Borax also known as sodium borate sodium tetraborate or disodium tetraborate is an important boron compound a mineral and a salt of boric acid. Powdered borax is white consisting of soft colorless crystals that dissolve in water. A number of closely related minerals or chemical compounds that differ in their crystal water content are referred to as borax and the word is usually used to refer to the octahydrate. Commercially sold borax is partially dehydrated.

Borax is a component of many detergents cosmetics and enamel glazes. It is used to make buffer solutions in biochemistry as a fire retardant as an anti-fungal compound in the manufacture of fiberglass as a flux in metallurgy neutron-capture shields for radioactive sources a texturing agent in cooking as a cross-linking agent in slime as an alkali in photographic developers as a precursor for other boron compounds and along with its inverse boric acid is useful as an insecticide.

Borax was first discovered in dry lake beds in Tibet and was imported via the Silk Road to the Arabian Peninsula in the 8th century AD. Borax first came into common use in the late 19th century when Francis Marion Smiths Pacific Coast Borax Company began to market and popularize a large variety of applications under the 20 Mule Team Borax trademark named for the method by which borax was originally hauled out of the California and Nevada deserts.
