Citroflex™ 2 Plasticizer (Triethyl Citrate)

Our Citroflex™ esters are based on natural citric acid raw material, which is mainly derived from the fermentation of corn. The esters have a long history of use in food and beverage, flavoring, medical, and pharmaceutical applications.

Citroflex™ 2 or C-2 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.  It also imparts improved lightfastness to lacquer formulations. 

Polymer compatibility is good with many polymers including: acrylic, methacrylic, ethylcellulose, hydroxymethyl cellulose, nitro cellulose, vinyl acetate, vinyl chloride, vinylpyrrolidone, vinylidene chloride and urethanes.

Citroflex™ esters offer formulators a unique combination of environmentally friendly features. They are neither “Volatile Organic Compounds” (VOCs) nor “Hazardous Air Pollutants” (HAPs) and combine efficient plasticization of polymers with low toxicity, high flash points and rapid biodegradability. Citroflex™ 2 does not support fungal growth.
