Manufacturing process
ESBO Epoxidized Soybean Oil is manufactured from soybean oil through the process of epoxidation.
Polyunsaturated vegetable oils are widely used as precursors to epoxidized oil products because they have high numbers of carbon-carbon double bonds available for epoxidation.
The epoxide group is more reactive than double bond, thus providing a more energetically favorable site for reaction and making the oil a good hydrochloric acid scavenger and plasticizer. Usually a peroxide or a peracid is used to add an atom of oxygen and convert the -C=C- bond to an epoxide group.
Uses
Food products that are stored in glass jars are usually sealed with gaskets made from PVC.
ESBO Epoxidized Soybean Oil is one of the additives in the PVC gasket.
ESBO Epoxidized Soybean Oil serves as a plasticizer and a scavenger for hydrochloric acid released when the PVC degrades thermally, e.g. when the gasket is applied to the lid and food product undergoes sterilization.
ESBO Epoxidized Soybean Oil is also used in PVC cling films for wrapping foods and toys.
Applications:
ESBO Epoxidized Soybean Oil is the most widely used PVC nontoxic plasticizer and stabilizer.
ESBO Epoxidized Soybean Oil is particularly consistent with PVC and has low volatility and mobility.
Its high thermal stability, light stability and good resistance to water and oil endow the products with better mechanical strength, weather resisting property and electrical property.
Its non-toxicity makes ESBO Epoxidized Soybean Oil the internationally acknowledged chemical aid for foodstuff wrapper.
ESBO Epoxidized Soybean Oil can be applied to all PVC products, such as, foodstuff wrapper, medical ware, pellicle, sheet material, tubular goods, sealing plate of icebox, artificial leather, floor leather, wire and cable material, plastic wallpaper and other daily use plastic products.
ESBO Epoxidized Soybean Oil can also be applied to making special printing ink, oil paint, coating material, synthetic rubber, and liquid compound stabilizer and so on.

Industrial Applications
PVC Processing (Flexible & Rigid)
ESBO is primarily incorporated into Polyvinyl Chloride (PVC) formulations.
ESBO Epoxidized Soybean Oil acts as an auxiliary plasticizer alongside primary plasticizers (like DOTP, DINP, or DOA) to optimize cost and performance.
Food Contact Materials: Due to its food-grade, non-toxic approval, ESBO Epoxidized Soybean Oil is the globally accepted standard additive for PVC food wrap films, jar lid sealants, and beverage tubing.
Medical Ware: Extensively utilized in blood bags, intravenous (IV) tubes, and medical gloves where toxic phthalate plasticizers must be minimized or avoided entirely.
Consumer Goods: Found in artificial leather, floor coverings, automotive interiors, wires, cables, and plastic wallpapers.
Non-PVC Applications
Pigment Dispersing: Serves as an effective grinding medium and dispersion agent for pigments in paints, coatings, and plastics.
Chemical Intermediates: Used as a reactive building block or functional raw material to formulate UV-curable resins, polyurethanes, epoxy coatings, and eco-friendly printing inks.
Core Functions & Properties
Plasticizer: ESBO Epoxidized Soybean Oil makes rigid plastics like PVC flexible and durable.
Stabilizer: ESBO Epoxidized Soybean Oil acts as an acid scavenger, absorbing hydrochloric acid released during the heat treatment of PVC to prevent degradation.

Safety
Food
A Swiss survey in June 2005 showed that (among many other plasticizers exceeding the legal limits) migration of ESBO into foods reached up to 1,170 mg/kg.
Rapid Alert System in Food and Feed (RASFF) had also reported cases of food product rejection in EU for exceeding specific migration limit (SML) under EU Legislation (EC/2002/72).
Enforcement authorities took measures to force producers respecting the legal limits.
Legislation
In Europe, plastics in food contact are regulated by Regulation (EU) 10/2011.
ESBO Epoxidized Soybean Oil establishes a SML for ESBO of 60 mg/kg. However, in the case of PVC gaskets used to seal glass jars containing infant formulae and follow-on formulae as defined by Directive 2006/141/EC or processed cereal-based foods and baby foods for infants and young children as defined by Directive 2006/125/EC, the SML is lowered to 30 mg/kg.
This is because babies have higher food consumption per body weight.
Toxicity
The tolerable daily intake (TDI) of ESBO Epoxidized Soybean Oil defined by the Scientific Committee on Food (SCF) of the EU is 1 mg/kg body weight.
This value is based on a toxicological assessment performed by the British Industrial Biological Research Association (BIBRA) in the late 1997.
Repeated oral administration had been shown to affect the liver, kidney, testis and uterus of rats.
According to the conventional European rules for food packaging materials, the TDI became a basis for the SML of 60 mg/kg.
