Tributyl citrate is widely used as a non-toxic plasticizer in food packaging and medical devices due to its biocompatibility and low volatility. It is especially favored in polyvinyl chloride (PVC) formulations where it improves flexibility and durability without leaching harmful substances. Because of its resistance to hydrolysis and good thermal stability, it is suitable for applications requiring sterilization or prolonged storage. It is also used in cosmetics and personal care products as a skin-conditioning agent and solvent. In addition, tributyl citrate serves as a plasticizer in biodegradable polymers, supporting the development of environmentally friendly materials. Its low migration rate makes it ideal for use in children's products and food-contact materials.
