FlavScents AInsights Entry: Camphene (CAS: 79-92-5)

1. Identity & Chemical Information

Camphene is a bicyclic monoterpene with the IUPAC name 2,2-dimethyl-3-methylenebicyclo[2.2.1]heptane. It is identified by the CAS number 79-92-5. While it does not have a FEMA number, it is recognized in various chemical databases. The molecular formula of camphene is C10H16, and it has a molecular weight of 136.24 g/mol. The structure of camphene includes a bicyclic framework with a methylene bridge, contributing to its characteristic odor profile. The presence of the isopropylidene group is significant for its odor characteristics, which are often described as sharp and pungent.

Citation hooks: FlavScents; PubChem; FEMA

2. Sensory Profile

Camphene is known for its sharp, pungent, and somewhat woody odor, reminiscent of fir needles and turpentine. It is less commonly used for its flavor profile, which can be described as slightly bitter and cooling. The intensity of camphene's odor is moderate, and it is typically used as a background note or modifier in fragrance compositions. The odor threshold of camphene is not well-documented, but its sensory impact is significant enough to be noticeable at low concentrations.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Camphene occurs naturally in a variety of essential oils, including those from coniferous trees such as fir and pine. It is also found in small quantities in the oils of rosemary and sage. Camphene is biosynthesized in plants via the mevalonate pathway, where it is derived from geranyl pyrophosphate. Its presence in essential oils contributes to the "natural fragrance" designation of these materials.

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

4. Use in Flavors

In flavor applications, camphene is used sparingly due to its intense and somewhat harsh profile. It can be found in minty or herbal flavor compositions, where it serves as a modifier to enhance freshness. Typical use levels in food and beverages are low, often below 10 ppm, to avoid overpowering other flavor notes. Camphene is relatively stable under normal conditions but may degrade under high heat or acidic conditions, which can alter its sensory characteristics.

5. Use in Fragrances

Camphene is more prominently used in fragrance formulations, particularly in the creation of pine, herbal, and woody accords. It acts as a top note, providing a fresh and clean opening to fragrance compositions. Typical concentration ranges in perfumes are from trace amounts up to 1%, depending on the desired intensity and character. Its volatility makes it suitable for top note applications, where it can quickly impart its characteristic scent before evaporating.

6. Regulatory Status (Regional Overview)

In the United States, camphene is not specifically listed as a FEMA GRAS substance but is generally recognized as safe when used in accordance with good manufacturing practices. In the European Union, camphene is regulated under Regulation (EC) No 1334/2008, where it is permitted in flavorings. The UK follows similar regulations post-Brexit. In Asia, including Japan and China, camphene is used in flavors and fragrances with no specific restrictions noted. In Latin America, regulations are aligned with international standards, allowing its use in both flavors and fragrances.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Camphene's safety profile indicates low toxicity when used in typical concentrations for flavors and fragrances. Oral exposure studies suggest a low risk, with no specific ADI established. Dermal exposure in fragrance applications shows low irritation potential, but sensitization data is limited, warranting caution in formulations. Inhalation exposure is generally safe at typical fragrance concentrations, though occupational exposure should be monitored to prevent respiratory irritation.

Citation hooks: EFSA; FEMA; PubChem; toxicology literature

8. Practical Insights for Formulators

Camphene is valued for its ability to impart freshness and enhance herbal and woody notes in both flavors and fragrances. It synergizes well with other terpenes and can be used to add complexity to minty or pine-like profiles. Formulators should be cautious of its intensity, as overuse can lead to harshness. It is often underutilized in flavor applications due to its strong profile but can be effective in small doses.

9. Confidence & Data Quality Notes

The data on camphene is well-established in terms of its chemical identity and sensory characteristics. However, there are gaps in specific toxicological thresholds and regulatory nuances across different regions. Industry practices often rely on empirical knowledge due to limited formal 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.
