Borax 10-hydrate (sodium tetraborate) 1 kg

Why Borax Remains a Staple Industrial and Household Reagent

Borax, chemically known as sodium tetraborate decahydrate, continues to be one of the most globally demanded mineral compounds thanks to its low cost and broad range of uses. The largest share of world consumption comes from industry: glass and ceramic glaze manufacturing, where the substance lowers the melting point of the batch, fireproofing treatments for wood and textiles, and metallurgy, where borax serves as a flux for soldering and welding non-ferrous metals. Agriculture forms another significant niche, using boron compounds as a micronutrient source for plant feeding. This 1 kg package of borax belongs to the Acids, Salts, Alcohols, and Alkalis section, which brings together fundamental chemical reagents for laboratory and manufacturing needs.

In household chemistry, sodium tetraborate is valued as an effective component of cleaning formulations and antiseptic treatments: it softens water, boosts the action of soap solutions, and inhibits mold growth on surfaces. Home crafters use borax solutions for making slime and polymer gels, combining them with polyvinyl alcohol glue to trigger near-instant crosslinking of polymer chains. In cosmetic manufacturing, borax acts as an emulsifier and pH stabilizer in beeswax-based creams: the classic wax-borax emulsion has remained a working formula for creams and balms for over a century. Typical dosage in cosmetic formulations stays around 0.5-1% of the wax weight, and the compound should be introduced into the water phase, pre-dissolved in warm water at 60-70 degrees, then combined with the melted oil phase at the same temperature.

When working with borax, it is worth considering its compatibility with other reagents from the same section: for precise pH correction of solutions and buffer systems, sodium lactate powder offers gentle adjustment without sharp shifts. In production laboratories, where borax serves as a reagent for analytical chemistry and for preparing buffer solutions used in titration, it is often paired with sodium hydrosulfite for reduction reactions. In the food industry of certain countries, subject to local regulations, sodium tetraborate has historically been used as a preservative, though today that role is more commonly filled by monosodium glutamate, which serves an entirely different function as a flavor enhancer.

The 1 kg package suits small manufacturing operations, cosmetic studios, and workshops handling small to medium batches, as well as agronomic and laboratory purposes where consumption rarely exceeds a few hundred grams per month. Borax should be stored in tightly sealed containers, in a dry place at room temperature, avoiding moisture exposure, since the compound tends to clump when exposed to humid air. Under proper storage conditions the shelf life is practically unlimited, as the compound is chemically stable and does not degrade over time.

Beeswax Hand Balm with Borax

Beeswax 25 g

Shea butter 20 g

Sweet almond oil 40 g

Borax 1 g

Distilled water 15 ml

Lavender essential oil 10 drops

Melt the beeswax, shea butter, and almond oil together in a double boiler at around 70 degrees until fully liquid. Separately heat the water to the same temperature and dissolve the borax in it, stirring thoroughly until the crystals disappear completely. Pour the water solution into the oil phase in a thin stream while whisking vigorously until a smooth white emulsion forms. Remove from heat, let the mixture cool to about 40 degrees, add the lavender essential oil, and stir once more. Transfer the balm into a jar and let it set at room temperature for several hours.
