Abstract
There are disclosed stable fluidized polymer suspensions containing cationic polysaccharide, stabilizing agent and water-soluble polyol. The preferred cationic polysaccharides are cationic guar and cationic hydroxypropyl guar. Processes for preparing personal care compositions utilizing the fluidized polymer suspensions are also disclosed. Using the fluidized polymer suspensions in the processes provides advantages of more rapid dissolution and avoidance of lumps and gels when compared to using dry, powdered cationic polysaccharides.
