Composition comprising water soluble polymer, such as cellulose ethers, guar, or derivatives thereof and surfactant, such as sorbitan esters, improves dispersibility of polymer in aqueous media.

Dispersible water soluble polymers

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.

Fluidized polymer suspensions of cationic polysaccharides in emollients

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.
