What is 2,6,6-trimethyl-1 and 2-cyclohexen-1-carboxaldehyde?
2,6,6-trimethyl-1 and 2-cyclohexen-1-carboxaldehyde is a synthetic flavoring compound belonging to the aldehyde family of aromatic chemicals. Its CAS number is 977045-71-8. This compound is composed of a cyclohexene ring structure with a carboxaldehyde functional group and three methyl substituents. The compound exists in nature or is produced synthetically for use in food flavoring applications. It is typically a liquid or solid at room temperature with characteristic aromatic properties.
Common Uses
This flavoring agent is used primarily in the food and beverage industry as a flavor enhancer and flavoring adjuvant. It is commonly incorporated into:
- Confectionery and candy products
- Baked goods and pastries
- Dairy products and ice cream
- Beverages, including soft drinks and flavored waters
- Savory snacks and processed foods
- Condiments and sauces
The compound contributes specific aromatic notes that food manufacturers use to enhance or create desired flavor profiles. Like other synthetic flavoring agents, it is used in very small quantities—typically measured in parts per million (ppm)—to achieve the desired sensory effect.
Safety Assessment
As of the available data, there have been zero adverse events reported to the FDA associated with this additive, and no product recalls have been linked to its use. However, it is important to note that this compound has not been designated as Generally Recognized as Safe (GRAS) by the FDA.
The lack of GRAS status means the compound has not undergone the comprehensive safety review process required for GRAS designation, or such review has not been completed. This does not necessarily indicate a safety concern but rather indicates that formal FDA approval or recognition under the GRAS provision has not been established. Food manufacturers using this ingredient would typically do so under FDA Food Additive Petition procedures or may use it in flavoring compounds that have been previously approved.
Limited published scientific literature is available specifically evaluating the toxicology and safety profile of this particular compound in isolation. The structural similarity to other approved aromatic aldehydes used in flavoring may provide some reassurance regarding safety, but direct evidence is limited.
Regulatory Status
In the United States, the regulatory status of this compound remains unclear without GRAS designation. It may be used under approved food additive regulations or as part of a flavoring mixture that has been evaluated and approved by the FDA.
The European Food Safety Authority (EFSA) maintains a Flavouring Group Evaluation (FGE) system for assessing flavoring compounds. While specific EFSA approval status for this exact compound is not detailed in available summary data, structurally similar aromatic aldehydes have undergone EFSA evaluation.
Jurisdictions vary in their acceptance of synthetic flavoring compounds. Some regions maintain positive lists of approved flavorings, while others use different regulatory frameworks. Food manufacturers exporting products containing this ingredient would need to verify compliance with regulations in destination markets.
Key Studies
Specific peer-reviewed toxicology studies focused exclusively on 2,6,6-trimethyl-1 and 2-cyclohexen-1-carboxaldehyde are not prominently documented in widely accessible scientific literature. Safety assessments for flavoring compounds typically consider:
- Acute toxicity studies
- Subchronic and chronic toxicity data
- Mutagenicity and genotoxicity testing
- Reproductive and developmental toxicity evaluation
- Metabolism and kinetic studies
For compounds lacking published independent studies, safety may be inferred through structure-activity relationship (SAR) analysis and comparison to chemically similar, approved flavoring agents. The aldehyde functional group is present in many approved flavorings, suggesting potential safety precedent.
