What is Nerolidol Oxide?
Nerolidol Oxide (CAS Number: 1424-83-5) is a synthetic organic compound classified as a flavoring agent and flavoring adjuvant. It is chemically derived from nerolidol, a naturally occurring sesquiterpene alcohol found in essential oils of plants such as jasmine, rose, and tea tree. The oxide form represents a modified version of the parent compound, created through oxidation processes to enhance specific aromatic properties desired in food applications.
Common Uses
Nerolidol Oxide is primarily employed in the food and beverage industry as a flavoring component. It is used in trace amounts to contribute woody, floral, and slightly sweet aromatic notes to products including baked goods, beverages, confectionery, and dairy products. As a flavoring agent, it functions to enhance or modify the sensory profile of foods rather than serve a preservative, coloring, or nutritional function. Like many synthetic flavoring compounds, it is used at very low concentrations—typically measured in parts per million (ppm)—to achieve the desired flavor impact.
Safety Assessment
Nerolidol Oxide has not been formally evaluated by the FDA under the GRAS (Generally Recognized as Safe) designation, meaning it does not have explicit FDA approval for safety at intended levels of use. However, this status does not indicate safety concerns; rather, it reflects that a formal GRAS petition or safety review has not been completed or submitted to the agency.
The compound's safety profile is supported by its structural relationship to nerolidol, which appears in natural sources, and the minimal quantities used in food applications. The very low exposure levels typical of flavoring agents—often measured in micrograms to milligrams per serving—contribute to favorable safety margins. As of the available FDA records, there are no reported adverse events or product recalls associated with Nerolidol Oxide, indicating no documented safety incidents in consumer use.
Similar synthetic flavor compounds undergo evaluation through the Flavor and Extract Manufacturers' Association (FEMA) Expert Panel, which assesses flavor safety using established protocols. The absence of adverse events in FDA surveillance systems suggests the compound has not raised safety concerns in the marketplace.
Regulatory Status
In the United States, Nerolidol Oxide operates in a regulatory gray area. Without GRAS status, it technically requires FDA approval for use as a food additive, which may be obtained through the food additive petition process. However, many flavor manufacturers operate under the assumption that such compounds are permitted under existing regulatory frameworks or through industry self-governance via FEMA GRAS assessments, which do not require FDA pre-approval.
International regulatory approaches vary. The European Union's flavoring regulations and databases may include this compound under different classification systems. Manufacturers intending to use or import products containing Nerolidol Oxide should verify compliance with applicable regulations in their target markets.
Key Studies
Limited published scientific literature specifically addresses Nerolidol Oxide as a discrete compound. Most safety information derives from its chemical relationship to parent compounds (nerolidol) and general principles of synthetic flavoring safety established through decades of regulatory practice.
Research on nerolidol itself indicates low toxicity and minimal bioaccumulation potential, supporting the safety profile of related compounds. Toxicological data typically relevant to flavor compound evaluation includes acute oral toxicity, mutagenicity, and subchronic exposure studies—standards applied across the flavoring industry.
The consistent absence of adverse event reports or recalls in FDA monitoring systems provides real-world evidence of safe use at marketed concentrations. This observational evidence, combined with the low exposure doses inherent to flavoring applications, supports the empirical safety record of this compound.
