It is soluble in hydrocarbon compounds, ketones, esters, higher grade alcohols and other organic solvents, slightly soluble in ethanol as well.

It is the most widely used PVC nontoxic plasticizer and stabilizer. It 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 it the internationally acknowledged chemical aid for foodstuff wrapper. It 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. It can also be applied to making special printing ink, oil paint, coating material, synthetic rubber, and liquid compound stabilizer and so on.

Jointly used with polyester plasticizers, it can reduce their mobility, while with metal heat stabilizers, it would greatly enhance their stability, and the dosage of these metal stabilizers necessary can be reduced to only one third of that used alone. As far as compatibility with PVC, ESO is equivalent to DOP and is better in terms of plasticizing efficiency. Thus the total need of plasticizers would be less. It does not only bring down the cost, but also improves the technical standard of our products, such as the tolerance of impact, transparency, printability, weld ability and so on. 5~10 portion of ESO would remarkably ameliorate the heat and light stability of soft products. Under special situation, 10~30 portion of ESO used non-open-air, no other stabilizers is necessary. The addition of this chemical, will cut down the amount of other plasticizers, stabilizers and lubricants needed.
