What is 1-amino-2-propanol?
1-amino-2-propanol (also known as 1-amino-2-propyl alcohol or isopropanolamine) is an organic chemical compound with the CAS number 78-96-6. Structurally, it is a three-carbon chain with an amino group (-NH2) and a hydroxyl group (-OH), making it both an amine and an alcohol. The compound exists as a colorless to pale yellow liquid with a slight odor.
Common Uses
In the food industry, 1-amino-2-propanol functions as a flavoring agent and flavoring adjuvant. Flavoring adjuvants are substances that support or enhance the performance of primary flavor compounds without necessarily providing flavor themselves. This additive may be used in various processed foods, beverages, and flavoring formulations where it contributes to desired sensory characteristics.
Beyond food applications, 1-amino-2-propanol has industrial uses in manufacturing processes, cosmetics, and pharmaceutical formulations, though this content focuses specifically on its food-related applications.
Safety Assessment
According to FDA records, there have been zero adverse events reported in connection with 1-amino-2-propanol as a food additive, and no food recalls have been linked to this substance. These data points indicate that reported safety incidents are absent from the FDA's surveillance systems.
Toxicological information on 1-amino-2-propanol from non-food sources indicates the compound has low acute toxicity. However, the lack of formal GRAS (Generally Recognized as Safe) status from the FDA indicates that comprehensive safety documentation meeting FDA's specific standards for food use has not been submitted or approved.
The distinction between "no reported adverse events" and "formally approved as safe" is important: absence of reported incidents does not automatically confer regulatory approval status. GRAS approval requires either a history of common use in food prior to 1958 or submission of a complete safety dossier to the FDA for evaluation.
Regulatory Status
1-amino-2-propanol is not listed as GRAS for food use by the FDA. This means it cannot be used in food under the GRAS exemption to food additive regulations. Any food manufacturer wishing to use this substance would need to either:
1. Petition the FDA for food additive approval with supporting safety data, or
2. Demonstrate a valid pre-1958 history of common use in food
The regulatory status varies by jurisdiction. While specific approvals in the European Union or other regulatory bodies would require consultation with those agencies' databases (such as the EFSA), the information provided here reflects FDA's current position.
Key Studies
Scientific literature on 1-amino-2-propanol is limited, particularly regarding its specific use as a food flavoring agent. Most available toxicological data derives from occupational health and industrial safety contexts rather than food safety research.
The absence of a substantial published research record specific to food use, combined with lack of GRAS approval, suggests that formal safety studies specifically designed for food additive purposes have not been completed or submitted to regulatory authorities.
Manufacturers considering use of this substance in food products should conduct appropriate safety testing and submit comprehensive documentation to the FDA for evaluation before marketing any products containing this ingredient.
