: Key result
Test procedure:: other: Not specified
Remarks on result:: other: Chemical (CAS no. 93941-74-3) 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:: 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.
Executive summary:: 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.
