Borax is used in various household laundry and cleaning products,
including the "20 Mule Team Borax" laundry booster, "Boraxo" powdered hand soap, and some tooth bleaching formulas.
Borate ions (commonly supplied as boric acid) are used in
biochemical and chemical laboratories to make buffers, e.g. for gel
electrophoresis of DNA and RNA, such as TBE buffer (borate buffered tris-hydroxymethylaminomethonium) or the newer SB
buffer or BBS buffer (borate buffered saline) in coating procedures. Borate buffers
(usually at pH 8) are also used as preferential equilibration
solution in dimethyl pimelimidate (DMP) based crosslinking reactions.
Borax as a source of borate has been used to take advantage of the co-complexing ability of
borate with other agents in water to form complex ions with various
substances. Borate and a suitable polymerbed are used to chromatograph non-glycosylated hemoglobin differentially from glycosylated hemoglobin (chiefly HbA1c), which is an indicator of long term hyperglycemia in diabetes mellitus.
Borax alone does not have a high affinity for the hardness cations, although it has been used for water-softening. Its chemical
equation for water-softening is given below:
Ca2+ (aq) + Na2B4O7 (aq) → CaB4O7 (s)↓ + 2 Na+ (aq)
Mg2+ (aq) + Na2B4O7 (aq) → MgB4O7 (s)↓ + 2 Na+ (aq)
The sodium ions introduced do not make water ‘hard’. This method is suitable
for removing both temporary and permanent types of hardness.
A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off. Borax is also used mixed with water as a
flux when soldering jewelry metals such as gold or silver. It allows the molten solder to flow evenly over the joint in question. Borax is also a good
flux for "pre-tinning" tungsten with zinc – making the tungsten soft-solderable. Borax is often
used as a flux for forge welding.
Small-scale gold mining
Borax is replacing mercury as the preferred method for extracting
gold in small-scale mining facilities. The method is called the borax method and is used in the Philippines.
A rubbery polymer sometimes called Slime, Flubber, 'gluep' or 'glurch' (or erroneously called Silly Putty, which is based on silicone polymers), can be made by cross-linking polyvinyl alcohol with borax. Making flubber from polyvinyl acetate-based glues, such as Elmer's Glue, and borax is a common elementary-science demonstration.
Borax, given the E number E285, is used as a food additive in some countries, but is banned in some countries, like the U.S.,
and Thailand. As a consequence, certain foods, such as caviar, produced for sale in the US contain higher levels of salt to assist preservation. Its use as a cooking ingredient is to add
a firm rubbery texture to the food, or as a preservative. In
oriental cooking it is mostly used for its texturing properties. In
Asia, borax was found to have been added to some Chinese foods like
hand-pulled noodles lamian and some rice noodles like shahe fen, kway teow, and chee cheong fun recipes. In Indonesia it is a common, but forbidden, additive to such foods as noodles, bakso (meatballs), and steamed rice. The country's Directorate of
Consumer Protection warns of the risk of liver cancer with high consumption over a period of 5–10 years.
