Tributyl citrate

Tributyl citrate (CAS 77-94-1), also called TBC or butyl citrate, is a citrate ester plasticizer.

Where is Tributyl citrate used?

• Polymer processing: plasticizer and stabilizer imparting flexibility and processing performance while meeting low-toxicity requirements
• PVC and cellulose-based formulations: improves film flexibility and elongation for food-contact packaging and medical tubing
• Children's products: used where regulatory compliance limits phthalate use
• Personal care: nail lacquers and film-forming cosmetic products
• Adhesion and wear performance as a plasticizing agent
• Food-grade contexts: humectant and stabilizer in flavor encapsulation and coating systems
• It also acts as an antioxidant synergist in fat-containing formulations to extend shelf life.

Good to know: Food-grade material is produced to FCC standards; buyers sourcing for EU food-contact or cosmetic end uses should confirm compliance documentation against relevant regional regulations.
