1. The hydrolysis of di(2-ethylhexyl) terephthalate (DEHT) and di(2-ethylhexyl) phthalate (DEHP) were studied using rat gut homogenate fractions in vitro. Both isomers were hydrolysed by the intestinal fraction; however, DEHP was hydrolysed to 2-ethylhexanol (2-EH) and mono(2-ethylhexyl) phthalate (MEHP) in

The carcinogenicity and chronic toxicity potential of di-2-ethylhexyl terephthalate (DEHT) was assessed in F-344 rats (50/sex/dose) by dietary exposure for 104 weeks. Exposure levels of 0, 1500, 6000 or 12,000 ppm resulted in average daily doses of 79, 324 and

Possible human health effects of phthalate plasticizers have been intensely discussed during the last decade. Di(2-ethylhexyl) phthalate (DEHP), the phthalate acid ester with the largest production volume worldwide, has been substituted by new compounds like Diisononyl 1,2-cyclohexanedicarboxylic acid (DINCH) or

Groups of five male and five female rats were fed diets containing from 0% to 2.5% di(2-ethylhexyl)terephthalate (DEHT) or 1.2% di(2-ethylhexyl)phthalate (DEHP) for 21 days. Feed consumption and body weight gains were collected and, at study termination, animals were examined
