Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The limit test for oral toxicity in the rat did not show any toxic effects up to a dose of 5000 mg/kg bw.
Executive summary:

The study was conducted according to Guideline EU B.1 and was designed as a limit test.

A single dose of 5000 mg/kg bw of the substance in CMC (carboxymethyl cellulose) was administered to rats by the oral route.

After the application, the animals showed tousled fur for the rest of the day. No signs of toxicity were observed for the duration of the study.
