Dialdehyde starch is a polysaccharidederived by chemical modification from starch. It is prepared by periodateoxidation of starch.[1] As an aqueous dispersion, it can form a particle gel or a polymer network depending on preparation conditions.[2]Hydrolysis with sulfurous acid yields glyoxal and erythrose.[3]
It has found use in the paper industry, where in it has been shown to improve the wet strength of consumer products like toilet paper and paper towels.[4]
