Name:  Epoxidized soya bean oil

Other names: ESBO, ESO

CAS Registry Number:  8013-07-8

EINECS 232-391-0

Epoxidized Soybean oil is the most readily available and one of the lowest-cost vegetable oils in the world. Epoxidized soybean oil is the result of the oxidation of soybean oil with hydrogen peroxide and either acetic or formic acid. ESO is industrially available in large volume at a relatively low price.

Due to its low cost and biodegradability over traditional phthalate plasticizers, ESO is replacing dioctyl phthalate (DOP) in some applications.

Epoxidized soybean oil (ESO) is used as a plasticizer and stabilizer in plastic materials, especially PVC and its copolymers to keep these plastics soft and pliable.

The chemical is also used as a pigment dispersing agent and acid mercaptan scavenging agent as well as an epoxy reactive diluent.

Due to its low cost non-toxic and environmentally friendly properties, as well as its biodegradability over traditional phthalate plasticizers, ESO is replacing dioctyl phthalate (DOP) in some applications.

Epoxidized soybean oil is also used as a pigment dispersing agent and acid/mercaptan scavenging agent as well as an epoxy reactive diluent. epoxidized soybean oil and other epoxide substances are used as raw materials for various applications that include functional fluids, fuel additives, polyol replacements, agricultural and pharmaceutical molecules, flavor and fragrances, reactive diluents and UV cure applications, surfactants, adhesives, sealants, coatings, and special inks.
