What is Cinnamon Leaf Oil, Rectified?
Cinnamon Leaf Oil, Rectified (CAS Number 977184-45-4) is a processed essential oil obtained from the leaves of cinnamon plants, primarily Cinnamomum verum or related species. The term "rectified" indicates the oil has undergone additional purification or redistillation beyond standard essential oil extraction, a process designed to remove unwanted components, concentrate active constituents, or improve product consistency and stability.
Essential oils from cinnamon leaves differ chemically from cinnamon bark oil. While cinnamon bark oil is rich in cinnamaldehyde, cinnamon leaf oil typically contains higher concentrations of eugenol, linalool, and other volatile compounds. The rectification process may further alter the compositional profile.
Common Uses
The specific culinary or food manufacturing applications for Cinnamon Leaf Oil, Rectified are not well-documented in available regulatory databases. Essential oils derived from cinnamon are occasionally used in the food industry as flavoring agents, fragrance components, or natural preservative additives in very small concentrations. However, without established FDA guidance on this particular rectified form, its actual prevalence in food products remains unclear.
Essential oils in general require careful handling due to their concentrated nature and potential volatility during processing and storage.
Safety Assessment
According to FDA records, there are zero adverse event reports and zero recalls associated with Cinnamon Leaf Oil, Rectified. This absence of reported incidents suggests either minimal commercial use, strong safety margins in typical applications, or both.
Cinnamon essential oils have been used traditionally in culinary and medicinal contexts for centuries. However, undiluted essential oils can cause irritation at high concentrations. When used as food additives, essential oils are typically employed in minute quantities where safety concerns are substantially reduced.
The European Food Safety Authority (EFSA) maintains approval for certain cinnamon-derived substances as flavorings, though specific assessments for this particular rectified leaf oil product may not be individually documented.
Regulatory Status
Cinnamon Leaf Oil, Rectified has not received FDA GRAS (Generally Recognized as Safe) status. This does not necessarily indicate a safety concern but rather reflects that formal GRAS determination has not been pursued or established through the FDA's notification process.
Without GRAS status, manufacturers using this ingredient in food products would technically require FDA food additive approval, though the regulatory landscape for essential oils remains complex. Some essential oil components may qualify under flavor regulations or existing exemptions, depending on their specific application and concentration.
This additive falls outside primary regulatory categories in the FDA's database, classified simply as "other," indicating insufficient documentation of intended function or usage patterns.
Key Studies
Limited published research exists specifically on Cinnamon Leaf Oil, Rectified as a food additive. Most scientific literature on cinnamon essential oils focuses on cinnamon bark oil rather than leaf oil, and addresses antimicrobial or antioxidant properties in non-food research contexts.
The absence of established adverse events, combined with the long history of cinnamon use in food, suggests this rectified oil likely poses minimal risk at typical food additive concentrations. However, comprehensive safety studies specific to this purified form and its intended food applications would strengthen the evidence base.
Additional research documenting the exact chemical composition of different commercial rectified cinnamon leaf oil products, stability testing, and potential interactions with food matrices would help clarify appropriate usage levels and applications.
