What is Cinnamyl Alcohol?
Cinnamyl alcohol (CAS Number 104-54-1) is an unsaturated primary alcohol with the chemical formula C9H10O. It occurs naturally in cinnamon bark and other plant sources, though it is also produced synthetically for food applications. The compound features a phenyl ring attached to a propenyl side chain terminating in a hydroxyl group, giving it its characteristic aromatic properties.
Common Uses
Cinnamyl alcohol is primarily employed as a flavoring agent and flavor adjuvant in the food industry. Its applications include:
- Beverage flavoring, particularly in cinnamon-flavored drinks and spirits
- Baked goods and pastries requiring cinnamon notes
- Confectionery and candy formulations
- Savory seasonings and spice blends
- Processed foods where cinnamon flavor enhancement is desired
The compound is valued for its ability to provide authentic cinnamon flavor at lower concentrations than whole spice, allowing manufacturers to achieve consistent taste profiles while reducing material costs.
Safety Assessment
Cinnamyl alcohol has been the subject of limited safety evaluations compared to more widely used food additives. The compound shows no reported adverse events in FDA databases and has been associated with zero FDA recalls. This absence of documented safety incidents suggests that current usage levels in food products have not raised acute safety concerns.
Toxicological studies on cinnamyl alcohol are relatively sparse in the published literature. Available data from animal studies do not indicate significant acute toxicity at typical exposure levels. The compound's status as a naturally occurring substance in cinnamon provides some reassurance regarding its safety profile, though naturally occurring does not automatically equate to unrestricted safety at all concentrations.
Some individuals may experience contact sensitivity or allergic reactions to cinnamyl alcohol in cosmetic or personal care products; however, food applications typically involve much lower exposure levels. Individuals with cinnamon allergies should exercise caution with products containing this flavoring agent.
Regulatory Status
Cinnamyl alcohol is notably not on the FDA's GRAS (Generally Recognized as Safe) list. This classification does not necessarily indicate safety concerns; rather, it reflects that the compound has not undergone the formal GRAS petition process or lacks sufficient consensus among qualified experts regarding its safety for use in food.
The substance may be used in food products under FDA regulations as a flavor ingredient if it complies with food additive regulations and usage levels remain within established safety margins. The European Food Safety Authority (EFSA) has not formally assessed cinnamyl alcohol as a food additive, indicating it falls outside the scope of EU food additive approval processes.
Usage of cinnamyl alcohol in food products is permitted in various jurisdictions, though regulatory oversight varies by country and specific application.
Key Studies
Scientific literature on cinnamyl alcohol's safety in food applications is limited. Most available data comes from:
- Natural product chemistry research identifying cinnamyl alcohol in cinnamon and related botanicals
- Toxicology studies from cosmetic industry research, where higher dermal exposures are possible
- Flavor chemistry studies examining its contribution to cinnamon aroma profiles
The lack of reported adverse events in regulatory databases over decades of use suggests acceptable safety at current food application levels, though comprehensive risk assessment studies specific to food use would strengthen the evidence base. Additional research on long-term exposure effects would provide further certainty regarding safety margins.
