3. Natural Occurrence & Formation

Geranyl isobutyrate is not commonly found in nature but can be synthesized through esterification processes involving geraniol and isobutyric acid. It is not typically associated with natural flavor or fragrance designations due to its synthetic origin. However, its components, such as geraniol, are naturally occurring in various essential oils, including rose and citronella.

4. Use in Flavors

In the flavor industry, geranyl isobutyrate is utilized in a variety of applications, including fruit flavors, especially pear, apple, and citrus. It serves as a functional component that enhances the overall flavor profile by adding depth and complexity. Typical use levels in finished food or beverage products range from 1 to 10 ppm, with higher concentrations potentially leading to overpowering effects. It is generally stable under typical food processing conditions, though it may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

Geranyl isobutyrate is employed in the fragrance industry across several fragrance families, including floral, fruity, and citrus. It acts as a modifier or impact note, contributing to the top and middle notes of a fragrance composition. Its volatility is moderate, allowing it to blend well with other fragrance components. Typical concentration ranges in fragrance formulations are from 0.1% to 1%, depending on the desired intensity and product type.

6. Regulatory Status (Regional Overview)

In the United States, geranyl isobutyrate 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. Post-Brexit, the United Kingdom aligns with EU regulations, though specific divergences may occur. In Asia, including Japan and China, it is generally accepted for use in flavors and fragrances, but specific regulatory details should be verified. In Latin America, countries like Brazil follow MERCOSUR guidelines, which typically harmonize with international standards.

7. Toxicology, Safety & Exposure Considerations

Geranyl isobutyrate is considered safe for use in flavors and fragrances within established limits. For oral exposure, it has a high margin of safety, with no specific ADI or MSDI reported, but it is used at low concentrations. Dermal exposure in fragrances is generally safe, with low potential for irritation or sensitization, though IFRA guidelines should be consulted for specific product types. Inhalation exposure is minimal due to its moderate volatility, but occupational safety measures should be observed in manufacturing settings.

8. Practical Insights for Formulators

Geranyl isobutyrate is valued for its ability to impart a fresh, fruity, and floral character to both flavors and fragrances. It synergizes well with other esters and terpenes, enhancing the overall profile of a formulation. Common pitfalls include overuse, which can lead to an overpowering scent or flavor, and instability under extreme conditions. It is often under-used in complex formulations where its subtlety can enhance the overall sensory experience.

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.
