Abstract

A rigidifying chemical solution and method of incorporating it into a cellulosic material to form a substantially rigid material is disclosed. The rigid material is dissolvable in water and biodegradable in conventional wastewater treatment systems. The chemical solution includes a rigidifying agent, such as sugar, dissolved in an aqueous solvent. When the rigidifying solution is applied to a cellulosic material such as paper, the solvent functions to incorporate the rigidifying agent into the cellulosic material. When the material dries, a rigidifying residue remains to form a substantially rigid structure with the cellulosic material. The rigidified material may be used to make a wide range of disposable articles.
