Executive summary:

The study was performed to assess the acute oral toxicity of the test material following a single oral administration in the Sprague-Dawley Crl:CD (SD) IGS BR rat. The method followed OECD guideline 423 "Acute Oral Toxicity - Acute Toxic Class Method" (adopted 22 March 1996), EU Commission Directive 96/54/EEC Method B1 tris Acute Oral Toxicity (Oral Acute Toxic Class Method).

A group of three fasted females was treated with 2000 mg/kg bodyweight; this was followed by a group of three fasted animals of the other sex at the same dose level. The test material was administered orally as a suspension in arachis oil BP. Clinical signs and bodyweight development were monitored during the study. All animals were subjected to gross necropsy examination.

No deaths occurred and no signs of toxicity were noted during the study. Individual necropsy did not revealed any abnormality.

Conclusion

LD50 (male and female) > 2000 mg/kg bw
