Sodium tetraborate is widely used as a cleaning agent in household products, such as laundry detergents and multipurpose cleaners, due to its ability to soften water and enhance the effectiveness of cleaning. It is also a key ingredient in DIY slime recipes, acting as a cross-linking agent to create the desired texture. In the field of pest control, it serves as an effective insecticide, particularly against ants and cockroaches. Additionally, it is utilized in the manufacturing of fiberglass and ceramics, where it acts as a flux to reduce melting points and improve material properties. In metallurgy, it is employed as a flux for soldering and welding to remove metal oxides. Sodium tetraborate is also used in fire retardants and as a preservative in wood treatment to prevent fungal growth.
