Abstract
Abstract Phosphated locust bean gum is cold water soluble and does not require heat or high shear to form viscous solutions in water. Blends of phosphated locust bean gum and xanthan gums are also cold water soluble and such blends will form highly viscous gels in water without the application of heat or high shear agitation. Such gels are useful as suspending media for a variety of materials, e.g., seeds used in fluid drilling planting operations.
