Abstract

The personal care compositions of the present invention are in the form of an Article comprising a dissolvable fibrous web structure. The fibers of the dissolvable fibrous web structure comprise a surfactant; a water soluble polymeric structurant; and a plasticizer. Additionally the ratio of the water soluble water soluble polymeric structurant to the active agent in the fiber is 3.5 or less.

First claim

What is claimed is:

1. A solid, fibrous, lathering article comprising a multitude of random-length, interconnecting filaments comprising:
a. from 25% to about 50%, by weight of the article, of a water-soluble polymer comprising polyvinyl alcohol;
b. from about 40% to about 65%, by weight of the article, of an anionic surfactant comprising an acyl glutamate surfactant;
wherein the article is a personal care article;
wherein the dissolvable filaments comprise an average diameter of less than 150 micrometers;
wherein the article comprises a hand dissolution value of from about 1 to about 15 strokes.

2. The article of claim 1 , wherein the filaments comprise from about 25% to about 40%, by weight of the article, of the water-soluble polymer.

3. The article of claim 1 , wherein the water-soluble polymer comprises a weighted average molecular weight of from about 40,000 to about 500,000.

4. The article of claim 3 , wherein the water-soluble polymer comprises a weighted average molecular weight of from about 60,000 to about 300,000.

5. The solid fibrous article of claim 1 , wherein the filaments further comprise citric acid.

6. The solid fibrous article of claim 1 , further comprising a perfume.

7. The solid fibrous article of claim 1 , further comprising a dye.

8. The solid fibrous article of claim 1 , wherein the dissolvable filaments comprises a diameter of less than about 100 micrometers.

9. A solid, fibrous, lathering article comprising a multitude of random-length, interconnecting filaments comprising:
a. from 25% to about 50%, by weight of the article, of one or more water-soluble polymers chosen from polyvinyl alcohols, polyvinylpyrrolidones, or mixtures thereof;
b. from about 30% to about 65%, by weight of the article, of an anionic surfactant chosen from alkyl and alkyl ether sulfates, sulfonated olefins, acid taurates, acid isethionates, acyl glutamates, sodium lauroyl glutamate, or mixtures thereof;
wherein the article is a personal care article;
wherein the dissolvable filaments comprise an average diameter of less than 150 micrometers;
wherein the article comprises a hand dissolution value of from about 1 to about 15 strokes.

10. The solid fibrous article of claim 1 , wherein the composition further comprises a second anionic surfactant.

11. The solid fibrous article of claim 9 , wherein the dissolvable filaments comprises a diameter of less than about 100 micrometers.

12. A solid, fibrous, lathering article comprising a multitude of random-length, interconnecting filaments comprising:
a. from 25% to about 50%, by weight of the article, of one or more water-soluble polymers chosen from starch and starch derivatives, pullulan, hydroxypropylmethylcelluloses, or mixtures thereof;
b. from about 30% to about 65%, by weight of the article, of an anionic surfactant chosen from alkyl and alkyl ether sulfates, sulfonated olefins, acid taurates, acid isethionates, acyl glutamates, sodium lauroyl glutamate, or mixtures thereof;
wherein the article is a personal care article;
wherein the article comprises a hand dissolution value of from about 1 to about 15 strokes.
