Application

Tributyl citrate serves as a versatile plasticizer, primarily employed to enhance the mechanical properties and flexibility of various materials. It is an oily, clear, and odorless liquid that improves the ductility of poly(lactide) polymers and is incorporated into zein films for industrial processing. Additionally, tributyl citrate finds significant application in the pharmaceutical industry, where it is used to plasticize polymers in coatings for capsules, tablets, beads, and granules. These coatings serve diverse purposes, including taste masking and modifying drug release profiles, whether for immediate, sustained, or enteric release formulations.
