Epoxidized Soybean Oil Plasticizer or ESBO is made when soyabean oil goes through the epoxidation process, which increases its reactivity compared to the carbon-carbon double bond. When epoxidized, the soyabean oil turns into a suitable plasticizer and hydrochloric acid scavenger.

ESO is a liquid that is yellow in color, and it is used in PVC plastics in the form of a stabilizer and plasticizer. ESO is also used in compounds, gaskets, films, masterbatches, etc. for manufacturing various products, including:
1) Sheet materials
2) Sealing slips of refrigerators
3) Artificial tubing
4) Making packaging material
5) Plastic wallpaper
6)Artificial leather

Uses of Epoxidized Soybean Oil or ESO

When we talk about the uses of ESO, it is mainly used as an epoxidized soybean oil plasticizer and stabilizer in PVC plastic, its copolymers, and various other plastics. ESPO adds to the flexibility and softness of these plastics.

Epoxidized soybean oil is used to make glass jars that are used for food storage as these jars have gaskets to seal them, which are made using PVC. PVC cling films also include ESO in them.

ESPO is also an integral chemical used as a:
1) Mercaptan/acid scavenging agent
2) Reactive diluent
3) Pigment dispersing agent
