Useful:

• Uses: The various hydrates of sodium metasilicate are used in soap, detergent, and bath/washing products. They also have a major use as a builder (a material that enhances or maintains the cleaning efficiency of the surfactant, principally by inactivating water hardness) in soaps and detergents. They are also used as an anticorrosion agent in boiler-water feeds. Sodium Metasilicate is an antibacterial pharmaceutical compound containing Sodium Hydrogen Carbonate. Laundry, dairy, and metal cleaning; floor clean- ing; base for detergent formulations; bleaching aid; deinking paper. Also available as the pentahydrate whose properties are mp 72.2C, total Na 2 O content 29.3%, total Na 2 O in active form 27.8%, d 1.75 or 55 lb/cu ft.
