Borax decahydrate is an odourless, water-soluble powder. Also known as sodium borate or disodium tetraborate, the crystalline compound aids the effects of household cleaners and detergents when mixed in warm or hot water (the hotter, the better).

Thanks to its non-reactive nature, you can mix borax with many cleaning agents including chlorine bleach. This mixture produces an effective stain removal and disinfectant for domestic laundry purposes. It also has a base pH of 9.5, which allows for an even spread of cleaning agent molecules over the stained surface. On the industrial front, borax decahydrate is used as a preservative and in manufacturing insecticides and disinfectants. It is also used in slime making, as a fungicide and is inflammable. Its white crystalline powder has a melting point of 741℃ and dissolves in water to form hydrogen peroxide.
