Guar gum is needed for producing sufficient viscosity. Because less is required, costs are reduced. This would help explain its presence in so many things today. In addition to guar gum's effects on viscosity, its high ability to flow, or "deform", gives it very favorable rheological properties. It forms breakable gels when cross-linked with boron. It is used in various multi-phase formulations for hydraulic fracturing, in some as an emulsifier because it helps to prevent oil droplets from coalescing, and in others as a stabilizer to help prevent solid particles from settling and/or separating. Fracking entails the pumping of sand-laden fluids into
Guar gum for humans and animals. Because it is gluten-free, it's also used as an additive to replace wheat flour in baked goods. It has also been shown to be beneficial to health. It has been shown to reduce serum cholesterol and lower blood glucose levels. Additional benefits have been seen in one's efforts to lose weight where, when ingested, its water-absorbing properties cause it to swell in the stomach giving one that 'full' sensation sooner. Guar gum is economical as well. Because it has almost eight times the water-thickening ability of other agents, cornstarch for example, only a very small quantity
