Executive summary:

The test substance is a fine white powder. It was tested regarding its acute toxic potential following single oral application according to the OECD guideline No. 401 in a limit test with a dose of 2000 mg/kg body weight. The test substance was applied as 20 % dispersion in water by gavage to 5 male and 5 female rats. No symptoms of toxicity were observed, no death occured during the 14 day observation period. Body weight gain was in the normal range and necropsy revealed no visible compound related macroscopic findings.

The LD50 -value for acute oral toxicity is > 2000 mg/kg body weight.
