Abstract

A toilet seat cover is provided for preventing contact between the human buttocks and the toilet seat when the sheet is disposed and aligned with the toilet seat. A microbiocidal shield is created by the perspiration from the buttocks contacting a water-soluble oxidizing agent along with a water-soluble ene-diol compound dispersed as separate particles in the sheet. The water-soluble oxidizing agent and water-soluble ene-diol compound may be separately microencapsulated by a protective film. Capillary action of the fibers in the sheet provide for conducting free water released during reaction between the water-soluble oxidizing agent and the ene-diol compound throughout the toilet seat cover. Fibers of the sheet are adhesively bonded together within the adhesive that is soluble and dispersible in water to enable the toilet seat cover to be flushed down the toilet after use.
