- Irritant / corrosive response data:
- At the 1-hour reading time point, 3/3 rabbits had slight-moderate conjunctivae (scores 1, 1, 2) and 2/3 slight chemosis (scores 0, 1, 1). The chemosis had cleared by the 24-hour reading time point, while 3/3 animals still had slight conjunctivae (scores 1, 1, 1). All eye irritation effects were fully reversible within 48 hours.
