Classification and labelling of Sodium Hexahydroxoantimonate



Classification and labelling according to CLP/GHS

Remarks: The classification and labelling of sodium hexahydroxoantimonate is covered by a group entry in Annex VI of regulation (EC) 1272/2008, Index No. 051-003-00-9.

However, recently generated substance specific hazard data do not support the harmonised classification and labelling for this antimony compound as stated in Annex VI of regulation (EC) 1272/2008.

Therefore, an alternative proposal for the classification and labelling of sodium hexahydroxoantimonate based on substance specific data is provided as well.
