Abstract
Polyvinyl chloride plastics (PVC), made flexible through the addition of di-2-ethylhexyl phthalate (DEHP) also known as di- octyl phthalate (DOP), are used in the production of a wide array of medical devices, toys, etc. During the past many years, concern has been voiced by public interest groups and regulatory agencies in Europe, Canada, and the United States regarding the potential adverse health effects of DOP migrating from children’s toys during mouthing activities. Concern has focused on potential chronic effects on the kidney and liver. Therefore, phthalate based plasticizers are facing ban in majority of the countries owing to its carcinogenic properties. Hence, the use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market. Many modified vegetable oils are being used as partial replacement of DOP, but none of them has the historical record of acceptable performance comparable with phthalate plasticizers.
