Epoxidised Soybean Oil (ESBO)

About This Product

Epoxidised soybean oil, CAS 8013-07-8, is made by treating soybean oil with peracid so the double bonds in its unsaturated fatty acid chains are converted into epoxide rings. It is supplied as a light yellow sticky oily liquid. It performs two jobs at once, which is unusual. As a plasticiser the triglyceride structure separates PVC chains and gives flexibility in the ordinary way. As a secondary stabiliser the epoxide rings open to consume hydrogen chloride as it is released, and also scavenge the zinc chloride that causes mixed-metal systems to fail suddenly. That is why ESBO is a near-universal component of calcium-zinc and barium-zinc formulations rather than an alternative to them. It is bio-based and has broad regulatory acceptance in food contact, which explains its declared applications: transparent bottles, food packaging, medical blood transfusion bags and waterproof rolls. Some grades are described for chewing gum base and cosmetic plasticiser applications. Our team must confirm the offered grade's documentation and suitability before ordering for these uses.
