Irritant / corrosive response data:

None of the rabbits vocalized upon instillation of the test material. The left (control) eyes were free of evidence of ocular irritation and other findings for the duration of the study. An iridial reaction was noted in the treated eye of one female animal. There were no corneal findings. Minor conjunctival irritation was noted for all rabbits. All irritation was reversible and completely subsided by termination (day 3) or earlier.

Other effects:

There were no deaths during the study. There were no remarkable changes or differences observed in body weights during the study period.
