Common NameDioctyl phthalate
DescriptionDioctyl phthalate or Di(n-octyl) phthalate or DOP, also known as diethylhexyl phthalate or DEHP is a dialkylated derivative of phthalate in which two n-octyl groups have been replaced by hydrogen atoms of carboxyl groups. Dioctyl phthalate belongs to the class of organic compounds known as benzoic acid esters. These are ester derivatives of benzoic acid. It is also classified as a diester of phthalic acid and the branched-chain 2-ethylhexanol. Dioctyl phthalate or DEHP exists as a colorless, odorless oily liquid that is slightly soluble in water. Industrially, due to its suitable properties and the low cost, DEHP is widely used as a plasticizer in manufacturing of articles made of PVC (polyvinylchloride). Plastics may contain 1% to 40% of DEHP. It is also used as a hydraulic fluid and as a dielectric fluid in capacitors. DEHP is also used as a solvent in glowsticks. DEHP is a component of many household items, including tablecloths, floor tiles, shower curtains, garden hoses, rainwear, dolls, toys, shoes, medical tubing, furniture upholstery, and swimming pool liners. DEHP is an indoor air pollutant in homes and schools. Common exposures come from the use of DEHP as a fragrance carrier in cosmetics, personal care products, laundry detergents, colognes, scented candles, and air fresheners. The most common exposure to DEHP comes through food with an average consumption of 0.25 milligrams per day. When DEHP is ingested intestinal lipases convert it to MEHP (mono-ethylhexyl phthalate), which then is absorbed. MEHP is suspected to have an obesogenic effect. DEHP, along with other phthalates, is believed to cause endocrine disruption in males, through its action as an androgen antagonist. Di(n-octyl) phthalate or DEHP has been found in a small number of plants such as kohlrabis. It has also been found as a contaminant in milk, cream, butter and cheese (PMID: 7926171 ). Dioctyl phthalate is a constituent of cannabis smoke and is formed during the combustion of cannabis ( Ref:DOI ).
