What is Cinnamyl Benzoate?
Cinnamyl benzoate (CAS Number 5320-75-2) is a synthetic ester compound created through the chemical combination of benzoic acid and cinnamyl alcohol. It belongs to the benzoate family of flavor compounds and is classified as a flavoring agent or flavoring adjuvant. The compound is colorless to pale yellow and is used primarily in the fragrance and food flavoring industries to deliver cinnamon, spice, and warm aromatic notes to products.
Common Uses
Cinnamyl benzoate is utilized as a flavoring ingredient in various food and beverage applications where cinnamon or spice-like flavors are desired. These may include baked goods, confectionery products, beverages, dairy products, and other processed foods. The compound allows manufacturers to achieve consistent, stable cinnamon flavoring without relying solely on natural cinnamon extracts. As a synthetic flavoring, it offers advantages in terms of standardization, cost-effectiveness, and shelf stability compared to some natural alternatives.
Safety Assessment
Cinnamyl benzoate has not been formally approved by the FDA as a Generally Recognized As Safe (GRAS) substance, meaning it does not have this specific regulatory designation in the United States. However, the available safety data is notable: there are zero reported adverse events linked to cinnamyl benzoate in FDA records and zero recalls associated with the compound. This absence of documented safety incidents suggests a favorable safety profile in actual use.
The parent compounds—benzoic acid and cinnamyl alcohol—have extensive safety data. Benzoic acid and its salts are widely used as preservatives and have been extensively studied. Cinnamyl alcohol is recognized as a flavoring substance in various regulatory frameworks. The ester derivative, cinnamyl benzoate, would be expected to have similar safety characteristics, though specific toxicological studies on this particular compound may be limited in public literature.
Regulatory Status
In the United States, cinnamyl benzoate does not have FDA GRAS approval. This means it cannot be used in food without appropriate regulatory authorization through other pathways, such as food additive petition or as part of a flavoring complex approved by the FDA. The FDA maintains a list of approved flavoring substances, and cinnamyl benzoate's status should be verified before commercial use in food products intended for the U.S. market.
In the European Union, cinnamyl benzoate may be evaluated under different regulatory frameworks for flavoring substances. Manufacturers considering use of this compound should verify compliance with applicable regulations in their target markets, as flavoring regulations vary significantly between jurisdictions.
Key Studies
Published literature specifically examining cinnamyl benzoate is limited in public databases. The compound's safety profile is largely informed by knowledge of its parent compounds and established principles of ester chemistry. Benzoic acid and benzoate compounds have been extensively studied for safety, with regulatory agencies generally considering them safe at approved use levels. Cinnamyl alcohol has also undergone toxicological evaluation.
The absence of reported adverse events and recalls despite potential industrial use suggests that any safety concerns, if they exist, have not manifested in documented consumer incidents. However, the lack of GRAS status indicates that comprehensive safety documentation or petition submissions may not have been submitted to or approved by regulatory authorities.
Manufacturers and researchers interested in this compound should consult the FDA's Color Additives Status List and Flavoring Substances and Related Substances database, as well as comparable European resources, for current regulatory status and any submitted safety data.
