What is 4-(2,6,6-trimethylcyclohexa-1,3-dienyl)but-2-en-4-one?
4-(2,6,6-trimethylcyclohexa-1,3-dienyl)but-2-en-4-one, identified by CAS number 23696-85-7, is a synthetic flavoring compound belonging to the ionone family of aromatic chemicals. Ionones are a group of organic compounds characterized by a cyclohexene ring with specific substituents that create distinctive fruity and floral aromatic profiles. This particular compound is valued in the fragrance and flavoring industries for its ability to contribute complex sensory characteristics to food and beverage formulations.
Common Uses
This flavoring agent is primarily used in the food and beverage industry to enhance taste profiles and add aromatic complexity to products. Common applications include:
- Fruit-flavored beverages (juices, soft drinks, flavored waters)
- Confectionery products (candies, chewing gums, hard candies)
- Baked goods and desserts
- Dairy products (yogurts, flavored milks)
- Ice cream and frozen desserts
- Savory snack seasonings
The compound typically appears in formulations at very low concentrations, as flavoring agents are generally used at levels ranging from parts per million (ppm) to a few hundred ppm depending on the food category and desired intensity.
Safety Assessment
This additive currently has no reported adverse events recorded with the FDA and zero associated recalls in the FDA database. The absence of adverse event reports suggests that any safety concerns, if present, have not manifested in documented consumer complaints or health incidents in the United States market.
However, it is important to note that this compound is not on the FDA's Generally Recognized as Safe (GRAS) list. This designation does not necessarily indicate a safety problem; rather, it reflects that the additive has not undergone the formal GRAS affirmation process or does not meet the specific criteria for GRAS status under FDA regulations. Some flavoring ingredients function safely in food through the Food Additives Amendment approval process or through the Flavor and Extract Manufacturers Association (FEMA) GRAS program, which operates in coordination with FDA oversight.
The ionone class of compounds has a long history of use in flavoring applications, and many structurally similar compounds have been evaluated for safety. The lack of reported adverse events and recalls suggests the compound has not presented obvious safety red flags in the marketplace.
Regulatory Status
The regulatory status of this compound varies by jurisdiction. In the United States, while not listed as GRAS, its presence in food products indicates it exists within the regulatory framework. Some flavoring agents operate under FDA food additive petitions or through industry self-affirmed GRAS determinations that have been notified to FDA through the GRAS Notification Program.
International regulatory bodies may have different classifications. The European Union's food additive regulations maintain separate approval lists, and this compound may or may not appear on EU approved flavoring lists depending on safety dossier submissions and regulatory determinations made by European authorities.
Any use of this additive in food products should comply with applicable regulations in the relevant jurisdiction and adhere to concentration limits established through regulatory approval.
Key Studies
Specific published safety studies on this particular ionone derivative appear limited in publicly available scientific literature. Safety evaluation of flavoring compounds typically occurs through:
- FEMA Expert Panel assessments, which evaluate structural categories of flavoring compounds
- Proprietary safety data submitted to regulatory agencies
- Toxicological studies conducted as part of food additive petitions
For compounds within the ionone structural category, broader safety assessments have generally supported their use in flavoring applications at typical use levels. Researchers evaluating ionone compounds have examined acute toxicity, genetic toxicity, and metabolic fate to inform safety conclusions.
