Richard H McKee et al.
Reproductive toxicology (Elmsford, N.Y.), 21(3), 241-252 (2005-10-27)
Di-isoheptyl phthalate (DIHP) is a branched, phthalate ester with seven carbon alkyl side chains. Since structurally similar phthalates have been shown to produce developmental and/or reproductive effects in rodents, the potential for DIHP to produce developmental and reproductive toxicity was...
Fumiyuki Nakane et al.
The Journal of toxicological sciences, 37(3), 527-537 (2012-06-13)
The 26-week oral toxicity of diheptyl phthalate (DHP), a peroxisome proliferator-activated receptor α (PPARα) agonist, with special emphasis on the potential induction of hepatocellular proliferative lesions was investigated in this study. DHP was administered to male F344 rats via gavage...

Eisei Shikenjo hokoku. Bulletin of National Institute of Hygienic Sciences, (110)(110), 26-31 (1992-01-01)
A twenty-eight day repeated oral dose toxicity test of dihepthyl phthalate (DHP) was carried out in male and female F344 rats at the dose levels of 0, 0.2, 1 and 5 g/kg/day. All rats in each group, consisting of 5...
Meilan Jin et al.
Toxicology, 264(1-2), 16-25 (2009-08-01)
To investigate possible potential inducing preneoplastic lesions in liver and in vivo genotoxic potential of diheptyl phthalate (DHP), male F344 rats were subjected to repeated oral administration of DHP at 0, 2.5 or 5 g/kg/day for 28 days. In addition...

Food additives and contaminants, 22(8), 768-782 (2005-09-09)
The gas phase transfer of substances from carton board (CB) and corrugated box board (CBB) through intervening layers to foods was studied. Substances covering a boiling point range of 252-425 degrees C and a range of polarities were incorporated into...
