A drawback of prior known carboxymethyl cellulose dispersions is that their carboxymethyl cellulose content is low, the stability is poor and the viscosity is too high for optimum use of the product. Now, those drawbacks have been eliminated by a new carboxymethyl cellulose slurry comprising: (a) about 10 to 60 %, based on the total weight of the slurry, of carboxymethyl cellulose, (b) about 40 to 60 %, based on the total weight of the slurry, of water soluble polyethylene glycol, the average molar mass of which is below about 1000 g/l, and (c) about 1 to 50 %, calculated as a solid and based on the total weight of the slurry, of an inert powder or dispersion. |
