What is Epoxidized Soybean Oil (ESO) & It’s Uses?

Today, we are going to talk about Epoxidized soybean oil, or ESO, and its uses.

ESO is produced when soybean oil is combined and goes through a chemical reaction of epoxidation. Vegetable oils are often used to combine with chemicals as they have a very high number of double bonds of carbon-carbon.

Please continue reading to understand the process of how epoxidized soybean oil is made and its various uses in different industries. Let’s start.

About Epoxidized Soybean Oil

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:

• Sheet materials
• Sealing slips of refrigerators
• Artificial tubing
• Making packaging material
• Plastic wallpaper
• Artificial leather, and so on

Uses of Epoxidized Soybean Oil or ESO

ESO is readily available for industrial uses at a meager price because soyabean oil is also a low-cost vegetable oil that is easily available across the globe. ESO has been uickly replacing DOP for various applications as it is environmentally friendly and non-toxic.

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:
• Mercaptan/acid scavenging agent
• Reactive diluent
• Pigment dispersing agent

Lastly, epoxidized soybean oil is used in the form of raw material for various purposes such as pharmaceutical and agricultural molecules, functional fluids, polyol replacements, fuel additives, surfactants, coatings, sealants, special inks, and adhesives.

Conclusion
ESO’s primary use is as a plasticizer and stabilizer in PVC plastic. We have also explained its various uses as a raw material in different products. Now that you’re done reading our article on epoxidized soybean oil, we hope you understand what it is and how it is used in the industry.
