Triethyl citrate is an ester of citric acid. It is a colorless, odorless liquid used as a food additive (E number E1505) to stabilize foams, especially as whipping aid for egg white.[4] It is also used in pharmaceutical coatings and plastics.[5]

Triethyl citrate is also used as a plasticizer for polyvinyl chloride (PVC) and similar plastics.[6]

Triethyl citrate has been used as a pseudo-emulsifier in e-cigarette juices.[7] It functions essentially like lecithin used in food products, but with the possibility of vaporization which lecithin does not have.
