
Molecular Formula: C18H34O2
Molecular Weight: 282.46 g/mol
Functional Groups and Structure–Odor Relevance: Oleic acid is a monounsaturated omega-9 fatty acid. Its structure includes a long hydrocarbon chain with a single cis double bond, which influences its physical properties and potential odor characteristics, although it is generally considered odorless in its pure form.

2. Sensory Profile

Oleic acid itself is typically odorless and tasteless, but when derived from tall oil fatty acids, it may carry slight nuances depending on impurities or accompanying compounds. In formulations, it does not contribute significantly to the sensory profile but may influence the texture or mouthfeel of a product.

3. Natural Occurrence & Formation

Oleic acid is naturally found in various animal and vegetable fats and oils. Tall oil fatty acids are by-products of the wood pulping process, primarily from pine trees. The formation of oleic acid in this context involves the hydrolysis of triglycerides during the pulping process, followed by distillation to separate the fatty acids.

4. Use in Flavors

Oleic acid from tall oil fatty acids is not typically used for its flavor properties but may be included in formulations as a carrier or emulsifier. Its use levels in food are generally low, often below 100 ppm, primarily to aid in the dispersion of other flavor compounds. It is stable under typical food processing conditions, including moderate heat and pH variations.

5. Use in Fragrances

In fragrances, oleic acid from tall oil fatty acids may serve as a fixative or carrier, helping to stabilize volatile compounds. It is not a primary contributor to fragrance profiles but can enhance the longevity of more volatile notes. Typical concentrations are low, often less than 1% of the total formulation.

6. Regulatory Status (Regional Overview)

United States: Oleic acid is generally recognized as safe (GRAS) by the FDA for use in food.
European Union: Approved under Regulation (EC) No 1334/2008 for use in food flavorings.
United Kingdom: Follows EU regulations post-Brexit with no significant divergence reported.
Asia: Approved for use in food in Japan and China, with specific regulations varying by country.
Latin America: Generally accepted in food applications, with specific guidelines in Brazil and MERCOSUR countries.

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Oleic acid is considered safe for consumption with a high margin of safety. No specific ADI is established, but it is widely consumed as part of dietary fats.
Dermal Exposure: Generally non-irritating and non-sensitizing, making it suitable for use in topical applications.
Inhalation Exposure: Low volatility minimizes inhalation risks, but occupational exposure should still follow standard safety practices.

8. Practical Insights for Formulators

Oleic acid from tall oil fatty acids is valued for its emulsifying properties and ability to stabilize formulations. It synergizes well with other fatty acids and lipids. Formulators should be cautious of potential impurities that may affect the sensory profile or stability of the final product.

9. Confidence & Data Quality Notes

Data on oleic acid from tall oil fatty acids is well-established, with extensive documentation on its safety and regulatory status. However, specific sensory contributions are less documented due to its primary role as a carrier or stabilizer.

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.
