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.

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.
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.
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.
