FlavScents AInsights Entry for Erythroxylon Coca Lam. Leaf Extract (CAS: 84775-48-4)

1. Identity & Chemical Information

Erythroxylon coca lam. leaf extract is a natural complex material derived from the leaves of the Erythroxylon coca plant. It is commonly referred to as coca leaf extract. The CAS number for this extract is 84775-48-4. As a natural complex material, it does not have a single molecular formula or molecular weight. Instead, it is composed of a variety of chemical constituents, which can vary based on the plant's origin, harvest time, and processing methods. This extract is not typically associated with a FEMA number or other specific identifiers like FL or CoE numbers.

2. Sensory Profile

Coca leaf extract is known for its unique sensory profile, which includes a mild, tea-like aroma with subtle earthy and herbal notes. The flavor is often described as slightly bitter with a hint of sweetness, reminiscent of green tea. The intensity of the aroma and flavor can vary depending on the concentration and specific batch of the extract. It is typically used as a background note in flavor formulations, providing a sense of authenticity and complexity.

3. Natural Occurrence & Formation

Coca leaf extract is naturally sourced from the leaves of the Erythroxylon coca plant, which is native to South America. The leaves are traditionally harvested and processed to extract the complex mixture of alkaloids and other compounds. The formation of the extract involves drying and macerating the leaves, followed by solvent extraction. This extract is often used in products labeled as "natural flavor" due to its plant-based origin.

4. Use in Flavors

In the flavor industry, coca leaf extract is used primarily in beverages and confectionery products. It serves as a flavor enhancer, adding depth and complexity to the overall flavor profile. Typical use levels in finished products range from 10 to 100 ppm, depending on the desired intensity and application. The extract is relatively stable under normal processing conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

Coca leaf extract is less commonly used in fragrances compared to flavors. When used, it is typically found in niche or artisanal fragrance products, contributing a subtle herbal and earthy note. It can function as a modifier or background note, enhancing the overall complexity of the fragrance. The extract is generally used at low concentrations due to its distinctive aroma profile.

5a. Key Constituents (Typical)

The key constituents of coca leaf extract include a variety of alkaloids, with cocaine being the most well-known, although it is typically present in very low concentrations in commercial extracts. Other constituents include cinnamoylcocaine, truxillines, and various terpenes. The composition can vary significantly based on the geographic origin and processing methods.

6. Regulatory Status (Regional Overview)

In the United States, coca leaf extract is subject to strict regulation due to the presence of cocaine. It is not generally recognized as safe (GRAS) for use in foods or beverages. In the European Union, the extract is similarly restricted under Regulation (EC) No 1334/2008. The United Kingdom follows EU regulations post-Brexit. In Asia and Latin America, regulatory status varies, with some countries allowing limited use under specific conditions. Explicit approvals are rare, and harmonized assumptions are not common due to the extract's controversial nature.

7. Toxicology, Safety & Exposure Considerations

The primary safety concern with coca leaf extract is its potential cocaine content, which poses risks of addiction and toxicity. Oral exposure through flavor use is highly regulated, and any use must ensure negligible cocaine content. Dermal exposure in fragrance use is less common but should be approached with caution due to potential sensitization. Inhalation exposure is not typically a concern due to low volatility. The risk profiles differ significantly between food and fragrance applications, with stricter controls in place for food use.

8. Practical Insights for Formulators

Coca leaf extract is valued for its unique sensory attributes, which can enhance the authenticity of certain flavor profiles. It pairs well with other herbal and earthy notes, creating a balanced and complex flavor. Formulators should be cautious of regulatory restrictions and ensure compliance with local laws. Overuse can lead to undesirable bitterness, while underuse may result in a lack of depth.

9. Confidence & Data Quality Notes

Data on coca leaf extract is well-established in terms of its sensory profile and key constituents. However, regulatory and safety data are complex due to the presence of cocaine. Industry practices often rely on careful sourcing and processing to minimize risks. Known data gaps include comprehensive safety assessments for non-food applications.

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.
