Irritant / corrosive response data:
Slight to well-defined reddening of the conjunctival membranes was exhibited by 2 of 3 animals in which the treated eye remained unwashed. However, this effect failed to persist beyond 72 h after administration. No irritant responses were observed in any of the remaining individuals in this test group. No evidence of irritation to either the cornea or iris and no discharges were detected in treated animals with unwashed eyes. No irritating effects on cornea, iris and conjunctivae as well as no discharges were observed in treated animals with washed eyes. However, animals with washed eyes were not considered for classification, since test substance was already washed out 4 sec after test substance installation.
Other effects:
No further local or systemic effects were observed.
