Used as a builder in detergents to enhance cleaning efficiency by softening water and preventing redeposition of dirt on surfaces. Acts as a corrosion inhibitor in metal cleaning formulations, protecting surfaces during cleaning processes. Employed in industrial cleaners for its alkaline properties, helping to break down grease, oil, and protein-based soils. Serves as a source of silicate in cement and concrete admixtures to improve setting properties and durability. Utilized in the production of silica gels and as a buffering agent to maintain alkaline pH in various formulations. Also found in some adhesives and refractory materials for improved stability and performance.
