FlavScents AInsights Entry: Citronella Oil Java (CAS: 8000-29-1)
1. Identity & Chemical Information
Citronella oil Java, a natural complex material, is derived from the leaves of Cymbopogon winterianus. It is commonly referred to as Java citronella oil. The CAS number for this essential oil is 8000-29-1. It does not have a specific IUPAC name as it is not a single compound but a mixture of various constituents. The oil is recognized by FEMA with the number 2308. Other identifiers include its FL number 2260 and its CoE number 20. As a complex mixture, it does not have a single molecular formula or molecular weight. The oil's functional groups, primarily terpenes and alcohols, contribute to its characteristic lemony aroma, which is significant for its use in both flavor and fragrance applications.

2. Sensory Profile
Citronella oil Java is characterized by its fresh, lemony, and slightly woody aroma. The intensity of its scent is moderate to strong, with a high diffusion rate, making it a prominent top note in fragrance compositions. Its flavor profile is similarly citrusy, with a hint of sweetness and a slightly bitter undertone. The oil is often used as an impact note in both flavor and fragrance formulations, providing a bright, uplifting character. Specific odor and taste thresholds are not well-documented, but its strong aroma suggests a low threshold for sensory detection.

3. Natural Occurrence & Formation
Citronella oil Java is primarily obtained from the leaves of the Cymbopogon winterianus plant, which is cultivated in tropical regions such as Indonesia and India. The oil is extracted through steam distillation, a process that preserves its volatile aromatic compounds. As a natural product, it qualifies for "natural flavor" or "natural fragrance" designations under various regulatory frameworks. The composition of the oil can vary significantly depending on the geographical origin, climate, and harvesting methods.

4. Use in Flavors
In flavor applications, citronella oil Java is used to impart a citrusy, fresh note to a variety of products, including beverages, candies, and baked goods. It serves as a functional flavoring agent, often used in conjunction with other citrus flavors to enhance brightness and complexity. Typical use levels in finished food products range from 5 to 50 ppm, with higher concentrations potentially leading to overpowering flavors. The oil is relatively stable under acidic conditions but may degrade under prolonged heat exposure, necessitating careful formulation considerations.

5. Use in Fragrances
Citronella oil Java is a staple in the fragrance industry, particularly in the formulation of fresh, citrusy perfumes and personal care products. It is commonly used in fragrance families such as citrus, fougère, and chypre. The oil acts as a top note, providing an initial burst of freshness that is both invigorating and uplifting. Typical concentration ranges in fragrance formulations vary from 0.1% to 5%, depending on the desired intensity and product type. Its volatility ensures a prominent top note contribution, while its moderate tenacity allows it to blend well with other fragrance components.

5a. Key Constituents (Typical)
Citronella oil Java is composed of several key constituents, including citronellal, geraniol, citronellol, and limonene. These compounds are responsible for the oil's characteristic lemony aroma. The composition of these constituents can vary based on factors such as plant variety, cultivation conditions, and extraction methods. Citronellal typically constitutes the largest portion, followed by geraniol and citronellol, which contribute to the oil's floral and citrus notes.

6. Regulatory Status (Regional Overview)
In the United States, citronella oil Java is recognized as GRAS (Generally Recognized As Safe) for flavor use by FEMA. In the European Union, it is regulated under Regulation (EC) No 1334/2008 and is assigned the FL number 2260. The United Kingdom follows similar regulations post-Brexit. In Asia, countries like Japan and China have specific guidelines for its use in flavors and fragrances, while ASEAN countries generally align with international standards. In Latin America, regulatory frameworks such as those in Brazil and MERCOSUR recognize its use with certain restrictions on concentration levels.

7. Toxicology, Safety & Exposure Considerations
Citronella oil Java is generally considered safe for use in both flavor and fragrance applications when used within recommended concentration limits. For oral exposure, the oil's components have been evaluated for safety, with no significant adverse effects reported at typical use levels. Dermal exposure in fragrance applications may pose a risk of irritation or sensitization, particularly in sensitive individuals, necessitating adherence to IFRA guidelines. Inhalation exposure is generally low risk, but occupational exposure should be managed to prevent respiratory irritation.

8. Practical Insights for Formulators
Citronella oil Java is valued for its bright, citrusy aroma, which can enhance both flavor and fragrance formulations. It synergizes well with other citrus and floral notes, providing a fresh, uplifting character. Formulators should be cautious of its strong aroma, which can easily dominate a blend if used excessively. It is often under-utilized in complex fragrance compositions where its potential to add freshness is overlooked.

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.
