Epoxidized soybean oil (ESO) is a bio-based plasticizer with huge market development potential in the future.

Epoxidized soybean oil (ESO for short) is a chemical product made from soybean oil after oxidation treatment. It is a light yellow viscous oily liquid at room temperature. It is non-toxic, insoluble in water, and soluble in most organic solvents and hydrocarbons. Epoxidized soybean oil is a resource-rich, environmentally friendly, cheap and non-toxic renewable raw material. It is mainly used as a plasticizer, additive, stabilizer, etc. in food packaging products, polyvinyl chloride products, medical products, wires and cables, etc. Agricultural film and other fields.

The production process of epoxidized soybean oil includes two categories: solvent method and solvent-free method, including peroxyformic acid oxidation method, aluminum sulfate catalytic method, ion exchange resin catalytic method, peroxycarboxylic acid oxidation method, phase transfer catalytic oxidation method, etc. The solvent method production process is long and causes serious environmental pollution. At present, the solvent method production capacity has basically been eliminated by the market. The solvent-free method has the advantages of simple production process, short production cycle, and low raw material consumption, but it also has the disadvantages of poor reaction stability and low epoxy value of the finished product. In the context of upgrading market demand, the production process of epoxy soybean oil has been upgraded. The need is urgent.

According to the “2021-2025 Global Epoxidized Soybean Oil (ESO) Industry In-depth Market Research and Key Area Research Report released by the Industrial Research Center >》shows that epoxy soybean oil is an epoxy plasticizer that was developed and applied earlier. At present, epoxy plasticizers account for about 9% of my country’s plasticizer market, and in carbon neutrality , Carbon peak strategy background, the epoxy plasticizer market has great room for development.

As a less toxic plasticizer, the safety performance of epoxidized soybean oil has been internationally recognized. In foreign markets, epoxidized soybean oil can be directly used in plastic products that come into contact with food. At the same time, epoxidized soybean oil is environmentally friendly and is one of the most commonly used bio-based plasticizers. As environmental protection regulations become increasingly strict, epoxidized soybean oil plasticizers are expected to gradually replace phthalate plasticizers. agent, the future market development space is broad.

my country is rich in oil resources and its soybean oil production ranks among the top in the world. Therefore, my country has raw material and technical advantages in developing epoxidized soybean oil. From the supply side, my country’s epoxidized soybean oil production capacity is mainly concentrated in Shandong, Zhejiang, Guangdong, Jiangsu and other regions. Related production companies include New Jinlong Bio-based Materials, Shandong Huayang Oil Industry Co., Ltd., and Zibo Kailian Chemical Co., Ltd. , Nantong Haierma Technology Co., Ltd., Guangzhou Dongfeng Chemical Industry Co., Ltd., etc.

Industry analysts said that at this stage, environmental protection and sustainable development have become the focus of global attention. Against this background, bio-based The industry has ushered in a good opportunity for development. Epoxidized soybean oil is one of the commonly used bio-based plasticizers at present, and the future market development space is broad. To develop the epoxidized soybean oil industry, my country has raw material and technological advantages. As relevant research continues to deepen, the proportion of epoxidized soybean oil plasticizers in the plasticizer market will continue to increase in the future.
