Sodium hypochlorite is one of the first, if not the first, chemical bleaching developed and produced in large amounts by the industry. It is one of the most powerful bleaching agents available and it is very much applied in the bleaching of pulp and paper and textile fibers. Thanks to its remarkable ability to eliminate stains and coloration, the product is also traditionally used in household cleaning to remove particularly resistant stains.


Sodium hypochlorite is also one of the most effective disinfecting agents. Its ability to pass through the cell membranes, joined to its high chemical potential, permits the product to kill practically every kind of microorganism, even at low temperature and low concentration. Due to that, sodium hypochlorite is widely used in industrial and household applications for fast and ensured disinfecting action. It is also widely used in the sterilization of potable water.
