Citroflex citric acid esters provide a wide range of benefits when used as plasticizers with aqueous- and solvent-based polymers, including acrylic, methacrylic, ethyl cellulose, hydroxypropyl methyl cellulose, nitrocellulose, vinyl acetate, vinyl chloride, vinyl pyrrolidone, vinylidene chloride, and urethane polymer systems. Vertellus Specialties Inc. offers both hydrophilic and lipophilic Citroflex esters, allowing the formulator to control the characteristics of polymer systems to suit the needs of the finished product.

The Citroflex esters offer the formulator a unique combination of environmentally friendly, desirable features. They are not volatile organic compounds (VOC's), yet combine powerful solvency with a low order of toxicity, low volatility, high flash points, and rapid biodegradability.

Citroflex A-4 is widely used in food contact polymers. It provides many improvements over dibutyl phthalate in cellulose nitrate films, including lower volatility, better resistance to yellowing, and better adhesion to metals. Citroflex A-4 is effective in solution coating both paperboard and foil. It is an excellent plasticizer for vinyl toys.
