- Irritant / corrosive response data:
- After 1 hour of treatment a redness and chemosis score of 2 was found in all animals. After 24 hours the chemosis was fully reversible and a mean conjunctival redness score of 1.3 (2/1/1) was found. After 48 hours only one animal showed a conjunctival redness score of 1 which was reversed after 72 hours. In the area of application no discoloration of the cornea and conjunctivae was observed which could be related to effects of the test article. No corrosion was observed at each of the measuring intervals.
- Other effects:
- No acute toxic symptoms were observed in the animals during the test period, and no mortality occurred. The body weight gain of all rabbits was similar.
