Personal Cleansing Compositions and Methods

Abstract

A personal care composition includes a surfactant, a water soluble cationic polymer, a hydrophobic benefit agent, and a hydrophobic cationic polyethylene polymer.

What is claimed is: 
     
         1 . A method of increasing coacervate rheology comprising:
 combining a surfactant, a water soluble cationic polymer, a benefit agent, and a cationic hydrophobic polyethylene polymer to form a personal care composition; and   diluting the personal care composition with water.   
     
     
         2 . The method of  claim 1 , wherein the personal cleansing composition is a multi-phase composition comprising a cleansing phase and a benefit phase, wherein the benefit agent and the cationic hydrophobic polyethylene polymer are in the cleansing phase. 
     
     
         3 . The method of  claim 1 , wherein the cationic hydrophobic polyethylene polymer comprises poly(ethylene-co-DMAEMA). 
     
     
         4 . The method of  claim 1 , wherein the composition comprises a pH of about 4.5 to about 9. 
     
     
         5 . The method of  claim 1 , wherein the cationic hydrophobic polyethylene polymer has a viscosity of about 100 cps or more at 120° C. 
     
     
         6 . The method of  claim 1 , wherein the cationic hydrophobic polyethylene polymer comprises an amino acrylate monomer. 
     
     
         7 . The method of  claim 6 , wherein the amino acrylate monomer comprises dimethylaminoethyl methacrylate, diethyleaminoethyl methacrylate, diethylaminoethyl acrylate, (4-hydroxyl-2,2,6,6-tetra-methylpiperidine) methacrylate, 2-Tert butyl amino ethyl methacrylate, or a combination thereof. 
     
     
         8 . The method of  claim 6 , wherein the cationic hydrophobic polyethylene polymer comprises at least about 30% or more of the acrylate monomer by weight of the hydrophobic cationic polyethylene polymer. 
     
     
         9 . A method of increasing encapsulation of a benefit agent in a coacervate, comprising:
 combining a surfactant, a water soluble cationic polymer, a benefit agent, and a cationic hydrophobic polyethylene polymer to form a personal care composition; and   diluting the personal care composition with water.   
     
     
         10 . The method of  claim 9 , wherein the composition comprises a pH of about 4.5 to about 9. 
     
     
         11 . The method of  claim 9 , wherein the cationic hydrophobic polyethylene polymer has a viscosity of about 100 cps or more at 120° C.
