Applicant's summary and conclusion
- Interpretation of results:
- slightly irritating
- Remarks:
- Migrated information
- Conclusions:
- Under the conditions of this study, the test substance was considered minimally irritating.
- Executive summary:
In a study conducted in 6 rabbits, undiluted DIDP produced only slight signs of irritation in the conjunctiva at 1, 4 and 24-hour observation time (redness score 1 or 2 and discharge at 1 hour, redness score 1 at 4 hours and redness score 1 in 1 animal at 24 hours). All the eyes were normal at 48, 72 and 96 hours.
