Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The test material was determined to have a acute oral toxicity LD50 of >5000 mg/kg bw in the rat, under the conditions of the test.
Executive summary:

Ten (5M:5F) albino rats, 200 -280g, each received a single dose of the test article at a dose level of 5g/kg bw. Animals were observed for pharmacologic activity and drug toxicity 1, 3, 6, and 24 hours adfter treatment, and daily thereafter for a total of 14 days. Non-survivors and animals surviving the 14 day obnservation period were subject to gross necropsy, with all findings noted. The test article was used as received (Sp.g. = 0.83).

LD50: 5 g/kg bw (5000 mg/kg bw)

This test article is not toxic orally to rats under the conditions of the test.
