Application

Tributyl citrate acetate is a versatile, colorless, and odorless liquid that serves primarily as a plasticizer for polymers in various pharmaceutical coatings. While it has limited water solubility, it is readily soluble in organic solvents and is compatible with alcohol and oils. This makes it particularly effective for use in the formulation of pharmaceutical products such as capsules, tablets, beads, and granules. It is instrumental in enhancing the properties of these coatings, whether for taste masking or for achieving desired release profiles like immediate release, sustained release, and enteric formulations.
