Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The substance 6-Amino-4-hydroxy-2-naphthalene-6-sulfonic acid is considered not irritating to rabbit eyes.
- Executive summary:
Eye irritation test of 6-Amino-4-hydroxy-2-naphthalene-6-sulfonic acid was conducted in rabbit. 50 mg of test chemical was instilled into the conjunctival sac of 2 rabbits. One hour after application, slight reddening was observed, which cleared up completely after 3 days Hence, the substance 6-Amino-4-hydroxy-2-naphthalene-6-sulfonic acid was considered to be not irritating to rabbit eyes.
