What is Methyl 1-acetoxycyclohexyl Ketone?
Methyl 1-acetoxycyclohexyl ketone (CAS Number: 52789-73-8) is a synthetic organic compound belonging to the class of ketone-based flavor compounds. It is characterized by a cyclohexyl ring with an acetoxy group and a methyl ketone functionality. This compound is manufactured through chemical synthesis for use exclusively as a flavoring agent in food applications.
Common Uses
Methyl 1-acetoxycyclohexyl ketone is employed in the food industry as a flavoring agent or flavor adjuvant. Its specific applications include use in beverage flavorings, confectionery products, and other processed foods where synthetic flavor profiles are desired. The compound contributes to the overall sensory characteristics of food products by providing specific taste and aromatic notes. Like many synthetic flavoring compounds, it is used in very small quantities to achieve the desired flavor effect.
Safety Assessment
The safety profile of methyl 1-acetoxycyclohexyl ketone is characterized by limited adverse event data. According to FDA records, there have been zero reported adverse events associated with this additive, and zero food recalls linked to its use. This absence of documented safety incidents suggests that when used as intended in food products, the compound has not raised significant safety concerns in the United States food supply.
However, it is important to note that this additive has not received Generally Recognized as Safe (GRAS) status from the FDA. This classification does not necessarily indicate the compound is unsafe; rather, it indicates that sufficient evidence of safety through expert consensus has not been formally established through the GRAS notification process. The compound may still be used in foods under FDA regulations for food additives, which include safety requirements for all permitted uses.
Regulatory Status
Methyl 1-acetoxycyclohexyl ketone is not GRAS-listed by the FDA. It functions as an approved food additive under FDA regulations when used in accordance with established safety guidelines. The lack of GRAS status means the compound was not affirmed through the streamlined GRAS notification process but may still be used under the general food additive regulatory framework, which requires adequate safety data to support its use.
In the European Union and other international markets, synthetic flavoring compounds are subject to evaluation by the European Food Safety Authority (EFSA) and other regulatory bodies. Specific approval status in these jurisdictions may vary.
Key Studies
Scientific literature on methyl 1-acetoxycyclohexyl ketone is limited in the public domain. The compound's safety assessment is based primarily on its chemical structure, analogous compounds' safety data, and its history of use in food applications at very low concentrations. Toxicological assessments for synthetic flavoring compounds typically evaluate acute toxicity, genotoxicity, and chronic exposure effects.
As with most minor flavor compounds used at trace levels in food, comprehensive published toxicological studies specific to this compound may be proprietary or limited. The absence of adverse event reports over the period of its use in food products provides practical evidence of safe use under normal conditions and intended application rates.
Consumers should note that synthetic flavoring agents are used in extremely small quantities—typically measured in parts per million in finished food products—which significantly reduces potential exposure and associated risk.
