Irritant / corrosive response data:
24 h after exposure, chemosis was observed in 4 of 6 animals, which disappeared the next day. All 6 animals showed redness of the conjunctivae, which dissapeared in 3 animals the next day. At 72 h observation, redness was still observed in 2 animals. Since the observation was stopped after 72 h, there is no information on the reversibility of these effects in the remaining 2 animals.
Adverse effects on the cornea and the iris were not observed in any of the animals.
