What is 4-Decenyl Acetate, Cis-?
4-Decenyl acetate, cis- (CAS Number 67452-27-1) is a synthetic organic compound belonging to the class of acetate esters. This flavoring agent is characterized by a cis configuration of its carbon double bond at the fourth position of its decenyl (ten-carbon) chain. The compound exists as a colorless to pale yellow liquid with fruity and floral aromatic characteristics. Like other esters, it is produced through chemical synthesis rather than extracted from natural sources.
Common Uses
4-Decenyl acetate, cis- is utilized as a flavoring agent and flavoring adjuvant in various food and beverage applications. Its primary function is to provide fruity, apple-like, and floral notes to finished products. The compound may be used in:
- Confectionery and candy products
- Baked goods and bakery items
- Beverages and soft drinks
- Dairy products
- Flavor formulations and compounds
As with all synthetic flavor compounds, it is typically used in very small quantities—often measured in parts per million (ppm)—to achieve the desired sensory profile without contributing significantly to the overall composition of the final product.
Safety Assessment
According to available FDA records, 4-decenyl acetate, cis- has generated zero reported adverse events and zero product recalls. This lack of negative safety data suggests the compound has not been associated with consumer health complaints or safety issues when used in food applications.
The compound is not included on the FDA's GRAS (Generally Recognized as Safe) list, which means it has not undergone the formal GRAS notification process or has not been determined to meet GRAS criteria through the agency's evaluation. However, the absence of GRAS status does not necessarily indicate a safety concern; rather, it reflects the regulatory pathway and historical approval status of the substance.
The European Food Safety Authority (EFSA) maintains separate assessments for flavoring substances used in the European Union. Manufacturers using this ingredient in food products must comply with applicable regulations in their respective jurisdictions.
Regulatory Status
4-Decenyl acetate, cis- operates within a complex regulatory framework for flavor additives. In the United States, synthetic flavoring agents are regulated under 21 CFR Part 182 and related sections. While this compound is not on the GRAS list, it may be used under other regulatory provisions depending on the specific food application and intended use level.
The regulatory status of flavoring compounds can vary significantly between regions. The European Union, for example, maintains the Union List of Flavourings, which specifies which flavor substances are permitted and under what conditions. Manufacturers must verify compliance with local regulations before using this ingredient in food products intended for specific markets.
Food manufacturers considering the use of 4-decenyl acetate, cis- should consult current regulatory guidance and may need to work with regulatory experts to ensure compliant use in their target markets.
Key Studies
Published scientific literature specific to 4-decenyl acetate, cis- is limited in the public domain. Most information regarding this compound's safety comes from:
- Chemical and structural analysis related to similar acetate ester flavoring compounds
- General toxicology data on comparable C10 esters
- Industry safety assessments submitted to regulatory agencies
- Absence of reported adverse events in regulatory databases
The lack of reported safety incidents and zero FDA recalls provide practical safety data, though comprehensive toxicological studies specific to this compound may not be publicly available. This is not uncommon for niche flavoring compounds with limited market penetration.
