It interacts with keratin within the hair and weakens its structure for effective hair elimination.
Used in textile industries as a reducing agent in dyeing processes.
Helps in the reduction of the remaining dye and other contaminants on textile fibres.
Used in the pulp and paper industry to remove lignin from wood pulp.
Aids in the breakdown of lignin, thus enabling the separation of cellulose fibres during the paper manufacturing process.
Used in the extraction of ores through flotation and other mining processes.
Useful in the process of sorting valuable minerals from the gangue materials.
Applied in several chemical synthesis reactions as a reductant and sulphur donor.
Supports the synthesis of numerous chemical products.
Due to its sensitivity in handling, Sodium sulphide needs to be packed carefully to facilitate its transport and storage in industries. Aluminium Sulphate.
