Irritant / corrosive response data:
One hour after application if the test article all animals showed slight redness of conjunctivae. One animal additionally showed slight swelling of the conjunctivae. After 24 and 48 hours all animals showed slight redness of conjunctivae and only a slight swelling of conjunctivae was still visible. After 72 hours no eye reactions could be observed any more.
Other effects:
Discharge with moistening of lids and hairs, and considerable area around the eye was observed in the animal with swelling of the conjunctivae. Discharge with moistening of lids and hairs just adjacent to lids was observed in one of the other two animals, whereas the third animal only showed slight discharge.
