Interpretation of results:
GHS criteria not met
Executive summary:

Five male and five female Wistar rats (average weight at the beginning of the study 197 and 174 g, respectively ) received per gavage a single dose of 5000 mg/kg bw Macrolex Blau CA 51056. The animals were observed for mortality, weight and clinical signs through day 14. A gross necropsy was performed on animals killed after the observation period.


A dose of 5000 mg/kg bw was tolerated without symptoms. The LD50 is > 5000 mg/kg bw for male and female rats.
