Derivatives of polissacaru00ecdeos dispersu00ecveis in water with low content of glyoxal and process for decreasing the content of glyoxal cross-linked with glyoxal derivatives polissacaru00ecdeos

摘要

"Derived from polissacaru00ecdeos dispersu00ecveis in water with low content of glyoxal and process for decreasing the content of glyoxal in glyoxal crosslinked with polissacaru00ecdeos derivatives.Described are derivatives of polysaccharides treated with glyoxal, which for the decrease of the glyoxal is not linked,Were treated with an aqueous solution of one or more water-soluble aluminum salts or with one or more water soluble borates, or a combination of one or more aluminium salts, water-soluble andOne or more water soluble borates and possibly with buffer substances suitable for adjusting the value of pH and dried.It is also described a process for decreasing the content of glyoxal not connected in derivatives of polysaccharides treated with glyoxal.
