Acetyl Tributyl Citrate (ATBC), is a colorless, odorless liquid plasticizer derived from citric acid. It serves as an eco-friendly and non-toxic alternative to traditional phthalate-based plasticizers like DEHP. ATBC is widely recognized for its biocompatibility, low volatility, and excellent performance in enhancing the flexibility and durability of polymers such as PVC.
With a molecular formula of C20H34O8 and CAS number 77-90-7, ATBC is approved for use in food-contact materials, medical devices, and children’s products under various global regulations, including flavoring and packaging applications.
