Sodium Hydrosulfite is a strong reducing agent widely used in bleaching, decolorizing, and specialty chemical applications. It is best known for its role in the textile industry, where it provides effective bleaching and whitening of both natural and synthetic fibers, and in the paper industry, where it is applied for de-inking and brightening recycled pulp. Its controlled reduction properties also make it valuable in leather processing, kaolin clay brightening, and other industrial treatments requiring high reactivity and precision.

Beyond bleaching, Sodium Hydrosulfite serves as a reagent and processing aid in chemical synthesis, water treatment, and food processing. Its versatility and adaptability allow it to be applied across diverse industrial systems. With its proven effectiveness and broad functionality, Sodium Hydrosulfite remains an indispensable material in textiles, pulp and paper, mining, environmental treatment, and specialty chemical manufacturing.
