Applicant's summary and conclusion

Interpretation of results:
other: not sensitizing
Conclusions:
A skin sensitization test was conducted for the test material.The disodium 4,4'-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)amino]stilbene-2,2'-disulphonate observed to be non- sensitizing to human.
Executive summary:

The sensitization test was performed on 70 human by repeated insult patch test.10% of disodium 4,4'-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)amino]stilbene-2,2'-disulphonate in 0.5% vehicle was applied to 70 human subjects.For this test, the materials were applied under occlusive patches in a series of nine applications, each of 24 hours' duration, during a three-week period. Challenge applications were made two weeks later.Disodium 4,4'-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)amino]stilbene-2,2'-disulphonate tested did not reveal any tendency to produce skin sensitization among the human subjects who were exposed to the test material. Therefore Disodium 4,4'-bis [(4-anilino-6-morpholino- 1,3,5-triazin-2-yl) amino]stilbene-2,2'-disulphonate was considered to be non sensitizing to the human .
