Toxicity evaluation

In the rat, the acute oral LD 50 was reported to be > 36.3 g/kg (Jenner, Hagan, Taylor, Cook & Fitzhugh, 1964). At this dose, the highest tested, toxic signs included depression, wet fur and diarrhoea, but the surviving animals appeared normal after 1 wk. In the mouse, the acute oral LD 50 was 151 g/kg (Jenner et al. 1964); animals were depressed soon after treatment and excitable after 1 hr, with rough fur, and death occurred between 4 hr and 3 days. The acute dermal LD 50 in rabbits was reported as > 5 g/kg (Moreno, 1974).
