[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. Borax is also easily converted to boric acid and other borates, which have many applications. 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. [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. This lead up to the 1906 Pure Food and Drug Act. High purity and concentration, Available in small or large packaging. 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]. 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. Pulverized for the prevention of stubborn pests (e.g. Borax is replacing mercury as the preferred method for extracting gold in small-scale mining facilities. Its LD50 (median lethal dose) score is tested at 4.55-6.08 g/kg in rats as determined by US EPA (1969),[51] later in 1972 found to be 4.5 g/kg,[52] meaning that a significant dose of the chemical is needed to cause severe symptoms or death.
