4. Use in Flavors

In the flavor industry, geranyl butyrate is used to impart fruity and floral notes to a variety of products, including beverages, confectionery, and baked goods. It is particularly effective in enhancing citrus, berry, and tropical fruit flavors. The typical use levels in finished food products range from 1 to 10 ppm, with higher concentrations potentially leading to overpowering effects. Stability considerations include its moderate resistance to heat and pH variations, although it may be susceptible to oxidation over time.

6. Regulatory Status (Regional Overview)

In the United States, geranyl butyrate 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, countries like Japan and China have specific guidelines for its use in flavors and fragrances, often aligning with international standards. In Latin America, regulatory frameworks such as those in Brazil and MERCOSUR also recognize its safe use within specified limits.

7. Toxicology, Safety & Exposure Considerations

Geranyl butyrate is considered safe for use in flavors and fragrances when used within recommended limits. Oral exposure through flavor use is supported by an acceptable daily intake (ADI) established by regulatory bodies, although specific values may not be clearly reported. Dermal exposure in fragrance applications is generally low-risk, with minimal reports of irritation or sensitization. Inhalation exposure is primarily relevant in occupational settings, where adequate ventilation and protective measures are advised. The risk profiles for food and fragrance applications are similar, with no significant differences noted.

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.
