Abstract

The present invention relates to a fibrous matrix of synthetic detergents. The fibrous matrix includes fibers formed of a synthetic wax and a primary surfactant embedded in the fibers. The fibrous matrix further includes a secondary surfactant embedded in the fibers.

Claims (27)

1. A fibrous matrix of synthetic detergents, the fibrous matrix comprising:

fibers formed of a synthetic wax, wherein the fibers are completely soluble in aqueous media;

a primary surfactant embedded in the fibers; and

a secondary surfactant embedded in the fibers.

2. The fibrous matrix of claim 1 wherein the primary surfactant includes a surfactant monomer having a hydrophobic tail portion and a hydrophilic head group.

3. The fibrous matrix of claim 1 wherein the secondary surfactant includes a surfactant monomer having a hydrophobic tail portion and a hydrophilic head group.

4. The fibrous matrix of claim 1 wherein the synthetic wax is an ethylenic polymer.

5. The fibrous matrix of claim 1 wherein the fibers form a sheet.

6. The fibrous matrix of claim 5 wherein the sheet includes at least one fold.

7. The fibrous matrix of claim 5 wherein the sheet includes at least one perforation.

8. The fibrous matrix of claim 1 wherein the fibers form a continuous web.

9. The fibrous matrix of claim 8 wherein the continuous web is formed into a roll.

10. The fibrous matrix of claim 1 further comprising at least one additional ingredient embedded in the fibers.

11. The fibrous matrix of claim 1 wherein the at least one additional ingredient is an odor control ingredient.

12. The fibrous matrix of claim 1 wherein the fibers are in a substantially cylindrical form.

13. A fibrous matrix of synthetic detergents, the fibrous matrix comprising:

fibers formed of a synthetic wax, wherein the fibers are completely soluble in acqueous media;

a primary surfactant embedded in the fibers; and

a secondary surfactant embedded in the fibers, wherein the primary surfactant and the secondary surfactant are suspended in the fibers.

14. A fibrous matrix of synthetic detergents, the fibrous matrix comprising:

fibers formed of a synthetic wax, wherein the fibers are completely soluble in acqueous media;

a primary surfactant embedded in the fibers; and

a secondary surfactant embedded in the fibers, wherein the primary surfactant and the secondary surfactant are dissolved within the fibers.

15. A fibrous matrix of synthetic detergents, the fibrous matrix comprising:

fibers formed of a synthetic wax, wherein the fibers are completely soluble in acqueous media;

a primary surfactant embedded in the fibers; and

a secondary surfactant embedded in the fibers, wherein the fibers are arranged in an orthogonal pattern.
