Borax decahydrate

Borax is an important boron compound, a mineral, and a salt of boric acid. Borax Decahydrate, with a formula Na2B4O7.10H20, is the refined form of natural sodium borate.

Composed of boric oxide (B2O3), sodium oxide, and water, it is a mild, alkaline salt, white and crystalline, with excellent buffering and fluxing properties. Available in powder or granular form, Borax Decahydrate is an important multifunctional source of B2O3, particularly for processes in which the simultaneous presence of sodium is beneficial.

 

Applications of Borax decahydrate

Soap and detergents:
Borax Decahydrate is incorporated in many cleaning products as a pH buffering agent, to aid in the emulsification of oils, and as a gentle abrasive. Borax Decahydrate is added to powdered hand soaps to remove medium to heavy soils encountered in industrial operations. It is gentle to the skin, yet highly effective in removing dirt. Borax Decahydrate is added to formulations to clean hard surfaces such as metals, glass and ceramics. It is also used as an additive in hand cleaners, polishes and waxes, and industrial/institutional cleaning compounds. In laundry detergents it facilitates the removal of oily soils from fabrics, and imparts alkalinity, pH buffering and softening of the wash water. It is also used to stabilize enzymes.

Personal care products:
Borax Decahydrate is used in cosmetics, toiletries and pharmaceuticals. In contact lens solutions, it is used in conjunction with boric acid as a gentle cleaner and buffering agent. Borax is also used as a crosslinking agent to emulsify waxes and other paraffins used as a base for lotions, creams and
ointments.

Metallurgical fluxes:
The ability of Borax Decahydrate to dissolve metal oxides is exploited in the recovery of metals such as brass, copper, lead and zinc from scrap or smelting slag.

In ferrous metallurgy, Borax Decahydrate is used as a cover flux to prevent oxidation at the surface of the molten ingot. In welding, brazing, and soldering, Borax Decahydrate covers the metal surfaces, excluding air and preventing oxidation. It also acts as a solvent and cleaning agent.
