Applications of sodium hydrosulfite:

It is widely used in reductive dyeing, reductive cleaning, printing and decolorization in the textile industry and for bleaching of silk, wool, nylon and other fabrics. Because it does not contain heavy metals, the bleached fabrics are very bright in color and not easy to fade. In terms of various substances, it can also be used for food bleaching, such as gelatin, sucrose, candied fruit, and bleaching of soap, animal (vegetable) oil, bamboo ware, and porcelain clay. It can also be used in organic synthesis, such as the production of dyes and pharmaceuticals as a reducing agent or bleaching agent. Sodium hydrosulfite is the most suitable bleaching agent for wood pulp and papermaking.
