What is Eugenyl Formate?
Eugenyl formate (CAS Number: 10031-96-6) is a synthetic organic compound created by the esterification of eugenol with formic acid. Eugenol is a naturally occurring phenolic compound abundant in clove oil, nutmeg, and cinnamon. The formate ester derivative is used primarily as a flavoring agent in the food industry, providing a characteristic spicy, clove-like flavor profile to various food and beverage products.
Common Uses
Eugenyl formate is employed as a flavoring agent in food manufacturing, typically in very small concentrations. Its primary applications include:
- Beverages (soft drinks, alcoholic drinks, flavored waters)
- Confectionery and candy products
- Baked goods and desserts
- Savory snacks and seasonings
- Pharmaceutical and nutraceutical formulations
The compound is valued for its ability to deliver intense clove-like and spicy notes, allowing manufacturers to achieve desired flavor profiles with minimal quantities. Its use is particularly common in products where traditional spice flavors are desired but whole spices may be impractical.
Safety Assessment
Eugenyl formate has not been formally approved by the FDA as a Generally Recognized As Safe (GRAS) substance, though it is used in food applications in various jurisdictions. The FDA's adverse event database contains no reported incidents linked to this additive, and no product recalls have been issued related to eugenyl formate consumption.
Safety data on eugenyl formate specifically remains limited compared to broader research on eugenol itself. Eugenol, the parent compound, has been extensively studied and is generally recognized as safe in food applications at typical use levels. However, the formate ester form may have different absorption, metabolism, and biological activity characteristics compared to eugenol alone.
The absence of adverse events in FDA databases suggests that eugenyl formate, when used at permitted levels, has not demonstrated acute toxicity concerns in the U.S. food supply. Typical flavoring use levels are substantially below those used in toxicological studies.
Regulatory Status
Eugenyl formate's regulatory status varies by jurisdiction. While not GRAS-listed in the United States, it may be used in food under FDA regulations for synthetic flavoring substances when compliant with 21 CFR 172.515 (synthetic flavoring agents and adjuvants). In the European Union, it may be regulated under Regulation (EC) No 1334/2008 concerning flavorings for use in foods.
The compound is approved for use as a flavoring agent in select countries and is included in various international flavor ingredient databases. Manufacturers using eugenyl formate must comply with specific jurisdictional regulations regarding maximum permitted levels and labeling requirements.
Key Studies
Direct toxicological studies specifically on eugenyl formate are limited in published literature. Available safety assessments rely partly on:
- Data on eugenol safety profiles, which demonstrate low acute toxicity
- General knowledge of formate ester metabolism and safety
- Absence of adverse event reports in regulatory databases
The chemical structure suggests eugenyl formate would be metabolized similarly to other formate esters, with hydrolysis occurring in the gastrointestinal tract. Further independent safety research on eugenyl formate specifically would strengthen the safety evidence base, though current data does not suggest significant concerns at typical food use levels.
