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 hygiene 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 product comprising a substrate and an antimicrobial composition disposed on said substrate, wherein said substrate is selected from the group consisting of a paper hand towel, a napkin, facial tissue, toilet paper and household paper towels, and wherein said composition is biodegradable, surfactant-free, and comprises a hydrophilic solvent in which is dispersed 2-phenylphenol and at least one additional phenol-based antimicrobial active agent.
2. The paper product according to claim 1 , wherein the phenol-based antimicrobial agent is selected from the group consisting of 2-phenylphenol, sodium-2-phenylphenolate, hexachlorophene, chlorhexidine, diphenyl ethers and mixtures thereof.
3. The paper product 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.
4. The paper product according to claim 1 , wherein the antimicrobial composition comprises from about 5% to about 95% by weight of the antimicrobial active agent.
5. The paper product according to claim 4 , wherein the antimicrobial composition comprises from about 5% to about 50% by weight of the antimicrobial active agent.
6. The paper product according to claim 1 , wherein the solvent comprises propylene glycol.
7. The paper product according to claim 1 , wherein the antimicrobial composition further comprises a carrier.
8. The paper product according to claim 7 wherein the carrier comprises polyethylene glycol and the antimicrobial composition comprises about 0.1% to about 90% of the carrier by weight.
9. The paper product according to claim 8 wherein the carrier comprises polyethylene glycol and the antimicrobial composition comprises about 16% to about 30% of the carrier by weight.
10. The paper product according to claim 7 , wherein the carrier is selected from the group consisting of PEG200, PEG400, PEG600, PEG3350, PEG8000 and mixtures thereof.
11. The paper product 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.
12. The paper product according to claim 1 , wherein said antimicrobial composition comprises 30 to 45% by weight of hydrophilic solvent, 30 to 45% by weight of antimicrobial agent, and 10 to 40% by weight of a carrier.
13. The paper product according to claim 1 , 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.
14. A method of preparing a paper product as defined in claim 1 , said method comprising applying to the paper substrate a biodegradable antimicrobial composition comprising a hydrophilic solvent in which is dispersed at least one phenol-based antimicrobial active agent.
15. The method of claim 14 , wherein said composition is applied to the substrate using a process selected from the group consisting of spraying, flexographic printing and roto gravure printing.
