The acute oral LD50 in male rats ranged from 128 mg/kg to greater than 5,000 mg/kg depending on the carrier and conditions of the study.The acute percutaneous LD50 for rats was reported to be greater than 2,000 mg/kg. The acute dermal LD50 for rabbits was greater than 2,000 mg/kg. No skin irritation and slight eye irritation were reported.
