Embodiment 1

[0153] Embodiment 1 is a wipe comprising (a) a substrate comprising a sponge, a woven fabric, or a nonwoven fabric, and (b) a cationic coating disposed on the On the surface of the substrate, distributed throughout at least a portion of the substrate, or both. The cationic coating comprises a guanidine-containing polymer that is crosslinked, covalently bound to the substrate, or both. When the wipe is in contact with an area of ​​a microbially-contaminated surface in the presence of a liquid, at least 99% of the microorganisms present on the microbially-contaminated surface are removed from the area by the wipe, and when the wipe No more than 0.2% of said microorganisms are transferred from said wipe to said second surface when the object contacts said area of ​​said microorganism-contaminated surface in the presence of said liquid and then contacts a second surface.

Embodiment 2

[0154] Embodiment 2 is the wipe of embodiment 1 wherein the guanidino-containing polymer is (a) a guanylation agent and (b) a carbonyl-containing polymer precursor or an amino group-containing polymer precursor reaction product.

Embodiment 3

[0155] Embodiment 3 is the wipe of any one of embodiments 1 or 2, wherein the guanidine-containing polymer is represented by Formula (I):

[0156]

[0157] where R 1 for hydrogen, C 1 -C 12 (hetero)alkyl, C 5 -C 12 (hetero)aryl, or the residue of the polymer chain; R 2 is a covalent bond, C 2 to C 12 (hetero)alkylene, or C 5 -C 12 (hetero)arylene; R 3 for hydrogen, C 1 -C 12 (hetero)alkyl, C 5 -C 12 (hetero)aryl, or when n is 0, it is the residue of the polymer chain; each R 4 independently hydrogen, C 1 -C 12 (hetero)alkyl, C 5 -C 12 (hetero)aryl; R 5 for hydrogen, C 1 -C 12 (hetero)alkyl, or C 5 -C 12 (hetero)aryl, or –N(R 4 ) 2 ; n is 0 or 1; m is 1 or 2; and x is an integer equal to at least 1.

Abstract

Disclosed is a wipe article comprising a substrate, a cationic coating disposed on the surface of the substrate, distributed throughout the substrate, or both. The cationic coating comprises a guanidine-containing polymer that is crosslinked and bonded to the substrate. The substrates include sponges, nonwoven fabrics, or woven fabrics. The wipes can be used to remove microbes from a microbiologically contaminated surface and can also be used to reduce recontamination of a cleaned surface or transfer of removed microbes to another surface.

Description

technical field [0001] The present disclosure relates to wipes having a cationic coating comprising a guanidinium-containing polymer. Methods of using the wipes and methods of making the wipes are also disclosed. Background technique [0002] Microbial contamination can be a problem in many fields of activity. Harmful microbial populations are a health hazard, can cause problems in pharmaceutical and food production, and can cause waste due to the deleterious effects of such bioactive microbial contamination on sensitive compositions and materials. Many surfaces can contain microbial residues in high enough numbers to contaminate sensitive products or processes. Elimination or removal of such microbial residues is a desired objective. [0003] In the medical industry, it is common practice to clean and / or disinfect environmental surfaces, medical instruments and devices to improve hygiene and patient safety. Effective disinfection must combat a broad spectrum of microorg...
