Overview
Acetyl triethyl citrate (CAS 77-89-4 ), commonly abbreviated as ATEC, is a citrate ester plasticizer derived from citric acid used across food-contact, pharmaceutical, and polymer applications.
It functions as a non-phthalate plasticizer and solvent, offering formulators a compliant alternative for flexible film and coating systems. In pharmaceutical manufacturing, ATEC plasticizes enteric coatings.
It improves flexibility and adhesion for tablets and capsules without compromising release profiles. Flexible PVC and cellulose-based polymer compounds use ATEC to achieve target elongation and softness.
This material is ideal for food-contact packaging films and medical tubing. Personal care formulators incorporate it as a solvent and film-former carrier in nail lacquers and topical delivery systems.
In food-contact applications, it meets regulatory requirements for direct and indirect contact materials. This makes it a preferred choice where phthalate-free compliance is mandatory for safety.
Acetyl triethyl citrate is supplied as a clear, low-viscosity liquid in drum and IBC quantities. It is available in food-grade and pharmaceutical-grade specifications for industrial-scale procurement.
The material conforms to USP and BP monographs where required for regulated industries. Technical-grade material is also offered for polymer and industrial coating applications.
