Description of key information
A) Flammability: not flammable solid
Ditolylether disulfonic acid disodium salt, isomer mixture did not burn down or burn up when tested according to UN N.1.
B) Contact with water: does not emit flammable gases in contact with water
The flammability of a substance on contact with water is determined following the methods N.5 (UN-Manual of testing). However, in accordance with section 1 of REACH Annex XI, a study on flammability in contact with water does not need to be conducted as ditolylether disulfonic acid disodium salt, isomer mixture does not emit flammable gases in contact with water. Based on the structure ditolylether disulfonic acid disodium salt, isomer mixture does not contain metals or metalloids.
C) Pyrophoric properties: no pyrophoric properties
Pyrophoric properties are determined following the methods N.2 (UN-Manual of testing) or A.13 (EU-method). However, in accordance with section 1 of REACH Annex XI, a study does not need to be conducted as it is scientifically unjustified. Based on experience during handling and use of ditolylether disulfonic acid disodium salt, isomer mixture, no pyrophoric properties were observed. Ditolylether disulfonic acid disodium salt, isomer mixture is known to be stable at room temperature.

- non flammable
Additional information
Justification for classification or non-classification
Ditolylether disulfonic acid disodium salt, isomer mixture is not flammable, it has no pyrophoric property, and no flammability in contact with water; and hence no classification according to both Directive 67/548/EEC and GHS (Regulation EC 1272/2008).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
