There was no evidence that the test substance is teratogenic to
the rat at any of the dose levels tested (up to 12000 ppm -approximately
1000 mg/kg/day). Administration of 12000 ppm DEHA resulted in slight
maternal toxicity and slight foetotoxicity.
At 1800 ppm, there was no evidence of maternal toxicity although
minimal foetotoxicity was observed. A dietary level of 300 ppm DEHA was
a clear no-effect level for embryonic development.
