Shampoo composition comprising gel matrix and histidine

Abstract

A shampoo composition having from about 0.025% to about 0.25% histidine, by weight of the shampoo composition; from about 2% to about 50% of one or more detersive surfactants, by weight of the shampoo composition; and a gel matrix having from about 0.1% to about 20% of one or more fatty alcohols, by weight of the gel matrix; from about 0.1% to about 10% of one or more gel matrix surfactants, by weight of the gel matrix; and from about 20% to about 95% of an aqueous carrier, by weight of the gel matrix.

What is claimed is: 
     
         1 ) A shampoo composition comprising:
 a. from about 0.025% to about 0.25% histidine, by weight of the shampoo composition;   b. from about 2% to about 50% of one or more detersive surfactants, by weight of the shampoo composition; and   c. a gel matrix comprising:
 i. from about 0.1% to about 20% of one or more fatty alcohols, by weight of the gel matrix; 
 ii. from about 0.1% to about 10% of one or more gel matrix surfactants, by weight of the gel matrix; and 
 iii. from about 20% to about 95% of an aqueous carrier, by weight of the gel matrix; 
   wherein the shampoo composition inhibits copper deposition on hair and facilitates the removal of copper deposited on hair.   
     
     
         2 ) The shampoo composition of  claim 1 , wherein the shampoo composition comprises from about 0.05% to about 0.2% histidine, by weight of the shampoo composition. 
     
     
         3 ) The shampoo composition of  claim 1 , wherein the shampoo composition comprises from about 0.1% to about 0.15% histidine, by weight of the shampoo composition. 
     
     
         4 ) The shampoo composition of  claim 1 , wherein the aqueous carrier is water. 
     
     
         5 ) The shampoo composition of  claim 1 , wherein the shampoo composition further comprises one or more additional benefit agents. 
     
     
         6 ) The shampoo composition of  claim 5 , wherein the one or more additional benefit agents is selected from the group consisting of anti-dandruff agents, vitamins, chelants, perfumes, brighteners, enzymes, sensates, attractants, anti-bacterial agents, dyes, pigments, bleaches, and mixtures thereof. 
     
     
         7 ) The shampoo composition of  claim 5 , wherein the one or more additional benefit agents is an anti-dandruff agent. 
     
     
         8 ) The shampoo composition of  claim 1 , wherein the shampoo composition further comprises citric acid. 
     
     
         9 ) The shampoo composition of  claim 1 , wherein the shampoo composition has a pH of from about 5.25 to about 7. 
     
     
         10 ) A method of inhibiting copper deposition on hair and facilitating the removal of copper deposited on hair comprising:
 a. applying to the hair the shampoo composition of  claim 1 ; and   b. rinsing the shampoo composition from the hair.
