Diisooctyl phthalate (C24H38O4) is an exogenous organic compound with an average molecular weight of 390.56 g/mol. It exists as a liquid at room temperature. Diisooctyl phthalate belongs to the benzoic acids and derivatives, a subclass of benzene and substituted derivatives within the organic compounds. Industrially, the compound is used as a plasticizer.
The substance is released from polyvinyl chloride and polypropylene, and it is present in polystyrene and polyethylene terephthalate. Its presence in polycyclohexylenedimethylene terephthalate, polyurethane, and polyamide remains inconclusive. Diisooctyl phthalate is found in or released from 15 recorded sources. Within building and construction, it is associated with ceilings, fencing, roofs, and sunshades, awnings or outside screens. In electrical and electronic equipment, it is linked to antennas, discharge lamps, fixed capacitors and their manufacture, as well as communication and power cables. It is also found in indoor air, as well as in food, food processing and cookware, specifically regarding the processing of meats, processing of fish, and fermentation processes for beer. Inhalation is a recorded route of exposure.
Phthalate esters are endocrine disruptors. They decrease foetal testis testosterone production and reduce the expression of steroidogenic genes by decreasing mRNA expression. Some phthalates have also been shown to reduce the expression of insulin-like peptide 3 (insl3), an important hormone secreted by the Leydig cell necessary for development of the gubernacular ligament. Animal studies have shown that these effects disrupt reproductive development and can cause a number of malformations in affected young. (2)
