Where is Acetyl tributyl citrate used?
- Flexible polymer systems: primary plasticizer and softener, bio-based alternative to phthalates
- PVC and cellulose-based films: preferred plasticizer
- Flavor and fragrance formulations: fixative and solvent carrier
- Nail lacquers and film-forming cosmetics: softening agent
- Polymer compounding: lubricant component and processing aid
- It improves flexibility and adhesion in many formulations.
Good to know: Food-contact grades meet FDA 21 CFR and EU plasticizer regulations; buyers should confirm purity levels and compliance documentation for the intended end-use market.
