- Irritant / corrosive response data:
- One hour after instillation of the test substance, slight conjunctivae redness and chemosis were observed in all animals. After 24 h and 48 h, slight conjunctivae redness was observed in 3 animals. At the 72 h reading timepoint, slight conjunctivae redness was observed in 2 animals. The effect was reversible in all animals within 7 days. The test substance did not affect the other irritation parameters in any animal at any timepoint.
Flurescein staining of the cornea was observed in three animals at the 48 h reading timepoint. At the 72 h reading, no staining of the cornea was observed indicating that the corneal response was superficial and transient. - Other effects:
- There were no clinical signs observed in any animal during the study period.
