He suffered serious chafing, and required treatment at the infield hospital after the victory lane celebration. 77, No. Borax is also easily converted to boric acid and other borates, which have many applications. Grade: Technical; Formula: Na2B4O7. Since people are already exposed to boric acid naturally through their diets and water, Health Canada advised that exposure from other sources should be reduced as much as possible, especially for children and pregnant women. Borax has been found at many other locations in the Southwestern United States, the Atacama desert in Chile, and in Bolivia, Tibet, and Romania. PubMed:Sensory and associated reactions to mineral dusts: sodium borate… "[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. The most commonly encountered one is the octahydrate Na2H4B4O9•8H2O or [Na(H2O)+4]2 [B4O5(OH)2−4] (or Na2B4O7•10H2O, the "decahydrate", in the older notation). Borax is a powdery white substance, also known as sodium borate, sodium tetraborate, or disodium tetraborate. Individual Protection Measures, Such as Personal Protective Equipment [28], 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. Borate buffers (usually at pH 8) are also used as preferential equilibration solution in dimethyl pimelimidate (DMP) based crosslinking reactions. Borax is also a good flux for "pre-tinning" tungsten with zinc — making the tungsten soft-solderable. Borax was added to the Substance of Very High Concern (SVHC) candidate list on December 16, 2010. It is mildly alkaline in solution. Sodium pentaborate pentahydrate. G. J. Gainsford, T. Kemmitt and C. Higham (2008): "Redetermination of the borax structure from laboratory X-ray data at 145 K". [17] It is poorly soluble in cold water, but its solubility increases significantly with temperature. In this structure, there are two four-coordinate boron centers and two three-coordinate boron centers. [33] In Indonesia, it is a common, but forbidden, additive to such foods as noodles, bakso (meatballs), and steamed rice. [34] Borax was one of the chemicals used in 19th century industrialised food production that was investigated by Dr. Harvey W.

[11], 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. Fibrous nodules of ulexite and proberite (sodium and calcium borate minerals) known as "cottonball" were found in salt deposits on the valley floor of California's Death Valley in the 1880s and taken to market on 20-mule team wagons. [58] It was proposed for addition to REACH Annex XIV by the ECHA on July 1, 2015. Pesticide properties for Sodium tetraborate pentahydrate, including approvals, environmental fate, eco-toxicity and human health issues [16] Borax is not used for this purpose in fireworks due to the overwhelming yellow color of sodium. sodium tetraborate pentahydrate sodium;tetraborate;pentahydrate .

Sodium tetraborate pentahydrate products used to pressure-treat wood for fungus or insect control have the potential to cause an exposure that is rated as moderate in hazard for toxicity. As well, new, more protective label directions are being introduced for other boric acid pesticides that continue to be registered in Canada (for example, enclosed bait stations and spot treatments using gel formulations).[61]. boric acid [1]; diboron trioxide [2]; tetraboron disodium heptaoxide, hydrate [3]; disodium tetraborate, anhydrous [4]; orthoboric acid sodium salt [5]; disodium tetraborate decahydrate [6]; disodium tetraborate pentahydrate … Ingredi BORAX Pentahydrate is branded Etibor-48 Granular manufactured and packaged by Etimine USA in a bulk 55.12 pound bag..

[12], The word tincal /ˈtɪŋkəl/ "tinkle", or tincar /ˈtɪŋkər/ "tinker", refers to crude borax, before it is purified, as mined from lake deposits in Tibet, Persia, and other parts of Asia. The formula is often improperly written as Na2B4O7•(n+2)H2O, reflecting an older incorrect understanding of the anion's molecular structure. [27] Borax is often used as a flux for forge welding. [59] If this recommendation is approved, all imports and uses of borax in the EU will have to be authorized by the ECHA. Borax, sodium tetraborate decahydrate, according to one study, is not acutely toxic. Borax is also used mixed with water as a flux when soldering jewelry metals such as gold or silver, where it allows the molten solder to wet the metal and flow evenly into the joint. On pesticide information websites it is listed as a non-lethal compound and of no hazardous concerns. The alkaline powder, also called sodium tetraborate or sodium borate, is a salt of boric acid. 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]. Borax, also called sodium tetraborate, is a powdery white mineral that has been used as a cleaning product for several decades. If you use hot water you can get a 4.4 M solution. "[60], A draft risk assessment released by Health Canada in July 2016 has found that overexposure to boric acid has the potential to cause developmental and reproductive health effects.
