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

Exposure of pubertal rats to di-(2-ethylhexyl) phthalate (DEHP) for 14 days was reported to result in reduced testosterone (T) biosynthesis by altering androstenedione 17beta-hydroxysteroid dehydrogenase (17beta-HSD) activity. However, our study indicated that shorter period exposure of DEHP (100 or 1000

Di-2-ethylhexyl-terephtalate (DEHT) is a general purpose plasticizer and a structural isomer to di-2-ethylhexyl phthalate (DEHP) being known for its toxicity. Despite the fact that DEHT is used in quite a number of synthetics for medical device production including equipment for

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
