Anti-microbial composition
View Patent ↗Anti-microbial compositions including an anti-microbial polymer containing silicon-containing quaternary ammonium groups, polyvinyl alcohol (PVA), at least one short chain alcohol, optional fragrance, and water are provided. The anti-microbial compositions may be used to disinfect both porous and non-porous surfaces. Exemplary compositions may include 0.1-10 wt % of the anti-microbial polymer containing silicon-containing quaternary ammonium groups, 0.1-10 wt % polyvinyl alcohol (PVA), 1.0-20 wt % isopropyl alcohol, optional fragrance, and water.
1. A liquid film forming anti-microbial composition consisting of:
1 wt. % of an anti-microbial polymer containing silicon-containing quaternary ammonium groups by weight of the composition;
1 wt. % polyvinyl alcohol (PVA) by weight of the composition;
10 wt. % ethanol by weight of the composition;
0-0.2 wt. % fragrance by weight of the composition; and
87.8-88 wt. % water by weight of the composition.
2. The liquid film forming antimicrobial composition of claim 1 wherein the anti-microbial polymer containing silicon-containing quaternary ammonium groups has the formula:
R 3 N + R 0 n SiX′ 4-n Y −
wherein each R and each R 0 is independently a non-hydrolysable organic group selected from an alkyl group of 1 to about 22 carbon atoms and an aryl group; n is an integer of 0 to 3; each X′ is —OR′, wherein R′ is selected from an alkyl group of 1 to about 22 carbon atoms, and an aryl group of 6 carbon atoms.
3. The liquid film forming antimicrobial composition of claim 2 wherein each R group is independently selected from methyl, ethyl, propyl, butyl, octyl, dodecyl, tetradecyl and octadecyl; each R 0 group is independently selected from methylenyl, ethylenyl, propylenyl, butylenyl, octylenyl, dodecylenyl, tetradecylenyl and octadecylenyl; and each X′ is —OR′, wherein R′ is selected from methyl, ethyl, propyl and butyl.
4. The liquid film forming antimicrobial composition of claim 1 wherein the anti-microbial polymer containing silicon-containing quaternary ammonium groups is polymeric 3-(trimethoxysilyl) propyldimethyloctadecyl ammonium chloride.
5. The liquid film forming antimicrobial composition of claim 1 wherein the composition has a viscosity of less than 4 cP.
6. A method of disinfecting a surface comprising applying a liquid film forming anti-microbial composition to the surface, the liquid film forming anti-microbial composition consisting of 1% by weight of an anti-microbial polymer containing silicon-containing quaternary ammonium groups, 1% by weight of polyvinyl alcohol (PVA), 10 wt. % ethanol, 0-0.2 wt. % fragrance, and 87.8-88% by weight water.
7. The method of claim 6 wherein the surface comprises a porous surface.
8. The method of claim 6 wherein the surface comprises a non-porous surface.
9. The method of claim 6 wherein the surface comprises a polyamide material.
