Abstract

A 28-day repeated dose toxicity test and reproduction/developmental toxicity test for N,N'-diphenyl-p-phenylenediamine (DPPD) were conducted in [Crl:CD(SD)] SPF rats. Male and female rats were dosed with DPPD by gavage for 28. days at 0, 100, 300, or 1000. mg/kg bw/day or for a total of 42-46. days at 0, 8, 50, or 300. mg/kg bw/day. No significant adverse effects were observed in the repeated dose toxicity study up to 1000. mg/kg bw/day in both sexes. In the reproduction/developmental toxicity study, two females showed piloerection, hypothermia, and pale skin; one died and the other showed dystocia on day 23 of pregnancy at 300. mg/kg bw/day. Another female delivered only three live pups at 300. mg/kg bw/day. A significantly prolonged gestation period was observed at 50 and 300. mg/kg bw/day. The NOAELs of repeated dose toxicity and reproduction/developmental toxicity were considered to be 1000 and 8. mg/kg bw/day, respectively.
