Abstract

A web material containing one or more active agents and methods for making same are provided.

Claims (18)

1. A web material comprising a plurality of inter-entangled filaments associated with one another such that the web material is formed, wherein at least one of the filaments contains one or more active agents present in the filament at a total level of greater than 20% by weight on a dry filament basis, wherein at least one of the active agents comprises a surfactant, and one or more polar solvent-soluble filament-forming materials, and wherein the filament exhibits a diameter of greater than 1 μm and less than 100 μm as measured according to the Diameter Test Method and wherein the web material exhibits an average dissolution time less than 950 s/g as measured according to the Dissolution Test Method.

2. The web material according to claim 1 wherein one or more active agents are releasable from the filament when exposed to conditions of intended use.

3. The web material according to claim 1 wherein at least one of the one or more active agents is selected from the group consisting of: skin benefit agents, medicinal agents, lotions, fabric care agents, dishwashing agents, carpet care agents, surface care agents, hair care agents, air care agents, and mixtures thereof.

4. The web material according to claim 1 wherein the filament comprises two or more different active agents.

5. The web material according to claim 1 wherein the web material further comprises a dissolution aid.

6. The web material according to claim 1 wherein the web material exhibits a water content of from 0% to about 20% by weight as measured according to the Water Content Test Method.

7. A web material comprising a plurality of inter-entangled filaments associated with one another such that the web material is formed, wherein at least one of the filaments contains one or more active agents present in the filament at a total level of greater than 20% by weight on a dry filament basis, wherein at least one of the active agents comprises a surfactant, and one or more filament-forming materials, and wherein the filament exhibits a diameter of greater than 1 μm and less than 100 μm as measured according to the Diameter Test Method, wherein the web material exhibits a MD Peak Elongation of greater than 10% as measured according to the Elongation Test Method and wherein the web material exhibits an average dissolution time less than 950 s/g as measured according to the Dissolution Test Method.

8. The web material according to claim 7 wherein one or more active agents are releasable from the filament when exposed to conditions of intended use.

9. The web material according to claim 7 wherein at least one of the one or more active agents is selected from the group consisting of: skin benefit agents, medicinal agents, lotions, fabric care agents, dishwashing agents, carpet care agents, surface care agents, hair care agents, air care agents, and mixtures thereof.

10. The web material according to claim 7 wherein the filament comprises two or more different active agents.

11. The web material according to claim 7 wherein the web material further comprises a dissolution aid.

12. The web material according to claim 7 wherein the web material exhibits a water content of from 0% to about 20% by weight as measured according to the Water Content Test Method.

13. A web material comprising a plurality of inter-entangled filaments associated with one another such that the web material is formed, wherein at least one of the filaments contains one or more active agents present in the filament at a total level of greater than 20% by weight on a dry filament basis, wherein at least one of the active agents comprises a surfactant, and one or more filament-forming materials, and wherein the filament exhibits a diameter of greater than 1 μm and less than 100 μm as measured according to the Diameter Test Method, wherein the web material exhibits a GM Modulus of less than 15,000 g/cm 2 as measured according to the Modulus Test Method and wherein the web material exhibits an average dissolution time less than 950 s/g as measured according to the Dissolution Test Method.

14. The web material according to claim 13 wherein one or more active agents are releasable from the filament when exposed to conditions of intended use.

15. The web material according to claim 13 wherein at least one of the one or more active agents is selected from the group consisting of: skin benefit agents, medicinal agents, lotions, fabric care agents, dishwashing agents, carpet care agents, surface care agents, hair care agents, air care agents, and mixtures thereof.

16. The web material according to claim 13 wherein the filament comprises two or more different active agents.

17. The web material according to claim 13 wherein the web material further comprises a dissolution aid.

18. The web material according to claim 13 wherein the web material exhibits a water content of from 0% to about 20% by weight as measured according to the Water Content Test Method.
