Applicant's summary and conclusion
- Executive summary:
The acute oral toxicity of the test item was evaluated in a GLP-compliant study on male and female Wistar rats. The acute oral LD50 was determined with > 2000 mg/kg bw. As clinical signs temporarily increased salivation and breathing sounds were observed which disappeared up to day 3 after treatment.
