Abstract

A method for perming or coloring hair, in which hair is treated with a cosmetic composition including a protein-glutaminase and not including an alkaline substance. A method of enhancing hair-permeation of an active ingredient included in a cosmetic composition, in which a protein glutaminase is included in the cosmetic composition. The cosmetic composition does not include an alkaline substance, and the active ingredient is at least one of a hair perm agent and a hair coloring agent.

First claim

The invention claimed is:

1. A method for perming or coloring hair, comprising:
treating hair with a cosmetic composition,
wherein the cosmetic composition comprises a protein-glutaminase, and the cosmetic composition is free of an alkaline substance and is free of a transglutaminase.

2. The method of claim 1 , wherein the cosmetic composition further comprises at least one of a hair perm agent and a hair coloring agent.

3. The method of claim 1 , wherein the protein-glutaminase has a molecular weight of 10 kDa to 40 kDa.

4. The method of claim 1 , wherein the protein-glutaminase is derived from a bacterium belonging to the genus Chryseobacterium.

5. The method of claim 1 , wherein the cosmetic composition further comprises a further component selected from the group consisting of an amino acid, an acylamino acid, an acylamino acid ester, an acylamino acid amide, a peptide, an acylpeptide, a salt thereof, and a combination thereof.

6. The method of claim 5 , wherein the cosmetic composition comprises 0.005 to 50 mass % of the further component, based on the total mass of the cosmetic composition.

7. The method of claim 1 , wherein the cosmetic composition further comprises an alcohol.

8. The method of claim 7 , wherein the cosmetic composition comprises 0.005 to 50 mass % of the alcohol, based on the total mass of the cosmetic composition.

9. The method of claim 7 , wherein the alcohol is a saturated or unsaturated monovalent C 1-6 alcohol or a polyvalent alcohol.

10. The method of claim 1 , wherein the cosmetic composition further comprises a hair coloring agent.

11. The method of claim 10 , wherein the hair coloring agent comprises p-phenylenediamine.

12. The method of claim 1 , wherein the hair is treated with the cosmetic composition to perm the hair.

13. The method of claim 1 , wherein the hair is treated with the cosmetic composition to change the color the hair.

14. A method of enhancing hair-permeation of an active ingredient included in a cosmetic composition, comprising:
including a protein-glutaminase in the cosmetic composition,
wherein the cosmetic composition is free of an alkaline substance and is free of a transglutaminase, and
the active ingredient is at least one of a hair perm agent and a hair coloring agent.

15. A method for treating human hair, comprising:
perming the human hair with a first perm composition comprising ammonium thioglycolate and at least one of aqueous ammonia and monoethanolamine and a second perm composition comprising sodium bromate;
applying to the permed hair a first composition comprising protein-glutaminase and not comprising an alkaline substance; and then
applying to the permed hair a second composition comprising transglutaminase,
wherein the first and second compositions applied to the permed hair are different.

16. The method of claim 15 , wherein the first composition applied to the permed hair comprises 0.00001 to 10 mass % of the protein-glutaminase, based on the total mass of the first composition applied to the permed hair.

17. The method of claim 15 , wherein the second composition applied to the permed hair comprises 0.001 to 2 mass % of the transglutaminase, based on the total mass of the second composition applied to the permed hair.

18. The method of claim 15 , wherein the first and second compositions are applied to the permed hair such that a mass ratio of the protein-glutaminase to the transglutaminase applied to the permed hair is from 1:1 to 1:10000.

19. The method of claim 15 , wherein the protein-glutaminase has a molecular weight of 10 kDa to 40 kDa.

20. The method of claim 15 , wherein the protein-glutaminase is derived from a bacterium belonging to the genus Chryseobacterium.
