Applicant's summary and conclusion

Interpretation of results:
not irritating
Executive summary:

Thyssen/Bayer AG (1979):

In an acute eye irritation study, 50 mg of phthalimide (purity not stated) was placed in the conjunctival sac of two rabbits. Animals were observed for 7 days. Irritation was scored according to the method of Draize. No eye irritation was observed at any time point.
