Description
Barium sulfide (BaS, CAS 21109-95-5, EC 244-214-4) is an inorganic salt of barium and sulfur, also known as Bariumsulfid or barium sulphide. It carries no assigned E-code and is classified under HS code 2830908500 within the Salts and Minerals category.
In leather processing, barium sulfide functions as a depilatory agent, breaking down the protein bonds in animal hides to remove hair during the unhairing stage. In pulp and paper production, it acts as a bleaching and whitening agent, reducing coloured impurities through its reducing sulfide chemistry. It also finds application in mining and metals processing as a chemical intermediate.
Barium sulfide is supplied as a white to grey-brown powder and is subject to REACH registration requirements for industrial use within the EU. Buyers should confirm supplier SDS documentation and purity grade specifications prior to procurement, as handling classifications vary by concentration and intended application.
