The irritation effects had cleared completely in 2/3 rabbits within 48 hours and in the remaining rabbit within 72 hours. No damage to the iris or cornea was observed at any reading time point.
- Other effects:
- There was no mortality and no signs of toxicity were observed during the study period. The body weight gains were within the normal ranges during the study period.
