Abstract

A wipe has a substrate, a treatment solution impregnated into the substrate, the treatment solution including an antifungal agent, an antifungal agent solvent, and a carrier fluid, wherein the treatment solution is essentially free of alcohol. A treatment solution, has an antifungal agent, an antifungal agent solvent, and a carrier fluid, wherein the treatment solution has an alcohol content of 6 wt % or below of the total solution.

Claims (25)

1. A wipe, comprising:

a substrate; and

a treatment solution impregnated into the substrate, the treatment solution comprising:

an antifungal agent comprising a naphtyl thiocarbamate;

a carrier fluid; and

an antifungal agent solvent comprising a dioxolane solvent miscible with the carrier and having a logKow with a range of −1 to 1, the dioxolane comprising one selected from the group selected from: 1,3-dioxolane, 4-Methyl-1,3-dioxolane, 2-methyl-1,3-dioxolane, (2-Methyl-1,3-dioxolane-4-yl) methanol, 1,3-Dioxepane, 1,3-Dioxolane-4-methanol, 5-Hydroxy-1,3-dioxane, Glycrol formal mixture (60:40) of 1,3-Dioxolane-4-methanol: 5-Hydroxy-1,3-dioxane, 1,4-dioxane, 1,3-dioxolane-2-one, and mixtures thereof;

wherein the treatment solution has an alcohol content of 6 wt % or below of the total solution.

8. The wipe claimed in claim 1 , wherein the substrate has a basis weight in the range of 40 to 60 grams per square meter.

9. A wipe, comprising:

a substrate; and

a treatment solution impregnated into the substrate, the treatment solution comprising:

an antifungal agent comprising a naphthyl thiocarbamate;

a carrier fluid; and

an antifungal agent solvent comprising a dioxolane solvent miscible with the carrier and having a logKow with a range of −1 to 1, the dioxolane comprising one selected from the group selected from: 1,3-dioxolane, 4-Methyl-1,3-dioxolane, 2-methyl-1,3-dioxolane, (2-Methyl-1,3-dioxolane-4-yl) methanol, 1,3-Dioxepane, 1,3-Dioxolane-4-methanol, 5-Hydroxy-1,3-dioxane, Glycrol formal mixture (60:40) of 1,3-Dioxolane-4-methanol:5-Hydroxy-1,3-dioxane, 1,4-dioxane, 1,3-dioxolane-2-one, and mixtures thereof.
