Description of key information

From the experimental values of flammability, α,α-bis[4-(dimethylamino)phenyl]-4-(phenylamino)naphthalene-1-methanol (Solvent Blue 4)  ignited when the flame of bunsen burner having temperature of 950 deg C was brought in contact with it. Thus it can be concluded that α,α-bis[4-(dimethylamino)phenyl]-4-(phenylamino)naphthalene-1-methanol is flammable only at high temperature of about 950 deg C. However since such high temperatures are not found under normal circumstances of transportation and use, α,α-bis[4-(dimethylamino)phenyl]-4-(phenylamino)naphthalene-1-methanol was considered non-flammable for chemical safety assessment.

Additional information

From the experimental values of flammability,α,α-bis[4-(dimethylamino)phenyl]-4-(phenylamino)naphthalene-1-methanol ignited when the flame of bunsen burner having temperature of 950 deg C was brought in contact with it. Thus it can be concluded thatα,α-bis[4-(dimethylamino)phenyl]-4-(phenylamino)naphthalene-1-methanol is flammable only at high temperature of about 950 deg C. However since such high temperatures are not found under normal circumstances of transportation and use,α,α-bis[4-(dimethylamino)phenyl]-4-(phenylamino)naphthalene-1-methanol was considered non-flammable for chemical safety assessment.

Justification for classification or non-classification

From the experimental values of flammability, α,α-bis[4-(dimethylamino)phenyl]-4-(phenylamino)naphthalene-1-methanol (Solvent Blue 4) ignited when the flame of bunsen burner having temperature of 950 deg C was brought in contact with it. Thus it can be concluded that α,α-bis[4-(dimethylamino)phenyl]-4-(phenylamino)naphthalene-1-methanol is flammable only at high temperature of about 950 deg C. Thus, Solvent Blue 4 is considered to be non-flammable for the purpose of classification
