- Irritant / corrosive response data:
- 1 h after test substance application all animals showed conjunctival redness scored with grade 1 which was fully reversible at the 72 h reading time point in all animals. Furthermore, two animals showed chemosis scored with grade 1, which was still visible in 1/3 animals at the 24 h reading time point. Afterwards, no chemosis was observed in any animal.
The examination for corneal injury using sodium fluorescein solution revealed no lesions in any of the animals at any timepoints. - Other effects:
- Clinicle signs
The observation of the general condition didn't disclose any abnormalities in any of the animals throughout the observation period.
Body weights
All of the animals gained body weight during the study.
