2. Sensory Profile

Muurola-4,11-diene is characterized by its woody, earthy, and slightly spicy aroma. It is often described as having a moderate intensity with a persistent diffusion. In flavor applications, it can impart a subtle, grounding note that enhances the complexity of the overall profile. The compound is typically used as a background realism note rather than a primary impact flavor.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Muurola-4,11-diene is naturally found in various essential oils, including those derived from certain coniferous trees and some species of the Asteraceae family. It is formed through the biosynthesis of sesquiterpenes in plants, often as a response to environmental stressors. Its presence in natural sources qualifies it for use in "natural flavor" and "natural fragrance" designations.

4. Use in Flavors

Muurola-4,11-diene is used in flavor formulations primarily within the savory and spice categories. It serves as a functional background note that enhances the authenticity and depth of flavors. Typical use levels in finished food products range from 0.1 to 5 ppm, depending on the desired intensity and the complexity of the flavor system. It is relatively stable under typical processing conditions but may degrade under extreme heat or oxidative environments.

5. Use in Fragrances

In fragrance applications, muurola-4,11-diene is valued for its contribution to woody and earthy fragrance families. It acts as a modifier and base note, providing depth and longevity to the fragrance composition. Typical concentration ranges in perfumes and personal care products are from 0.01% to 0.5%. Its volatility is moderate, contributing primarily to the middle and base notes of a fragrance.

6. Regulatory Status (Regional Overview)

United States: Not explicitly listed as FEMA GRAS; usage in flavors and fragrances is subject to general safety evaluations.
European Union: Not specifically listed under Regulation (EC) No 1334/2008; usage aligns with general safety and labeling requirements.
United Kingdom: Follows EU regulations post-Brexit with no significant divergence reported.
Asia: Limited specific data; general safety and usage guidelines apply.
Latin America: Usage is generally aligned with international safety standards, though specific regulatory data is limited.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Data not found for specific ADI or MSDI values; general safety practices suggest low-level use in flavor applications.
Dermal Exposure: No specific IFRA restrictions; considered non-irritating and non-sensitizing at typical use levels.
Inhalation Exposure: Moderate volatility suggests minimal occupational exposure risk under normal use conditions.

Risk profiles do not significantly differ between food and fragrance applications, though exposure routes and concentrations vary.

8. Practical Insights for Formulators

Muurola-4,11-diene is valued for its ability to enhance the complexity and authenticity of both flavors and fragrances. It synergizes well with other woody and spicy notes, providing a grounding effect. Formulators should be cautious of overuse, which can lead to an overpowering earthy character. It is often underutilized in formulations seeking a subtle, natural enhancement.

9. Confidence & Data Quality Notes

The data on muurola-4,11-diene is well-established in terms of its sensory profile and natural occurrence. However, specific regulatory and toxicological data are less documented, requiring formulators to rely on industry-typical practices and general safety guidelines.

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.
