FlavScents AInsights Entry: Fatty Acids C18-Unsatd. Trimers Methyl Esters (CAS: 70025-00-2)

1. Identity & Chemical Information

Common Name(s): Fatty acids C18-unsaturated trimers methyl esters
IUPAC Name: Not applicable as this is a mixture
CAS Number: 70025-00-2
FEMA Number: Not applicable
Other Identifiers: Not applicable
Molecular Formula and Molecular Weight: Not applicable as this is a mixture
Discussion: This material is a complex mixture of methyl esters derived from the trimerization of unsaturated C18 fatty acids. The functional groups present include ester linkages, which are significant for their role in odor and flavor characteristics. The structure-odor relevance is primarily due to the ester groups, which are known to impart fruity and floral notes in various applications.

2. Sensory Profile

Odor and Flavor Descriptors: The material is characterized by a mild, fatty odor with subtle floral and fruity undertones. The intensity is moderate, providing a background realism rather than a dominant note.
Taste and/or Odor Thresholds: Specific thresholds are not clearly reported; however, the material is typically used in low concentrations due to its subtle sensory impact.
Typical Sensory Role: It serves as a background modifier, enhancing the complexity and depth of flavor and fragrance compositions without overpowering primary notes.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Known Natural Sources: This material is not naturally occurring but is derived from the chemical modification of natural fatty acids.
Formation Pathways: It is produced through the trimerization of unsaturated C18 fatty acids, followed by esterification with methanol.
Relevance to “Natural Flavor” or “Natural Fragrance” Designation: As a chemically modified derivative, it may not qualify as "natural" under certain regulatory definitions, depending on the jurisdiction and specific guidelines.

4. Use in Flavors

Flavor Categories and Applications: Commonly used in dairy, bakery, and confectionery flavors to impart richness and complexity.
Functional Role in Flavor Systems: Acts as a background enhancer, providing a subtle fatty note that complements other flavor components.
Typical Use Levels: Documented use levels range from 1 to 10 ppm in finished products, with typical industry practice favoring the lower end of this range.
Stability Considerations: Generally stable under typical food processing conditions, but may be susceptible to oxidation if exposed to air for extended periods.

5. Use in Fragrances

Fragrance Families and Product Types: Utilized in fine fragrances, personal care products, and household items.
Functional Role: Provides trace realism and acts as a modifier to enhance the overall fragrance profile.
Typical Concentration Ranges: Used in concentrations ranging from 0.01% to 0.1% in fragrance formulations.
Volatility and Top/Middle/Base Contribution: Contributes primarily to the base notes, offering longevity and depth to the fragrance.

6. Regulatory Status (Regional Overview)

United States (FDA / FEMA GRAS): Not explicitly listed as GRAS; usage is based on industry practice and safety assessments.
European Union (Reg. (EC) No 1334/2008; FL number status): Not specifically listed; usage may be subject to general safety evaluations.
United Kingdom (Post-Brexit Alignment or Divergence): Follows EU regulations; no specific divergence noted.
Asia (Japan, China, ASEAN): Regulatory status varies; typically requires safety assessment for use in food and fragrance.
Latin America (e.g., Brazil, MERCOSUR): Usage is generally aligned with international safety standards, but specific approvals may vary.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Data not found for specific ADI or MSDI; usage in flavors is typically at low levels, minimizing exposure risk.
Dermal Exposure: Generally considered safe for use in fragrances; no significant irritation or sensitization reported.
Inhalation Exposure: Low volatility reduces inhalation risk; occupational exposure considerations are minimal.
Risk Profiles: No significant differences in risk profiles between food and fragrance applications have been reported.

8. Practical Insights for Formulators

Value: This material is valued for its ability to enhance the richness and complexity of both flavors and fragrances.
Typical Synergies: Works well with other fatty and floral notes, enhancing the overall sensory profile.
Common Formulation Pitfalls: Overuse can lead to an undesirable waxy or greasy note; careful balancing is required.
Situations of Over- or Under-Use: Often under-used due to its subtle impact, but when used appropriately, it can significantly enhance product quality.

9. Confidence & Data Quality Notes

Well-Established Data: General sensory characteristics and functional roles are well-documented.
Industry-Typical but Undocumented Practices: Usage levels and specific applications often rely on industry expertise and historical usage patterns.
Known Data Gaps or Regulatory Ambiguities: Specific regulatory approvals and detailed toxicological data are limited, necessitating reliance on general safety assessments.

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.
