Wood treatment compositions having antimicrobial properties
View Patent ↗The present application relates to wood treatment. More specifically, the present application relates to wood treatment compositions having antimicrobial properties, methods using the same and wood products treated therewith. The present application includes a wood treatment composition comprising: an antimicrobial additive comprising at least one tannin; and a water-based solvent. The present application also includes a method for treating a wood product to stop or prevent microbial growth applying a wood treatment composition on the wood product, and optionally applying a wax; wherein applying the wood treatment composition comprises heating at least one surface of the wood product and impregnating the composition.
1 . A wood treatment composition comprising:
an antimicrobial additive comprising at least one tannin; and
a water-based solvent; wherein the antimicrobial additive is present in an amount of from 12% to 15% by weight of the composition.
2 . The wood treatment composition of claim 1 , wherein the at least one tannin is selected from the group consisting of Limonium delicatulum extract, Pinus radiata extract, Acacia mollissima extract, Coriaria nepalensis extract, Picea abies extract, Myrciaria jaboticaba extract, Anadenanthera macrocarpa extract, Spondias tuberosa extract, Mimosa tenuiflora extract, Acacia mearnsii extract, and combinations thereof.
3 . The wood treatment composition of claim 1 , wherein the at least one tannin is a mimosa tree extract.
4 . The wood treatment composition of claim 1 , wherein the water-based solvent comprises water, and a water-miscible solvent selected from ethylene glycol, ethanol, methanol, and mixtures thereof.
5 . The wood treatment composition of claim 1 , wherein the water-based solvent is water.
6 . The wood treatment composition of claim 1 , wherein the composition is saturated with the antimicrobial additive.
7 . The wood treatment composition of claim 1 , wherein the composition provides at least about 95% reduction in growth of microbes.
8 . The wood treatment composition of claim 7 , wherein the microbes are selected from the group consisting of Escherichia coli, Staphylococcus aureus, Salmonella enterica subsp. enterica serovar typhimurium, Enterobacter aerogenes, Salmonella enterica, K. pneumoniae, Pseudomonas aeruginosa , and combinations thereof.
9 . The wood treatment composition of claim 1 , wherein the composition provides at least about 99% reduction in growth of microbes.
10 . The wood treatment composition of claim 1 , wherein the at least one tannin is selected from the group consisting of Limonium delicatulum extract, Pinus radiata extract, Acacia mollissima extract, Coriaria nepalensis extract, Picea abies extract, Myrciaria jaboticaba extract, Anadenanthera macrocarpa extract, Spondias tuberosa extract, Mimosa tenuiflora extract, Acacia mearnsii extract, and combinations thereof; and wherein the water-based solvent is water.
11 . A wood product treated with the composition of claim 1 .
12 . The wood product of claim 11 having at least one surface treated with the composition.
13 . The wood product of claim 11 , wherein the wood product is a food-contacting wood surface.
14 . The wood product of claim 11 , wherein the wood product is a floor, a pallet, a cutting board, a wooden container.
