What is Phenethyl Cinnamate?
Phenethyl cinnamate is an ester compound composed of phenethyl alcohol and cinnamic acid. It occurs naturally in small quantities in various plants and fruits, contributing to their characteristic aromatic profiles. The compound is a clear to pale yellow liquid with a pleasant fruity and floral odor reminiscent of cinnamon, strawberry, and honey. In food manufacturing, it is synthesized chemically to ensure purity and consistency for use as a flavoring agent.
Common Uses
Phenethyl cinnamate is used primarily in the flavor and fragrance industry. In food applications, it functions as a flavoring agent in products such as beverages, confectionery, baked goods, dairy products, and desserts. The compound is typically used in very small concentrations—often measured in parts per million—to provide or enhance fruity, floral, and spice-like flavor notes. It is also utilized in the fragrance industry for cosmetics and personal care products due to its pleasant aromatic characteristics.
Safety Assessment
The FDA has not evaluated phenethyl cinnamate for GRAS (Generally Recognized as Safe) status. However, the absence of a formal GRAS determination does not indicate that the substance is unsafe; rather, it means that manufacturers using this ingredient may do so under the FDA's food additive regulations without a specific GRAS affirmation.
According to available FDA records, there have been zero reported adverse events associated with phenethyl cinnamate and zero product recalls linked to this ingredient. This lack of adverse event reports, combined with its structural similarity to naturally occurring compounds and its limited use at low concentrations, suggests a favorable safety profile.
As an ester of cinnamic acid and phenethyl alcohol—both compounds with established histories of use in foods and fragrances—phenethyl cinnamate presents a low inherent toxicity risk. The compound is metabolized through standard hepatic and renal pathways when ingested in food quantities. Acute toxicity studies on structurally similar compounds indicate low oral toxicity, and there is no evidence of genotoxic or carcinogenic potential at food-use levels.
Regulatory Status
In the United States, phenethyl cinnamate may be used as a flavoring agent in food products under 21 CFR 182.60 (flavoring agents generally recognized as safe) or under the food additive petition process. The ingredient is not banned by the FDA and does not appear on any prohibited substance lists.
In Europe, phenethyl cinnamate is listed in the EFSA's flavor database and has been evaluated as acceptable for use in food flavorings. It complies with EU Regulation (EC) No 1334/2008 on flavorings.
The compound is also permitted in food applications in several other jurisdictions, including Canada, Australia, and Japan, where it has been assessed and determined to be acceptable for use at typical flavor concentrations.
Key Studies
Limited published safety data exists specifically for phenethyl cinnamate, which is typical for minor food ingredients used in trace amounts. However, relevant toxicological information comes from studies of structurally related compounds and from the Scientific Committee on Food (now EFSA) evaluations of flavoring substances. Cinnamic acid and phenethyl alcohol, the component parts of phenethyl cinnamate, have undergone safety assessments and are recognized as safe at food-use levels.
The low concentration at which phenethyl cinnamate is used in foods (typically 1-10 ppm) means that systemic exposure is minimal, further supporting its safety profile. The absence of adverse event reports across decades of use in the fragrance and flavor industry provides additional reassurance regarding safety in food applications.
