Application of Bis(2-ethylhexyl) phthalate
Bis(2-ethylhexyl) phthalate, known by a variety of other names and usually abbreviated DEHP, was patented in 1950 and first used as vacuum pump oil. But since then, it has become the most widely used plasticizer for poly(vinyl chloride) (PVC) and other plastics. Recently, relatively high levels of DEHP have been found in foods, especially foods high in oils and fats. The U.S. Food and Drug Administration now restricts its use in packaging materials to water-based foods. The European Commission has banned the use of DEHP and other phthalates in PVC toys.
Di(2-ethylhexyl)phthalate (DEHP) is a benzenedicarboxilate ester which is the most widely used plasticizer to soften resins. DEHP is hydrolyzed into what many believe to be its toxic metabolite, mono(2-ethylhexyl)phthalate (MEHP), by lipase enzymes in the gastrointestinal tract.
Bis(2-ethylhexyl) phthalate is commonly used plasticizing agent for PVCs, which as such is a component of blood bank bags, surgical tubing, and other products including food wrappers and children’s toys.
