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) about 0.025% to about 0.2% histidine, by weight of the shampoo composition;   b) about 2% to about 50% of one or more detersive anionic surfactants, by weight of the shampoo composition; and   c) a gel matrix comprising:
 i) about 0.1% to about 20% of one or more fatty alcohols, by weight of the gel matrix; 
 ii) about 0.1% to about 10% of one or more gel matrix surfactants, by weight of the gel matrix; and 
 iii) 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 fatty alcohol has 16 to 22 carbon atoms. 
     
     
         3 . The shampoo composition of  claim 1 , further comprising a cationic deposition polymer selected from the group consisting of polyquatemium-6, guar hydroxypropyltrimonium chloride, starch, polyquatemium-10, and combinations thereof. 
     
     
         4 . The shampoo composition of  claim 1 , further comprising one or more additional benefit agents selected from the group consisting of anti-dandruff agents, vitamins, chelants, perfumes, brighteners, enzymes, sensates, attractants, anti-bacterial agents, dyes, pigments, bleaches, and combinations thereof. 
     
     
         5 . The shampoo composition of  claim 4 , wherein the one or more additional benefit agents comprises an anti-dandruff agent selected from the group consisting of pyridinethione salts, azoles, selenium sulfide, sulfer, piroctone olamine, and combinations thereof. 
     
     
         6 . The shampoo composition of  claim 1 , further comprising a silicone conditioning agent. 
     
     
         7 . The shampoo composition of  claim 1 , further comprising citric acid. 
     
     
         8 . The shampoo composition of  claim 1 , wherein the shampoo composition has a pH of from about 5.25 to about 7. 
     
     
         9 . The shampoo composition of  claim 1 , wherein the aqueous carrier is water. 
     
     
         10 . The shampoo composition of  claim 1 , further comprising an amphoteric cosurfactant. 
     
     
         11 . 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.
