Not only are the plasticizers in poly(vinyl chloride) plastics toxic in production and disposal, but are also non-biodegradable and pose potential environmental and health risks through leaching. We replaced the common di(2-ethylhexyl) phthalate primary plasticizer with peanut oil and propylene glycol. Peanut oil is a possible organic vegetable oil plasticizer, and propylene glycol a biodegradable but synthetically produced one. After making PVC film sheets, we measured clarity, flexibility and compression. While peanut oil had little to no plasticizing effect, propylene glycol was worthy of consideration since it outperformed DEHP in flexibility in samples of 20% concentration.
