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 ethylenediamine-N,N′-disuccinic acid (EDDS) and/or histidine, rinsing the shampoo composition from the hair, applying to the hair a conditioner composition comprising histidine, rinsing the conditioner composition from the hair, and applying to the hair a leave-on treatment comprising ethylenediamine-N,N′-disuccinic acid (EDDS).

First claim

What is claimed is:

1. A method of inhibiting copper deposition on hair and facilitating the removal of copper deposited on hair comprising:
a. applying to the hair a shampoo composition comprising:
i. from about 0.05% to about 0.2% of a compound selected from the group consisting of ethylenediamine-N,N′-disuccinic acid (EDDS), derivatives of ethylenediamine-N,N′-disuccinic acid (EDDS), salts of ethylenediamine-N,N′-disuccinic acid (EDDS), histidine, and mixtures thereof, 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; and
iii. from about 20% to about 95% of a first aqueous carrier, by weight of the shampoo composition;

b. rinsing the shampoo composition from the hair;
c. applying to the hair a conditioner composition comprising:
i. from about 0.05% to about 0.2% histidine, by weight of the conditioner composition;
ii. a conditioner gel matrix comprising:
1. from about 0.1% to about 20% of one or more high melting point fatty compounds, by weight of the gel matrix;
2. from about 0.1% to about 10% of a cationic surfactant system, by weight of the gel matrix; and
3. at least 20% of a second aqueous carrier, by weight of the gel matrix;

d. rinsing the conditioner composition from the hair; and
e. applying to the hair a leave-on treatment comprising:
i. from about 0.25% to about 0.5% of a compound selected from the group consisting of ethylenediamine-N,N′-disuccinic acid (EDDS), derivatives of ethylenediamine-N,N′-disuccinic acid (EDDS), salts of ethylenediamine-N,N′-disuccinic acid (EDDS), and mixtures thereof, by weight of the leave-on treatment;
ii. one or more rheology modifiers; and
iii. at least 20% of a third aqueous carrier, by weight of the leave-on treatment.

2. The method of claim 1 , wherein the conditioner composition comprises from about 0.1% to about 0.15% histidine, by weight of the conditioner composition.

3. The method of claim 1 , wherein the conditioner composition further comprises one or more additional benefit agents.

4. The method of claim 3 , 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.

5. The method of claim 3 , wherein the one or more additional benefit agents is an anti-dandruff agent.

6. The method of claim 1 , wherein the shampoo composition has a pH of from about 3.5 to about 5.

7. The method of claim 1 , wherein the shampoo composition has a pH of about 4.25.

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 first aqueous carrier is water.

10. The method of claim 1 , wherein the shampoo composition comprises from about 0.1% to about 0.15% of a compound selected from the group consisting of ethylenediamine-N,N′-disuccinic acid (EDDS), derivatives of ethylenediamine-N,N′-disuccinic acid (EDDS), salts of ethylenediamine-N,N′-disuccinic acid (EDDS), histidine, and mixtures thereof, by weight of the shampoo composition.

11. The method of claim 1 , 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 1 , wherein the shampoo composition comprises about 0.1% of the compound selected from the group consisting of ethylenediamine-N,N′-disuccinic acid (EDDS), derivatives of ethylenediamine-N,N′-disuccinic acid (EDDS), salts of ethylenediamine-N,N′-disuccinic acid (EDDS), histidine, and mixtures thereof, by weight of the shampoo composition; wherein the conditioner composition comprises about 0.1% histidine, by weight of the conditioner composition; and wherein the leave-on treatment comprises about 0.5% of the compound selected from the group consisting of ethylenediamine-N,N′-disuccinic acid (EDDS), derivatives of ethylenediamine-N,N′-disuccinic acid (EDDS), salts of ethylenediamine-N,N′-disuccinic acid (EDDS), and mixtures thereof, by weight of the leave-on treatment.
