Applicant's summary and conclusion
- Interpretation of results:
- other: not irritating
- Conclusions:
- In an eye irritation study, approx. 50mg 7-amino-4-hydroxy-2-naphthalenesulfonic acid was instilled into the eyes of the rabbits. No eye irritation was observed after 7 days. Hence the test chemical 7-Amino-4-hydroxy-2-naphthalenesulfonic acid (CAS No: 87-02-5) can be considered non-irritant to rabbit eyes.
- Executive summary:
An eye irritation test was conducted in rabbits for test chemical7-amino-4-hydroxy-2-naphthalenesulfonic acid(CAS No: 87-02-5) toassess the eye irritation potential.
In this study, 50 mg 7-amino-4-hydroxy-2-naphthalenesulfonic acid (I acid) was instilled into the conjunctival sac of 2 animalsandanimalswere observed for 7 days.
No eye irritation was observed after 7 days.Hence the test chemical 7-amino-4-hydroxy-2-naphthalenesulfonic acid(CAS No: 87-02-5)can be considered non-irritant to rabbit eyes.
