Sodium Tetraborate Decahydrate is more popularly known as Borax10 mol. It is often used as a buffering agent. Borax decahydrate is utilized as a cleaning agent, especially for laundry purposes. Researchers may employ borax for surface treatment purposes, such as cleaning, etching, or modifying the surface properties of materials. Borax decahydrate serves as a preservative and pH buffer. It helps extend the shelf life of certain products and maintains their desired pH levels. Borax 10 mol is the least concentrated sodium borate product, because it has the most bound water (10 molecules). It is found in detergents, and personal care products. It is used to make glass, ceramics, and insulation. It is a flux in metal recovery, wire drawing and refractories. It is also a corrosion inhibitor in automotive antifreeze, and a preservative in casein-based adhesives.
