Borax (Sodium Tetraborate Decahydrate) is a naturally occurring mineral compound and one of the most versatile cleaning and formulation ingredients available. A white, crystalline powder that dissolves readily in warm water, it functions as a pH buffer, water softener, surfactant booster, and mild alkaline cleaner — making it an essential raw material for laundry products, industrial cleaning formulations, and household applications.

Laundry Applications

Laundry Booster Add 1–2 tablespoons directly to the wash drum alongside your regular detergent. Raises wash water pH, helping break down oils, grease, and protein-based stains more effectively.	Water Softener Sequesters calcium and magnesium ions in hard water, preventing soap scum and allowing surfactants to work at full potential. Reduces the amount of detergent needed per wash.
Whitening & Deodorising Inhibits odour-producing bacteria and helps maintain white fabric brightness without the harshness of chlorine bleach. Suitable for cottons and most synthetic blends.	Pre-Soak for Tough Stains Dissolve ½ cup in a bucket of warm water and soak stained garments for 30 minutes before washing. Effective on sweat stains, mildew, and ground-in dirt on workwear and uniforms.
DIY Detergent Formulation A key ingredient in homemade laundry powder when blended with washing soda and soap base. Contributes alkalinity and water-softening properties in formulations targeting cost-effective or eco-conscious cleaning.

Other Applications

General surface cleaning — Dissolve in water for bathroom tiles, grout, basins, and floors. Cuts through soap residue and mould.
Dishwasher powder base — Builder in auto-dishwash formulations to soften water and improve rinse performance.
Pest control — Applied in cracks and along skirting boards as a deterrent for ants and cockroaches.
Flame retardant treatment — Used in wood treatment and cellulose-based material processing for fire resistance.
Industrial/chemical formulation — pH buffering agent and builder in institutional cleaning product manufacturing.
