What is Benzyl Cinnamate?
Benzyl cinnamate (CAS Number 103-41-3) is an ester compound formed from benzyl alcohol and cinnamic acid. It is a colorless to pale yellow liquid with a sweet, fruity aroma reminiscent of strawberry, honey, and cinnamon. The compound occurs naturally in trace amounts in various plants and fruits, but is primarily produced through chemical synthesis for commercial use in the flavor industry.
Common Uses
Benzyl cinnamate is utilized as a flavoring agent in a variety of food and beverage products. Its primary applications include:
- Alcoholic beverages, particularly liqueurs and cordials
- Confectionery and candy products
- Baked goods and desserts
- Non-alcoholic beverages and soft drinks
- Dairy products and ice cream
- Chewing gum and mints
The compound typically appears in formulations at very low concentrations, measured in parts per million (ppm), where its aromatic properties can enhance or modify the overall flavor profile of the finished product.
Safety Assessment
Benzyl cinnamate has not been evaluated by the FDA as a Generally Recognized as Safe (GRAS) substance through formal petition. However, the substance has an established history of safe use in food applications. According to FDA records, there have been zero adverse events reported and zero recalls associated with benzyl cinnamate, indicating no documented safety concerns from consumer exposure through food products.
The European Food Safety Authority (EFSA) has evaluated structurally related compounds in the ester class and generally recognizes similar compounds as safe at the levels used in flavoring applications. Benzyl cinnamate is classified as a "naturally occurring" flavor constituent in several regulatory jurisdictions due to its presence in nature, which supports its use in food manufacturing.
Toxicological studies on benzyl cinnamate have not identified significant hazards at dietary exposure levels. The compound does not appear on lists of restricted or banned food additives in major regulatory jurisdictions, including the FDA, EFSA, or other international food safety organizations.
Regulatory Status
Benzyl cinnamate is not currently authorized under FDA's GRAS regulations as a food additive but is permitted in food products in several jurisdictions based on its history of use and the flavor industry's self-assessment under the Flavor and Extract Manufacturers Association (FEMA) GRAS program.
In the European Union, benzyl cinnamate is listed in the flavor database and is used in compliance with regulation EC 1334/2008 on flavorings. It appears in the FEMA GRAS list (FEMA Number 2146), which provides an alternative regulatory pathway for flavor ingredients with an established safety record.
Regulatory approval and permitted use levels vary by country. Manufacturers using benzyl cinnamate must comply with local food additive regulations and labeling requirements in their respective markets.
Key Studies
Limited published toxicological data specifically addresses benzyl cinnamate in isolation. However, as a simple ester structure, its safety profile is supported by:
- General toxicology of cinnamate esters, which show low acute toxicity
- Historical use data demonstrating absence of reported adverse effects
- Structure-activity relationship assessments comparing it to related esters already approved for food use
- FEMA Expert Panel evaluations supporting its safe use at flavoring levels
The absence of adverse events and recalls in FDA databases over decades of use provides empirical evidence of safety at current exposure levels. Additional published research is limited, partly because regulatory acceptance has been established through industry self-assessment rather than formal FDA petition.
