Description

Guar gum, also called guaran, is a galactomannan polysaccharide extracted from guar beans. Guar gum shows a clear low shear plateau on the flow curve and is strongly shear-thinning. It is very thixotropic above 1% concentration, but below 0.3%, the thixotropy is slight. It is not affected by ionic strength or pH, but will degrade at extreme pH and temperature.It is insoluble in most hydrocarbon solvents. Due to it gelling properties guar gum finds extensive industrial application such as Textile industry ? sizing, finishing and printing, Paper industry ? improved sheet formation, folding and denser surface for printing, Explosives industry ? as waterproofing agent mixed with ammonium nitrate, nitroglycerin, etc.,Pharmaceutical industry ? as binder or as disintegrator in tablets; main ingredient in some bulk-forming laxatives, Cosmetics and toiletries industries ? thickener in toothpastes, conditioner in shampoos, Hydraulic fracturing Shale oil and gas extraction.
