General description

Triethyl citrate is a safe direct food additive.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product can replace highly toxic diluents in membrane preparation and thus aligns with "Less Hazardous Chemical Syntheses". Click here for more information.

Application

Triethyl citrate was used as a plasticizer in the study of the feasibility of near-infrared (NIR) spectroscopy in determining the influence of plasticizer levels and sintering temperature on the breaking force of extended-release matrix tablets prepared by roller-compaction.
