ABSTRACT:
Compounds comprising the oxidation product of a polysaccharide in which the hydroxyl groups in at least a portion of the repeating units of the polysaccharide are cis-hydroxyl groups, the oxidation product comprising aldehyde groups, are disclosed. The compounds are useful for imparting temporary wet strength to paper products. Preferred polysaccharides for use in the invention include guar gum and locust bean gum.
