Paper product with disinfecting properties
View Patent ↗A paper product having an antimicrobial composition dispersed with the substrate is provided. In particular, a paper towel such as those found in public washrooms or institutions comprises an antimicrobial composition. The substrate can also be a facial tissue, kitchen towel, serviette or any type of personal hygeine product. The antimicrobial composition preferably comprises a phenol-derived antimicrobial agent. The paper products of the present invention appear dry to the touch.
1. A dry paper towel comprising a substrate and a single antimicrobial composition disposed on said substrate, wherein said composition is surfactant-free and said composition comprises a hydrophilic solvent in which is dispersed only a single antimicrobial active agent, wherein said antimicrobial active agent is 2-phenylphenol and wherein the paper towel exhibits a log 10 decrease in CFU/ml of at least about 0.1 for an exposure of 15 minutes.
2. The paper towel according to claim 1 , wherein the hydrophilic solvent is selected from the group consisting of methanol, ethanol, ethylene glycol, isopropanol, polyglycol, propylene glycol and mixtures thereof.
3. The paper towel according to claim 1 , wherein the antimicrobial composition comprises from about 5% to about 95% by weight of the antimicrobial active agent.
4. The paper towel according to claim 3 , wherein the antimicrobial composition comprises from about 5% to about 50% by weight of the antimicrobial active agent.
5. The paper towel according to claim 2 , wherein the solvent comprises propylene glycol.
6. The paper towel according to claim 1 , wherein the antimicrobial composition further comprises a carrier.
7. The paper towel according to claim 6 wherein the carrier comprises polyethylene glycol and the antimicrobial composition comprises about 16% to about 30% of the carrier by weight.
8. The paper towel according to claim 7 , wherein the carrier is selected from the group consisting of PEG200, PEG400, PEG600, PEG3350, PEG8000 and mixtures thereof.
9. The paper towel according to claim 1 , wherein the antimicrobial composition further comprises an additional component selected from the group comprising consisting of an alcohol, an emollient, a fragrance and combinations thereof.
10. A rolled product comprising the paper towel according to claim 1 .
11. A folded sheet product comprising the paper towel according to claim 1 .
12. A pre-packaged, single use product comprising the paper towel according to claim 1 .
13. A paper product that exhibits a log 10 decrease in CFU/ml of at least about 0.1 for an exposure of 15 minutes, said paper product comprising a substrate selected from the group consisting of a paper hand towel, a napkin, facial tissue, toilet paper and household paper towels and a single antimicrobial composition wherein said antimicrobial composition is surfactant-free and comprises 30 to 45% by weight of a hydrophilic anhydrous solvent in which is dispersed 30 to 45% by weight of only a single antimicrobial agent, wherein said agent is a phenol-based antimicrobial agent, and 10 to 40% by weight of a carrier.
14. The paper product according to claim 13 , wherein the antimicrobial composition comprises:
i) 35 to 42% by weight of 2-phenylphenol;
ii) 35 to 42% by weight of propylene glycol; and
iii) 16 to 30% by weight of a polyethylene glycol.
15. A dry paper towel comprising a substrate and a single antimicrobial composition disposed on said substrate, wherein said composition is biodegradable and surfactant-free, said composition comprising a hydrophilic solvent in which is dispersed a phenol-based antimicrobial active agent, wherein the paper towel exhibits a log 10 decrease in CFU/ml of at least about 0.1 for an exposure of 15 minutes.
16. The paper product according to claim 13 , wherein the phenol-based antimicrobial agent is selected from the group consisting of 2-phenylphenol, sodium-2-phenylphenolate, hexachlorophene, chlorhexidine or diphenyl ethers.
17. The paper product according to claim 15 , wherein the phenol-based antimicrobial agent is selected from the group consisting of 2-phenylphenol, sodium-2-phenylphenolate, hexachlorophene, chlorhexidine or diphenyl ethers.
18. A method of preparing an antimicrobial paper product as defined in claim 13 , said method comprising applying to the paper substrate the surfactant-free antimicrobial composition.
19. The method of claim 18 , wherein said composition is applied using a process selected from the group consisting of spraying, flexographic printing and roto gravure printing.
20. The method of claim 18 , wherein the paper product is a paper towel.
