USES:

You can see the uses and properties in more detail in this section: Uses of Borax.

  • IN DETERGENTS

Borax is one of the ingredients of which most soaps, detergents and fabric softeners are composed. Borax is used because as an amphoteric compound (it reacts with acids and bases), it is a good pH regulator, as well as softening carbonates in water, allowing for greater cleanliness.
Borax is sometimes used as a detergent booster. Especially in case of using a very basic detergent, an enhancer such as borax is used to improve the properties of the detergent. Borax is also used for the manufacture together with sodium carbonate of household detergents.

  • IN JEWELLERY:

In gold and silver casting, borax is used to dissolve the oxides formed during the heating of gold and silver. It allows the molten material to flow over the mould and retains its lustre.
