DescriptionBis(2-ethylhexyl) phthalate, also known as di-iso-octyl phthalate or DEHP, belongs to the class of organic compounds known as benzoic acid esters. These are ester derivatives of benzoic acid. Bis(2-ethylhexyl) phthalate is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Bis(2-ethylhexyl) phthalate is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. DEHP is found in Aloe vera, Aucuba japonica, Bulbophyllum odoratissimum, Chromolaena odorata, Cryptotaenia canadensis, Garcinia yunnanensis, Penicillium, Penicillium olsonii, Pterocarpus angolensis, Pueraria montana, Scutellaria baicalensis, Streptomyces bangladeshensis and Streptomyces coeruleorubidus. DEHP was first documented in 1994 (PMID: 8150716). Based on a literature review a small amount of articles have been published on Bis(2-ethylhexyl) phthalate (PMID: 12963402) (PMID: 16874505) (PMID: 17286146) (PMID: 19211671).
