Applicant's summary and conclusion

Interpretation of results:
other: Not irritating
Conclusions:
During experimental study 100 mg of test compound sodium 4-[(2-hydroxy-1-naphthyl)azo]benzenesulphonate was administered to eye of 3 male rabbits,no sign of irritation was observed during experiment thus it is concluded that sodium 4-[(2-hydroxy-1-naphthyl)azo]benzenesulphonate dose not classify as eye irritant.
Executive summary:

Sodium 4-[(2-hydroxy-1-naphthyl)azo]benzene sulphonate was used as a teat material to evaluate eye irritation potential .

The test material was administrated on the eye of 3 male rabbits in the concentration 100 mg . No sign of irritation was observed during experiment thus it is concluded that sodium 4-[(2-hydroxy-1-naphthyl)azo]benzenesulphonate dose not classify as eye irritant.
