ABSTRACT:
Guar gum as an exemplification of cis-1,2-diol polysaccharides is first hydrated then thickened by cross-linking with borax and finally dried to powder to flake form, preferably by freeze drying. The resulting particles can absorb up to 100 times their weight or more of aqueous fluids such as urine. Absorbent articles, such as disposable diapers, bandages, and the like are formed with the borax-cross-linked guar gum as absorbent. In a preferred diaper the dry absorbent particles of the borax cross-linked guar gum are placed in the cells of a cellular or bubble-type substrate.
