Sodium tetraborate is the refined form of natural sodium borate. Composed of
boric oxide (B2O3), sodium oxide, and water, it is a mild, alkaline salt, white and
crystalline, with excellent buffering and fluxing properties. Available in powder or
granular form.Borax Decahydrate is an important multifunctional source of B2O3,
particularly for processes in which the simultaneous presence of sodium is
beneficial.Borax decahydrate , also known as sodium borate, is an important
boron compound, a mineral, and a salt of boric acid.Powdered borax is white,
consisting of soft colorless crystals that dissolve easily in water.

sodium tetraborate 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 intocommon use in the late 19th century whenFrancis
Marion Smith's Pacific Coast Borax Company began to market and popularize a
large variety of applications.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 precursor for other boron compounds,
and along with its inverse, boric acid, is useful as an insecticide.In artisanal gold
mining, the borax method is sometimes used as a substitutefor toxic mercury in
the gold extraction process. Borax was reportedly used by gold miners in parts of
the Philippines in the 1900s.

1. Borax Decahydrate is chemically stable under normal storage conditions. It will
slowly lose water of crystallisation if exposed to a warm, dry atmosphere.
Conversely, exposure to a humid atmosphere can cause recrystallisation at particle
contact points, resulting in caking. When storing the product, care should therefore
be taken to avoid wide fluctuations in temperature and humidity, and to ensure that
the packaging is not damaged.
2. Dissolved in water, Borax Decahydrate hydrolyzes to give a mildly alkaline
solution. It is thus capable of neutralizing acids. It also combines with strong alkalis
to form compounds of lower pH. The relatively constant pH of Borax Decahydrate
solutions makes it an excellent buffering agent
Personal care products
Borax Decahydrate is used in cosmetics, toiletries and pharmaceuticals. In contact
lens solutions, it is used in conjunction with boric acid as a gentle cleaner and
buffering agent. Borax is also used as a crosslinking agent to emulsify waxes and
other paraffins used as a base for lotions, creams and ointments.
Soap and detergents
Borax Decahydrate is incorporated in many cleaning products as a pH buffering
agent, to aid in the emulsification of oils, and as a gentle abrasive. Borax
Decahydrate is added to powdered hand soaps to remove medium to heavy soils
encountered in industrial operations. It is gentle to the skin, yet highly effective in
removing dirt.
