Borax Decahydrate (Sodium Tetraborate Decahydrate)

Borax Decahydrate, chemically known as Sodium Tetraborate Decahydrate (Na2B4O7·10H2O), is an inorganic salt commonly supplied as a white crystalline granular powder. This compound is highly soluble in water, with a typical usage concentration ranging from 1–5% in detergent formulations to achieve effective water softening and alkalinity control. It is sensitive to moisture and must be stored in sealed containers to prevent caking and maintain stability. The product is not soluble in alcohol, which limits its compatibility with certain solvents. Industrial buyers should note its pH range in 1% aqueous solution consistently remains between 9.1 and 9.5, making it an ideal alkalinity buffer.

Borax Decahydrate is crucial in detergent formulation, specifically for softening hard water, which prevents mineral deposits that reduce detergent efficiency. By stabilizing alkaline pH, it enhances soil removal, directly impacting cleaning performance and lowering detergent consumption. In glass manufacturing, it lowers melting temperatures and improves product clarity, reducing energy costs and enhancing end-product quality. These properties help maintain process stability, reduce waste, and increase operational efficiency in manufacturing and treatment processes.
