Acetyl tributyl citrate

Acetyl tributyl citrate (CAS 77-90-7), commonly abbreviated as ATBC, is a citrate ester plasticizer derived from citric acid used across food-contact, personal care, and industrial applications. It functions as a primary plasticizer and softener, offering a bio-based alternative to phthalate plasticizers in flexible polymer systems. This material is a preferred plasticizer for PVC and cellulose-based films.

In food packaging, regulatory compliance with food-contact standards is a procurement priority. In flavor and fragrance formulations, it acts as a fixative and solvent carrier for various industrial systems. The product carries FEMA 3080 status supporting its use in food-grade flavor systems. Personal care manufacturers incorporate it into nail lacquers and film-forming cosmetic products as a softening agent.

It improves flexibility and adhesion in many formulations. Industrial formulators also use it as a lubricant component and processing aid in polymer compounding operations to ensure high performance. The chemical is supplied as a clear, low-viscosity liquid in drum and IBC quantities suited to bulk industrial procurement. It is available in food-grade and technical-grade specifications for buyers.

Food-contact grades meet standards such as FDA 21 CFR and EU plasticizer regulations. Buyers should confirm purity levels and specific compliance documentation based on the intended end-use market requirements.
