FlavScents AInsights Entry for Dipentene (CAS: 138-86-3)

1. Identity & Chemical Information

Common Name(s): Dipentene, Limonene
IUPAC Name: 1-Methyl-4-(1-methylethenyl)cyclohexene
CAS Number: 138-86-3
FEMA Number: 2633
Other Identifiers: FL No. 02.060, CoE No. 113
Molecular Formula: C10H16
Molecular Weight: 136.24 g/mol

Dipentene, commonly known as limonene, is a monocyclic monoterpene with a characteristic citrus odor. Its structure comprises a cyclohexene ring with an isopropenyl group, contributing to its distinctive scent. The presence of the double bond in the isopropenyl group is crucial for its reactivity and odor profile.

Citation hooks: FlavScents; PubChem; FEMA

2. Sensory Profile

Dipentene is renowned for its fresh, citrus-like aroma, often described as sweet and lemony. It exhibits a moderate to high intensity with excellent diffusion properties, making it a popular choice for imparting a bright, uplifting character in both flavors and fragrances. The odor threshold for dipentene is relatively low, enhancing its effectiveness as an impact note in formulations.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Dipentene is naturally found in the oils of citrus fruits, particularly in the peels of oranges and lemons. It is also present in other essential oils such as peppermint and pine. The compound is biosynthesized in plants through the mevalonate pathway, a key route for the formation of terpenes. Its natural occurrence in citrus oils makes it a candidate for "natural flavor" or "natural fragrance" designations.

Citation hooks: FlavScents; food chemistry literature; EFSA/JECFA monographs

4. Use in Flavors

Dipentene is extensively used in flavor formulations, particularly in citrus-flavored products such as beverages, candies, and baked goods. It serves as a primary impact note, providing a fresh, zesty character. Typical use levels in finished products range from 10 to 100 ppm, with higher concentrations potentially leading to overpowering effects. Dipentene is relatively stable under acidic conditions but may oxidize upon prolonged exposure to air.

Citation hooks: FlavScents; FEMA GRAS documentation; formulation literature

5. Use in Fragrances

In perfumery, dipentene is utilized across various fragrance families, including citrus, fougère, and chypre. It acts as a top note, offering a bright, invigorating quality. Concentration ranges in fragrance formulations typically vary from 0.1% to 1%, depending on the desired intensity and product type. Its volatility ensures a quick release, contributing to the initial impression of a fragrance.

Citation hooks: FlavScents; IFRA; fragrance chemistry texts

6. Regulatory Status (Regional Overview)

United States: Recognized as GRAS by FEMA for flavor use.
European Union: Approved under Regulation (EC) No 1334/2008 with FL No. 02.060.
United Kingdom: Follows EU regulations post-Brexit.
Asia: Approved for use in Japan and China, with specific concentration limits.
Latin America: Generally accepted in Brazil and MERCOSUR countries, subject to local regulations.

Dipentene's regulatory status is well-established, with harmonized approvals across major regions. However, formulators should verify specific concentration limits and usage conditions in each market.

7. Toxicology, Safety & Exposure Considerations

Dipentene is considered safe for use in food and fragrance applications, with a high margin of safety. Oral exposure through flavor use is supported by an ADI established by JECFA. Dermal exposure in fragrances is generally well-tolerated, though it may cause mild irritation in sensitive individuals. Inhalation exposure is minimal due to its rapid evaporation. Overall, dipentene's risk profile is favorable, with no significant differences between food and fragrance applications.

8. Practical Insights for Formulators

Dipentene is valued for its versatility and ability to enhance freshness in both flavors and fragrances. It synergizes well with other citrus and herbal notes, providing a natural lift. Formulators should be cautious of its potential to dominate blends if used excessively. It is often under-utilized in non-citrus applications, where it can add unexpected brightness.

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.
