Irritant / corrosive response data:
No corneal or iridial effects were noted during the study.
Other effects:
Residual test material was noted around the treated eye of one animal one hour after treatment.
Minimal conjunctival redness was noted in one treated eye one hour after treatment.

Any other information on results incl. tables

All treated eyes appeared normal at the 24-hour observation. Mean scores for all ocular lesions at 24, 48 and 72 hours were 0 for all animals.The test chemical was non-irritating to the eyes of rabbits.
