AInsights Entry for Terpinolene (CAS: 586-62-9)

1. Identity & Chemical Information

Common Name(s): Terpinolene
IUPAC Name: 1-Methyl-4-(propan-2-ylidene)cyclohexene
CAS Number: 586-62-9
FEMA Number: 3044
Other Identifiers: FL No. 02.062
Molecular Formula: C10H16
Molecular Weight: 136.24 g/mol

Terpinolene is a monoterpene hydrocarbon characterized by a cyclohexene ring with a methyl and an isopropylidene group. Its structure contributes to its distinct odor profile, which is often described as fresh and pine-like with citrus and herbal nuances. The presence of the isopropylidene group is particularly relevant to its odor characteristics, providing a sharp, clean scent that is valued in both flavor and fragrance applications.

Citation hooks: FlavScents; PubChem; FEMA

2. Sensory Profile

Terpinolene is known for its fresh, piney aroma with citrus and herbal undertones. It is often described as having a moderate intensity and a clean, crisp character. The compound is used as an impact note in both flavor and fragrance formulations, providing a refreshing top note that enhances the overall sensory experience. While specific taste and odor thresholds are not widely documented, terpinolene is typically used in small concentrations due to its potent aroma.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Terpinolene naturally occurs in a variety of essential oils, including those from sage, rosemary, and conifers such as pine. It is also found in some citrus fruits. The compound is biosynthesized in plants via the mevalonate pathway, which is common for monoterpenes. Its presence in natural sources qualifies it for use in products labeled as containing "natural flavors" or "natural fragrances."

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

4. Use in Flavors

Terpinolene is utilized in flavor formulations for its fresh, piney, and citrus-like notes. It is commonly used in categories such as citrus, herbal, and spice flavors. In flavor systems, terpinolene acts as a modifier, enhancing the freshness and complexity of the blend. Typical use levels in finished food or beverage products range from 0.1 to 5 ppm, depending on the desired intensity and the specific application. Terpinolene is relatively stable under normal conditions but may degrade with prolonged exposure to heat and light.

5. Use in Fragrances

In fragrance applications, terpinolene is valued for its fresh, clean scent and is used in a variety of product types, including personal care products, household cleaners, and air fresheners. It contributes primarily to the top notes of a fragrance, providing an initial burst of freshness. Typical concentration ranges in fragrance formulations are from 0.1% to 1%, depending on the product type and desired effect. Terpinolene's volatility makes it suitable for top note applications, where it can quickly impart its characteristic scent.

Citation hooks: FlavScents; IFRA; fragrance chemistry texts

6. Regulatory Status (Regional Overview)

United States: Terpinolene is generally recognized as safe (GRAS) for use in food by FEMA.
European Union: Approved for use in food flavorings under Regulation (EC) No 1334/2008, with an assigned FL number.
United Kingdom: Regulatory status aligns with the EU post-Brexit.
Asia: In Japan and China, terpinolene is permitted for use in flavors, though specific regulations may vary.
Latin America: Generally accepted in MERCOSUR countries, but specific national regulations should be consulted.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Terpinolene is considered safe for use in food and fragrance applications at typical exposure levels. Oral exposure through flavor use is supported by its GRAS status, with no specific ADI or MSDI established, indicating low toxicity at typical use levels. Dermal exposure in fragrance applications is generally safe, though it may cause mild irritation in sensitive individuals. Inhalation exposure is not typically a concern due to its low volatility and use in low concentrations. Overall, terpinolene has a favorable safety profile, with no significant differences in risk between food and fragrance applications.

Citation hooks: EFSA; FEMA; PubChem; toxicology literature

8. Practical Insights for Formulators

Terpinolene is valued for its ability to impart a fresh, clean scent and flavor, making it a versatile component in both flavor and fragrance formulations. It synergizes well with other terpenes and citrus notes, enhancing the overall freshness and complexity of the blend. Formulators should be mindful of its potency and potential for oxidation, which can lead to off-notes if not properly stabilized. It is often under-used in formulations where a fresh, piney character is desired.

Citation hooks: FlavScents; industry practice

9. Confidence & Data Quality Notes

The data on terpinolene is well-established, with comprehensive information available from authoritative sources such as FEMA and EFSA. Industry practices are well-documented, though specific sensory thresholds and detailed toxicological data may be less readily available. Overall, the confidence in the data quality is high, with no significant gaps or ambiguities noted.

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.
