Irritant / corrosive response data:
The application of the test substance to one eye of each animal did not result in corneal opacity, iritis or swelling of the conjunctivae at any observation time point. Very slight redness of the conjunctivae was observed in 1/4 animals at the 24 h reading time point. The effect was reversible within 48 h after the application of the test substance.
