In the detergent industry, it acts as a builder, enhancing the cleaning efficiency of soaps and detergents by softening water and maintaining pH levels. It is also employed in the glass manufacturing industry as a flux, lowering the melting point of silica and aiding in the production of glass. Additionally, it serves as a pH regulator in various chemical processes and is used in the textile industry for dyeing and printing fabrics. In food applications, it acts as a leavening agent in baking and as a stabilizer in certain processed foods. Its versatility makes it a valuable compound across multiple industries.
