Irritant / corrosive response data:
Minor (grade 1) conjunctival irritation was noted for all animals at the one hour post instillation observation. The eyes of all animals appeared normal by 48-hours post-instillation. There were no corneal or iridial findings.
Other effects:
There were no deaths during the study. No animals vocalized upon instillation of the test article. There were no remarkable body weight changes observed during the study.
