Dr. Brandon Boor, … WebDi(2-ethylhexyl)phthalate, also known as DEHP, is an organic ester containing an eight-carbon alcohol moiety widely used as a plasticizer in polymers. DEHP is widely used for a variety of standard products due to its overall performance characteristics, including fusion rate, efficiency, and viscosity (Cadogan and Howick 2001; TURI 2006). Phthalates , or phthalate esters, are esters of phthalic acid. They are mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity.
