Light green crystals that react with Carbon dioxide in the air. Sodium chlorite is used industrially for bleaching Paper pulp and textiles. Household bleach is a 5% aqueous solution of sodium hypochlorite (Clorox®, Dazzle, eau de Labarraque, etc.). Commercially, bleach is commonly used as a Disinfectant and Fungicide. Sodium hypochlorite is rarely used in conservation, however, because it can leave residual Chlorine compounds.
