Abstract
A pre-moistened wiper that exhibits good antimicrobial kill at relatively small levels of antimicrobial agent is provided. In one embodiment, for example, the wiper contains a sanitizing formulation that includes between about 0.01% by weight to about 1% by weight of an antimicrobial agent, including a quaternary ammonium compound, and water. The sanitizing formulation is capable of being released from the wiper as a solution such that the quaternary ammonium compound is present within the solution in an amount less than about 2000 parts per million of the solution. The wiper can exhibit a log reduction for E. Coli of at least about 2.
Claims48
A wiper comprising a substrate and a sanitizing formulation applied to said substrate in an amount from about 150% to about 600% of the dry weight of the wiper, wherein said sanitizing formulation comprises water and between about 0.01% by weight to about 1% by weight of an antimicrobial agent that includes a quaternary ammonium compound, wherein said sanitizing formulation is capable of being released from said substrate as a solution such that said quaternary ammonium compound is present within said solution in an amount less than about 2000 parts per million of said solution, and wherein the wiper exhibits a log reduction for E. Coli of at least about 2.
A wiper comprising a nonwoven fabric and a sanitizing formulation applied to said nonwoven fabric in an amount from about 150% to about 600% of the dry weight of the wiper, said sanitizing formulation comprising between about 0.01% by weight to about 0.4% by weight of at least one benzalkonium halide, wherein said sanitizing formulation is capable of being released from said nonwoven fabric into a solution such that said benzalkonium halide is present within said solution in an amount less than about 2000 parts per million of said solution, and wherein the wiper exhibits a log reduction for E. Coli and S. Aureus of at least about 3.
A wiper comprising a nonwoven fabric and a sanitizing formulation applied to said nonwoven fabric in an amount from about 150% to about 600% of the dry weight of the wiper, said sanitizing formulation comprising between about 0.01% by weight to about 0.4% by weight of at least one benzalkonium halide, wherein said sanitizing formulation is capable of being released from said nonwoven fabric as a solution such that said benzalkonium halide is present within said solution in an amount less than about 2000 parts per million of said solution, and wherein the wiper exhibits a Kill Efficiency Ratio of at least about 100.
A method for sanitizing a surface, said method comprising:
- providing a wiper that contains a substrate applied with a sanitizing formulation in an amount from about 150% to about 600% of the dry weight of the wiper, said sanitizing formulation comprising between about 0.01% by weight to about 0.4% by weight of at least one quaternary ammonium compound;
- and
- moving said wiper across the surface such that at least a portion of said sanitizing formulation is released from said wiper to form a released solution, said released solution containing less than about 2000 parts per million of said quaternary ammonium compound, said released solution exhibiting a log reduction for E. Coli of at least about 2.
