Method of inhibiting copper deposition on hair

Abstract

A method of inhibiting copper deposition on hair and facilitating the removal of copper deposited on hair including applying to the hair a shampoo composition having histidine, rinsing the shampoo composition from the hair, applying to the hair a conditioner composition comprising histidine, and rinsing the conditioner composition from the hair.

What is claimed is: 
     
         1 . A method comprising:
 a. removing copper and inhibiting copper deposition on hair by applying to the hair a shampoo composition comprising:
 i. from about 0.025% to about 0.05% histidine, by weight of the shampoo composition; 
 ii. from about 2% to about 50% of one or more detersive surfactants, by weight of the shampoo composition; 
 iii. from about 20% to about 95% of an aqueous carrier, by weight of the shampoo composition; 
 iv. a shampoo gel matrix comprising:
 1. from about 0.5% to about 20% fatty alcohol, by weight of the shampoo gel matrix; and 
 2. from about 0.1% to about 10% of one or more shampoo gel matrix surfactants, by weight of the shampoo gel matrix; 
 3. from about 20% to about 95% of the aqueous carrier, by weight of the shampoo gel matrix;
 wherein the histidine penetrates inside the hair fiber forming a copper-chelant complex; 
 
 
   b. rinsing the shampoo composition and the copper-chelantfrom the hair thereby removing copper and inhibiting the copper deposition on the hair.   
     
     
         2 . The method of  claim 1 , wherein the shampoo composition further comprises one or more additional benefit agents. 
     
     
         3 . The method of  claim 2 , 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. 
     
     
         4 . The method of  claim 2 , wherein the one or more additional benefit agents is an anti-dandruff agent. 
     
     
         5 . The method of  claim 1 , wherein the shampoo composition has a pH of from about 3.5 to about 5. 
     
     
         6 . The method of  claim 1 , wherein the shampoo composition has a pH of about 4.25. 
     
     
         7 . The method of  claim 1 , wherein the shampoo composition has a pH of about 6. 
     
     
         8 . The method of  claim 1 , wherein the shampoo composition has a pH of from about 5.25 to about 7. 
     
     
         9 . The method of  claim 1 , wherein the aqueous carrier is water. 
     
     
         10 . A method comprising:
 c. removing copper and inhibiting copper deposition on hair by applying to the hair a shampoo composition comprising:
 i. from about 0.025% to about 0.05% histidine, by weight of the shampoo composition; 
 ii. from about 5% to about 20% detersive surfactant, by weight of the composition; wherein the detersive surfactant comprises sodium laureth sulfate and cocoamidopropyl betaine; 
 iii. from about 60% to about 95% of a first aqueous carrier, by weight of the shampoo composition; 
 iv. about 2%, by weight of the composition, of a shampoo gel matrix consisting of cetyl alcohol, stearyl alcohol, and the aqueous carrier; 
 v. a perfume;
 wherein the histidine penetrates inside the hair fiber forming a first copper-chelant complex; 
 
   d. rinsing the shampoo composition and the first copper-chelant from the hair thereby removing copper and inhibiting the copper deposition on the hair.   
     
     
         11 . The method of  claim 10 , wherein the shampoo composition further comprises one or more additional benefit agents. 
     
     
         12 . The method of  claim 11 , 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. 
     
     
         13 . The method of  claim 11 , wherein the one or more additional benefit agents is an anti-dandruff agent. 
     
     
         14 . The method of  claim 10 , wherein the shampoo composition has a pH of from about 3.5 to about 5. 
     
     
         15 . The method of  claim 10 , wherein the shampoo composition has a pH of about 4.25. 
     
     
         16 . The method of  claim 10 , wherein the shampoo composition has a pH of about 6. 
     
     
         17 . The method of  claim 10 , wherein the shampoo composition has a pH of from about 5.25 to about 7.
