2. Sensory Profile

Nerol oxide is known for its floral, citrus-like aroma with a hint of green freshness. It is often described as having a moderate intensity and good diffusion, making it a versatile component in both flavors and fragrances. The odor threshold is not clearly reported, but it is typically used as an impact note in formulations to impart a fresh, floral character.

3. Natural Occurrence & Formation

Nerol oxide naturally occurs in several essential oils, including those of neroli and petitgrain. It is formed through the enzymatic degradation of geraniol and nerol, which are common in many plant species. Its presence in natural sources allows it to be designated as a "natural flavor" or "natural fragrance" component, depending on the context of its use.

4. Use in Flavors

Nerol oxide is utilized in a variety of flavor categories, including citrus, floral, and herbal profiles. It serves as a functional component to enhance the freshness and authenticity of flavor systems. Typical use levels in finished food or beverage products range from 0.1 to 5 ppm, with industry-typical values often guiding formulation practices. It is relatively stable under normal conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

In the fragrance industry, nerol oxide is incorporated into floral and citrus fragrance families. It acts as a modifier and impact note, contributing to the top and middle notes of a fragrance composition. Typical concentration ranges are qualitative, with usage often dictated by the desired intensity and diffusion. Its volatility makes it suitable for enhancing the freshness of a fragrance.

7. Toxicology, Safety & Exposure Considerations

• Oral Exposure: Data not found for specific ADI or MSDI; generally considered safe at typical flavor use levels.
• Dermal Exposure: No specific IFRA restrictions; low potential for irritation or sensitization reported.
• Inhalation Exposure: Volatility suggests minimal occupational risk under normal use conditions.

Overall, the risk profiles for nerol oxide do not significantly differ between food and fragrance applications, with safety generally supported by its natural occurrence and historical use.

8. Practical Insights for Formulators

Nerol oxide is valued for its ability to impart a fresh, floral character to both flavors and fragrances. It synergizes well with other citrus and floral components, enhancing overall complexity. Formulators should be cautious of its volatility and potential degradation under extreme conditions. It is often under-used in formulations seeking a natural, fresh profile.

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.
