There are disclosed stable fluidized polymer suspensions containing cationic polysaccharide, stabilizing agent and emollient. The preferred cationic polysaccharides are cationic guar and cationic hydroxypropyl guar, and preferred emollients are hydrocarbons, silicone oils and esters. Processes for preparing personal care compositions utilizing the fluidized polymer suspensions are also disclosed. Using the fluidized polymer suspensions in the processes provides the advantages of more rapid dissolution and avoidance of lumps and gels when compared to using dry, powdered cationic polysaccharides.
L'invention porte sur des suspensions polymériques fluidifiées stables renfermant du polysaccharide cationique, un agent stabilisant et un émollient. Les polysaccharides à utiliser de préférence sont le guar cationique et le guar hydroxypropyle cationique; pour les émollients, on utilisera de préférence des hydrocarbures, des huiles de silicone et des esters. L'invention concerne des procédés de préparation de compositions faisant appel à des suspensions polymérisées fluidifiées. Comparées à des polysaccharides en poudre, ces suspensions polymérisées fluidifiées garantissent une dissolution plus rapide et évitent la formation de grumeaux et de gels.
