Test Guidance
US EPA 16 CFR Part 1600.
Method
The test substance was administered by gavage to each of five male and five female Sprague-Dawley rats at a dose level of 5000 mg/kg body weight. The animals were observed for pharmacotoxic signs and mortality for 15 days.
Results
All animals survived the 15 day post-adminstration period.
Conclusion
The test material gave an LD50 value greater than 5000 mg/kg in the rat.
