Industry Derivatives of guar gum that have been further reacted are used in industrial applications, such as the paper and textile industries, ore flotation, the manufacture of explosives and hydraulic fracturing (fracking) of oil and gas formations. Guar gum is often crosslinked with boron or chromium ions to make it more stable and heat-resistant. The crosslinking of guar with metal ions results in a gel that does not block the formation and helps efficiently in formation cleaning process. Guar and its derivatives make gel complexes with ions of aluminium, zirconium, titanium, chromium and boron. The borate–guar reaction is reversible, and depends on the pH (hydrogen ion concentration) of the solution. This reaction is used to give the toy "slime" its consistency. Crosslinking of guar with borate occurs at high pH (approximately 9–10) of the solution. Guar gum has proven as useful substitute for locust bean gum (made from carob seeds).
