Application

Epoxidized Soybean Oil (ESO) is produced through the oxidation of high iodine value unsaturated soybean oil with hydrogen peroxide and organic acids such as acetic acid or formic acid. ESO is primarily used as a co-plasticizer for flexible polyvinyl chloride (PVC) and its copolymers. It also acts as a secondary heat and light stabilizer, and it is especially valuable as a low cost and effective synergist to metallic stabilizer compounds in vinyl systems. Acting as a polymeric type plasticizer due to its high molecular weight, it resists migration, volatilization, and extraction. In addition, ESO acts as an acid scavenger for soy-based inks, agricultural chemicals, and insecticides. ESO can be used as a pigment dispersion agent, chemical intermediate, additive for specialty coatings, adhesives, and urethanes, and in lubricants and cutting oils. ESO is compatible with PVC, Chlorinated rubber, ethyl cellulose, nitrocellulose, polyvinyl acetate, and some alkyds. ESO is also approved by the FDA for use as an indirect food additive for food contact surfaces. Because ESO is non-toxic, bio-based, bio-degradable, and phthalate-free, it is a prime choice for sustainable and eco-friendly formulations.
