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 light-fastness to lacquer formulations. In the personal care area, C-2 is used as a fixative for perfumes and as a plasticizer and film strengthening agent in hair sprays, nail polishes, and as an active in deodorants. Citroflex® 2 does not support fungal growth.
The lower molecular weight citric acid esters (Citroflex C-2, A-2, C-4, and A-4) have plasticization characteristics similar to those of the lower molecular weight phthalates, adipates, and sebacates in a variety of polymers.
