Xanthan and locust bean gums are polysaccharides able to produce aqueous solutions with high viscosity and non-Newtonian behaviour. When these solutions are mixed a dramatic increase on viscosity is observed, much greater than the combined viscosity of the separated polysaccharide solutions. In this
## Abstract Semiβdilute solutions of hydroxypropyl guar gum (HPGG), the most widely used derivative of naturally occurring guar galactomannan, were investigated with respect to their viscosity, yield stress and thixotropy. It was found that the shearβdependent viscosity behaviour under various HPGG
