Antimicrobial surface treatment
A surface treatment powder comprising (a) about 50 wt. % or more of a percarbonate, perphosphate, persulfate, peroxide or perborate salt; (b) about 0.2-10 wt. % of a chlorinated isocyanurate salt; and (c) a bleach activator, and method of using same to inhibit the growth of a microorganism on a surface.
1. A method of inhibiting the growth of a microorganism on a surface comprising applying a surface treatment powder to the surface, wherein the surface treatment powder comprises:
(a) about 50 wt. % or more of a percarbonate, perphosphate, persulfate, peroxide or perborate salt;
(b) about 0.2-10 wt. % of a chlorinated isocyanurate salt; and
(c) a bleach activator.
2. The method of claim 1 , further comprising combining the surface treatment powder with water after applying the surface treatment powder to the surface.
3. The method of claim 1 , wherein the surface is concrete.
4. The method of claim 1 , wherein the microorganism is Listeria, S. enterica , or Escherichia coli.
5. The method of claim 1 , wherein the surface is a floor, drain, or counter of a food processing facility or dairy.
6. The method of claim 1 , wherein the surface treatment powder further comprises an alkaline pH adjuster.
7. The method of claim 6 , wherein the alkaline pH adjuster is a carbonate salt.
8. The method of claim 1 , wherein the surface treatment powder further comprises about 0.1-1 wt. % of a surfactant.
9. The method of claim 1 , wherein the surface treatment powder comprises about 50 wt. % or more of a percarbonate salt.
10. The method of claim 1 , wherein the surface treatment powder comprises about 75 wt % or more of a percarbonate, perphosphate, persulfate, peroxide or perborate salt.
11. The method of claim 1 , wherein the surface treatment powder comprises about 0.2-10 wt % of a dichloroisocyanurate salt.
12. The method of claim 1 , wherein the surface treatment powder comprises about 0.5-2 wt. % of a dichloroisocyanurate salt.
13. The method of claim 1 , wherein the bleach activator is tetra acetyl ethylene diamine (TAED).
14. The method of claim 1 , wherein the surface treatment powder comprises about 0.01-1 wt. % TAED.
15. The method of claim 1 , wherein the surface treatment powder comprises about 0.05-0.5 wt. % TAED.
16. The method of claim 1 , wherein the surface treatment powder is substantially free of quaternary ammonium compounds.
17. The method of claim 1 , wherein the surface treatment powder is substantially free of iodine or iodophors.
18. The method of claim 1 , wherein the surface treatment powder is substantially free of enzymes.
19. The method of claim 1 , wherein the surface treatment powder applied to the surface is combined with any amount of moisture.
20. The method of claim 1 , wherein the powder is applied to a moist or wet surface.
21. The method of claim 20 , wherein the surface is a floor, drain, or counter of a food processing facility or dairy.
22. The method of claim 1 , wherein the method further comprises combining the surface treatment powder with water by applying the powder to a moist or wet surface, and, to the extent water is added to the surface treatment powder, the amount of water is small so as to provide a powder:water volume ratio of not less than about 5:1 to about 20:1.
23. The method of claim 22 , wherein the surface is a floor, drain, or counter of a food processing facility or dairy.
24. The method of claim 23 , wherein the surface treatment powder comprises about 75 wt. % or more of a percarbonate, perphosphate, persulfate, peroxide or perborate salt.
25. The method of claim 24 , wherein the surface treatment powder comprises about 0.5-5 wt. % of a chlorinated isocyanurate salt.
26. The method of claim 25 , wherein the surface treatment powder comprises about 0.05-1 wt % of a bleach activator.
