- Irritant / corrosive response data:
- All animals: Nictitating membranes and conjunctive bluish stained up to 24 hours
Cornea minimally bluish stained in 5 rabbits on Day 1, still visible in 3 rabbits on Day 3. Due to the short post-observation period an the fact that the staining proved already to be reversible in 2 rabbits up to the end of the observation time. Full reversibility of the staining within a 21 day post-observation time is very likely. - Interpretation of results:
