Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
None of the animals died and no signs of intoxication were observed. LD50 > 5000 mg/kg bw (rat, male). According to CLP classification criteria (Regulation (EC) No 1272/2008) a classification is therefore not justified.
Executive summary:

One group of 10 male Wister rats (average weight 160-180 g) received per gavage a single dose of 5000 mg/kg bw Chinizarin techn. tr.. The animals were observed for mortality and clinical signs through day 14. None of the animals died and no signs of intoxication were observed. LD50 > 5000 mg/kg bw (rat, male).
