Abstract:
1. A process for forming a tissue product, comprising: applying a temporary wet strength agent to a pulp slurry, wherein the temporary wet strength agent is capable of forming hemi-acetal bonds with fibers of the pulp slurry in an amount effective to prevent immediate degradation of the tissue product upon contact with water; applying a degrading agent composition comprising a degrading agent, a degradation inhibiting carrier comprising a lotion or a cream, and a non-ionic surfactant in an amount effective to provide a viscosity of the degrading agent composition less than 3,000 cPs at 25° C. after 24 hours of storage, wherein the non-ionic surfactant is selected from the group consisting of: fatty acid polyoxyethylene sorbitan esters, fatty acid polyoxyethylene sorbitol esters, polyoxyethylene castor oils, alkylpolyoxyethylene amines, and amides, fatty acid sorbitan esters, fatty acid polyglycerin esters, fatty acid sucrose esters, polyethers-modified silicone-base surfactants, alkylaralkylpolyether-modified silicone-base surfactants, epoxypolyether-modified silicone-base surfactants, alcohol-modified silicone-base surfactants, fluorine-modified silicone-base surfactants, amino-modified silicone-base surfactants, mercapto-modified silicone-base surfactants, epoxy-modified silicone-base surfactants, allyl-modified silicone-base surfactants, perfluoroalkylethylene oxide adduct, and a combination thereof; and forming a tissue product, wherein the temporary wet strength agent and the degrading agent are in an amount effective to make the tissue product exhibit (i) an immediate wet tensile strength of at least 90% of the wet strength as compared to a tissue product that does not contain a degrading agent and (ii) a wet soak decay that is at least a ten point improvement as compared to a tissue product that does not contain a degrading agent, wherein wet soak decay is determined as the difference between the initial wet tensile strength and a thirty minute wet soak tensile strength as a percentage of the initial wet tensile strength.
