View Patent ↗A hair colorant composition comprises 2,6-diaminopyridine coupler in combination with 2-methoxymethyl-1,4-diaminobenzene developer. A kit for coloring hair comprises the hair colorant composition. A method of treating hair comprises applying the hair colorant composition to hair.
1. A hair colorant composition comprising:
(a) 2,6-diaminopyridine coupler;
(b) 2-methoxymethyl-1,4-diaminobenzene developer; and
(c) an oxidizing agent.
2. The hair colorant composition of claim 1 , comprising by weight, based on the weight of the hair colorant composition:
from 0.001% to 6% of said coupler;
from 0.001% to 6% of said developer; and
from 0.1% to 10% of said oxidizing agent.
3. The hair colorant composition of claim 1 , wherein said oxidizing agent is selected from the group consisting of hydrogen peroxide, inorganic and organic alkali-metal peroxides, inorganic perhydrate salts, alkyl and aryl peroxides, peroxidases, oxidases, and uricases and their substrates, percarbonates, persulfates, peroxymonocarbonates, and mixtures thereof.
4. The hair colorant composition of claim 1 , wherein said hair colorant composition comprises from 0.05% to 6% of said developer, based on the weight of the hair colorant composition.
5. The hair colorant composition of claim 1 , further comprising an alkalizing agent.
6. A method of treating hair, said method comprising:
(i) combining a tint composition with an oxidizing composition to form a hair coloring composition,
wherein said tint composition comprises 2,6-diaminopyridine coupler and 2-methoxymethyl-1,4-diaminobenzene developer, and
wherein said oxidizing composition comprises an oxidizing agent; and
(ii) contacting said hair with said hair coloring composition.
7. The method of claim 6 , further comprising separating a hair bundle from said hair, wherein said contacting of said hair comprises contacting said hair bundle with said hair coloring composition.
8. The method of claim 6 , wherein said hair is selected from the group consisting of a whole head of hair, a root portion of hair, and a hair bundle separated from a whole head of hair.
9. A hair coloring kit comprising:
(i) an individually packaged oxidizing composition comprising an oxidizing agent;
(ii) an individually packaged tint composition comprising:
(a) 2,6-diaminopyridine coupler; and
(b) 2-methoxymethyl-1,4-diaminobenzene developer.
10. The hair coloring kit of claim 9 , further comprising instructions for forming a hair coloring composition from the oxidizing composition and the tint composition.
11. The hair coloring kit of claim 9 , further comprising instructions for contacting hair with the hair coloring composition.
12. The hair coloring kit of claim 9 , further comprising an object selected from the group consisting of a mixing bowl, an application device, a dispensing device, gloves, hair-strand separators, and combinations thereof.
13. The hair coloring kit of claim 9 , wherein said oxidizing agent is selected from the group consisting of hydrogen peroxide, inorganic or organic alkali-metal peroxides, inorganic perhydrate salts, alkyl and aryl peroxides, peroxidases, oxidase, and uricases and their substrates, percarbonates, persulfates, peroxymonocarbonates, and mixtures thereof.
14. The hair coloring kit of claim 9 wherein said tint composition further comprises an alkalizing agent.
