What is Borax Decahydrate
Borax decahydrate or disodium tetraborate decahydrate is one of the most common sodium borate ores with chemical formula Na2B4O7.10H2O. The physical properties of borax decahydrate is a white monoclinic crystal that is soluble in water. In nature, it occurs as borax mineral from evaporation of deposits produced by the repeated evaporation of seasonal lakes.
Reactions with acids and bases will produce borates and dehydration will produce pentahydrate Na2B4O7.5H2O and other lower hydrates. Borax decahydrate will decompos at 75 degree celcius.
The Uses of Borax Decahydrate
Detergent IndustryBorax is most known for its use in detergent industry as borax helps with the removal of oily soils from fabrics, imparts alkalinity, pH buffering, and softening of the wash water.
Cosmetics & ToiletriesBorax decahydrate is used as a cross linking agent to emulsify waxes and other paraffin as the base of lotions, creams, and ointments
