Professional R&D and excellent quality plasticizer chemicals

Epoxidized soybean oil (ESO) is one of the bio-based plasticizers, which has attracted the general attention due to its low toxicity and inherent biodegradability [ 16, 17 ]. It is commonly used in epoxy, polyvinyl chloride, chloroprene rubber, and butadiene-acrylonitrile rubber to improve the properties of stability and flexibility [ 18 ].

Vegetable oils such as epoxidized soybean oil (ESO) are not recyclable and cannot be reprocessed due to the cross-links in their structure (Liu et al. 2025b) ESO is preferred as a plasticizer and

Synthesis of acetylated castor oil (ACO) Castor oil (93.4 g) and acetic anhydride (27.5 g) were added to a 500 mL four-necked flask, and were stirred at 140 °C for 2 h. Then the reaction mixture was washed to pH = 7 with sodium carbonate solution and distilled water. Then the water was removed by vacuum distillation.

A novel environmental soybean oil‐based plasticizer, epoxidized glycidyl ester of soybean oil fatty acids (EGESOFa), was synthesized and characterized by Fourier transform infrared...

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.
