Borax pentahydrate, also known as Etibor 48 or sodium tetraborate pentahydrate, is the most common form of sodium borate used in various industries. San Diego: Howell-North Books. All restrictions were removed in February 1986 due to the low toxicity of borax, as reported in two EPA documents relating to boric acid and borax.[53][54]. With this in mind, the department also announced that registrations for certain pesticides that contain boric acid, which are commonly used in homes, will have their registrations cancelled and be phased out of the marketplace. The formula is often improperly written as Na2B4O7•(n+2)H2O, reflecting an older incorrect understanding of the anion's molecular structure. Borax pentahydrate, also known as Etibor 48 or sodium tetraborate pentahydrate, is the most common form of sodium borate used in various industries. Borax can be produced synthetically from other boron compounds. The name “borax” is derived from the word “borak,” which means white in Persian. He suffered serious chafing, and required treatment at the infield hospital after the victory lane celebration. In addition to its use as a preservative, borax imparts a firm, rubbery texture to food.

Its reaction with hydrochloric acid to form boric acid is: The "decahydrate" is sufficiently stable to find use as a primary standard for acid base titrimetry.[15]. Borax is a component of many detergents, cosmetics, and enamel glazes. Borate buffers (usually at pH 8) are also used as preferential equilibration solution in dimethyl pimelimidate (DMP) based crosslinking reactions. [16] Borax is not used for this purpose in fireworks due to the overwhelming yellow color of sodium. Dissolves somewhat exothermically in water to give basic solutions. 12179-04-3 - QZSYXKPOZFXCDM-UHFFFAOYSA-N - Sodium tetraborate pentahydrate - Similar structures search, synonyms, formulas, resource links, and other chemical information. In artisanal gold mining, borax is sometimes used as part of a process (as a flux) meant to eliminate the need for toxic mercury in the gold extraction process, although it cannot directly replace mercury.

Kemmitt and C. Higham (2008): "Redetermination of the borax structure from laboratory X-ray data at 145 K". [needs update], Review of the boron toxicity (as boric acid and borates) published 2012 in Journal of Toxicology and Environmental Health concluded: "It clearly appears that human B [boron] exposures, even in the highest exposed cohorts, are too low to reach the blood (and target tissue) concentrations that would be required to exert adverse effects on reproductive functions. It is also known as one of the E number food additives E500. [12] Borax first came into common use in the late 19th century when Francis Marion Smith's 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.[13][14]. 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 is useful as an insecticide (similarly to boric acid). Naturally occurring borax is refined by a process of recrystallization.[22]. "[55] In the reevaluation, a study of toxicity due to overexposure was checked and the findings were that "The residential handler inhalation risks due to boric acid and its sodium salts as active ingredients are not a risk concern and do not exceed the level of concern..." but that there could be some risk of irritation to children inhaling it if used as a powder for cleaning rugs. Substances and mixtures imported into the EU which contain borax are now required to be labelled with the warnings "May damage fertility" and "May damage the unborn child". 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. Download.
