Guar gum,also called guaran,is a galactomannan.It is primarily the ground endosperm of guar beans.It can be used in various multiphase formulations:as an emulsifier because it helps to prevent oil droplets from coalescing,and/or as a stabilizer because it helps to prevent solid particles from settling.
Chemically, guar gum is a polysaccharide composed of the sugars galactose and mannose. The backbone is a linear chain of β1,4-linked mannose residues to which galactose residues are 1,6-linked at every second mannose, forming short side-branches.
Guar gum is more soluble than locust bean gum and is a better stabilizer,In water, it is nonionic and hydrocolloidal. It is not affected by ionic strength or pH, but will degrade at pH extremes at temperature (e.g. pH 3 at 50 °C).It remains stable in solution over pH range 5-7. Strong acids cause hydrolysis and loss of viscosity, and alkalies in strong concentration also tend to reduce viscosity. It is insoluble in most hydrocarbon solvents.
Guar gum shows high low-shear viscosity but is strongly shear-thinning. It is very thixotropic above 1% concentration, but below 0.3%, the thixotropy is slight. It has much greater low-shear viscosity than that of locust bean gum, and also generally greater than that of other hydrocolloids. Guar gum shows viscosity synergy with xanthan gum.  
Guar gum is used as a thickener and emulsifier in commercial food processing. It has almost 8 times the thickening power as corn starch, and is used in dressings, sauces, milk products, and baking mixes. It is also used in food , pet food, oil drilling, construction, mining, beverage, paper manufacturing, textiles, printing, cosmetics and pharmaceuticals.
Industrial grade guar gum powder is suitable for use in oil well fracturing, oil well stimulation, mud drilling and serves as a stabilizer, thickener and suspending agent.
