Guar gum also called Guaran, Cyamopsis gum, Guarina, Gluco tard and Guyan is a natural non-ionic, water soluble polysaccharide extracted from the refined endosperm of cluster bean seeds. Guar gum is a galactomannan consisting of a (1, 4)-linked b- D mannopyranose backbone with branch points from their 6- positions linked to a-D-galactose (i.e. 1, 6-linked-a-D-galactopyranose). Guar gum and its derivatives find great importance in a wide range of applications. In the petroleum industry, they were used as components in several formulations for corrosion inhibition, fracturing fluids, enhanced oil recovery and viscosity improvers. Recently, hydrophobically modified guar gum has been used in dispersant formulations. Yet, they have very little application as demulsifiers for petroleum emulsions.
