Request SDS →Epoxidized soybean oil (ESBO, CAS 8013-07-8) is a chemically modified vegetable oil produced by the epoxidation of soybean oil. It is used as a secondary plasticizer and co-stabilizer for polyvinyl chloride, where it also scavenges the hydrogen chloride liberated during PVC processing. It functions as a synergist for mixed-metal heat stabilizers in flexible PVC.
Frequently Asked Questions
What is epoxidized soybean oil (ESBO) used for?
Epoxidized soybean oil (ESBO, CAS 8013-07-8) is used as a secondary plasticizer and co-stabilizer for polyvinyl chloride. During PVC processing it scavenges the hydrogen chloride liberated by the polymer and acts as a synergist for mixed-metal heat-stabilizer systems. It is a bio-based, vegetable-oil-derived plasticizer and stabilizer.
What does 'epoxidized' mean?
Epoxidized means the carbon-carbon double bonds of the soybean oil have been chemically converted to epoxide (oxirane) groups through epoxidation. Those reactive epoxide groups are what let ESBO scavenge hydrogen chloride and act as a PVC co-stabilizer. Oxirane content is a key specification on the CoA.
What is the difference between soybean oil and epoxidized soybean oil?
Plain soybean oil is the unmodified triglyceride; epoxidized soybean oil has had its unsaturated double bonds converted to epoxide groups, giving it the reactivity needed to function as a PVC plasticizer and hydrogen-chloride scavenger. ESBO is characterized by its oxirane oxygen and iodine values. Confirm these specifications on the CoA before ordering.
What grade and identity does RawSource supply?
We supply ESBO referenced to CAS 8013-07-8 under HS 1518.00, with a lot-specific CoA reporting oxirane oxygen, iodine value, and other key specifications. Cite the CAS on RFQs to ensure correct material. Request the current datasheet for the grade quoted.
How is epoxidized soybean oil supplied in bulk?
RawSource supplies ESBO to PVC compounders and plastics manufacturers in drums, IBC totes, and bulk formats. Packaging, MOQ, and specification are confirmed at quotation against the CoA; pricing is provided by quote, not list. Submit a bulk RFQ with your required volume for current availability.
