FlavScents AInsights Entry for Grindelia Robusta Leaf Oil (CAS: 84696-17-3)

1. Identity & Chemical Information

Grindelia robusta leaf oil is a natural complex material derived from the leaves of the Grindelia robusta plant. It is commonly referred to as gumweed oil. The CAS number for this essential oil is 84696-17-3. As a complex natural material, it does not have a single IUPAC name or molecular formula. Instead, it is composed of various constituents that contribute to its overall properties and uses.

2. Sensory Profile

Grindelia robusta leaf oil is characterized by its balsamic, herbaceous, and slightly sweet aroma. The intensity of the odor is moderate, providing a warm and comforting scent profile. It is often used as a background realism note in fragrance compositions, adding depth and complexity. The oil's sensory role can vary from being an impact note to a subtle modifier, depending on the concentration used.

3. Natural Occurrence & Formation

Grindelia robusta is native to North America, particularly found in the western United States. The essential oil is extracted from the leaves of the plant, typically through steam distillation. The plant is known for its resinous exudate, which contributes to the oil's unique properties. As a natural product, it qualifies for "natural fragrance" designation under various regulatory frameworks.

4. Use in Flavors

Grindelia robusta leaf oil is not commonly used in flavor applications due to its strong and distinctive aroma. However, when used, it can contribute to herbal and balsamic flavor profiles. Typical use levels in food and beverages are low, often below 10 ppm, to avoid overpowering other flavor components. The oil is relatively stable under normal storage conditions but may degrade with prolonged exposure to heat and light.

5. Use in Fragrances

In the fragrance industry, Grindelia robusta leaf oil is valued for its warm, balsamic scent, fitting well within the woody and herbal fragrance families. It serves as a modifier or background note, enhancing the complexity of the fragrance. Typical concentration ranges in perfumes are from 0.1% to 1%, depending on the desired intensity. The oil contributes primarily to the middle notes of a fragrance composition.

6. Regulatory Status (Regional Overview)

In the United States, Grindelia robusta leaf oil is not specifically listed by FEMA as GRAS for flavor use, and its use in fragrances is subject to IFRA guidelines. In the European Union, it falls under the general regulations for natural flavoring substances (Reg. (EC) No 1334/2008). Post-Brexit, the UK aligns closely with EU regulations. In Asia and Latin America, regulatory status may vary, and local guidelines should be consulted.

7. Toxicology, Safety & Exposure Considerations

For oral exposure, data on the acceptable daily intake (ADI) or threshold of toxicological concern (TTC) for Grindelia robusta leaf oil is not clearly reported. Dermal exposure in fragrance applications should consider potential sensitization, although specific IFRA restrictions are not detailed. Inhalation exposure is generally considered safe at typical fragrance concentrations, but occupational exposure limits should be observed.

8. Practical Insights for Formulators

Grindelia robusta leaf oil is valued for its unique balsamic and herbaceous aroma, making it a versatile component in fragrance formulations. It blends well with other woody and herbal notes, providing depth and warmth. Formulators should be cautious of its intensity, as overuse can dominate a composition. It is often underutilized in flavor applications due to its strong aroma.

9. Confidence & Data Quality Notes

The data on Grindelia robusta leaf oil is well-established in terms of its sensory profile and typical uses in fragrances. However, there are gaps in toxicological data and specific regulatory approvals for flavor use. Industry practices often rely on historical usage and expert judgment in the absence of comprehensive documentation.

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.
