5. Use in Fragrances

In fragrance formulations, trans-tetradec-4-enal is valued for its ability to impart a fresh, green character. It is used in various fragrance families, including green, floral, and marine scents. Its role can range from a trace realism enhancer to a prominent impact note. Typical concentration ranges are from 0.01% to 0.5% in the final product, contributing primarily to the top and middle notes due to its moderate volatility.

6. Regulatory Status (Regional Overview)

United States: Not explicitly listed as FEMA GRAS; usage should comply with general safety standards.
European Union: Not specifically listed under Regulation (EC) No 1334/2008; assumed safe under general flavoring guidelines.
United Kingdom: Follows EU regulations post-Brexit with no significant divergence reported.
Asia: Limited specific data; generally follows international safety standards.
Latin America: Data not found; typically aligns with international norms.

Explicit approvals are limited, and harmonized assumptions are generally applied. Formulators should verify compliance with local regulations.

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Data not found for specific ADI or MSDI values. General safety is assumed based on typical use levels in flavors.
Dermal Exposure: Limited data on irritation or sensitization; formulators should refer to IFRA guidelines for safe use in fragrances.
Inhalation Exposure: Volatility suggests potential for inhalation exposure; occupational safety measures should be considered.

Risk profiles may differ between food and fragrance applications, with fragrance use requiring more stringent dermal 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.
