Applicant's summary and conclusion

Interpretation of results:
other: not irritating
Conclusions:
Patent Blue V (CAS No: 129-17-9) was observed to be not irritating to rabbit skin.
Executive summary:

A skin irritation study was conducted in rabbits to observe the irritation potential of the Patent Blue V (CAS No: 129-17-9).

0. 5 ml of a saturated solution of the test chemical in saline was applied to rabbit skin (site not specified) and effects were observed (duration not specified).

Hence Patent Blue V (CAS No: 129-17-9) was considered to be not irritating to rabbit skin.
