Metabolite Identification
Common NameMono-benzyl phthalate
DescriptionMono-benzyl phthalate, also known as benzene-1,2-dicarboxylic acid, monobenzyl ester or benzyl hydrogen phthalate, is a metabolite of butyl benzyl phthalate (BBzP). It can be found in human biofluids. Phthalates are industrial chemicals that are added to plastics to impart flexibility and resilience and are often referred to as plasticizers. Phthalates also are used as solubilizing or stabilizing agents in other applications. There are numerous products that may contain phthalates: adhesives; automotive plastics; detergents; lubricating oils; some medical devices and pharmaceuticals; plastic raincoats; solvents; vinyl tiles and flooring; and personal-care products, such as soap, shampoo, deodorants, lotions, fragrances, hair spray, and nail polish. Phthalates are often used in polyvinyl chloride type plastics, such as plastic packaging film and sheet, garden hoses, inflatable recreational toys, blood product storage bags, intravenous medical tubing, and toys. Because they are not chemically bound to the plastics to which they are added, phthalates can be released into the environment during use or disposal of the product. People are exposed to phthalates through ingestion, inhalation, and, to a lesser extent, dermal contact with products that contain phthalates. Phthalates have low acute animal toxicity. In animals, phthalates produced anti-androgenic effects by reducing testosterone production and, at very high levels, reducing estrogen production, effects that may be mediated by inhibiting testicular and ovarian steroidogenesis.
