Epoxidized Soybean Oil (ESO)

DESCRIPTION

Epoxidized Soybean Oil (ESO) is a versatile chemical produced by the oxidation of high iodine value unsaturated soybean oil using hydrogen peroxide and organic acids like acetic or formic acid. One of its main applications is as a co-plasticizer for flexible polyvinyl chloride (PVC) and its copolymers, where it enhances flexibility and acts as a secondary heat and light stabilizer. In addition, ESO is a cost-effective synergist to metallic stabilizer compounds in vinyl systems, making it a valuable component in many formulations. Its high molecular weight also makes it an effective polymeric type plasticizer, as it resists migration, volatilization, and extraction. ESO has other applications as well, such as an acid scavenger for soy-based inks, agricultural chemicals, and insecticides, and as a pigment dispersion agent, chemical intermediate, and additive for specialty coatings, adhesives, urethanes, and lubricants and cutting oils. It is compatible with PVC, chlorinated rubber, ethyl cellulose, nitrocellulose, polyvinyl acetate, and some alkyds. Furthermore, ESO is FDA-approved for use as an indirect food additive for food contact surfaces, making it a safe choice for many applications. What makes ESO an especially attractive choice for many industries is that it is non-toxic, bio-based, bio-degradable, and phthalate-free, making it a sustainable and eco-friendly option for formulations. In summary, Epoxidized Soybean Oil is a versatile chemical with multiple applications and benefits, making it a valuable component in many formulations.
