Sodium carbonate decahydrate is widely used in the manufacturing of glass, where it acts as a flux to lower the melting point of silica, making the production process more energy-efficient. It is also a key ingredient in the production of detergents and soaps, where it helps to soften water by removing calcium and magnesium ions, enhancing the cleaning efficiency. In the textile industry, it is employed in dyeing and printing processes to fix dyes onto fabrics and to neutralize acidic conditions. Additionally, it is used in water treatment to adjust pH levels and in the food industry as a food additive for regulating acidity. Its ability to act as a cleaning agent makes it suitable for household cleaning applications, such as removing grease and stains from surfaces.
