AInsights Entry for Violet Leaf Absolute (CAS: 8/6/24)
1. Identity & Chemical Information
Violet leaf absolute is a natural complex material derived from the leaves of the violet plant, typically Viola odorata. As an absolute, it is a concentrated, aromatic oil extracted using solvents. It does not have a single molecular structure but is a mixture of various compounds. The CAS number for violet leaf absolute is 8/6/24. It is important to note that the composition of violet leaf absolute can vary significantly depending on the geographical origin, harvest time, and extraction method used.

2. Sensory Profile
Violet leaf absolute is renowned for its distinctive green, leafy, and slightly floral aroma, often described as reminiscent of freshly cut grass with a hint of cucumber. It is a powerful and intense fragrance, typically used as a heart note in perfumery to impart a natural, green freshness. The odor threshold is not clearly reported, but it is known for its strong diffusion and lasting power, making it a valuable component in both fine fragrances and functional products.

3. Natural Occurrence & Formation
Violet leaf absolute is primarily sourced from the leaves of the Viola odorata plant. The formation of its characteristic aroma compounds involves enzymatic processes within the plant, which are further concentrated during the solvent extraction process. This material is often used in products labeled as "natural fragrance" due to its plant origin and minimal processing.

4. Use in Flavors
In flavor applications, violet leaf absolute is used sparingly due to its intense aroma. It is typically employed in luxury food products and beverages to impart a subtle green note. The typical use levels in finished products range from 0.1 to 5 ppm, depending on the desired intensity and the complexity of the flavor system. It is relatively stable under normal conditions but can degrade under high heat or acidic conditions.

5. Use in Fragrances
Violet leaf absolute is a staple in the fragrance industry, particularly in green and floral fragrance families. It serves as a modifier and impact note, providing a fresh, natural quality to perfumes. Typical concentration ranges in fragrance formulations are from 0.1% to 2%, depending on the desired effect. It is considered a middle note due to its moderate volatility and ability to blend well with both top and base notes.

6. Regulatory Status (Regional Overview)
In the United States, violet leaf absolute is generally recognized as safe (GRAS) for use in flavors by FEMA. In the European Union, it is regulated under Regulation (EC) No 1334/2008 and has an assigned FL number. The regulatory status in the United Kingdom remains aligned with the EU post-Brexit. In Asia, regulations vary, with Japan and China having specific guidelines for natural flavor materials. In Latin America, countries like Brazil follow MERCOSUR regulations, which are generally harmonized with international standards.

7. Toxicology, Safety & Exposure Considerations
For oral exposure, violet leaf absolute is considered safe at typical flavor use levels, with no specific ADI or MSDI established. Dermal exposure in fragrance applications is generally safe, but it may cause irritation or sensitization in sensitive individuals. IFRA provides guidelines for its use in fragrances to minimize these risks. Inhalation exposure is typically low risk, but occupational exposure should be managed with appropriate ventilation and protective equipment.

8. Practical Insights for Formulators
Violet leaf absolute is valued for its ability to impart a natural, green freshness to both flavors and fragrances. It synergizes well with floral and citrus notes but can be overpowering if used excessively. Formulators should be cautious of its intensity and potential for causing irritation in high concentrations. It is often underused in flavor applications due to its cost and potency.

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.
