Sodium sulphide is commonly used in the pulp and paper industry for the manufacture of paper products. It is used as a bleaching agent and to remove lignin from wood pulp. In the textile industry it is used as a dyeing agent for cotton and wool fibres. In the leather industry, sodium sulphide 98% anhydrous is used to remove hair and feathers from animal skins and as a tanning agent. In addition, it is used in the production of sulphur dyes, insecticides and pharmaceuticals.
