Di(2-ethylhexyl) phthalate, commonly abbreviated as DEHP, is a synthetically produced chemical extensively used as a plasticizer – a substance added to plastics to increase their flexibility, transparency, durability, and longevity. DEHP is a colorless liquid that is virtually odorless.In practical applications, DEHP is found in a wide array of plastic  products. These include items such as wall coverings, tablecloths, floor tiles, furniture upholstery, shower curtains, garden hoses, swimming pool liners, rainwear, baby pants, dolls, some toys, shoes, car upholstery and convertible tops, as well as in packaging materials like film and sheets. It is also used in the insulation sheathing for wire and cable, medical tubing, and blood storage bags. Chemically, DEHP is known as bis(2-ethylhexyl) phthalate. It is a phthalate ester, specifically the bis(2-ethylhexyl) ester of benzene-1,2-dicarboxylic acid. In addition to its use as a plasticizer, DEHP has roles as an apoptosis inhibitor and an androstane receptor agonist. It is a diester belonging to the class of phthalates, which are widely utilized as plasticizers in the manufacturing of plastics. DEHP, with the chemical formula C6H4(CO2C8H17)2, is the most common member of the phthalate class. It is produced by the esterification of phthalic acid with branched-chain 2-ethylhexanol. This colorless and viscous liquid is soluble in oil but insoluble in water. Due to its widespread use in plastic production, DEHP is a significant chemical in the plastics industry, particularly in applications requiring increased plastic flexibility.
