CA 2058326

A nonionic cellulose ether such as hydroxyalkylcellulose, alkylcellulose or an alkylhydroxyalkylcellulose hydrophobically modified with a C4 to C24 alkyl or an arylalkyl group is suspended by a low molecular weight polysaccharide and below 10% by weight salt to provide a fluidized polymer~suspension. the process for manufacture involves preparing an aqueous polysaccharide solution and adding a nonionic cellulose ether while stirring. Anionic, nonionic and cationic suspending polymers such as CMC, CM Guar, HEC and cationic starch may be used. Sodium carbonate is a preferred salt.
