Abstract

Fibrous elements containing one or more fibrous element-forming materials and one or more polyethylene oxides, and methods for making same are provided.

First claim

What is claimed is:

1 . A product comprising a fibrous structure comprising a plurality of fibrous elements, wherein the product comprises a total level of one or more active agents such that greater than 1 g of the total level of one or more active agents are delivered during use of the product.

2 . The product according to claim 1 wherein the product comprises a total level of one or more active agents such that greater than 3 g of the total level of one or more active agents are delivered during use of the product.

3 . The product according to claim 1 wherein the plurality of fibrous elements comprise one or more fibrous element-forming materials.

4 . The product according to claim 3 wherein at least one of the one or more fibrous element-forming materials comprises a polar solvent-soluble material.

5 . The product according to claim 4 wherein the polar solvent-soluble material comprises a water-soluble material.

6 . The product according to claim 3 wherein at least one of the one or more fibrous element-forming materials comprises a polymer.

7 . The product according to claim 6 wherein the polymer is selected from the group consisting of: pullulan, hydroxypropylmethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, polyvinyl pyrrolidone, carboxymethyl cellulose, sodium alginate, xanthan gum, tragacanth gum, guar gum, acacia gum, Arabic gum, polyacrylic acid, methylmethacrylate copolymer, carboxyvinyl polymer, dextrin, pectin, chitin, levan, elsinan, collagen, gelatin, zein, gluten, soy protein, casein, polyvinyl alcohol, starch, starch derivatives, hemicellulose, hemicellulose derivatives, proteins, chitosan, chitosan derivatives, polyethylene glycol, tetramethylene ether glycol, hydroxymethyl cellulose, and mixtures thereof.

8 . The product according to claim 7 wherein the polymer comprises polyvinyl alcohol.

9 . The product according to claim 1 wherein the plurality of fibrous elements comprises an extensional aid.

10 . The product according to claim 1 wherein the plurality of fibrous elements comprises one or more active agents.

11 . The product according to claim 10 wherein at least one of the one or more active agents is releasable from the plurality of fibrous elements when the plurality of fibrous elements is exposed to conditions of intended use.

12 . The product according to claim 10 wherein at least one of the one or more active agents is present within the plurality of fibrous elements.

13 . The product according to claim 10 wherein at least one of the one or more active agents is present on a surface of the plurality of fibrous elements.

14 . The product according to claim 10 wherein at least one of the one or more active agents comprises a surfactant.

15 . The product according to claim 14 wherein the surfactant is selected from the group consisting of: anionic surfactants, cationic surfactants, nonionic surfactants, zwitterionic surfactants, and mixtures thereof.

16 . The product according to claim 14 wherein the surfactant comprises a linear alkylbenzene sulfonate.

17 . The product according to claim 14 wherein the surfactant comprises an alkyl sulfate.

18 . The product according to claim 10 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.

19 . The product according to claim 1 wherein the fibrous structure further comprises a plurality of active agent-containing particles.

20 . The product according to claim 19 wherein at least one of the plurality of active agent-containing particles comprises an active agent selected from the group consisting of: surfactants, enzymes, builders, perfumes, suds suppressors, suds boosting agents, fabric softening agents, denture cleaning agents, hair cleaning agents, hair care agents, personal health care agents, hueing agents, bleaching agents, and mixtures thereof.

21 . The product according to claim 19 wherein at least one of the plurality of active agent-containing particle comprises a surfactant.

22 . The product according to claim 21 wherein the surfactant comprises a linear alkylbenzene sulfonate.

23 . The product according to claim 21 wherein the surfactant comprises an alkyl sulfate.
