Irritant / corrosive response data:
One hour after the treatment all animals displayed some hyperaemic blood vessels (score 1). In animal No.: 5304 the discharge moistened lids and hairs just adjacent to lids (score 2). Corneal and iris alterations were not recorded throughout the study period.
24 hours after the treatment in two animals (No.: 5327, 5304) conjunctival redness did not change when compared to the previous observation (scores 1-1). The discharge from the eye was greater than normal (score 1) in two animals (No.: 5327, 5304). In animal No.: 5327 some swelling above normal were found (score 1). The animal No.: 5301 became symptom-free.
48 hours after the treatment all animals were symptom-free.
72 hours after the treatment the study was terminated, as all animals were free of symptoms of irritation.
Other effects:
General state and the behaviour of animals were normal throughout the study period. There were no significant body weight changes during the
contact and observation period.
