What is 2-(2-hydroxyphenyl) Cyclopropanecarboxylic Acid Delta Lactone?
2-(2-hydroxyphenyl) Cyclopropanecarboxylic Acid Delta Lactone, identified by CAS number 5617-64-1, is a synthetic organic compound belonging to the lactone family of flavor compounds. Its molecular structure consists of a cyclopropane ring attached to a hydroxyphenyl group, with a lactone functional group that contributes to its flavor properties. This compound exists as a white to off-white crystalline solid and is designed to provide subtle flavor notes in food formulations.
Lactones are naturally occurring and synthetic compounds known for their fruity, creamy, and buttery organoleptic properties. This particular lactone derivative is manufactured through chemical synthesis rather than extraction from natural sources, classifying it as a synthetic flavoring substance.
Common Uses
As a flavoring agent and adjuvant, 2-(2-hydroxyphenyl) Cyclopropanecarboxylic Acid Delta Lactone is used in food manufacturing to enhance or modify the sensory profile of food and beverage products. Typical applications include:
- Confectionery and candy products
- Baked goods and pastries
- Dairy products and flavored milk
- Beverages and soft drinks
- Savory snack foods
- Flavor modulation in complex food formulations
The compound is added in small quantities—typically measured in parts per million (ppm)—since flavoring agents are potent and require minimal amounts to achieve desired sensory effects.
Safety Assessment
The safety profile of 2-(2-hydroxyphenyl) Cyclopropanecarboxylic Acid Delta Lactone is characterized by the absence of reported adverse events in FDA databases. The FDA has received zero adverse event reports associated with this additive, indicating no documented consumer complaints or safety concerns linked to its consumption in the United States.
Additionally, there are no FDA recalls associated with products containing this compound, suggesting satisfactory safety performance in commercial food applications. The compound's use at flavoring levels—which are inherently low concentrations—contributes to its favorable safety profile.
As with all synthetic flavoring substances, safety assessment typically considers toxicological data, including acute toxicity, chronic toxicity, genotoxicity, and reproductive effects. The absence of adverse event reports and recalls suggests that any toxicological testing conducted on this substance did not reveal significant safety concerns at authorized use levels.
Regulatory Status
Importantly, 2-(2-hydroxyphenyl) Cyclopropanecarboxylic Acid Delta Lactone has not received FDA GRAS (Generally Recognized as Safe) status. This means the compound has not been formally affirmed or self-determined as GRAS for its flavoring function under current FDA regulations. GRAS status requires either prior sanction, FDA affirmation, or a completed Notified Basis GRAS determination.
However, the absence of GRAS status does not indicate unsafety. Rather, it indicates the regulatory pathway or determination status of the substance. Some flavoring compounds are approved for use under FDA regulations through alternative pathways, such as food additive petitions or FDA color additive regulations, depending on the specific compound and its intended use.
Different regulatory agencies globally have varying requirements and approval lists for flavoring substances. The European Food Safety Authority (EFSA) maintains its own list of approved flavoring substances for use in the EU, with different substances approved for different jurisdictions.
Key Studies
Limited publicly available literature exists specifically on 2-(2-hydroxyphenyl) Cyclopropanecarboxylic Acid Delta Lactone, likely reflecting its relatively specialized application in the flavor industry. Safety information is typically generated during the development phase and may not be widely published in peer-reviewed journals unless specific safety concerns arise.
General toxicological data on structurally similar lactone compounds indicates that these substances are generally low in acute toxicity when ingested at flavoring levels. The cyclopropane ring system and hydroxyphenyl moiety are well-characterized functional groups in pharmaceutical and food chemistry.
Further research or regulatory documentation from manufacturers may provide additional data on absorption, metabolism, and excretion profiles, which are standard safety assessment parameters for flavoring substances.
