3. Natural Occurrence & Formation

• Known Natural Sources: Dihydromyrcene is not commonly found in nature but can be derived from the hydrogenation of myrcene, a naturally occurring terpene in essential oils such as bay, verbena, and lemongrass.
• Formation Pathways: It is primarily produced through synthetic processes involving the hydrogenation of myrcene.
• Relevance to “Natural Flavor” or “Natural Fragrance” Designation: As a synthetic derivative, dihydromyrcene may not qualify for natural labeling unless derived from natural myrcene sources.

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.
