Regulatory evidence by market
No rule for this ingredient has been imported for any of the 13 markets tracked here.
That describes this inventory, not the law. No imported rule is not evidence that an ingredient is permitted: a rule may exist under another name or identifier, or in a dataset not yet imported here.
Chemical identity and properties
Propyl butyrate
Propyl butyrate is a butyrate ester resulting from the formal condensation of the hydroxy group of propanol with the carboxy group of butyric acid. It has a role as an insect attractant, a plant metabolite and a human metabolite. It is functionally related to a propan-1-ol. — ChEBI
