Triethyl citrate is an ester of citrate. It is a colorless, odorless liquid used as a food additive, emulsifier and solvent (E No. E1505) to stabilize foam, especially as a whipping aid for egg whites. It is also used in pharmaceutical coatings and plastics.

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

Triethyl citrate has been used as a pseudo-emulsifier in e-cigarette liquids. Its function is essentially similar to that of lecithin used in food products, but has the possibility of vaporization that lecithin does not have.

Triethyl citrate is often added for its oil-controlling properties, which help maintain healthy skin and hair.

  • Hair Care: It is a moisturizing ingredient that moisturizes hair and gives it shine and luster. It also enhances the spreadability of hair care products and ensures even product distribution

Triethyl citrate can be extracted naturally from plants or synthesized in the laboratory. It is generally produced by the esterification reaction of citric acid and ethanol. In this process, citric acid and ethanol are mixed together in the presence of a catalyst. This reaction results in the formation of triethyl citrate and water as by-products. The resulting triethyl citrate is then purified to remove impurities and obtain the desired quality.
