Executive summary:

Two groups, each of three female HanRcc:WIST (SPF) rats, were treated with TRIQUAT MONOMER by oral gavage administration at a dosage of 2000 mg/kg body weight in terms of the active ingredient. The test item was diluted in vehicle (purified water) at a concentration of 0.476 g/mL and administered at a dosing volume of 10 mL/kg.

The animals were examined daily during the acclimatization period and mortality, viability and clinical signs were recorded. All animals were examined for clinical signs within the first 30 minutes and approximately 1, 2, 3 and 5 hours after treatment on day 1 and once daily during test days 2-15. Mortality/viability was recorded at approximately 30 minutes, 1, 2, 3 and 5 hours after administration on test day 1 (with the clinical signs) and twice daily during days 2-15. Body weights were recorded on day 1 (prior to administration) and on days 8 and 15. All animals were necropsied and examined macroscopically.

All animals survived until the end of the study period. No clinical signs were observed during the course of the study. The body weight of the animals was within the range commonly recorded for this strain and age. No macroscopic findings were recorded at necropsy. The median lethal dose of TRIQUAT MONOMER (active ingredient) after single oral administration to female rats, observed over a period of 14 days is: LD50 (female rat): greater than 2000 mg/kg body weight.

Based on the results of this study, the test substance TRIQUAT MONOMER (active ingredient) is not classified according to the criteria of Annex VI of Directive 67/548/EEC and EU GHS.
