Application

Tributyl citrate can be used:
  • To incorporate in zein film to enhance its mechanical properties for industrial processing.
  • As a plasticizer to improve the ductile properties of poly(lactide) polymers.

General description

Tributyl citrate is a common solvent and plasticizer for polymers like PVC and its copolymers that are used in food wrapping films. Also, it is a common plasticizer employed in food contact materials, cosmetics, and food additives.
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.
