Water-Dispersible Polysaccharide Derivatives of Reduced Glyoxal Content, and a Process for Decreasing the Glyoxal Content in Glyoxal-Crosslinked Polysaccharide Derivatives

摘要

The present invention is adjusting the pH, depending on the combination, and when the unbonded glitches to reduce the oxalate, at least one or more water-soluble aluminum salt, or one or more water-soluble borates, or one or more water-soluble aluminum salt and at least a water-soluble borate the drying after the treatment with an aqueous solution comprising a buffer substance suitable for, glyoxal-treated polysaccharide derivatives relates to. ; In addition, the present invention is the glyoxal-relates to a method for reducing the content in the unbound glyoxal-treated polysaccharide derivatives. ; Content of unbound glyoxal, glyoxal-cross-linked polysaccharide derivatives, cellulose ethers, glyoxal, borate, aluminum salts, buffer substances
