Abstract

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

Claims

1. A cleaner impregnated towel, consisting essentially of:

a flexible, porous substrate; and

a cleaner impregnated into said substrate, said cleaner consisting essentially of a salt of the coconut fatty acid ester of isethionic acid.

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.

4. The cleaner impregnated towel according to claim 1, wherein the substrate fibers have a Denier from about 1.5 to about 5.

5. The cleaner impregnated towel according to claim 1, wherein the substrate fibers have lengths from about 5 mm to about 50 mm.

6. The cleaner impregnated towel according to claim 1, wherein the salt comprises a salt selected from the group consisting of the sodium, potassium, and ammonium salts of the coconut fatty acid ester of isethionic acid, and mixtures thereof.

7. The cleaner impregnated towel according to claim 6, wherein the salt is sodium cocoyl isethionate.

8. A cleaner impregnated towel, consisting essentially of:

a flexible, porous substrate;

a cleaner impregnated into the substrate, said cleaner consisting essentially of a salt of the coconut fatty acid ester of isethionic acid; and

an antimicrobial compound impregnated into the substrate, said antimicrobial compound consisting essentially of

5-chloro-2-(2,4-dichlorophenoxy) phenol and parachlorometaxylenol.

9. The cleaner impregnated towel according to claim 8, wherein the substrate is non-woven.

10. The cleaner impregnated towel according to claim 8, wherein the substrate comprises fibers selected from the group consisting of wood, silk, jute, hemp, cotton, linen, polyolefins, polyester, rayon, cellulose ester, polyvinyl derivatives, polyamides, and combinations thereof.
