Abstract
A wiper having a controlled release anti-microbial agent therein for providing anti-microbial cleansing of surfaces is provided. The wiper is formed from an absorbent base web to which an anti-microbial formulation is adhered. The formulation includes an anti-microbial agent that is capable of being controllably released from the wiper. In some embodiments, a polymer mixture may be employed to control the rate of release of the anti-microbial agent. Various anti-microbial agents, such as metal ions and organic compounds may be employed.
