Abstract

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

What is claimed is: 
     
         1 . A web material comprising a plurality of inter-entangled filaments associated with one another such that the web material is formed, wherein the plurality of inter-entangled filaments comprise one or more hair care active agents present in the plurality of inter-entangled filaments at a total level of greater than 20% by weight on a dry filament basis, wherein at least one of the hair care active agents comprises a surfactant, and one or more polar solvent-soluble filament-forming materials, and wherein the plurality of inter-entangled filaments exhibit 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 at least one of the one or more hair care active agents is releasable from the plurality of inter-entangled filaments when exposed to conditions of intended use. 
     
     
         3 . The web material according to  claim 1  wherein at least one of the one or more hair care active agents is selected from the group consisting of: shampoo agents and/or hair colorant agents, hair conditioning agents, and mixtures thereof. 
     
     
         4 . The web material according to  claim 1  wherein the plurality of inter-entangled filaments comprise two or more different hair care 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 . The web material according to  claim 1  wherein the plurality of inter-entangled filaments comprise a plurality of fibers. 
     
     
         8 . The web material according to  claim 1  wherein the plurality of inter-entangled filaments comprise at least one fiber. 
     
     
         9 . The web material according to  claim 1  wherein the plurality of inter-entangled filaments comprise a plurality of filaments, fibers, or combinations thereof. 
     
     
         10 . A web material comprising a plurality of inter-entangled filaments associated with one another such that the web material is formed, wherein the plurality of inter-entangled filaments comprise one or more hair care active agents present in the plurality of inter-entangled filaments at a total level of greater than 20% by weight on a dry filament basis, wherein at least one of the hair care active agents comprises a surfactant, and one or more filament-forming materials, and wherein the plurality of inter-entangled filaments exhibit 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. 
     
     
         11 . The web material according to  claim 10  wherein at least one of the one or more hair care active agents is releasable from the plurality of inter-entangled filaments when exposed to conditions of intended use. 
     
     
         12 . The web material according to  claim 10  wherein at least one of the one or more hair care active agents is selected from the group consisting of: shampoo agents and/or hair colorant agents, hair conditioning agents, and mixtures thereof. 
     
     
         13 . The web material according to  claim 10  wherein the plurality of inter-entangled filaments comprise a plurality of fibers. 
     
     
         14 . The web material according to  claim 10  wherein the plurality of inter-entangled filaments comprise at least one fiber. 
     
     
         15 . The web material according to  claim 10  wherein the plurality of inter-entangled filaments comprise a plurality of filaments, fibers, or combinations thereof. 
     
     
         16 . A web material comprising a plurality of inter-entangled filaments associated with one another such that the web material is formed, wherein the plurality of inter-entangled filaments comprise one or more hair care active agents present in the plurality of inter-entangled filaments at a total level of greater than 20% by weight on a dry filament basis, wherein at least one of the one or more hair care active agents comprises a surfactant, and one or more filament-forming materials, and wherein the plurality of inter-entangled filaments exhibit 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.
