- Irritant / corrosive response data:
- 1 h post-instillation: some definitely hyperaemic (injected) blood vessels in 1 animal, diffuse, crimson red coloured mucous membranes (individual vessels were not easily discernible) in 2 animals. Swelling above normal of lids (and nictating membranes) and discharge in form of white mucous were observed in all 3 animals.
24-72 h post-instillation: the conjunctivae of all 3 animals still showed some definitely hyperaemic blood vessels.
6 days post-instillation: no more irritations on eye and mucous membrane were observed in any animal.
During the whole observation period, cornea and iris of all animals were free of any irritations. - Other effects:
- No further local or systemic effects were reported.
