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 2 , the commercial grade, is recommended as a plasticizer for cellulosic derivatives as well as natural resins such as dammar and ester gums. Due to its limited oil solubility, grease resistance of polymers formulated with Citroflex 2 is enhanced. Citroflex 2 also imparts improved light-fastness to lacquer formulations.
