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.
L'invention concerne des suspensions polymères stables fluidisées contenant un polysaccharide cationique, un agent stabilisateur et un polyol hydrosoluble. Les polysaccharides cationiques préférés sont le guar cationique et le guar cationique hydroxypropylé. L'invention concerne également des procédés de préparation de compositions de soins d'hygiène personnelle utilisant les suspensions polymères fluidisées. L'utilisation des suspensions polymères fluidisées dans ces procédés offre l'avantage d'une dissolution plus rapide et permet d'éviter la formation de grumeaux et de gels en comparaison aux polysaccharides cationiques secs en poudre.
