Alcohol-free anti-bacterial wipes
View Patent ↗An alcohol-free antibacterial wipe comprising a flexible fabric coated with a polymeric latex binder, and an aqueous antibacterial solution wherein the aqueous antibacterial solution is comprised of an effective amount of a cationic antibacterial agent and sufficient amount of a surfactant.
1. An alcohol-free antibacterial wipe comprising:
a flexible fabric substrate containing a latex binder; and
an aqueous antibacterial solution, wherein said aqueous antibacterial solution is comprised of an effective amount of a cationic antibacterial agent and a surfactant in an amount sufficient to produce a wet feel to a consumer without further wetting, and said binder is present in at least about 90% of the substrate thickness prior to the addition of the aqueous antibacterial solution to the substrate.
2. The wipe of claim 1 wherein the substrate is further comprised of a front surface and a back surface, and said binder is present on both of the surfaces.
3. The alcohol-free antibacterial wipe of claim 1 wherein
said flexible fabric substrate is comprised of rayon,
said cationic antibacterial agent is benzalkonium chloride, and
said surfactant is disodium lauroamphodiacetate.
4. The alcohol-free antibacterial wipe of claim 2 wherein the effective amount of benzalkonium chloride is, based upon the total weight of the aqueous antibacterial solution, from about 0.09% to about 0.15%.
5. The wipe of claim 1 wherein the binder is a polymer latex polymerized from at least one acrylic monomer.
6. The wipe of claim 1 wherein the binder is a polymer latex comprised of a mixture of a self-crosslinking acrylic emulsion polymer latex binder and an acrylic emulsion polymer latex binder.
7. A method of preparing an alcohol-free antibacterial wipe which comprises
(i) preparing a solution of a cationic antibacterial agent, a surfactant, and water; and
(ii) applying said solution onto a flexible fabric substrate containing a latex binder, wherein said binder is present in at least about 90% of the substrate thickness and wherein said surfactant is used in an amount sufficient to produce a wet feel to a consumer without further wetting.
8. The method of claim 7 which further comprises
(i) preparing a solution of, based upon the total weight of the solution, from about 0.21% to about 0.22% benzalkonium chloride, about 0.15% to about 0.3% disodium lauroamphodiacetate, and water; and
(ii) applying said solution onto a substrate comprised of rayon and containing a latex binder, wherein said binder is present in at least about 90% of the substrate thickness.
