Abstract

A cleaner impregnated towel comprises a flexible, porous substrate and a cleaner, the cleaner comprising a salt of the coconut fatty acid ester of isethionic acid, an antimicrobial compound comprising 5-chloro-2-(2,4-dichlorophenoxy) phenol and parachlorometaxylenol, and water.

Claims

1. A cleaner impregnated towel, comprising:

a flexible, porous substrate; and

a cleaner impregnated into said substrate, said cleaner comprising;

from about 0.5 to about 90 weight percent salt of the coconut fatty acid ester of isethionic acid;

from about 0.1 to about 1 weight percent antimicrobial agent; and

from about 1 to about 99.5 weight percent water.

2. The cleaner impregnated towel according to claim 1, wherein the substrate is non-woven.

3. The cleaner impregnated towel according to claim 1, wherein the substrate comprises fibers selected from the group consisting of wood, silk, jute, hemp, cotton, linen, polyolefins, polyesters, rayon, cellulose ester, polyvinyl derivatives, polyamides, and combinations thereof.
