Abstract
A non-irritating antimicrobial multi-layer or multi-ply tissue product made by treating an inner layer or ply or an inner surface of an inner layer or ply with one or more antimicrobial agents and treating the one or more outer layers or plies or the outer surfaces of the layers or plies with one or more irritation-inhibiting agents, and methods of making and using the same. The antimicrobial agent will remain confined to the inner portion of the tissue product, thereby preventing irritation to the user, and the irritation-inhibiting composition treated layer(s) or ply(s) provides a pleasing, soothing, non-irritating tactile quality to the tissue product. The non-irritating antimicrobial multi-layer or multi-ply tissue product further comprises an absorption enhancing agent. In one embodiment, the irritation-inhibiting composition comprises an oil, in which case the tissue product will also entrap any absorbed contaminant, holding it in contact with the antimicrobial agent.
