    Description

    Bis(2-ethylhexyl) phthalate (di-2-ethylhexyl phthalate, diethylhexyl phthalate, DEHP; dioctyl phthalate, DOP), is an organic compound with the formula C8H4(C8H17COO)2. DEHP is the most common member of the class of phthalates which are used as plasticizers. It is the diester of phthalic acid and the branched-chain 2-ethylhexanol. This colorless viscous liquid is soluble in oil, but not in water. Accounting for an almost 54% market share in 2010, DEHP is a High Production Volume Chemical.
