other: non flammable

Conclusions:

2 -[[4 -[[4 -[[6 -anilino-1 -hydroxy-3 -sulpho-2 -naphthyl] azo]-1 -naphthyl] azo]-6 -sulpho-1 -naphthyl] azo] benzene-1, 4 -disulphonic acid, magnesium sodium salt 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 2 -[[4 -[[4 -[[6 -anilino-1 -hydroxy-3 -sulpho-2 -naphthyl] azo]-1 -naphthyl] azo]-6 -sulpho-1 -naphthyl] azo] benzene-1, 4 -disulphonic acid, magnesium sodium salt is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2 -[[4 -[[4 -[[6 -anilino-1 -hydroxy-3 -sulpho-2 -naphthyl] azo]-1 -naphthyl] azo]-6 -sulpho-1 -naphthyl] azo] benzene-1, 4 -disulphonic acid, magnesium sodium salt was considered non-flammable for chemical safety assessment.
