Irritant / corrosive response data:
1. As a result of observing the test substance administration site, skin irritation and corrosiveness were not observed in all the test substance the administration and control sites.
2. Evaluation of skin irritation scores at 24, 48 and 72 hours after administration of test substance resulted in a skin irritation score of "0.0" for erythema & edema and edema in all animals.
Other effects:
1. No mortality was observed in this study.
2. No treatment-related clinical signs were observed in any treated animals.
3. All tested animals observed normal gains in body weights.
