other: Chemical (CAS no. 76186-07-7) not ignited when the flame of bunsen burner having temperature of approximately 950°C was brought in contact with it.
Interpretation of results:
other: non flammable
Conclusions:
6 -[(2,4 -diaminophenyl)azo]-3 -[[4 -[[4 -[[7 -[(2,4 -diaminophenyl)azo]-1 -hydroxy-3 -sulpho-2 -naphthyl]azo]phenyl]amino]-3 -sulphophenyl]azo]-4 -hydroxynaphthalene-2 -sulphonic acid does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that 6 -[(2,4 -diaminophenyl)azo]-3 -[[4 -[[4 -[[7 -[(2,4 -diaminophenyl)azo]-1 -hydroxy-3 -sulpho-2 -naphthyl]azo]phenyl]amino]-3 -sulphophenyl]azo]-4 -hydroxynaphthalene-2 -sulphonic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 6 -[(2,4 -diaminophenyl)azo]-3 -[[4 -[[4 -[[7 -[(2,4 -diaminophenyl)azo]-1 -hydroxy-3 -sulpho-2 -naphthyl]azo]phenyl]amino]-3 -sulphophenyl]azo]-4 -hydroxynaphthalene-2 -sulphonic acid was considered non-flammable for chemical safety assessment.
Executive summary:
