Sodium hydrosulfite has a powerful reducing capacity and allows vat dyes to be reduced readily at room temperatures. It can also be used as antioxidants in hair treatment processes.
Sodium hydrosulfite is used in the bleaching of wood pulp. By reaction with formaldehyde, it produces rongalite that bleaches the wood pulp. This decreases the colour of the pulp so that it becomes whiter. This method is of high efficiency and is also known as reductive bleaching since reduction of the colour-causing compound causes it to lose its colour-causing property.
