Description of key information
Liquid and solid: In accordance with column 2 of REACH Annex VII, the oxidising properties study (required in section 7.13.) does not need to be conducted as the substance is inorganic not containing oxygen or halogen atoms. The substance is manufactured and used as a 25% solution in water.
Key value for chemical safety assessment
Additional information
Expert judgement (instead of performing the test A.17):
From the expert view it is not necessary to perform the test A.17 experimentally. The following statement explains
the reason why. Oxidizing materials are either liquids or solids that readily give off oxygen or other oxidizing substances (such as
bromine, chlorine, or fluorine). They also include materials that react chemically to oxidize combustible (burnable)
materials; this means that oxygen combines chemically with the other material in a way that increases the chance of
a fire or explosion or at least it causes an acceleration of burning. The reaction may be spontaneous at either room
temperature or may occur under slight heating. Oxidizing materials can be severe fire and explosion hazards.
Examples for groups of common oxidizing materials:
bromine, bromates, chlorates, chromates, dichromates, hydroperoxides, hypochlorites, inorganic peroxides, ketone peroxides, nitrates, nitric acid, nitrites, perborates, perchlorates, perchloric acid, permanganates, peroxides, peroxyacids, persulfates
The property of a substance to act as a fire accelerating oxidator is therefore dependent on the ability to oxidize combustible materials and herewith to react exothermically. Sodium polysulfide is usually obtained by melting of Sodium sulfide together with Sulfur.
Sulfur itself is not an oxidizer but is oxidizable itself (e.g. Sulfur dioxide or Sulfur trioxide).
If the Sodium polysulfide, for example, decomposed due to a fire, oxidation of the Sulfur would clearly take place.
Justification for classification or non-classification
The test item is not capable of oxidizing other combustible materials. A classification of Sodium polysulfide as a solid oxidizer can be therefore excluded.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
