Reproductive toxicology (Elmsford, N.Y.), 13(2), 131-136 (1999-04-23)
The developmental toxicity of di-isodecyl phthalate (DIDP; CAS RN 68515-49-1) and di-isononyl phthalate (DINP; CAS RN 68515-48-0) were investigated in Sprague-Dawley rats. DIDP and DINP were administered by gavage to mated rats at doses of 0, 100, 500, and 1000

Di-isodecyl phthalate (DIDP) is a commercial plasticizer with low toxicity in many animal studies. The effects of dietary DIDP administration on fertility and developmental parameters were assessed in Sprague-Dawley rats utilizing two generation reproductive toxicity studies generally consistent with current
