The purpose of this study was to observe how three hydrocolloids (Kelgin Q series, Procoat 150, and Dow 650) function in their control of water retention in clay systems. The water retention values were measured on a modified Warren tester. It was found that the three hydrocolloids are viscosity modifiers. However, their control of water retention is not due to their effect on viscosity, but rather, to their good water holding capabilities. Therefore, viscosity is not the primary parameter in control of water retention when using these hydrocolloids.
