Bis-Diglyceryl Polyacyladipate-2 The reproductive toxicity potential of bis-diglyceryl polyacyladipate-2 was determined in a one-generation study using groups of 24 male and 24 female Sprague-Dawley rats.17 The male animals were dosed daily by gavage with 0 or 1000 mg/kg bw bis-diglyceryl polyacyladipate-2 in corn oil from 10 wks prior to mating until the day before being killed (day 99), and the female rats were dosed by gavage with the same doses from 2 wks prior to mating until weaning and were killed day 21 following delivery. The dose volume was 10 ml/kg bw. The litters were culled on day 4, and the remaining 8 pups/litter were killed on day 21. Bis-diglyceryl polyacyladipate-2 had no effects on reproduction, fertility, or development, and no signs of general toxicity were observed
