Abstract

Disclosed herein are methods for removing spores from skin, the method including dispensing an effective amount of a composition into or onto an article, wherein the composition includes water and from about 0.04 wt % to about 4 wt % polymeric cationic antimicrobial, nonionic antimicrobial or combinations thereof; contacting a skin surface with the composition; mechanically acting on the skin surface for at least one (1) second while the skin surface is in the presence of the composition; and removing at least a portion of the composition from the surface of the skin, wherein removing the composition also removes spores from the skin surface.

First claim

1 . A method for removing spores from skin, the method comprising:
dispensing an effective amount of a composition into or onto an article, wherein the composition comprises:
water; and
from about 0.04 wt % to about 4 wt % polymeric cationic antimicrobial, nonionic antimicrobial or combinations thereof;
contacting a skin surface with the composition; mechanically acting on the skin surface for at least one (1) second while the skin surface is in the presence of the composition; and removing at least a portion of the composition from the surface of the skin, wherein removing the composition also removes spores from the skin surface.

2 . The method according to claim 1 , wherein the composition comprises from about 0.04 wt % to about 0.3 wt % polymeric cationic antimicrobial.

3 . The method according to claim 2 , wherein the cationic antimicrobial is PHMB, or some combination thereof.

4 . The method according to claim 1 , wherein the composition comprises from about 0.5 wt % to about 4 wt % nonionic antimicrobial.

5 . The method according to claim 4 , wherein the nonionic antimicrobial is triclosan, PCMX, benzyl alcohol, phenoxyethanol, or some combination thereof.

6 . The method according to claim 1 , wherein the composition further comprises from about 2 to about 20 wt % of a lower hydrocarbon chain alcohol.

7 . The method according to claim 6 , wherein the lower chain alcohol is a C 2 to C 5 alcohol, or mixture thereof.

8 . The method according to claim 1 , wherein the composition further comprises not greater than about 15 wt % of a surfactant.

9 . The method according to claim 1 , wherein the composition further comprises humectants, emulsifiers, or combinations thereof.

10 . The method according to claim 1 , wherein the composition is free of a non-polymeric cationic antimicrobial.

11 . A method comprising:
dispensing an effective amount of a composition into a container, wherein the composition comprises:
water; and
from about 0.04 wt % to about 4 wt % polymeric cationic antimicrobial, nonionic antimicrobial or combinations thereof;
contacting a skin surface with the composition in the container; mechanically acting on the skin surface for at least one (1) second while the skin surface is in the presence of the composition; and removing at least a portion of the composition from the surface of the skin.

12 . The method according to claim 11 , wherein at least about 5 mL of composition is dispensed into the container.

13 . The method according to claim 11 , wherein at least about 1 mL/10 cm 2 of the skin surface to be cleaned is dispensed into the container.

14 . The method according to claim 11 , wherein the step of removing is accomplished without an excess of water.

15 . The method according to claim 11 , wherein the step of removing leaves less than 3 mL of composition on the surface.

16 . A method comprising:
obtaining a spore removing article, the spore removing article being capable of carrying an effective amount of a composition, wherein the composition comprises:
water; and
from about 0.04 wt % to about 4 wt % polymeric cationic antimicrobial, nonionic antimicrobial or combinations thereof;
contacting a skin surface with the spore removing article and the composition; mechanically acting on the skin surface for at least one (1) second with the spore removing article; and removing the spore removing article from the surface of the skin.

17 . The method according to claim 16 , wherein the carrier is a wipe, a sponge, or a fibrous mat.

18 . The method according to claim 16 , wherein the step of obtaining a spore removing article comprises obtaining a carrier pre-moistened with the composition.

19 . The method according to claim 16 , wherein the step of obtaining a spore removing article comprises obtaining the spore removing article from a package comprising a plurality of spore removing articles.

20 . The method according to claim 16 , wherein the spore removing article is capable of carrying at least about 5 MI of composition.
