FlavScents AInsights Entry: Cabreuva Wood Oil (CAS: 68188-03-4)
1. Identity & Chemical Information
Cabreuva wood oil, also known as cabreuva essential oil, is a natural complex material derived from the wood of the Myrocarpus fastigiatus tree. This essential oil is characterized by its complex mixture of constituents rather than a single molecular structure. The CAS number for cabreuva wood oil is 68188-03-4. It does not have a specific FEMA number, as it is typically used more in fragrance applications than in flavors. Other identifiers such as FL number or CoE number are not commonly associated with this oil. The composition of cabreuva wood oil can vary significantly depending on the geographical origin, harvest time, and processing methods.

2. Sensory Profile
Cabreuva wood oil is renowned for its rich, woody, and slightly sweet aroma with balsamic undertones. It is often described as having a warm, comforting scent that can add depth and complexity to fragrance compositions. The intensity of the odor is moderate, making it suitable for use as a background note or a modifier in both perfumes and aromatherapy products. The oil's diffusion is relatively good, allowing it to blend well with other essential oils and fragrance materials. Specific odor thresholds are not well-documented, but its sensory role is primarily as a background realism enhancer or a subtle impact note.

3. Natural Occurrence & Formation
Cabreuva wood oil is naturally sourced from the Myrocarpus fastigiatus tree, which is native to South America, particularly Brazil and Paraguay. The oil is obtained through steam distillation of the wood. As a natural product, it qualifies for "natural fragrance" designation under various regulatory frameworks. The formation of its characteristic aroma is due to the complex interplay of its constituents, which include sesquiterpenes and other aromatic compounds.

4. Use in Flavors
While cabreuva wood oil is primarily used in fragrances, it can also be found in certain flavor applications, particularly where a woody or balsamic note is desired. It may be used in flavor categories such as confectionery, beverages, and baked goods. The typical use levels in flavors are not well-documented, but industry estimates suggest low ppm levels due to its potent aroma. Stability considerations include moderate resistance to heat and oxidation, making it suitable for various food processing conditions.

5. Use in Fragrances
Cabreuva wood oil is widely used in the fragrance industry, particularly in woody, oriental, and chypre fragrance families. It serves as a modifier or impact note, providing warmth and depth to the fragrance composition. Typical concentration ranges in perfumes are from trace amounts up to 5%, depending on the desired intensity and character of the final product. The oil contributes primarily to the middle and base notes due to its moderate volatility.

5a. Key Constituents (Typical)
The key constituents of cabreuva wood oil include sesquiterpenes such as nerolidol, farnesol, and guaiol, which contribute to its characteristic woody and balsamic aroma. The composition can vary significantly based on factors such as geographic origin and processing methods. It is important for formulators to verify the specific profile of the oil they are using.

6. Regulatory Status (Regional Overview)
In the United States, cabreuva wood oil is not specifically listed under FEMA GRAS but is used in fragrances under general safety guidelines. In the European Union, it is subject to the regulations of Reg. (EC) No 1334/2008 for flavorings and cosmetic regulations for fragrances. The UK follows similar guidelines post-Brexit. In Asia, regulations vary, with Japan and China having specific guidelines for natural fragrances. In Latin America, countries like Brazil recognize it under their national fragrance regulations.

7. Toxicology, Safety & Exposure Considerations
For oral exposure, cabreuva wood oil is used at low levels in flavors, minimizing potential toxicity. Dermal exposure in fragrances is more common, with considerations for irritation and sensitization. IFRA provides guidelines for safe use in perfumes. Inhalation exposure is generally considered safe at typical usage levels, but occupational exposure should be monitored. The risk profiles differ slightly between food and fragrance applications, with fragrance use requiring more stringent dermal safety assessments.

8. Practical Insights for Formulators
Cabreuva wood oil is valued for its ability to impart a warm, woody character to both flavors and fragrances. It synergizes well with other woody and balsamic notes, enhancing the overall complexity of the formulation. Common pitfalls include overuse, which can overpower other notes, and underuse, which may result in a lack of depth. It is frequently under-utilized in flavor applications due to its primary association with fragrances.

9. Confidence & Data Quality Notes
The data on cabreuva wood oil is well-established in terms of its sensory profile and fragrance applications. However, there are gaps in documented flavor use levels and specific regulatory approvals. Industry practices often rely on historical usage and expert judgment in the absence of comprehensive data.

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.
