Anionic, water-soluble cellulose ethers which are treated with a mixture of glyoxal and a sodium borate, preferably borax, readily disperse in aqueous solutions without clumping or agglomerating. These treated compounds can be formed by contacting an organic slurry of an anionic, water-soluble cellulose ether with an aqueous solution of glyoxal and a sodium borate, recovering the product and then drying it.
